Codex Skills Collection

Agent Skills extend Codex with specialized workflows (open SKILL.md). July 2026 refresh: official openai/skills catalog, Figma/CI/Sentry/Notion picks, and modern .agents/skills paths.

Install skills for Codex

Prefer `.agents/skills/` (shared open standard). Use `$skill-installer <name>` from the bundled openai/skills system skill, or copy a curated folder into your project.

  • Project: .agents/skills/<skill-name>/SKILL.md
  • User: ~/.agents/skills/<skill-name>/SKILL.md
  • Legacy: .codex/skills/<skill-name>/SKILL.md
# Recommended (2026): install from the official openai/skills catalog
# In Codex CLI / TUI, run the bundled installer skill:
$skill-installer pdf
$skill-installer gh-fix-ci

# Or copy a curated skill folder into your project:
git clone --depth 1 https://github.com/openai/skills.git /tmp/openai-skills
cp -r /tmp/openai-skills/skills/.curated/pdf .agents/skills/pdf

Also works in `.codex/skills/`, `.cursor/skills/`, and `~/.agents/skills/` — SKILL.md is cross-compatible across Codex, Cursor, and Claude Code.
