Codex Game Studios v0.4.0

Codex Game Studios v0.4.0

v0.4.0 focuses on local plugin installation UX. Codex builds may expose repo-local plugin installation differently, so this release documents both the preferred marketplace path and the reliable path-based fallback.

Highlights

• Added docs/install/local-plugin.md with the expected marketplace, plugin manifest, and skill paths.
• Documented verification prompts for $cgs-help, $cgs-project-stage-detect, and starter workflows.
• Documented fallback prompts that call SKILL.md files by path when local plugin installation is unavailable.
• Added troubleshooting checks for repo-root selection, JSON parsing, manifest paths, stale discovery, and runtime hook expectations.
• Added tools/validate_plugin_install_docs.py and wired it into CI.

Validation

Run these from the repository root:

python tools\migrate_from_claude.py
python tools\prepare_v01.py
python tools\validate_cgs.py
python tools\validate_skills.py
python tools\validate_smoke_fixture.py
python tools\validate_transcripts.py
python tools\validate_plugin_install_docs.py
python tools\scan_legacy_tokens.py
python -m json.tool plugins\codex-game-studios\.codex-plugin\plugin.json
python -m json.tool .agents\plugins\marketplace.json

Roadmap Impact

This release closes the initial documentation scope for #3 Document local plugin install UX and fallback paths.

The hook schema tracking issue remains open until Codex plugin runtime hook behavior is stable enough to wire safely.
