chore: bump version to 0.8.13

* fix: while/do-while loop condition reads stale iteration-0 step output

After executing namespaced loop body steps, copy each iteration's
results back to the original unprefixed step key so that
evaluate_condition() sees the latest values instead of stale
iteration-0 data.

Fixes #2592

* address review: cross-platform tests, preserve iteration-0 history

- Rewrite shell scripts in tests to use Python via script files
  instead of POSIX syntax, so they pass on Windows CI.
- Snapshot iteration-0 nested-step results under a namespaced key
  (parent:child:0) before the first copy-back overwrite, preserving
  complete per-iteration history for debugging.

* address review: skip copy-back on paused/failed iterations

Move the status check before the copy-back so that partial results
from paused or failed nested steps (e.g., a gate awaiting input)
do not overwrite the unprefixed key. This preserves correct resume
behavior.

* address review: quote paths in test shell commands

Quote both the Python executable and script file paths in the
run: commands to handle spaces in paths on Windows.

* address review: execute loop body with original IDs

Instead of namespacing step IDs for execution and copying results
back, execute the loop body with original (unprefixed) step IDs so
results naturally land at the right keys.  Snapshot previous
iteration results to namespaced keys (parent:child:N) for history
only.

This fixes multi-step loop bodies where step B references step A's
output within the same iteration — previously step B would see
stale data until the copy-back ran after the entire iteration.

* address review: namespaced execution with per-step copy-back

Revert to namespaced step IDs for execution (preserving unique
log entries and state keys per iteration) but copy each step's
result back to the unprefixed key immediately after it completes.

This preserves backward compatibility (same namespaced key format,
same log IDs) while fixing both the condition evaluation bug and
inter-step references within multi-step loop bodies.

* address review: alias after status check, add multi-step body test

- Move per-step aliasing below the PAUSED/FAILED/ABORTED status
  check so partial results from incomplete steps are not aliased
  back to the unprefixed key.
- Add test_while_loop_multi_step_body_inter_step_refs to exercise
  a multi-step loop body where step B reads step A's output within
  the same iteration, verifying per-step aliasing works correctly.

Addresses feedback from @doquanghuy (items 2 & 4) and Copilot
review on commit 9d0a222.

* address review: stable fallback IDs, expression-based inter-step test

- Use enumerate() for stable fallback IDs when loop body steps lack
  an explicit id (step-0, step-1, etc. instead of always step-0).
- Rewrite multi-step body test so step B uses expression
  substitution ({{ steps.step-a.output.stdout }}) instead of
  reading the counter file directly, making it a true regression
  test for per-step aliasing.

DO NOT USE FOR: creating new extensions from scratch, or first-party extension work.'

+
+# 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 triggers on issue events. **Only process the issue if ALL of these
+conditions are met:**
+
+1. The issue has the `extension-submission` label
+2. The issue title starts with `[Extension]:`
+
+If the issue does not meet these conditions, add a brief comment explaining that
+this workflow only processes extension submission issues, then stop.
+
+## 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`

+    "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`

 ### 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):
-
-> [!NOTE]
-> The `uv tool install` commands below require **[uv](https://docs.astral.sh/uv/)** — a fast Python package manager. If you see `command not found: uv`, [install uv first](./docs/install/uv.md). The `pipx` alternative does not require uv.
+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
-
-# Alternative: using pipx (also works)
-pipx install git+https://github.com/github/spec-kit.git@vX.Y.Z
-pipx install 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:
-
-```bash
-# Create new project
-specify init <PROJECT_NAME>
-
-# Or initialize in existing project
-specify init . --integration copilot
-# or
-specify init --here --integration 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
-# pipx users: pipx install --force 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 . --integration copilot
-# or
-uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init --here --integration 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.

 ## 🧩 Community Extensions
 
+Community-contributed extensions add new commands, hooks, and capabilities to Spec Kit. See the full list on the [Community Extensions](https://github.github.io/spec-kit/community/extensions.html) page.
+
 > [!NOTE]
-> Community extensions are independently created and maintained by their respective authors. Maintainers only verify that catalog entries are complete and correctly formatted — they do **not review, audit, endorse, or support the extension code itself**. The Community Extensions website is also a third-party resource. Review extension source code before installation and use at your own discretion.

+# 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 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`
+

 ## 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 --integration claude
-```
-
-Bundled assets are used by default — no network access is required.
-
-> **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.
+If your environment blocks access to PyPI or GitHub, see the [Enterprise / Air-Gapped Installation](install/air-gapped.md) guide for step-by-step instructions on creating portable wheel bundles.
 
 ### 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
-echo "Installing Git Credential Manager..."
-sudo dpkg -i gcm-linux_amd64.2.6.1.deb
-echo "Configuring Git to use GCM..."
-git config --global credential.helper manager
-echo "Cleaning up..."
-rm gcm-linux_amd64.2.6.1.deb
-```
+If you're having issues with Git authentication on Linux, see the [Air-Gapped Installation guide](install/air-gapped.md#git-credential-manager-on-linux) for Git Credential Manager setup instructions.

-## The 6-Step Process
+## 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:
+
+```text
+/speckit.constitution -> /speckit.specify -> /speckit.clarify -> /speckit.checklist -> /speckit.plan -> /speckit.tasks -> /speckit.analyze -> /speckit.implement
+```
+
+Use `/speckit.clarify` to reduce requirement ambiguity before planning, `/speckit.checklist` to validate requirements quality before planning, and `/speckit.analyze` to check spec/plan/task consistency before implementation starts. 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.
