CodexSkills

A collection of Codex/agent skills. Check the /skills/ folder for a library of skills (like the OpenAI Developer Documenation Skill or Codex Subagents Skill)

Available skills

• codex-subagent: Spawn autonomous Codex subagents via background shell to offload context-heavy work (web research, codebase exploration, multi-step workflows). Uses YOLO mode by default with smart model selection (mini for pure search, inherit parent for multi-step tasks).
• context7: Fetch up-to-date library documentation via Context7 API.
• openai-docs-skill: Query OpenAI developer docs via the OpenAI Docs MCP server using CLI.
• frontend-design: Distinctive frontend design system guidance (imported from Anthropic).
• frontend-responsive-ui: Responsive UI standards (imported from Anthropic).
• playwright-skill: Browser automation/testing helper that auto-detects dev servers, runs Playwright scripts, captures UX data, and stores scripts in /tmp.
• gemini-computer-use: Gemini 2.5 Computer Use browser-control agent skill (Playwright + safety confirmation loop).
• agent-browser: Fast Rust-based headless browser automation CLI from Vercel Labs with snapshot/act pattern for AI agents.
• vercel-react-best-practices: React/Next.js performance guidance (imported from Vercel).
• read-github-docs: Read and search GitHub repository documentation via gitmcp.io MCP service. Converts github.com/owner/repo URLs to gitmcp.io/owner/repo for LLM-friendly access to repos.

Note on Browser Tools: The repo includes three browser automation tools (playwright-skill, gemini-computer-use, and agent-browser). You don't need to install all of them as they all do similar things - choose the one that best fits your workflow. I recommend agent-browser.

Note on Context7: This skill requires a Context7 API key in CONTEXT7_API_KEY. See skills/context7/.env.example and the Authentication section in skills/context7/SKILL.md.

Note on Gemini Computer Use Skill: This skill requires a GEMINI_API_KEY. Ask Codex to help you set it up.

Note on read-github-docs: This skill provides CLI access to any GitHub repository's documentation via the gitmcp.io service. Usage:

# Fetch full documentation
python3 scripts/gitmcp.py fetch-docs owner/repo

# Search documentation
python3 scripts/gitmcp.py search-docs owner/repo "query"

# Search code
python3 scripts/gitmcp.py search-code owner/repo "function_name"

Note on Codex Subagents Skill:

You must turn on Background Terminal for subagents. In fact, turn on all of these features. They're all incredible.

Install with codexskills (recommended)

Install a single skill into your user scope (installs globally for all projects):

npx @am-will/codexskills --user am-will/codex-skills/skills/codex-subagent

Install all skills (or pick from the list):

npx @am-will/codexskills --user am-will/codex-skills/skills

Install into a project (install to just one specific project):

npx @am-will/codexskills --project am-will/codex-skills/skills /path/to/your/project

Install skills from other Github repositories:

All of the above commands work for any Github Skill repository:

npx @am-will/codexskills --project https://github.com/numman-ali/n-skills/tree/main/skills /path/to/your/project

Install globally and use codexskills directly:

npm install -g @am-will/codexskills
codexskills --user am-will/codex-skills/skills

Notes:

• When multiple skills are found, codexskills prompts you to choose (space to toggle, enter to confirm).
• When you post a path to just one skill, it will not prompt you "are you sure?"
