Codex Pro Agent Skills

Niche, high-signal skills for professional Codex agents. The repo layout is intentionally small and direct: each skill lives under skills/<skill-name> and contains its own SKILL.md, optional agents/ metadata, and optional bundled resources.

Adding Skills

Use this shape for every new skill:

skills/<skill-name>/
├── SKILL.md
├── agents/
│   └── openai.yaml
└── references/

Keep SKILL.md compact and put detailed domain notes in references/ so Codex can load only the files needed for the current task.
