v1.3.0

What changed

• converted the repository to a Codex plugin-ready layout with bundled skills under skills/
• added .codex-plugin/plugin.json and repo-local plugin marketplace metadata for Codex installs
• restored and documented direct skill installation from the shared skills/ tree alongside plugin installation
• expanded repo validation and smoke coverage for plugin metadata and moved scaffold entrypoints
• documented the OpenAI-first, future-Claude multi-platform direction and added roadmap milestones for Claude skill and plugin support

Breaking changes

• repository layout changed from flat top-level skill directories to skills/<skill-name>/
• any old path references that assumed skill directories at repo root must be updated

Migration and upgrade notes

• for Codex plugin installs, use the repo marketplace flow via .agents/plugins/marketplace.json
• for direct skill installs, install from skills/ into standard .agents/skills locations
• plugin manifest version is now 1.3.0 to align with this tagged release

Verification performed

• uv run scripts/validate_repo_metadata.py
• uv run pytest
• temp-dir smoke coverage for FastAPI, FastMCP, and uv workspace scaffold entrypoints via the pytest smoke suite
