Codex Game Studios v0.5.0

Codex Game Studios v0.5.0

v0.5.0 evaluates Codex runtime hook support and turns the project policy into a CI-backed check.

Highlights

• Added docs/hooks/runtime-hook-evaluation.md with the current hook decision, rationale, legacy hook mapping, and future adoption gate.
• Confirmed that Codex Game Studios does not bundle plugin runtime hooks in this release.
• Added tools/validate_hook_policy.py to enforce no hooks field in the plugin manifest and no plugin-root hooks/ directory.
• Wired hook policy validation into GitHub Actions.
• Bumped regenerated plugin metadata to 0.5.0.

Decision

Codex plugin hooks exist, but plugin-bundled hooks are off by default unless users enable [features].plugin_hooks = true. For this project template, safety checks should behave the same in a fresh clone and in CI. Therefore v0.5 keeps safety behavior explicit through scripts and skill instructions.

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\validate_hook_policy.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 #5 Track Codex hook schema and evaluate runtime hook support with a documented decision: do not wire runtime hooks yet; keep explicit validators as the stable safety layer.
