chore: bump version to 0.9.2

* fix: resolve GitHub release asset API URL for private repo downloads

For private or SSO-protected GitHub repos, browser release download URLs
redirect to HTML/SSO instead of the ZIP asset. This commit resolves the
asset via the GitHub REST API and downloads with Accept: application/octet-stream,
falling back to the original URL if the API call fails.

* fix: support direct GitHub REST release asset URLs in extension downloads

When a catalog download_url is already a GitHub REST release asset URL
(https://api.github.com/repos/<owner>/<repo>/releases/assets/<id>),
skip the release metadata lookup and download directly with
Accept: application/octet-stream. This complements the browser URL
resolution from the previous commit, covering catalogs that reference
the REST API directly.

DO NOT USE FOR: creating new extensions from scratch, or first-party extension work.'
+argument-hint: 'GitHub issue URL or number for the extension submission'
+---
+
+# Add Community Extension
+
+Process an extension submission issue and add or update it in the community catalog.
+
+## When to Use
+
+- A new `[Extension]` submission issue is filed
+- An existing extension submits an update issue (new version, changed metadata)
+- You need to add or update a community extension in `extensions/catalog.community.json` and `docs/community/extensions.md`
+
+## Procedure
+
+### 1. Fetch the submission issue
+
+Read the GitHub issue to extract all metadata:
+- Extension ID, name, version, description, author
+- Repository URL, download URL, homepage, documentation, changelog
+- License, required spec-kit version, optional tool dependencies
+- Number of commands and hooks
+- Tags
+
+### 2. Validate against publishing rules
+
+Check **all** of the following (per `extensions/EXTENSION-PUBLISHING-GUIDE.md`):
+
+| Check | How |
+|-------|-----|
+| Repository exists and is public | Fetch the repository URL |
+| `extension.yml` manifest present | Confirm in repo file listing |
+| README.md present | Confirm in repo file listing |
+| LICENSE file present | Confirm in repo file listing |
+| GitHub release exists matching version | Check releases on the repo page |
+| Download URL is accessible | Verify it follows `archive/refs/tags/vX.Y.Z.zip` pattern and release exists |
+| Extension ID is lowercase-with-hyphens only | Regex: `^[a-z][a-z0-9-]*$` |
+| Version follows semver | Format: `X.Y.Z` |
+| Submission checklists are all checked | Confirm in issue body |
+
+### 3. Determine if this is an add or update
+
+Search `extensions/catalog.community.json` for the extension ID.
+
+- **Not found** → this is a **new addition**. Proceed to step 4.
+- **Found** → this is an **update**. Proceed to step 4 but replace the existing entry in-place instead of inserting.
+
+### 4. Add or update `extensions/catalog.community.json`
+
+**New extension:** Insert the entry in **alphabetical order** by extension ID.
+
+**Update:** Replace the existing entry in-place. Update only the fields that changed (typically `version`, `download_url`, `description`, `provides`, `requires`, `tags`, `updated_at`). Preserve `created_at` and `downloads`/`stars` from the existing entry.
+
+Use the existing entries as the format template. Required fields:
+
+```json
+{
+  "<id>": {
+    "name": "<name>",
+    "id": "<id>",
+    "description": "<description>",
+    "author": "<author>",
+    "version": "<version>",
+    "download_url": "<download_url>",
+    "repository": "<repository>",
+    "homepage": "<homepage>",
+    "documentation": "<documentation>",
+    "changelog": "<changelog>",
+    "license": "<license>",
+    "requires": {
+      "speckit_version": "<speckit_version>"
+    },
+    "provides": {
+      "commands": <N>,
+      "hooks": <N>
+    },
+    "tags": ["<tag1>", "<tag2>"],
+    "verified": false,
+    "downloads": 0,
+    "stars": 0,
+    "created_at": "<today>T00:00:00Z",
+    "updated_at": "<today>T00:00:00Z"
+  }
+}
+```
+
+If the extension has optional tool dependencies, add a `"tools"` array inside `"requires"`:
+
+```json
+"tools": [{ "name": "<tool>", "required": false }]
+```
+
+Also update the top-level `"updated_at"` timestamp in the catalog.
+
+After editing, **validate the JSON** by running:
+
+```bash
+python3 -c "import json; json.load(open('extensions/catalog.community.json')); print('Valid JSON')"
+```
+
+### 5. Add or update `docs/community/extensions.md` community extensions table
+
+**New extension:** Insert a new row into the `# Community Extensions` table in **alphabetical order** by extension name.
+
+**Update:** Find the existing row and update the description or other changed fields in-place.
+
+Determine the category and effect from the extension's behavior:
+
+```
+| <Name> | <Description> | `<category>` | <Effect> | [<repo-name>](<repository-url>) |
+```
+
+**Category** — one of: `docs`, `code`, `process`, `integration`, `visibility`
+**Effect** — `Read-only` (produces reports only) or `Read+Write` (modifies project files)
+
+### 6. Commit, push, and open PR
+
+Use `add-` for new extensions, `update-` for updates:
+
+```bash
+# New extension
+git checkout -b add-<extension-id>-extension
+
+# Update
+git checkout -b update-<extension-id>-extension
+```
+
+```bash
+git add extensions/catalog.community.json docs/community/extensions.md
+
+# New extension
+git commit -m "Add <Name> extension to community catalog
+
+Add <id> extension submitted by @<issue-author> to:
+- extensions/catalog.community.json (alphabetical order)
+- docs/community/extensions.md community extensions table
+
+Closes #<issue-number>"
+
+# Update
+git commit -m "Update <Name> extension to v<version>
+
+Update <id> extension submitted by @<issue-author>:
+- extensions/catalog.community.json (version, download_url, etc.)
+- docs/community/extensions.md community extensions table
+
+Closes #<issue-number>"
+
+git push origin <branch-name>
+```
+
+Then create a PR to `upstream` (`github/spec-kit`) with:
+- **Title:** `Add <Name> extension to community catalog` (or `Update <Name> extension to v<version>`)
+- **Body:** Include validation summary, `Closes #<issue-number>`, and `cc @<issue-author>`
+- **Head:** `<fork-owner>:<branch-name>`
+- **Base:** `main`
+
+## Common Pitfalls
+
+- **Alphabetical order matters** — entries must be sorted by ID in the JSON and by name in the docs table.
+- **Don't forget the catalog `updated_at`** — the top-level timestamp in `catalog.community.json` must be refreshed.
+- **Validate JSON after editing** — a trailing comma or missing brace will break the catalog.
+- **Use `Closes` not `Fixes`** — `Closes #N` is the correct keyword for submission issues.
+- **Match the proposed entry but verify** — the issue may include a proposed JSON block, but always validate field values against the actual repository state.
+- **Preserve `created_at` on updates** — keep the original `created_at` value; only change `updated_at`.
+- **Preserve `downloads` and `stars` on updates** — these reflect usage metrics and must not be reset.

+# Add Community Extension from Issue Submission
+
+You are a catalog maintenance agent for the Spec Kit project. Your job is to
+process community extension submission issues and create pull requests that add
+or update entries in the community extension catalog.
+
+## Triggering Conditions
+
+This workflow only triggers when the `extension-submission` label is added to an
+issue. Before processing, verify that the issue title starts with `[Extension]:`.
+If it does not, stop without commenting.
+
+## Step 1 — Read and Parse the Issue
+
+Read issue #${{ github.event.issue.number }}.
+
+Extract the following fields from the structured issue body (GitHub issue form
+fields):
+
+| Field | Issue Form ID | Required |
+|-------|--------------|----------|
+| Extension ID | `extension-id` | Yes |
+| Extension Name | `extension-name` | Yes |
+| Version | `version` | Yes |
+| Description | `description` | Yes |
+| Author | `author` | Yes |
+| Repository URL | `repository` | Yes |
+| Download URL | `download-url` | Yes |
+| License | `license` | Yes |
+| Homepage | `homepage` | No |
+| Documentation URL | `documentation` | No |
+| Changelog URL | `changelog` | No |
+| Required Spec Kit Version | `speckit-version` | Yes |
+| Required Tools | `required-tools` | No |
+| Number of Commands | `commands-count` | Yes |
+| Number of Hooks | `hooks-count` | No (default 0) |
+| Tags | `tags` | Yes |
+| Proposed Catalog Entry | `catalog-entry` | Yes |
+
+The issue body uses GitHub's issue form format. Each field appears under a
+heading matching the field label (e.g., `### Extension ID` followed by the
+value). Parse accordingly.
+
+## Step 2 — Validate the Submission
+
+Run **all** of the following validation checks. Collect all results before
+deciding pass/fail:
+
+### 2a. Extension ID format
+- Must match regex: `^[a-z][a-z0-9-]*$`
+- Must be lowercase with hyphens only
+
+### 2b. Version format
+- Must follow semver: `X.Y.Z` (digits only, no `v` prefix)
+
+### 2c. Repository validation
+- Fetch the repository URL — confirm it exists and is publicly accessible
+- Confirm the repository contains an `extension.yml` file
+- Confirm the repository contains a `README.md` file
+- Confirm the repository contains a `LICENSE` file
+
+### 2d. Release and download URL validation
+- The download URL should follow the pattern
+  `https://github.com/<owner>/<repo>/archive/refs/tags/v<version>.zip`
+  or
+  `https://github.com/<owner>/<repo>/releases/download/<tag>/<asset>.zip`
+- Verify a GitHub release exists matching the submitted version
+
+### 2e. Submission checklists
+- Confirm that all required checkboxes in the Testing Checklist and Submission
+  Requirements sections are checked (`[x]`)
+
+### Validation outcome
+
+If **any** validation fails:
+1. Add a comment on the issue listing each failed check with a clear explanation
+   of what's wrong and how to fix it
+2. Add the `validation-failed` label
+3. **Stop — do not proceed further**
+
+If all validations pass:
+1. Add the `validation-passed` label
+2. Continue to Step 3
+
+## Step 3 — Determine Add vs Update
+
+Search `extensions/catalog.community.json` for the extension ID.
+
+- **Not found** → this is a **new addition**
+- **Found** → this is an **update** — replace the existing entry in-place;
+  preserve `created_at`, `downloads`, and `stars` from the existing entry
+
+## Step 4 — Update `extensions/catalog.community.json`
+
+Edit `extensions/catalog.community.json` to add or update the extension entry.
+
+### For a new extension
+
+Insert the entry in **alphabetical order by extension ID** within the
+`"extensions"` object. Use this structure:
+
+```json
+{
+  "<id>": {
+    "name": "<name>",
+    "id": "<id>",
+    "description": "<description>",
+    "author": "<author>",
+    "version": "<version>",
+    "download_url": "<download_url>",
+    "repository": "<repository>",
+    "homepage": "<homepage or repository>",
+    "documentation": "<documentation or repository README>",
+    "changelog": "<changelog or empty string>",
+    "license": "<license>",
+    "requires": {
+      "speckit_version": "<speckit_version>"
+    },
+    "provides": {
+      "commands": <N>,
+      "hooks": <N>
+    },
+    "tags": ["<tag1>", "<tag2>"],
+    "verified": false,
+    "downloads": 0,
+    "stars": 0,
+    "created_at": "<today>T00:00:00Z",
+    "updated_at": "<today>T00:00:00Z"
+  }
+}
+```
+
+If the extension has optional tool dependencies, add a `"tools"` array inside
+`"requires"`:
+
+```json
+"tools": [{ "name": "<tool>", "required": false }]
+```
+
+### For an update
+
+Replace only the changed fields (typically `version`, `download_url`,
+`description`, `provides`, `requires`, `tags`, `updated_at`). **Preserve**
+`created_at`, `downloads`, and `stars` from the existing entry.
+
+### After editing
+
+Update the **top-level `"updated_at"` timestamp** in the catalog to today's date
+in ISO 8601 format.
+
+Validate the JSON by running:
+
+```bash
+python3 -c "import json; json.load(open('extensions/catalog.community.json')); print('Valid JSON')"
+```
+
+If validation fails, fix the JSON and re-validate before continuing.
+
+## Step 5 — Update `docs/community/extensions.md`
+
+Edit `docs/community/extensions.md` to add or update a row in the Community
+Extensions table.
+
+### For a new extension
+
+Insert a new row in **alphabetical order by extension name**:
+
+```
+| <Name> | <Description> | `<category>` | <Effect> | [<repo-name>](<repository-url>) |
+```
+
+Determine the category from the extension's behavior:
+- `docs` — reads, validates, or generates spec artifacts
+- `code` — reviews, validates, or modifies source code
+- `process` — orchestrates workflow across phases
+- `integration` — syncs with external platforms
+- `visibility` — reports on project health or progress
+
+Determine the effect:
+- `Read-only` — produces reports only
+- `Read+Write` — modifies project files
+
+### For an update
+
+Find the existing row and update any changed fields in-place.
+
+## Step 6 — Create Pull Request
+
+Create a pull request with the changes. Use this branch naming convention:
+
+- **New extension:** `add-<extension-id>-extension`
+- **Update:** `update-<extension-id>-extension`
+
+### Commit message
+
+For a new extension:
+```
+Add <Name> extension to community catalog
+
+Add <id> extension submitted by @<issue-author> to:
+- extensions/catalog.community.json (alphabetical order)
+- docs/community/extensions.md community extensions table
+
+Closes #<issue-number>
+```
+
+For an update:
+```
+Update <Name> extension to v<version>
+
+Update <id> extension submitted by @<issue-author>:
+- extensions/catalog.community.json (version, download_url, etc.)
+- docs/community/extensions.md community extensions table
+
+Closes #<issue-number>
+```
+
+### PR description
+
+Include:
+- A summary of what changed
+- Validation results (all checks passed)
+- `Closes #${{ github.event.issue.number }}`
+- `cc @<issue-author>` — mention the submitter
+
+## Important Rules
+
+- **Alphabetical order matters** — entries must be sorted by ID in the JSON and
+  by name in the docs table
+- **Always validate JSON** after editing — a trailing comma or missing brace
+  will break the catalog
+- **Use `Closes` not `Fixes`** — `Closes #N` is the correct keyword for
+  submission issues
+- **Match the proposed entry but verify** — the issue may include a proposed
+  JSON block, but always validate field values against the actual repository
+  state rather than blindly trusting the submitter's JSON
+- **Preserve `created_at` on updates** — keep the original value; only update
+  `updated_at`
+- **Preserve `downloads` and `stars` on updates** — these reflect usage metrics
+  and must not be reset
+- **Do not modify any other files** — only `extensions/catalog.community.json`
+  and `docs/community/extensions.md`

+- Must be lowercase with hyphens only
+
+### 2b. Version format
+- Must follow semver: `X.Y.Z` (digits only, no `v` prefix)
+
+### 2c. Repository validation
+- Fetch the repository URL — confirm it exists and is publicly accessible
+- Confirm the repository contains a `preset.yml` file
+- Confirm the repository contains a `README.md` file
+- Confirm the repository contains a `LICENSE` file
+
+### 2d. Release and download URL validation
+- The download URL should follow the pattern
+  `https://github.com/<owner>/<repo>/archive/refs/tags/v<version>.zip`
+  or
+  `https://github.com/<owner>/<repo>/releases/download/<tag>/<asset>.zip`
+- Verify a GitHub release exists matching the submitted version
+
+### 2e. Submission checklists
+- Confirm that all required checkboxes in the Testing Checklist and Submission
+  Requirements sections are checked (`[x]`)
+
+### Validation outcome
+
+If **any** validation fails:
+1. Add a comment on the issue listing each failed check with a clear explanation
+   of what's wrong and how to fix it
+2. Add the `validation-failed` label
+3. **Stop — do not proceed further**
+
+If all validations pass:
+1. Add the `validation-passed` label
+2. Continue to Step 3
+
+## Step 3 — Determine Add vs Update
+
+Search `presets/catalog.community.json` for the preset ID.
+
+- **Not found** → this is a **new addition**
+- **Found** → this is an **update** — replace the existing entry in-place;
+  preserve `created_at` from the existing entry
+
+## Step 4 — Update `presets/catalog.community.json`
+
+Edit `presets/catalog.community.json` to add or update the preset entry.
+
+### For a new preset
+
+Insert the entry in **alphabetical order by preset ID** within the
+`"presets"` object. Use this structure:
+
+```json
+{
+  "<id>": {
+    "name": "<name>",
+    "id": "<id>",
+    "version": "<version>",
+    "description": "<description>",
+    "author": "<author>",
+    "repository": "<repository>",
+    "download_url": "<download_url>",
+    "homepage": "<homepage or repository>",
+    "documentation": "<documentation or repository README>",
+    "license": "<license>",
+    "requires": {
+      "speckit_version": "<speckit_version>"
+    },
+    "provides": {
+      "templates": <N>,
+      "commands": <N>
+    },
+    "tags": ["<tag1>", "<tag2>"],
+    "created_at": "<today>T00:00:00Z",
+    "updated_at": "<today>T00:00:00Z"
+  }
+}
+```
+
+If the preset has required extensions, add an `"extensions"` array inside
+`"requires"`:
+
+```json
+"requires": {
+  "speckit_version": "<speckit_version>",
+  "extensions": ["<extension-id>"]
+}
+```
+
+If the preset provides scripts, add `"scripts": <N>` inside `"provides"`.
+
+### For an update
+
+Replace only the changed fields (typically `version`, `download_url`,
+`description`, `provides`, `requires`, `tags`, `updated_at`). **Preserve**
+`created_at` from the existing entry.
+
+### Counting templates and commands
+
+Parse the "Templates Provided" and "Commands Provided" issue fields:
+- Count the number of list items (lines starting with `-`)
+- If the field says "None", the count is 0
+
+### After editing
+
+Update the **top-level `"updated_at"` timestamp** in the catalog to today's date
+in ISO 8601 format.
+
+Validate the JSON by running:
+
+```bash
+python3 -c "import json; json.load(open('presets/catalog.community.json')); print('Valid JSON')"
+```
+
+If validation fails, fix the JSON and re-validate before continuing.
+
+## Step 5 — Update `docs/community/presets.md`
+
+Edit `docs/community/presets.md` to add or update a row in the Community
+Presets table.
+
+### For a new preset
+
+Insert a new row in **alphabetical order by preset name**:
+
+```
+| <Name> | <Description> | <N> templates, <N> commands | <Requires> | [<repo-name>](<repository-url>) |
+```
+
+For the Requires column:
+- Use `—` if no extensions are required
+- List required extension names if any (e.g., `AIDE extension`)
+
+If the preset provides scripts, include them: `<N> templates, <N> commands, <N> scripts`
+
+### For an update
+
+Find the existing row and update any changed fields in-place.
+
+## Step 6 — Create Pull Request
+
+Create a pull request with the changes. Use this branch naming convention:
+
+- **New preset:** `add-<preset-id>-preset`
+- **Update:** `update-<preset-id>-preset`
+
+### Commit message
+
+For a new preset:
+```
+Add <Name> preset to community catalog
+
+Add <id> preset submitted by @<issue-author> to:
+- presets/catalog.community.json (alphabetical order)
+- docs/community/presets.md community presets table
+
+Closes #<issue-number>
+```
+
+For an update:
+```
+Update <Name> preset to v<version>
+
+Update <id> preset submitted by @<issue-author>:
+- presets/catalog.community.json (version, download_url, etc.)
+- docs/community/presets.md community presets table
+
+Closes #<issue-number>
+```
+
+### PR description
+
+Include:
+- A summary of what changed
+- Validation results (all checks passed)
+- `Closes #${{ github.event.issue.number }}`
+- `cc @<issue-author>` — mention the submitter
+
+## Important Rules
+
+- **Alphabetical order matters** — entries must be sorted by ID in the JSON and
+  by name in the docs table
+- **Always validate JSON** after editing — a trailing comma or missing brace
+  will break the catalog
+- **Use `Closes` not `Fixes`** — `Closes #N` is the correct keyword for
+  submission issues
+- **Preserve `created_at` on updates** — keep the original value; only update
+  `updated_at`
+- **Do not modify any other files** — only `presets/catalog.community.json`
+  and `docs/community/presets.md`

-Create two thin wrapper scripts in `src/specify_cli/integrations/<package_dir>/scripts/` that delegate to the shared context-update scripts. Each is ~25 lines of boilerplate.
+Set `context_file` on the integration class. The base integration setup creates or updates the managed Spec Kit section in that file, and uninstall removes the managed section when appropriate.
 
-> **Note on `<package_dir>` vs `<key>`:** `<package_dir>` is the Python-safe directory name for your integration — it matches `<key>` exactly when the key contains no hyphens (e.g., key `"gemini"` → `gemini/`), but uses underscores when it does (e.g., key `"kiro-cli"` → `kiro_cli/`). The `IntegrationBase.key` class attribute always retains the original hyphenated value (e.g., `key = "kiro-cli"`), since that is what the CLI and registry use.
+The managed section is owned by the bundled `agent-context` extension (`extensions/agent-context/`). All configuration flows through the extension's own config file at `.specify/extensions/agent-context/agent-context-config.yml`:

-Replace `<key>` with your integration key and `<Agent Name>` / `<context_file>` with the appropriate values.
-
-You must also add the agent to the shared context-update scripts so the shared dispatcher recognises the new key:
-
-- **`scripts/bash/update-agent-context.sh`** — add a file-path variable and a case in `update_specific_agent()`.
-- **`scripts/powershell/update-agent-context.ps1`** — add a file-path variable, add the new key to the `AgentType` parameter's `[ValidateSet(...)]`, add a switch case in `Update-SpecificAgent`, and add an entry in `Update-AllExistingAgents`.
+Only add custom setup logic when the agent needs non-standard behavior. Integrations no longer require per-agent thin wrapper scripts or shared context-update dispatcher scripts — the `agent-context` extension is fully generic.

+## Branch Naming Convention
+
+Branches follow one of two patterns depending on whether an issue exists:
+
+```
+<type>/<number>-<short-slug>   # when an issue is created first
+<type>/<short-slug>            # when no issue exists (PR-only changes)
+```
+
+When an issue exists, include its number immediately after the prefix — this is what makes branches traceable. For small or self-contained changes that go straight to a PR without a tracking issue, omit the number.
+
+| Prefix | When to use | Example |
+|---|---|---|
+| `feat/` | New features | `feat/2342-workflow-cli-alignment` |
+| `fix/` | Bug fixes | `fix/2653-paths-only-validation` |
+| `docs/` | Documentation changes | `docs/2677-branch-naming-convention`, `docs/update-landing-stats` |
+| `community/` | Community catalog additions | `community/2492-add-mde-extension` |
+| `chore/` | Maintenance, tooling, CI | `chore/2366-editorconfig` |
+
+**Rules:**
+
+1. Include the issue number when one exists — this is what makes branches traceable
+2. Use kebab-case for the slug
+3. Keep the slug short — enough to identify the work without looking up the issue
+
+---
 
 ## Common Pitfalls
 
 1. **Using shorthand keys for CLI-based integrations**: For CLI-based integrations (`requires_cli: True`), the `key` must match the executable name (e.g., `"cursor-agent"` not `"cursor"`). `shutil.which(key)` is used for CLI tool checks — mismatches require special-case mappings. IDE-based integrations (`requires_cli: False`) are not subject to this constraint.
-2. **Forgetting update scripts**: Both bash and PowerShell thin wrappers and the shared context-update scripts must be updated.
+2. **Forgetting context configuration**: The bundled `agent-context` extension reads from `.specify/extensions/agent-context/agent-context-config.yml`. New integrations only need to set `context_file` on the class — markers and dispatcher scripts are managed centrally.
 3. **Incorrect `requires_cli` value**: Set to `True` only for agents that have a CLI tool; set to `False` for IDE-based agents.
 4. **Wrong argument format**: Use `$ARGUMENTS` for Markdown agents, `{{args}}` for TOML agents.
 5. **Skipping registration**: The import and `_register()` call in `_register_builtins()` must both be added.

+### Branch naming
+
+We recommend naming branches as `<type>/<number>-<short-slug>`, where `<number>` is the issue or PR number (whichever comes first) and `<type>` is one of:
+
+| Prefix | When to use | Example |
+|---|---|---|
+| `feat/` | New features | `feat/2342-workflow-cli-alignment` |
+| `fix/` | Bug fixes | `fix/2653-paths-only-validation` |
+| `docs/` | Documentation changes | `docs/2677-branch-naming-convention` |
+| `community/` | Community catalog additions | `community/2492-add-mde-extension` |
+| `chore/` | Maintenance, tooling, CI | `chore/2366-editorconfig` |
+
+Including the issue or PR number makes branches traceable — especially useful since the project uses squash merges and `git branch --merged` won't detect merged branches. If you start with a PR (no issue), use the PR number once it's assigned.

 ### 1. Install Specify CLI
 
-Choose your preferred installation method:
-
-> **Important:** The only official, maintained packages for Spec Kit are published from this GitHub repository. Any packages with the same name on PyPI are **not** affiliated with this project and are not maintained by the Spec Kit maintainers. Always install directly from GitHub as shown below.
-
-#### Option 1: Persistent Installation (Recommended)
-
-Install once and use everywhere. Pin a specific release tag for stability (check [Releases](https://github.com/github/spec-kit/releases) for the latest):
+Requires **[uv](https://docs.astral.sh/uv/)** ([install uv](./docs/install/uv.md)). Replace `vX.Y.Z` with the latest tag from [Releases](https://github.com/github/spec-kit/releases):
 
 ```bash
-# Install a specific stable release (recommended — replace vX.Y.Z with the latest tag)
 uv tool install specify-cli --from git+https://github.com/github/spec-kit.git@vX.Y.Z
-
-# Or install latest from main (may include unreleased changes)
-uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
 ```
 
-Then verify the correct version is installed:
+See the [Installation Guide](./docs/installation.md) for alternative methods, verification, upgrade, and troubleshooting.
+
+### 2. Initialize a project
 
 ```bash
-specify version
+specify init my-project --integration copilot
+cd my-project
 ```
 
-And use the tool directly:
+### 3. Establish project principles
 
-```bash
-# Create new project
-specify init <PROJECT_NAME>
-
-# Or initialize in existing project
-specify init . --ai copilot
-# or
-specify init --here --ai copilot
-
-# Check installed tools
-specify check
-```
-
-To upgrade Specify, see the [Upgrade Guide](./docs/upgrade.md) for detailed instructions. Quick upgrade:
-
-```bash
-uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git@vX.Y.Z
-```
-
-#### Option 2: One-time Usage
-
-Run directly without installing:
-
-```bash
-# Create new project (pinned to a stable release — replace vX.Y.Z with the latest tag)
-uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <PROJECT_NAME>
-
-# Or initialize in existing project
-uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init . --ai copilot
-# or
-uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init --here --ai copilot
-```
-
-**Benefits of persistent installation:**
-
-- Tool stays installed and available in PATH
-- No need to create shell aliases
-- Better tool management with `uv tool list`, `uv tool upgrade`, `uv tool uninstall`
-- Cleaner shell configuration
-
-#### Option 3: Enterprise / Air-Gapped Installation
-
-If your environment blocks access to PyPI or GitHub, see the [Enterprise / Air-Gapped Installation](./docs/installation.md#enterprise--air-gapped-installation) guide for step-by-step instructions on using `pip download` to create portable, OS-specific wheel bundles on a connected machine.

-
-- **[Greenfield .NET CLI tool](https://github.com/mnriem/spec-kit-dotnet-cli-demo)** — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
-
-- **[Greenfield Spring Boot + React platform](https://github.com/mnriem/spec-kit-spring-react-demo)** — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
-
-- **[Brownfield ASP.NET CMS extension](https://github.com/mnriem/spec-kit-aspnet-brownfield-demo)** — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
-
-- **[Brownfield Java runtime extension](https://github.com/mnriem/spec-kit-java-brownfield-demo)** — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.
-
-- **[Brownfield Go / React dashboard demo](https://github.com/mnriem/spec-kit-go-brownfield-demo)** — Demonstrates spec-kit driven entirely from the **terminal using GitHub Copilot CLI**. Extends NASA's open-source Hermes ground support system (Go) with a lightweight React-based web telemetry dashboard, showing that the full constitution → specify → plan → tasks → implement workflow works from the terminal.
-
-- **[Greenfield Spring Boot MVC with a custom preset](https://github.com/mnriem/spec-kit-pirate-speak-preset-demo)** — Builds a Spring Boot MVC application from scratch using a custom pirate-speak preset, demonstrating how presets can reshape the entire spec-kit experience: specifications become "Voyage Manifests," plans become "Battle Plans," and tasks become "Crew Assignments" — all generated in full pirate vernacular without changing any tooling.
-
-- **[Greenfield Spring Boot + React with a custom extension](https://github.com/mnriem/spec-kit-aide-extension-demo)** — Walks through the **AIDE extension**, a community extension that adds an alternative spec-driven workflow to spec-kit with high-level specs (vision) and low-level specs (work items) organized in a 7-step iterative lifecycle: vision → roadmap → progress tracking → work queue → work items → execution → feedback loops. Uses a family trading platform (Spring Boot 4, React 19, PostgreSQL, Docker Compose) as the scenario to illustrate how the extension mechanism lets you plug in a different style of spec-driven development without changing any core tooling — truly utilizing the "Kit" in Spec Kit.

+# Community Walkthroughs
+
+> [!NOTE]
+> Community walkthroughs are independently created and maintained by their respective authors. They are **not reviewed, nor endorsed, nor supported by GitHub**. Review their content before following along and use at your own discretion.
+
+See Spec-Driven Development in action across different scenarios with these community-contributed walkthroughs:
+
+- **[Greenfield .NET CLI tool](https://github.com/mnriem/spec-kit-dotnet-cli-demo)** — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
+
+- **[Greenfield Spring Boot + React platform](https://github.com/mnriem/spec-kit-spring-react-demo)** — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
+
+- **[Brownfield ASP.NET CMS extension](https://github.com/mnriem/spec-kit-aspnet-brownfield-demo)** — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
+
+- **[Brownfield Java runtime extension](https://github.com/mnriem/spec-kit-java-brownfield-demo)** — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.
+
+- **[Brownfield Go / React dashboard demo](https://github.com/mnriem/spec-kit-go-brownfield-demo)** — Demonstrates spec-kit driven entirely from the **terminal using GitHub Copilot CLI**. Extends NASA's open-source Hermes ground support system (Go) with a lightweight React-based web telemetry dashboard, showing that the full constitution → specify → plan → tasks → implement workflow works from the terminal.
+
+- **[Greenfield Spring Boot MVC with a custom preset](https://github.com/mnriem/spec-kit-pirate-speak-preset-demo)** — Builds a Spring Boot MVC application from scratch using a custom pirate-speak preset, demonstrating how presets can reshape the entire spec-kit experience: specifications become "Voyage Manifests," plans become "Battle Plans," and tasks become "Crew Assignments" — all generated in full pirate vernacular without changing any tooling.
+
+- **[Greenfield Spring Boot + React with a custom extension](https://github.com/mnriem/spec-kit-aide-extension-demo)** — Walks through the **AIDE extension**, a community extension that adds an alternative spec-driven workflow to spec-kit with high-level specs (vision) and low-level specs (work items) organized in a 7-step iterative lifecycle: vision → roadmap → progress tracking → work queue → work items → execution → feedback loops. Uses a family trading platform (Spring Boot 4, React 19, PostgreSQL, Docker Compose) as the scenario to illustrate how the extension mechanism lets you plug in a different style of spec-driven development without changing any core tooling — truly utilizing the "Kit" in Spec Kit.

+# What is Spec-Driven Development?
+
+Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them.
+
+## Core Philosophy
+
+Spec-Driven Development is a structured process that emphasizes:
+
+- **Intent-driven development** where specifications define the "*what*" before the "*how*"
+- **Rich specification creation** using guardrails and organizational principles
+- **Multi-step refinement** rather than one-shot code generation from prompts
+- **Heavy reliance** on advanced AI model capabilities for specification interpretation
+
+## Development Phases
+
+| Phase | Focus | Key Activities |
+|-------|-------|----------------|
+| **0-to-1 Development** ("Greenfield") | Generate from scratch | <ul><li>Start with high-level requirements</li><li>Generate specifications</li><li>Plan implementation steps</li><li>Build production-ready applications</li></ul> |
+| **Creative Exploration** | Parallel implementations | <ul><li>Explore diverse solutions</li><li>Support multiple technology stacks & architectures</li><li>Experiment with UX patterns</li></ul> |
+| **Iterative Enhancement** ("Brownfield") | Brownfield modernization | <ul><li>Add features iteratively</li><li>Modernize legacy systems</li><li>Adapt processes</li></ul> |
+
+## Experimental Goals
+
+Our research and experimentation focus on:
+
+### Technology Independence
+
+- Create applications using diverse technology stacks
+- Validate the hypothesis that Spec-Driven Development is a process not tied to specific technologies, programming languages, or frameworks
+
+### Enterprise Constraints
+
+- Demonstrate mission-critical application development
+- Incorporate organizational constraints (cloud providers, tech stacks, engineering practices)
+- Support enterprise design systems and compliance requirements
+
+### User-Centric Development
+
+- Build applications for different user cohorts and preferences
+- Support various development approaches (from vibe-coding to AI-native development)
+
+### Creative & Iterative Processes
+
+- Validate the concept of parallel implementation exploration
+- Provide robust iterative feature development workflows
+- Extend processes to handle upgrades and modernization tasks

+Spec Kit is a toolkit for [Spec-Driven Development](concepts/sdd.md) (SDD), a methodology that puts specifications at the center of AI-assisted software development. Instead of jumping straight to code, you describe *what* to build, refine it through structured phases, and let your AI coding agent implement it.

+# Enterprise / Air-Gapped Installation
+
+If your environment blocks access to PyPI or GitHub, you can create a portable wheel bundle on a connected machine and transfer it to the air-gapped target.
+
+## Step 1: Build the wheel on a connected machine
+
+> **Important:** `pip download` resolves platform-specific wheels (e.g., PyYAML includes native extensions). You must run this step on a machine with the **same OS and Python version** as the air-gapped target. If you need to support multiple platforms, repeat this step on each target OS (Linux, macOS, Windows) and Python version.
+
+```bash
+# Clone the repository
+git clone https://github.com/github/spec-kit.git
+cd spec-kit
+
+# Build the wheel
+pip install build
+python -m build --wheel --outdir dist/
+
+# Download the wheel and all its runtime dependencies
+pip download -d dist/ dist/specify_cli-*.whl
+```
+
+## Step 2: Transfer the `dist/` directory
+
+Copy the entire `dist/` directory (which contains the `specify-cli` wheel and all dependency wheels) to the target machine via USB, network share, or other approved transfer method.
+
+## Step 3: Install on the air-gapped machine
+
+```bash
+pip install --no-index --find-links=./dist specify-cli
+```
+
+## Step 4: Initialize a project
+
+No network access is required — bundled assets are used by default:
+
+```bash
+specify init my-project --integration copilot
+```
+
+> **Note:** Python 3.11+ is required.
+
+> **Windows note:** Offline scaffolding requires PowerShell 7+ (`pwsh`), not Windows PowerShell 5.x (`powershell.exe`). Install from https://aka.ms/powershell.
+
+## Git Credential Manager on Linux
+
+If you're having issues with Git authentication on Linux, you can install Git Credential Manager:
+
+```bash
+#!/usr/bin/env bash
+set -e
+echo "Downloading Git Credential Manager v2.6.1..."
+wget https://github.com/git-ecosystem/git-credential-manager/releases/download/v2.6.1/gcm-linux_amd64.2.6.1.deb

+# One-time Usage (uvx)
+
+If you want to try Spec Kit without installing it permanently, use `uvx` to run it directly. This downloads the tool into a temporary environment that is discarded after the command finishes.
+
+> [!NOTE]
+> The commands below require **[uv](https://docs.astral.sh/uv/)**. If you see `command not found: uvx`, [install uv first](uv.md).
+
+## Run Specify CLI
+
+```bash
+# Create a new project (latest from main)
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME>
+
+# Or target a specific release (replace vX.Y.Z with a tag from Releases)
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <PROJECT_NAME>

+
+# Or use the --here flag
+uvx --from git+https://github.com/github/spec-kit.git specify init --here --integration copilot
+```
+
+## When to use persistent installation instead
+
+If you plan to use Spec Kit regularly, a persistent installation is recommended:
+
+- Tool stays installed and available in PATH
+- No re-download on every invocation
+- Better tool management with `uv tool list`, `uv tool upgrade`, `uv tool uninstall`

+# Installing uv
+
+[uv](https://docs.astral.sh/uv/) is a fast Python package manager by [Astral](https://astral.sh/). Spec Kit uses `uv` (via `uvx` or `uv tool install`) to run the `specify` CLI without polluting your global Python environment.
+
+> [!NOTE]
+> **Already have uv?** Run `uv --version` to confirm it is installed, then head back to the [Installation Guide](../installation.md).
+
+## Installation
+
+### macOS and Linux — Standalone Installer
+
+The quickest way to install uv on macOS or Linux is the official shell script:
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+After the script finishes, follow any instructions printed by the installer to add uv to your `PATH`, then open a new terminal.
+
+### Windows — Standalone Installer
+
+Run the following in **Command Prompt or PowerShell**:
+
+```powershell
+powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+After the script finishes, open a new terminal so the `uv` binary is on your `PATH`.
+
+### macOS — Homebrew
+
+```bash
+brew install uv
+```
+
+### Windows — WinGet
+
+```powershell
+winget install --id=astral-sh.uv -e
+```
+
+### Windows — Scoop
+
+```powershell
+scoop install uv
+```
+
+## Verification
+
+Confirm that uv is installed and on your `PATH`:
+
+```bash
+uv --version
+```
+
+You should see output similar to `uv 0.x.y (...)`.
+
+## Further Reading
+
+For advanced options (self-update, proxy settings, uninstall, etc.) see the official [uv installation docs](https://docs.astral.sh/uv/getting-started/installation/).

 ## Troubleshooting
 
 ### Enterprise / Air-Gapped Installation
 
-If your environment blocks access to PyPI (you see 403 errors when running `uv tool install` or `pip install`), you can create a portable wheel bundle on a connected machine and transfer it to the air-gapped target.
-
-**Step 1: Build the wheel on a connected machine (same OS and Python version as the target)**
-
-```bash
-# Clone the repository
-git clone https://github.com/github/spec-kit.git
-cd spec-kit
-
-# Build the wheel
-pip install build
-python -m build --wheel --outdir dist/
-
-# Download the wheel and all its runtime dependencies
-pip download -d dist/ dist/specify_cli-*.whl
-```
-
-> **Important:** `pip download` resolves platform-specific wheels (e.g., PyYAML includes native extensions). You must run this step on a machine with the **same OS and Python version** as the air-gapped target. If you need to support multiple platforms, repeat this step on each target OS (Linux, macOS, Windows) and Python version.
-
-**Step 2: Transfer the `dist/` directory to the air-gapped machine**
-
-Copy the entire `dist/` directory (which contains the `specify-cli` wheel and all dependency wheels) to the target machine via USB, network share, or other approved transfer method.
-
-**Step 3: Install on the air-gapped machine**
-
-```bash
-pip install --no-index --find-links=./dist specify-cli
-```
-
-**Step 4: Initialize a project (no network required)**
-
-```bash
-# Initialize a project — no GitHub access needed
-specify init my-project --ai claude --offline
-```
-
-The `--offline` flag tells the CLI to use the templates, commands, and scripts bundled inside the wheel instead of downloading from GitHub.
-
-> **Deprecation notice:** Starting with v0.6.0, `specify init` will use bundled assets by default and the `--offline` flag will be removed. The GitHub download path will be retired because bundled assets eliminate the need for network access, avoid proxy/firewall issues, and guarantee that templates always match the installed CLI version. No action will be needed — `specify init` will simply work without network access out of the box.

-> **Note:** Python 3.11+ is required.
-
-> **Windows note:** Offline scaffolding requires PowerShell 7+ (`pwsh`), not Windows PowerShell 5.x (`powershell.exe`). Install from https://aka.ms/powershell.

+## Recommended Workflow
 
 > [!TIP]
 > **Context Awareness**: Spec Kit commands automatically detect the active feature based on your current Git branch (e.g., `001-feature-name`). To switch between different specifications, simply switch Git branches.
 
+After installing Spec Kit and defining your project constitution, quick experiments can use the lean feature path: `/speckit.specify` -> `/speckit.plan` -> `/speckit.tasks` -> `/speckit.implement`. For production features or any work with meaningful ambiguity, treat `/speckit.clarify`, `/speckit.checklist`, and `/speckit.analyze` as regular quality gates:

You can repeat `/speckit.analyze` after implementation as an extra review, but keep the first analysis before `/speckit.implement` so gaps are caught while the plan and tasks can still be adjusted.

+# Authentication
+
+Specify CLI uses **opt-in authentication** for HTTP requests to catalog
+sources, extension downloads, and release checks.  No credentials are
+sent unless you explicitly configure them.
+
+## Configuration
+
+Create `~/.specify/auth.json` to enable authentication:
+
+```json
+{
+  "providers": [
+    {
+      "hosts": ["github.com", "api.github.com", "raw.githubusercontent.com", "codeload.github.com"],
+      "provider": "github",
+      "auth": "bearer",
+      "token_env": "GH_TOKEN"
+    }
+  ]
+}
+```
+
+> **Security:** Restrict the file to owner-only access:
+> ```bash
+> chmod 600 ~/.specify/auth.json
+> ```
+
+Without this file, all HTTP requests are unauthenticated.
+
+## Fields
+
+Each entry in the `providers` array has the following fields:
+
+| Field | Required | Description |
+|---|---|---|
+| `hosts` | Yes | Array of hostnames this entry applies to. Supports exact hostnames, or a leading `*.` wildcard for subdomains only (for example, `*.visualstudio.com`). `*.visualstudio.com` matches `foo.visualstudio.com`, but not `visualstudio.com`. Other glob patterns such as `*github.com` or `gith?b.com` are not supported. |
+| `provider` | Yes | Built-in provider key: `github` or `azure-devops`. |
+| `auth` | Yes | Auth scheme (see below). |
+| `token` | No | Token value (inline). Use `token_env` instead when possible. |
+| `token_env` | No | Environment variable name to read the token from. |
+
+For `azure-ad` auth, additional fields are required:
+
+| Field | Required | Description |
+|---|---|---|
+| `tenant_id` | Yes | Azure AD tenant ID. |
+| `client_id` | Yes | Service principal client ID. |
+| `client_secret_env` | Yes | Environment variable containing the client secret. |
+
+Either `token` or `token_env` must be set for `bearer` and `basic-pat` schemes.
+
+## Providers and auth schemes
+
+### GitHub (`github`)
+
+| Scheme | Header | Use for |
+|---|---|---|
+| `bearer` | `Authorization: Bearer <token>` | PATs, fine-grained PATs, OAuth tokens, GitHub App tokens |
+
+**Example — PAT via environment variable:**
+
+```json
+{
+  "hosts": ["github.com", "api.github.com", "raw.githubusercontent.com", "codeload.github.com"],
+  "provider": "github",
+  "auth": "bearer",
+  "token_env": "GH_TOKEN"
+}
+```
+
+### Azure DevOps (`azure-devops`)
+
+| Scheme | Header | Use for |
+|---|---|---|
+| `basic-pat` | `Authorization: Basic base64(:<PAT>)` | Personal Access Tokens |
+| `bearer` | `Authorization: Bearer <token>` | Pre-acquired OAuth / Azure AD tokens |
+| `azure-cli` | `Authorization: Bearer <token>` | Token acquired via `az account get-access-token` |
+| `azure-ad` | `Authorization: Bearer <token>` | Token acquired via OAuth2 client credentials flow |
+
+**Example — PAT via environment variable:**
+
+```json
+{
+  "hosts": ["dev.azure.com"],
+  "provider": "azure-devops",
+  "auth": "basic-pat",
+  "token_env": "AZURE_DEVOPS_PAT"
+}
+```
+
+**Example — Azure CLI (interactive login):**
+
+```json
+{
+  "hosts": ["dev.azure.com"],
+  "provider": "azure-devops",
+  "auth": "azure-cli"
+}
+```
+
+Requires `az login` to have been run beforehand.
+
+**Example — Azure AD service principal (CI/automation):**
+
+```json
+{
+  "hosts": ["dev.azure.com"],
+  "provider": "azure-devops",
+  "auth": "azure-ad",
+  "tenant_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
+  "client_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
+  "client_secret_env": "AZURE_CLIENT_SECRET"
+}
+```
+
+## Multiple entries
+
+You can configure multiple entries for different hosts or organizations:
+
+```json
+{
+  "providers": [
+    {
+      "hosts": ["github.com", "api.github.com", "raw.githubusercontent.com", "codeload.github.com"],
+      "provider": "github",
+      "auth": "bearer",
+      "token_env": "GH_TOKEN"
+    },
+    {
+      "hosts": ["dev.azure.com"],
+      "provider": "azure-devops",
+      "auth": "basic-pat",
+      "token_env": "AZURE_DEVOPS_PAT"
+    }
+  ]
+}
+```
+
+## How it works
+
+1. For each outbound HTTP request, the URL hostname is matched against
+   the `hosts` patterns in `auth.json`.
+2. If a match is found, the corresponding provider resolves the token
+   and attaches the appropriate `Authorization` header.
+3. If the request receives a 401 or 403, the next matching entry is tried.
+4. After all matching entries are exhausted, an unauthenticated request
+   is attempted as a final fallback.
+5. On redirects, the `Authorization` header is stripped if the redirect
+   target leaves the entry's declared hosts — preventing credential
+   leakage to CDNs or third-party services.
+
+## Template
+
+A reference `auth.json` with GitHub pre-configured:
+
+```json
+{
+  "providers": [
+    {
+      "hosts": [
+        "github.com",
+        "api.github.com",
+        "raw.githubusercontent.com",
+        "codeload.github.com"
+      ],
+      "provider": "github",
+      "auth": "bearer",
+      "token_env": "GH_TOKEN"
+    }
+  ]
+}
+```
+
+To use it:
+
+```bash
+mkdir -p ~/.specify
+# Copy the JSON above into ~/.specify/auth.json
+chmod 600 ~/.specify/auth.json
+```

+If the target integration is not already installed, equivalent to running `uninstall` followed by `install` in a single step.

If the target integration is already installed, `switch` only changes the default integration, like `use`; in this mode, `--force` controls whether managed shared templates are overwritten while the default changes. `--integration-options` is rejected for already-installed targets because changing integration options requires reinstalling managed files; run `upgrade <key> --integration-options ...` first, then `use <key>`.

 ## FAQ
 
-### Can I use multiple integrations at the same time?
+### Can I install multiple integrations in the same project?
 
-No. Only one AI coding agent integration can be installed per project. Use `specify integration switch <key>` to change to a different AI coding agent.
+Yes, but it is intended for team portability rather than the default workflow. Multiple integrations are allowed automatically only when the installed integration and the new integration are declared multi-install safe by Spec Kit. For other combinations, pass `--force` to acknowledge that multiple agents may see unrelated agent-specific instructions or commands.
+
+Spec Kit tracks one default integration in `.specify/integration.json` with `default_integration`, all installed integrations with `installed_integrations`, per-integration runtime settings with `integration_settings`, and a dedicated `integration_state_schema` for future state migrations. The legacy `integration` field remains as an alias for the default integration.
+
+### Which integrations are multi-install safe?
+
+An integration is multi-install safe when it uses isolated agent directories, a dedicated context file that does not collide with another safe integration, stable command invocation settings, and a separate install manifest. Shared Spec Kit templates remain aligned to the single default integration.
+
+The currently declared multi-install safe integrations are:
+
+| Key | Isolation |
+| --- | --------- |
+| `auggie` | `.augment/commands`, `.augment/rules/specify-rules.md` |
+| `claude` | `.claude/skills`, `CLAUDE.md` |
+| `codebuddy` | `.codebuddy/commands`, `CODEBUDDY.md` |
+| `codex` | `.agents/skills`, `AGENTS.md` |
+| `cursor-agent` | `.cursor/skills`, `.cursor/rules/specify-rules.mdc` |

+| `kilocode` | `.kilocode/workflows`, `.kilocode/rules/specify-rules.md` |
+| `kimi` | `.kimi/skills`, `KIMI.md` |
+| `qodercli` | `.qoder/commands`, `QODER.md` |
+| `qwen` | `.qwen/commands`, `QWEN.md` |
+| `roo` | `.roo/commands`, `.roo/rules/specify-rules.md` |
+| `shai` | `.shai/commands`, `SHAI.md` |
+| `tabnine` | `.tabnine/agent/commands`, `TABNINE.md` |
+| `trae` | `.trae/skills`, `.trae/rules/project_rules.md` |
+| `windsurf` | `.windsurf/workflows`, `.windsurf/rules/specify-rules.md` |
+
+Integrations that share a context file or command directory with another integration, require dynamic install paths such as `--commands-dir`, or merge shared tool settings are not declared safe by default. They can still be installed alongside another integration with `--force`.

 ### When should I use `upgrade` vs `switch`?
 
-Use `upgrade` when you've upgraded Spec Kit and want to refresh the same integration's templates. Use `switch` when you want to change to a different AI coding agent.
+Use `upgrade` when you've upgraded Spec Kit and want to refresh an installed integration's managed files. Use `switch` when you want to replace the current default with another integration; if the target is already installed, `switch` behaves like `use`.

+# Coding Agent Context Extension
+
+This bundled extension manages the **coding agent context/instruction file** (e.g. `CLAUDE.md`, `.github/copilot-instructions.md`, `AGENTS.md`, `GEMINI.md`, …) for the active integration.
+
+It owns the lifecycle of the managed section delimited by the configurable start/end markers (defaults: `<!-- SPECKIT START -->` / `<!-- SPECKIT END -->`).
+
+## Why an extension?
+
+Not every Spec Kit user wants Spec Kit to write into the coding agent's context file. Extracting this behavior into a dedicated extension lets users:
+
+- **Opt out** entirely with `specify extension disable agent-context` — Spec Kit will then never create or modify the agent context file.
+- **Customize the markers** by editing `.specify/extensions/agent-context/agent-context-config.yml` — both the Python layer and the bundled scripts honor the same `context_markers` value.
+- **Refresh on demand** with `/speckit.agent-context.update`, or automatically through the hooks declared in `extension.yml` (`after_specify`, `after_plan`).
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `speckit.agent-context.update` | Refresh the managed section in the agent context file with the current plan path. |
+
+## Configuration
+
+All configuration flows through the extension's own config file at
+`.specify/extensions/agent-context/agent-context-config.yml`:
+
+```yaml
+# Path to the coding agent context file managed by this extension
+context_file: CLAUDE.md
+
+# Delimiters for the managed Spec Kit section
+context_markers:
+  start: "<!-- SPECKIT START -->"
+  end: "<!-- SPECKIT END -->"
+```
+
+- `context_file` — the project-relative path to the coding agent context file, written by `specify init` and `specify integration install`.
+- `context_markers.start` / `.end` — the delimiters around the managed section. Edit these to use custom markers.
+
+## Requirements
+
+The bundled update scripts require **Python 3** with **PyYAML** for YAML/upsert processing (PowerShell can also use `ConvertFrom-Yaml` when available).
+
+PyYAML ships with the `specify` CLI and is normally available via the same `python3` interpreter. If a hook reports *"PyYAML is required … not available in the current Python environment"*, it means the system `python3` differs from the one used to install Spec Kit. To resolve, run:
+
+```bash
+pip install pyyaml
+# or target the specific interpreter Spec Kit uses:
+/path/to/speckit-python -m pip install pyyaml
+```
+
+## Disable
+
+```bash
+specify extension disable agent-context
+```
+
+When disabled, Spec Kit skips context file creation, updates, and removal (the gates are inside `upsert_context_section()` and `remove_context_section()`).

+
+# Update Coding Agent Context
+
+Refresh the managed Spec Kit section inside the active coding agent's context/instruction file (e.g. `CLAUDE.md`, `.github/copilot-instructions.md`, `AGENTS.md`).
+
+## Behavior
+
+The script reads the agent-context extension config at
+`.specify/extensions/agent-context/agent-context-config.yml` to discover:
+
+- `context_file` — the path of the coding agent context file to manage.
+- `context_markers.start` / `.end` — the delimiters surrounding the managed section. Defaults to `<!-- SPECKIT START -->` and `<!-- SPECKIT END -->` when the field is missing.
+
+It then creates, replaces, or appends the managed block so that the section points at the most recent plan path when one can be discovered (`specs/<feature>/plan.md`).
+
+If `context_file` is empty or the file cannot be located, the command reports nothing to do and exits successfully.
+
+## Execution
+
+- **Bash**: `.specify/extensions/agent-context/scripts/bash/update-agent-context.sh [plan_path]`
+- **PowerShell**: `.specify/extensions/agent-context/scripts/powershell/update-agent-context.ps1 [plan_path]`
+
+When `plan_path` is omitted, the script auto-detects the most recently modified `specs/*/plan.md`.

+# Spec Kit - April 2026 Newsletter
+
+This edition covers Spec Kit activity in April 2026. Seventeen releases shipped (v0.4.4 through v0.8.3), delivering a full integration plugin architecture, a workflow engine, preset composition strategies, an integration catalog, and comprehensive documentation. The community extension catalog tripled from 26 to 83 entries, community presets grew from 2 to 12, and Spec Kit appeared on the Thoughtworks Technology Radar. A summary is in the table below, followed by details.

+| Seventeen releases shipped with major features: integration plugin architecture, workflow engine, preset composition, integration catalog, bundled lean preset, documentation site, and academic citation support. Three new agents added (Forgecode, Goose, Devin for Terminal). The repo grew from ~82k to **92,038 stars**. [\[github.com\]](https://github.com/github/spec-kit/releases) | Thoughtworks Technology Radar placed Spec Kit in the "Assess" ring. Community catalog grew from 26 to **83 extensions** and from 2 to **12 presets**. 12 substantive external articles published. XB Software documented a real legacy project. Fabián Silva shipped the Caramelo VS Code extension. | Matt Rickard argued for "smaller specs, harder checks." Will Torber's three-framework comparison recommended OpenSpec for most teams. The "Spec Layer" debate emerged: specs as constraint surfaces for AI agents. Spec Kit leads in breadth and portability; competitors differentiate on drift detection and orchestration depth. |
+
+***
+
+> **Important:** April's release pace outran external coverage. Most analyses published during the month (Rickard on April 1, Thoughtworks Radar on April 15, XB Software on April 17, Torber on April 23) were evaluating versions that predated the workflow engine (v0.7.0), integration catalog (v0.7.2), preset composition (v0.8.0), and catalog discovery CLI (v0.8.3). The ceremony and flexibility concerns they raised are precisely what these features address — the lean preset, pluggable workflows, composable presets, and community extensions like Conduct, MAQA, and Fleet Orchestrator already deliver alternative workflows beyond the default SDD process. We look forward to seeing how upcoming reviews account for these capabilities.
+
+## Spec Kit Project Updates
+
+### Releases Overview
+
+**v0.4.4** (April 1) delivered the first stage of the **integration plugin architecture** — base classes, a manifest system, and a registry that replaced the hard-coded agent scaffolding. It also added the Product Forge, Superpowers Bridge, MAQA suite (7 extensions), Spec Kit Onboard, and Plan Review Gate to the community catalog, fixed Claude Code CLI detection for npm-local installs, and added `--allow-existing-branch` to `create-new-feature`. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.4.4)
+
+**v0.4.5** (April 2) completed the integration migration in five stages: standard markdown integrations for 19 agents, TOML integrations (Gemini, Tabnine), skills and generic integrations, and removal of the legacy scaffold path. It also installed Claude Code as native skills, added a `--dry-run` flag for `create-new-feature`, support for 4+ digit feature branch numbers, the Fix Findings extension, and five lifecycle extensions to the community catalog. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.4.5)
+
+**v0.5.0** (April 2) was a significant packaging change: **template zip bundles were removed from releases**, with the CLI itself now handling all scaffolding. This ensured CLI and templates stay in sync. It also introduced `DEVELOPMENT.md` for contributor onboarding. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.5.0)
+
+**v0.5.1** (April 8) was a large patch release. It added the **bundled Git extension** (stages 1 and 2) with hooks on all core commands and `GIT_BRANCH_NAME` override support, **Forgecode** agent support, and the `specify integration` subcommand for post-init integration management. Argument hints were added to Claude Code commands. Numerous community extensions joined the catalog (Confluence, Canon, Spec Diagram, Branch Convention, Spec Refine, FixIt, Optimize, Security Review) along with presets (explicit-task-dependencies, toc-navigation, VS Code Ask Questions). Bug fixes included pinning typer≥0.24.0/click≥8.2.1 to fix an import crash, BSD-portable sed escaping, Trae agent fix, TOML frontmatter stripping, and preventing ambiguous TOML closing quotes. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.5.1)
+
+**v0.6.0** (April 9) rewrote **AGENTS.md for the new integration architecture**, added the SpecKit Companion to Community Friends, and brought Bugfix Workflow, Worktree Isolation, and MemoryLint to the community catalog. A new multi-repo-branching preset arrived. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.6.0)
+
+**v0.6.1** (April 10) added the **bundled lean preset** with a minimal workflow command set — a lighter-weight alternative to the full SDD ceremony. It also migrated **Cursor** from `.cursor/commands` to `.cursor/skills` and added Brownfield Bootstrap, CI Guard, SpecTest, PR Bridge, TinySpec, and Status Report to the community catalog. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.6.1)
+
+**v0.6.2** (April 13) added **Goose AI agent** support (YAML-based recipe format), the GitHub Issues Integration extension, and the What-if Analysis extension. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.6.2)
+
+**v0.7.0** (April 14) delivered the **workflow engine with catalog system**, enabling pluggable, multi-step workflow definitions. It added SFSpeckit (Salesforce SDD), the Worktrees extension, optional single-segment branch prefix for gitflow compatibility, and the claude-ask-questions and fiction-book-writing presets. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.7.0)
+
+**v0.7.1** (April 15) deprecated the `--ai` flag in favor of `--integration` on `specify init`, added Windows to the CI test matrix, fixed Claude skill chaining for hook execution, merged TESTING.md into CONTRIBUTING.md, and added the Agent Assign and Architect Preview extensions. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.7.1)
+
+**v0.7.2** (April 16) delivered the **integration catalog** for discovery, versioning, and community distribution of agent integrations. It also produced a major **documentation overhaul**: reference pages for core commands, extensions, presets, workflows, and integrations were added to `docs/reference/`, and the README CLI section was simplified. The Issues extension and Catalog CI extension joined the community catalog. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.7.2)
+
+**v0.7.3** (April 17) replaced shell-based context updates with a **marker-based upsert** mechanism, eliminating accidental context file bloat. It added a **Community Friends page** to the docs site, the Spec Scope and Blueprint extensions, and a Claude Code/Copilot CLI plugin marketplace reference in the README. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.7.3)
+
+**v0.7.4** (April 21) added **CITATION.cff and .zenodo.json** for academic citation support. It introduced Ripple (side-effect detection), Spec Validate, Version Guard, Spec Reference Loader, and Memory Loader extensions. A fix stripped UTF-8 BOM from agent context files, and the Antigravity (agy) agent layout was migrated to `.agents/` with `--skills` deprecated. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.7.4)
+
+**v0.7.5** (April 22) added `specify self check` and `self upgrade` stubs, the **preset wrap strategy** (completing the composition trifecta alongside prepend and append), the Red Team adversarial review extension, the Wireframe extension, and a **directory traversal security fix** in command write paths. Skill placeholder resolution was expanded to all SKILL.md agents. Community content (walkthroughs and presets) was moved from the README to the docs site. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.7.5)
+
+**v0.8.0** (April 23) delivered **preset composition strategies** (prepend, append, wrap) for templates, commands, and scripts — enabling presets to layer content around existing artifacts. It also added Copilot `--integration-options="--skills"` for skills-based scaffolding, `pipx` as an alternative installation method, and the Memory MD extension. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.8.0)
+
+**v0.8.1** (April 24) fixed `/speckit.plan` on custom git branches via `.specify/feature.json`, migrated the **Mistral Vibe** integration to SkillsIntegration, added the **Screenwriting** and **Jira** presets, and resolved command reference formats per integration type (dot vs. hyphen notation). [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.8.1)
+
+**v0.8.2** (April 28) introduced **GITHUB_TOKEN/GH_TOKEN authentication** for private catalog and extension downloads, deprecated the `--no-git` flag (removal gated at v0.10.0), replaced all deprecated `--ai` references with `--integration` in documentation, and added MarkItDown Document Converter, Microsoft 365 Integration, Spec Orchestrator, and the Fiction Book Writing v1.7 preset with RAG (Chroma DB) offline semantic search. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.8.2)
+
+**v0.8.3** (April 29) closed the month with **catalog discovery CLI commands** (search, info, catalog list/add/remove), support for **Devin for Terminal** as a skills-based integration, a fix for the opencode command dispatch, and the OWASP LLM Threat Model, iSAQB Architecture Governance, and Work IQ extensions. A fix was also added to the upgrade hint to prevent users from accidentally installing a PyPI squat package. [\[github.com\]](https://github.com/github/spec-kit/releases/tag/v0.8.3)
+
+### Architecture & Infrastructure Highlights
+
+The most significant architectural change in April was the **integration plugin architecture** (v0.4.4–v0.4.5), which replaced hard-coded agent scaffolding with a registry of self-describing integration classes. Each agent is now a self-contained subpackage under `src/specify_cli/integrations/<key>/` with base classes for Markdown, TOML, YAML, and Skills formats. This six-stage migration touched all 28 supported agents and laid the groundwork for the integration catalog (v0.7.2) and community-distributed integrations.
+
+The **workflow engine** (v0.7.0) introduced a catalog-based system for pluggable, multi-step workflow definitions — moving beyond the fixed seven-step SDD sequence.
+
+**Preset composition strategies** (v0.7.5/v0.8.0) completed the preset system with prepend, append, and wrap modes. Presets can now layer content around existing templates, commands, and scripts rather than only replacing them.
+
+The **marker-based context upsert** (v0.7.3) replaced fragile shell-based sed operations for updating agent context files, eliminating a class of bugs around context bloat and encoding issues.
+
+**Template zip bundles were removed** (v0.5.0), coupling the CLI and templates into a single distributable artifact.
+
+### Bug Fixes and Security
+
+The most critical fix was **blocking directory traversal in command write paths** (#2229, v0.7.5), which prevented a potential path traversal vulnerability in the CommandRegistrar. Other security-adjacent fixes included hardening against a **PyPI squat package** in upgrade hints (v0.8.3) and adding **GITHUB_TOKEN authentication** for private catalog downloads (v0.8.2).
+
+Notable bug fixes: typer/click import crash (v0.5.1), BSD-portable sed escaping (v0.5.1), UTF-8 BOM stripping from context files (v0.7.4), CRLF warning suppression in PowerShell auto-commit (v0.7.3), Claude skill chaining for hooks (v0.7.1), TOML ambiguous closing quotes (v0.5.1), and custom branch support for `/speckit.plan` (v0.8.1). [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### The Extension & Preset Ecosystem
+
+The community extension catalog **tripled** during April, growing from 26 to **83 entries**. 59 new extensions were added and 2 were removed (Cognitive Squad and Understanding, whose repositories were no longer available). Community presets grew from 2 to **12 entries**, with 10 new presets added.
+
+Notable new extensions by category:
+
+- **Project management**: GitHub Issues Integration (Fatima367, aaronrsun), Spec Orchestrator (Quratulain-bilal), Agent Assign (xuyang), Status Report (Open-Agent-Tools)
+- **Quality & security**: Red Team adversarial review (Ash Brener), Security Review (DyanGalih), Ripple side-effect detection (chordpli), Spec Validate (Ahmed Eltayeb), CI Guard (Quratulain-bilal), OWASP LLM Threat Model (NaviaSamal)
+- **Multi-agent & orchestration**: MAQA suite with 7 extensions covering multi-agent QA, Jira, Azure DevOps, GitHub Projects, Linear, and Trello integrations (GenieRobot), Product Forge (VaiYav)
+- **Spec lifecycle**: Spec Refine (Quratulain-bilal), Bugfix Workflow (Quratulain-bilal), Fix Findings (Quratulain-bilal), Brownfield Bootstrap (Quratulain-bilal), TinySpec (Quratulain-bilal)
+- **Developer experience**: Blueprint code review (chordpli), Confluence (aaronrsun), MarkItDown Document Converter (BenBtg), Microsoft 365 Integration (BenBtg), Memory MD (DyanGalih), Memory Loader (KevinBrown5280), MemoryLint (RbBtSn0w)
+- **Domain-specific**: SFSpeckit for Salesforce (Sumanth Yanamala), iSAQB Architecture Governance preset (Thorsten Hindermann), Canon baseline-driven workflows (Maxim Stupakov)
+- **Creative**: Fiction Book Writing preset v1.7 with RAG/Chroma DB support (Andreas Daumann), Screenwriting preset (Andreas Daumann)
+
+Notable contributor **Quratulain-bilal** contributed 15 extensions during the month, spanning spec lifecycle, workflow management, and CI/CD integration. **GenieRobot** contributed the 7-extension MAQA suite. **BenBtg** contributed both MarkItDown and Microsoft 365 integrations. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### Documentation Overhaul
+
+April saw a comprehensive documentation effort. Reference pages for **core commands, extensions, presets, workflows, and integrations** were created under `docs/reference/`. Community content — **walkthroughs, presets, and a Community Friends page** — was moved from the README to `docs/community/`, reducing README length while improving discoverability. The deprecated `--ai` flag references were replaced with `--integration` across all documentation. TESTING.md was merged into CONTRIBUTING.md, and `DEVELOPMENT.md` was introduced for contributor onboarding. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+## Community & Content
+
+### Thoughtworks Technology Radar
+
+On **April 15**, the **Thoughtworks Technology Radar Volume 34** placed GitHub Spec Kit in the **"Assess" ring** under Languages & Frameworks. The blip noted that teams report value in brownfield projects, that the constitution captures project scope and architecture, but flagged potential **instruction bloat, context rot, and verbose markdown output** as concerns to watch. This is the first appearance of any SDD-specific tool on the Radar. [\[thoughtworks.com\]](https://www.thoughtworks.com/radar/languages-and-frameworks/github-spec-kit)
+
+### Developer Articles and Blog Posts
+
+April produced 12 substantive external articles (plus one excluded as AI-generated SEO spam).
+
+**Matt Rickard** published *"The Spec Layer: Why Spec-Driven Development (SDD) Works"* on April 1. His thesis: specs reduce execution freedom for AI agents, functioning as constraint surfaces. He compared Spec Kit, Kiro, OpenSpec, Tessl, Intent, and Symphony, and advocated for **"smaller specs, harder checks, less guessing."** [\[blog.matt-rickard.com\]](https://blog.matt-rickard.com/p/the-spec-layer)
+
+**Fabián Silva** published *"I Built a Visual Spec-Driven Development Extension for VS Code That Works With Any LLM"* on April 3 on DEV Community. His **Caramelo** VS Code extension adds a visual UI, approval gates, Jira integration, and multi-LLM support on top of Spec Kit's workflow, reading and writing the standard `specs/` directory. [\[dev.to\]](https://dev.to/fabian_silva_/i-built-a-visual-spec-driven-development-extension-for-vs-code-that-works-with-any-llm-36ok)
+
+**James M** published *"GitHub Spec Kit in 2026: SDD Goes Mainstream"* on April 4, calling the transition "from framework to platform" and highlighting Claude Code native skills, multi-agent support, and the massive ecosystem growth. [\[jamesm.blog\]](https://jamesm.blog/ai/github-spec-kit-2026-update/)

+
+### Community Friends and Tools
+
+The **SpecKit Companion** VS Code extension was added to the Community Friends section (v0.6.0). A community-maintained plugin for **Claude Code and GitHub Copilot CLI** that installs Spec Kit skills via the plugin marketplace was referenced in the README (v0.7.3). Fabián Silva's **Caramelo** VS Code extension demonstrated a visual UI approach to SDD. [\[github.com\]](https://github.com/github/spec-kit)
+
+## SDD Ecosystem & Industry Trends
+
+### The "Spec Layer" Debate
+
+Matt Rickard's "The Spec Layer" essay established a new framing for SDD: specifications as **constraint surfaces** that reduce execution freedom for AI agents. His comparison of six SDD tools argued for smaller, more focused specs with harder verification checks — a departure from comprehensive specification documents. This framing resonated across the community, with the Thoughtworks Radar entry and multiple comparison articles echoing the tension between spec depth and practical overhead.
+
+### Competitive Landscape
+
+**Will Torber's** three-framework comparison (Spec Kit, BMAD, OpenSpec) recommended **OpenSpec for most teams**, citing lower ceremony and better brownfield support. **Truong Phung** proposed combining Spec Kit with **Superpowers** (Jesse Vincent) for a "plan WHAT + control HOW" hybrid. These comparisons reflected a maturing market where practitioners combine tools rather than picking one.
+
+The **Thoughtworks Radar** placement validated SDD as a category worth tracking but flagged instruction bloat and context rot as open concerns — the same issues the Augment Code comparison raised in March. XB Software's field report confirmed these in practice: SDD adds value for complex legacy work but creates unnecessary overhead for small tasks.
+
+Spec Kit continued to lead in **GitHub popularity** (92k stars) and **agent breadth** (29 integrations). The market continued to differentiate along several axes: Spec Kit on portability and ecosystem breadth, Intent on living specs and drift detection, BMAD-METHOD on multi-agent orchestration, and OpenSpec on simplicity. [\[dev.to\]](https://dev.to/willtorber/spec-kit-vs-bmad-vs-openspec-choosing-an-sdd-framework-in-2026-d3j) [\[thoughtworks.com\]](https://www.thoughtworks.com/radar/languages-and-frameworks/github-spec-kit)
+
+## Roadmap
+
+Areas under discussion or in progress for future development:
+
+- **Spec lifecycle management** — context rot and spec drift remained the most cited concern across articles (Thoughtworks Radar, XB Software, Will Torber). The marker-based upsert (v0.7.3) addressed context file drift; spec-level drift detection remains an open area. The Reconcile and Archive extensions are community steps toward this. [\[thoughtworks.com\]](https://www.thoughtworks.com/radar/languages-and-frameworks/github-spec-kit)
+- **Workflow customization** — the workflow engine (v0.7.0) and preset composition strategies (v0.8.0) provide the foundation. Community presets for fiction writing, screenwriting, Jira tracking, and architecture governance demonstrate the breadth of possible workflows beyond standard SDD. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Catalog discovery and distribution** — the integration catalog (v0.7.2) and catalog discovery CLI (v0.8.3) bring `specify` closer to a package-manager experience for extensions, presets, and integrations. Private catalog authentication (v0.8.2) supports enterprise distribution. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Experience simplification** — the bundled lean preset (v0.6.1), `specify self check` (v0.7.5), and the deprecation of `--ai` in favor of `--integration` (v0.7.1) reflect ongoing work to reduce ceremony and improve the onboarding experience. Multiple external articles (Torber, XB Software) noted SDD overhead as a barrier. [\[dev.to\]](https://dev.to/willtorber/spec-kit-vs-bmad-vs-openspec-choosing-an-sdd-framework-in-2026-d3j)
+- **Cross-platform and enterprise** — Windows CI (v0.7.1), GITHUB_TOKEN authentication (v0.8.2), Salesforce-specific extensions, and the iSAQB architecture governance preset indicate growing enterprise adoption. [\[github.com\]](https://github.com/github/spec-kit)

+# Spec Kit - May 2026 Newsletter
+
+This edition covers Spec Kit activity in May 2026 — a month defined by three milestone 100s: **100,000+ stars**, **100+ community extensions**, and recognition as a **top-100 GitHub project**. Fourteen releases shipped (v0.8.4 through v0.8.17), delivering multi-agent install support, constitution governance enforcement, and continued architecture cleanup. The Open Source Friday livestream, a wave of multilingual coverage, and analyst recognition from The Futurum Group marked the project's transition from fast-moving experiment to established ecosystem. A summary is in the table below, followed by details.
+
+| **Spec Kit Core (May 2026)** | **Community & Content** | **SDD Ecosystem & Next** |
+| --- | --- | --- |
+| Fourteen releases shipped with key features: multi-install for concurrent agent integrations, constitution governance in implement, authentication provider registry, Hermes and Lingma agents, and a `__init__.py` decomposition series. The repo grew from ~92k to **106,951 stars**, crossing **100K** on May 21. [\[github.com\]](https://github.com/github/spec-kit/releases) | The community extension catalog crossed **100 entries** (now 105). Open Source Friday livestream drove a press wave: Visual Studio Magazine, DevOps.com, MarkTechPost, HackerNoon, and 25+ more articles — now tracked across multiple languages following an expanded discovery methodology. **217 contributors** now listed. | MarkTechPost called Spec Kit "the most community-adopted open-source option" for SDD. The Futurum Group's Mitch Ashley framed specs as "the unit of governance across agents and contributors." Truong Phung published a 61-min production playbook referencing Spec Kit. Competitors grew but differentiate on orchestration; Spec Kit leads in portability and community. |
+
+***
+
+> **A Month of 100s.** May 2026 was defined by three milestones that all share the same number. The community extension catalog crossed **100 entries** during the week of May 21, making Spec Kit a genuine platform with more capabilities in its ecosystem than in its core. The repository crossed **100,000 GitHub stars** on the same week. And with 107K stars at month's end, Spec Kit now ranks among the **top 100 most-starred projects on all of GitHub**. None of this would have happened without the community — the contributors, extension authors, preset builders, article writers, and practitioners who turned a spec-driven development experiment into an ecosystem. Thank you.
+
+## Spec Kit Project Updates
+
+### Releases Overview
+
+**v0.8.4–v0.8.7** (May 1–7) opened the month with four patch releases delivering the most-requested feature of the year: **multi-install support for concurrent AI agent integrations** (#2389), enabling multiple agents in a single project. This closed five long-standing issues dating back 228 days. The releases also added **constitution governance in `/speckit.implement`** (#2460), ensuring the implement phase now loads `constitution.md` to enforce governance during code generation. An **authentication provider registry** (#2393) added config-driven multi-platform auth. The **Lingma agent** joined the integration roster. Security hardening included pinning all remaining GitHub Actions to immutable SHAs (#2441) and URL scheme validation to prevent SSRF-style bugs (#2449). Seven new community extensions and six new governance-themed presets landed. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+**v0.8.8–v0.8.10** (May 8–14) shipped three releases focused on stability. **Version feature reporting** (#2548) improved upgrade visibility. Bug fixes addressed the Kiro CLI `$ARGUMENTS` placeholder (#1926, open 52 days), markdownlint-safe template metadata (#1343, open 147 days), and preset skill description precedence. The `__init__.py` decomposition series began with PRs 1–2/8, extracting `_console.py`, `_assets.py`, and `_utils.py`. Seven new extensions joined (Architecture Workflow, Agent Governance, BrownKit, Schedule, Reqnroll BDD, MDE, Changelog) along with two new presets (MDE, game-narrative-writing). The docs site received a major overhaul: the landing page was revamped with a four-pillar card layout, the install section was streamlined, and the community extensions table moved to the docs site. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+**v0.8.11–v0.8.13** (May 15–21) delivered three releases as the repo **crossed 100K stars**. **Agentic catalog submissions** (#2655) added AI-assisted workflows for community catalog contributions. A **high-assurance spec workflow** was documented (#2518). The while/do-while loop stale output bug (#2592) was caught and fixed same-day. **Integration auto mode** (#2421) now follows the project's initialized AI instead of hardcoding Copilot. The PowerShell UTF-8 BOM issue (#2280) was resolved. Four new extensions joined (Team Assign, Interactive HTML Preview, Time Machine, Superpowers Implementation Bridge), bringing the catalog to **103 entries** — crossing the 100 mark. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+**v0.8.14–v0.8.17** (May 22–28) closed the month with four releases. The **Hermes Agent** joined as a new integration target (#2651). Workflows gained a **`{{ context.run_id }}` template variable** (#2664). A new `SPECKIT_INTEGRATION_<KEY>_EXTRA_ARGS` environment variable (#2596) lets users pass extra flags to agent subprocesses. **Extension installs from URLs now prompt for confirmation** (#2745), a security improvement for URL-based installs. The spec quality checklist is now **re-validated after clarify updates the spec** (#2715). Token Budget, Product Spec, and Workflow Preset extensions joined the catalog, bringing it to **105 entries**. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### Architecture & Refactoring
+
+The most significant internal effort in May was the **`__init__.py` decomposition series**, progressing through PRs 1–4 of 8. This systematic extraction moved `_console.py`, `_assets.py`, `_utils.py`, `_version.py`, and the `commands/` package out of the monolithic init module, improving maintainability and contributor onboarding. The **ExtensionCatalog was migrated to the shared catalog stack base** (#2437), reducing duplicated catalog handling across extension, preset, and integration catalogs. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### Bug Fixes and Security
+
+Fourteen releases produced a strong cadence of fixes. Long-standing issues resolved include the Kiro CLI `$ARGUMENTS` placeholder (52 days), markdownlint template metadata line breaks (147 days), and the `--ai` flag for adding agent commands (136 days). The PowerShell UTF-8 BOM issue was fixed, preset skill rendering now correctly resolves `__SPECKIT_COMMAND_*__` refs (#2717), and a Windows gate-step crash was addressed (#2635).
+
+Security improvements included **URL-based extension install confirmation** (#2745), **pinning GitHub Actions to immutable SHAs** (#2441), **URL scheme validation** (#2449), and restricting community submission workflows to labeled events only (#2741). [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### The Extension & Preset Ecosystem
+
+The community extension catalog grew from 92 to **105 entries** during May, crossing the **100 mark** on May 21. Thirteen new extensions were added over the month. Community presets grew from 18 to **21 entries**, with three new presets added.
+
+Notable new extensions by category:
+
+- **Architecture & governance**: Architecture Workflow (bigsmartben), Agent Governance (bigben), Architecture Guard (DyanGalih), BrownKit (Maksim Shautsou)
+- **Cost & token management**: Cost Tracker (Quratulain-bilal), Token Analyzer (Chris Roberts), Token Budget (Tine Kondo)
+- **Agent orchestration**: Agent Orchestrator (pragya247), Multi-Model Review (formin)
+- **Project management**: Team Assign (tarunkumarbhati), Changelog (Quratulain-bilal)
+- **Cloud & enterprise**: Spec2Cloud for Azure (Azure Samples), .NET Framework to Modern .NET Migration (RogerBestMsft)
+- **API & lifecycle**: API Evolve (Quratulain-bilal), Product Spec (spec-kit-product contributors)
+- **Quality**: Schedule with CP-SAT solver (Julio César Franco Ardila), Reqnroll BDD (LoogaCY Studio), MDE (AI-MDE)
+- **Spec exploration**: Interactive HTML Preview (bigsmartben), Time Machine (te3yo)
+- **Cross-tool bridges**: Superpowers Implementation Bridge (lihan3238)
+
+New governance-themed presets dominated: a11y-governance, architecture-governance, security-governance, cross-platform-governance, agent-parity-governance, and Spec2Cloud preset. Creative presets included game-narrative-writing and MDE.
+
+The extension ecosystem also showed maturation through active maintenance. **Architecture Guard** progressed through four releases (v1.6.7 → v1.8.9), adding documentation quality improvements and governance features. **Memory MD** shipped multiple updates (v0.6.9 → v0.8.0), adding a `speckit.memory-md.log-finding` command. **Security Review** reached v1.4.5 with a new `speckit.security-review.log-finding` command. **Superpowers Implementation Bridge** evolved rapidly (v0.5.0 → v0.7.0). **Squad Bridge** updated to v1.3.0, **Fiction Book Writing** to v1.8.1, **Security Governance** to v0.4.0, and **MemoryLint** to v1.4.0. [\[github.com\]](https://github.github.io/spec-kit/community/extensions.html)
+
+### Documentation & Docs Site
+
+The docs site received its most significant update since launch. The **landing page was revamped** with a four-pillar card layout (#2531). The **install section was streamlined** (#2561). The **community extensions table** was moved from the README to the docs site (#2560), reducing README length while improving discoverability. **Community sections in the README** were consolidated (#2736). The **uv installation guide** was added with inline callouts (#2465). Landing page stats and branch naming conventions were updated (#2727). [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+## Community & Content
+
+### The Open Source Friday Livestream
+
+On **May 8**, the **GitHub Open Source Friday livestream** featured Spec Kit, hosted by Andrea Griffiths with lead maintainer Manfred Riem. The livestream demonstrated a full SDD workflow building a time-zone-aware command-line utility with GitHub Copilot in VS Code. Riem described AI agents as "a very capable intern and a very quick intern but it's still an intern nonetheless." He emphasized that "the spec is always the source of truth" and highlighted the community ecosystem, noting the project was "nearing the 100 mark" for extensions. The livestream drove significant press attention in the following days. [\[youtube.com\]](https://www.youtube.com/watch?v=2IArMAhkJcE)
+
+### Press and Industry Coverage
+
+May produced the broadest press coverage to date, with publications from the mainstream developer media covering Spec Kit for the first time.
+
+**Visual Studio Magazine** (David Ramel, May 12) published *"GitHub Spec Kit Takes Off as Antidote to Piecemeal 'Vibe Coding'"*, reporting on the Open Source Friday livestream and the growing ecosystem. The article noted Spec Kit's story is "no longer just that GitHub open sourced a spec-driven development toolkit last fall" but that "the toolkit is becoming a fast-moving ecosystem for teams trying to make AI-assisted development more structured, repeatable and traceable." [\[visualstudiomagazine.com\]](https://visualstudiomagazine.com/articles/2026/05/12/github-spec-kit-takes-off-as-antidote-to-piecemeal-vibe-coding.aspx)

+
+### Developer Articles and Blog Posts
+
+May produced a wave of independent coverage — well beyond any previous month. Starting this month, article discovery was expanded beyond English-centric search engines to include language-appropriate engines for 25+ languages, so the broader coverage partly reflects wider discovery rather than a sudden spike.
+
+Notable non-English coverage:
+
+- **Japanese**: テックオーシャン published a detailed experience report on *"Claude Code × Spec Kit"* on note.com, praising task decomposition accuracy while noting spec sync requires manual workarounds. [\[note.com\]](https://note.com/techocean_corp/n/nd2bd63106c16)

+## SDD Ecosystem & Industry Trends
+
+### The Analyst View
+
+The Futurum Group's **Mitch Ashley** provided the most significant analyst framing of SDD to date on DevOps.com: "GitHub's Spec Kit signals AI-assisted coding is shifting from prompts to durable, versioned specifications. Vendors are competing to own the artifact that governs intent across Copilot, Claude Code, and Gemini CLI." He warned that "verification at each checkpoint cannot be deferred to the agent producing it" — echoing the project's own emphasis on human oversight at phase boundaries. [\[devops.com\]](https://devops.com/githubs-spec-kit-puts-the-spec-back-in-software-development/)
+
+### The Production Playbook Pattern
+
+**Truong Phung's** 61-minute production playbook represented a new level of depth in community content. Rather than reviewing Spec Kit as a tool, Phung treated SDD as a given and built a comprehensive guide around the **Spec → Plan → Code → Verify loop**, with Spec Kit and Superpowers as the reference implementations. His seven opening truths — "the bottleneck moved from typing to thinking," "context engineering > prompt engineering," and "the PR is the unit of work, not the ticket" — capture the emerging practitioner consensus around structured AI development. [\[dev.to\]](https://dev.to/truongpx396/building-production-grade-fullstack-products-with-ai-coding-agents-a-practical-playbook-2idd)
+
+### Competitive Landscape
+
+The **MarkTechPost comparison** of nine SDD tools called Spec Kit "the most community-adopted open-source option," while positioning competitors along distinct axes: **Kiro** (integrated IDE with EARS-based specs and agent hooks), **BMAD-METHOD** (~48K stars, 12+ specialized agents), **GSD** (~64K stars, lean meta-prompting), **Augment Code** (context engine for 400K+ files, not a spec authoring tool), **OpenSpec** (~52K stars, change accountability and audit trails), and **Tessl** (spec registry with 10K+ library specs). [\[marktechpost.com\]](https://www.marktechpost.com/2026/05/08/9-best-ai-tools-for-spec-driven-development-in-2026-kiro-bmad-gsd-and-more-compare/)
+
+With 107K stars at month's end, Spec Kit is the **only spec-driven development tool in the top 100 most-starred repositories on GitHub** — none of the competitors above are close to the 100K threshold. The broader top-100 list includes AI-adjacent projects like agentic skills frameworks (obra/superpowers at 212K, anthropics/skills at 143K), agent harness tools, and LLM inference engines, but Spec Kit is the only one built around a spec-first development workflow. [\[github.com\]](https://github.com/search?q=stars%3A%3E100000&type=repositories&s=stars&o=desc)
+
+## Roadmap
+
+Areas under discussion or in progress for future development:
+
+- **CLI architecture cleanup** — the `__init__.py` decomposition (4/8 complete) continues toward a modular command structure. This internal cleanup improves contributor onboarding and test isolation. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Spec lifecycle management** — spec drift and context rot remain the most cited concern across articles (DevOps.com, DeployHQ, テックオーシャン). The clarify re-validation (#2715) and reconcile extensions are incremental steps; a more comprehensive solution is expected. [\[devops.com\]](https://devops.com/githubs-spec-kit-puts-the-spec-back-in-software-development/)
+- **Multi-agent workflows** — multi-install support (#2389) was the most-requested feature. The next frontier is orchestrating multiple agents across phases, a pattern the community's MAQA, Fleet, and Conduct extensions already explore. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Catalog maturity** — catalog discovery CLI (v0.8.3), agentic submissions (v0.8.13), and GITHUB_TOKEN auth (v0.8.2) are building toward a package-manager experience. As the catalog grows past 100 entries, curation and quality signals become critical. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Experience simplification** — the deployment gap (DeployHQ), ceremony overhead for small tasks (テックオーシャン, spec-coding.dev), and verbose output (Thoughtworks Radar) continue as open concerns. The lean preset, TinySpec extension, and workflow engine provide answers; discoverability of these options remains an opportunity. [\[deployhq.com\]](https://www.deployhq.com/blog/spec-kit-copilot-workspaces-deployment)
+- **Toward a stable release** — fourteen releases in one month reflects pre-1.0 momentum. The git extension default-off notice (#2432, gated at v0.10.0) and the `--no-git` deprecation (removal at v0.10.0) signal a path toward API stabilization.

+### Composition Strategies
+
+Templates, commands, and scripts support a `strategy` field that controls how a preset's content is combined with lower-priority content instead of fully replacing it:
+
+| Strategy | Description | Templates | Commands | Scripts |
+|----------|-------------|-----------|----------|---------|
+| `replace` (default) | Fully replaces lower-priority content | ✓ | ✓ | ✓ |
+| `prepend` | Places content before lower-priority content (separated by a blank line) | ✓ | ✓ | — |
+| `append` | Places content after lower-priority content (separated by a blank line) | ✓ | ✓ | — |
+| `wrap` | Content contains `{CORE_TEMPLATE}` (templates/commands) or `$CORE_SCRIPT` (scripts) placeholder replaced with lower-priority content | ✓ | ✓ | ✓ |
+
+Composition is recursive — multiple composing presets chain. The `PresetResolver.resolve_content()` method walks the full priority stack bottom-up and applies each layer's strategy.
+
+Content resolution functions for composition:
+- **Python**: `PresetResolver.resolve_content()` in `src/specify_cli/presets.py` (templates, commands, and scripts)
+- **Bash**: `resolve_template_content()` in `scripts/bash/common.sh` (templates only; command/script composition is handled by the Python resolver)
+- **PowerShell**: `Resolve-TemplateContent` in `scripts/powershell/common.ps1` (templates only; command/script composition is handled by the Python resolver)

 ## Command Registration
 
 When a preset is installed with `type: "command"` entries, the `PresetManager` registers them into all detected agent directories using the shared `CommandRegistrar` from `src/specify_cli/agents.py`.

-Presets **override**, they don't merge. If two presets both provide `spec-template`, the one with the lowest priority number wins entirely.
+Presets **override by default**, they don't merge. If two presets both provide `spec-template` with the default `replace` strategy, the one with the lowest priority number wins entirely. However, presets can use **composition strategies** to augment rather than replace content.
+
+### Composition Strategies
+
+Presets can declare a `strategy` per template to control how content is combined. The `name` field identifies which template to compose with in the priority stack, while `file` points to the actual content file (which can differ from the convention path `templates/<name>.md`):
+
+```yaml
+provides:
+  templates:
+    - type: "template"
+      name: "spec-template"
+      file: "templates/spec-addendum.md"
+      strategy: "append"        # adds content after the core template
+```
+
+| Strategy | Description |
+|----------|-------------|
+| `replace` (default) | Fully replaces the lower-priority template |
+| `prepend` | Places content **before** the resolved lower-priority template, separated by a blank line |
+| `append` | Places content **after** the resolved lower-priority template, separated by a blank line |
+| `wrap` | Content contains `{CORE_TEMPLATE}` placeholder (or `$CORE_SCRIPT` for scripts) replaced with the lower-priority content |
+
+**Supported combinations:**
+
+| Type | `replace` | `prepend` | `append` | `wrap` |
+|------|-----------|-----------|----------|--------|
+| **template** | ✓ (default) | ✓ | ✓ | ✓ |
+| **command** | ✓ (default) | ✓ | ✓ | ✓ |
+| **script** | ✓ (default) | — | — | ✓ |
+
+Multiple composing presets chain recursively. For example, a security preset with `prepend` and a compliance preset with `append` will produce: security header + core content + compliance footer.
 
 ## Catalog Management
 
 Presets are discovered through catalogs. By default, Spec Kit uses the official and community catalogs:
 
 > [!NOTE]
-> Community presets are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do **not review, audit, endorse, or support the preset code itself**. Review preset source code before installation and use at your own discretion.

 The following enhancements are under consideration for future releases:
 
-- **Composition strategies** — Allow presets to declare a `strategy` per template instead of the default `replace`:
-
-  | Type | `replace` | `prepend` | `append` | `wrap` |
-  |------|-----------|-----------|----------|--------|
-  | **template** | ✓ (default) | ✓ | ✓ | ✓ |
-  | **command** | ✓ (default) | ✓ | ✓ | ✓ |
-  | **script** | ✓ (default) | — | — | ✓ |
-
-  For artifacts and commands (which are LLM directives), `wrap` would inject preset content before and after the core template using a `{CORE_TEMPLATE}` placeholder. For scripts, `wrap` would run custom logic before/after the core script via a `$CORE_SCRIPT` variable.
-- **Script overrides** — Enable presets to provide alternative versions of core scripts (e.g. `create-new-feature.sh`) for workflow customization. A `strategy: "wrap"` option could allow presets to run custom logic before/after the core script without fully replacing it.
+- **Structural merge strategies** — Parsing Markdown sections for per-section granularity (e.g., "replace only ## Security").
+- **Conflict detection** — `specify preset lint` / `specify preset doctor` for detecting composition conflicts.

+# Lean Workflow
+
+A minimal preset that strips the Spec Kit workflow down to its essentials — just the prompt, just the artifact.
+
+## When to Use
+
+Use Lean when you want the structured specify → plan → tasks → implement pipeline without the ceremony of the full templates. Each command produces a single focused Markdown file with no boilerplate sections to fill in.
+
+## Commands Included
+
+| Command | Output | Description |
+|---------|--------|-------------|
+| `speckit.specify` | `spec.md` | Create a specification from a feature description |
+| `speckit.plan` | `plan.md` | Create an implementation plan from the spec |
+| `speckit.tasks` | `tasks.md` | Create dependency-ordered tasks from spec and plan |
+| `speckit.implement` | *(code)* | Execute all tasks in order, marking progress |
+| `speckit.constitution` | `constitution.md` | Create or update the project constitution |
+
+## What It Replaces
+
+Lean overrides the five core workflow commands with self-contained prompts that produce each artifact directly — no separate template files involved. The result is a shorter, more direct workflow.
+
+## Installation
+
+```bash
+# Lean is a bundled preset — no download needed
+specify preset add lean
+```
+
+## Development
+
+```bash
+# Test from local directory
+specify preset add --dev ./presets/lean
+
+# Verify commands resolve
+specify preset resolve speckit.specify
+
+# Remove when done
+specify preset remove lean
+```
+
