Skills

Forget about MCP1; use command-line tools and tailor context to the task at hand.
Note
Unsolicited advice: try to stay away from snake oil and cruft. The best skill is no skill. Seriously, only write skills to update or steer clankers if you want to adjust their “out-of-the-box” behavior. The models are good, they know what they are doing (in like 89% of the cases2).
Use with Codex, Claude Code, Pi.
Install
git clone git@github.com:bkircher/skills.git ~/src/skills
… or something like this. You can also clone somewhere else and symlink to the agent-specific directories.
Test
Start Codex as normal:
codex -m gpt-5.3
(before Codex version 0.80.0, pass --enable skills feature flag):
codex --enable skills -m gpt-5.2
Then, when prompted:
> list skills
Should output something like:
• Available skills:
- english-text-editor
- gh-address-comments
- gh-code-review
- gh-run-failure
- git-commit-message
- jira-read-ticket
Use with Codex
Skills are still a work in progress (as of Codex 0.72.0) 3. Run Codex with:
codex --enable skills. For example:
codex --enable skills -m gpt-5.2-codex -s workspace-write -a on-request
Tested with:
codex --version
codex-cli 0.72.0
Use with Claude Code
Claude Code supports skills out of the box. Make sure the skills are installed, e.g.,
cd ~/.claude
ln -s $HOME/src/skills skills
Then in Claude CLI:
> list skills
