 ## 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.

+# 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 - 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).

+## 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)

+**HackerNoon** (Andrey Kucherenko, May 6) published *"The Spec-First Development Showdown"*, a hands-on comparison of Spec Kit, OpenSpec, BMAD, and Gangsta Agents. [\[hackernoon.com\]](https://hackernoon.com/the-spec-first-development-showdown-spec-kit-openspec-bmad-and-gangsta-agents-compared)
+
+### 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:
+

+## 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. [\[github.com\]](https://github.com/github/spec-kit/releases)
