Consider extracting git-repo-agent into standalone repository

[laurigates]

Summary

git-repo-agent is a standalone Claude Agent SDK CLI tool that lives in this monorepo but is not a Claude Code plugin (not in marketplace.json or release-please). Extracting it into its own repo would:

• Enable clean uvx git-repo-agent and uv tool install git-repo-agent workflows
• Provide clearer separation of concerns
• Simplify independent versioning and release management

Current Coupling

The only coupling to this monorepo is compiler.py, which reads 35 SKILL.md files from 8 sibling plugins at runtime to build subagent prompts. The compiled output is 7 files totaling ~328KB.

Speculative Approach: Pre-compiled prompts with optional live compilation

Ship pre-compiled prompt files in the package. When running inside the monorepo (dev mode), compile fresh from SKILL.md sources. When installed standalone, read from the generated/ directory. The generated files are derived artifacts, not source duplication.

Why not alternatives

• Git submodule: uv/uvx does clone submodules (with absolute URLs), but it would pull in the entire claude-plugins monorepo — heavyweight for 328KB of derived content
• Separate PyPI package for prompts: over-engineered for 328KB of static markdown
• Runtime download: adds network dependency and failure modes to CLI startup

Key changes

1. Modify compiler.py — add fallback to read from generated/ when plugin sources aren't available:

   @lru_cache(maxsize=None)
   def get_compiled_prompt(subagent_name: str) -> str:
       skill_paths = SUBAGENT_SKILLS.get(subagent_name)
       if not skill_paths:
           return ""
   
       # Live compilation when running inside claude-plugins monorepo
       if _PLUGINS_ROOT.is_dir() and any(
           (_PLUGINS_ROOT / p).exists() for p in skill_paths
       ):
           return compile_subagent(subagent_name, skill_paths)
   
       # Standalone mode: read pre-compiled generated files
       generated = _MODULE_DIR / "generated" / f"{subagent_name}_skills.md"
       if generated.exists():
           return generated.read_text(encoding="utf-8")
   
       return ""

2. Create laurigates/git-repo-agent repo with contents of claude-plugins/git-repo-agent/ as root

3. Update pyproject.toml with license, readme, repository URL for PyPI publishing

4. Cross-repo prompt updates — GitHub Actions workflow in claude-plugins triggered on SKILL.md changes that opens a PR on the git-repo-agent repo with regenerated files:

   on:
     push:
       branches: [main]
       paths:
         - 'blueprint-plugin/skills/*/SKILL.md'
         - 'configure-plugin/skills/*/SKILL.md'
         - 'code-quality-plugin/skills/*/SKILL.md'
         - 'testing-plugin/skills/*/SKILL.md'
         - 'git-plugin/skills/*/SKILL.md'
         - 'github-actions-plugin/skills/*/SKILL.md'
         - 'kubernetes-plugin/skills/*/SKILL.md'

5. Clean up monorepo — replace git-repo-agent/ directory with a README pointing to the new repo, update references in codebase-attributes-plugin/README.md

Verification

• uv tool install . from the new repo should work without claude-plugins present
• compile_prompts.py --check should pass in both monorepo and standalone contexts
• Subagent behavior should be identical between monorepo and standalone installs
