Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill Installer
Helps install skills. By default these are from <https://github.com/openai/skills/tree/main/skills/.curated>, but users can also provide other locations.
Use the helper scripts based on the task:
- List curated skills when the user asks what is available, or if the user uses this skill without specifying what to do.
- Install from the curated list when the user provides a skill name.
- Install from another repo when the user provides a GitHub repo/path (including private repos).
Install skills with the helper scripts.
## Communication
When listing curated skills, output approximately as follows, depending on the context of the user's request:
"""
Skills from {repo}:
1. skill-1
2. skill-2 (already installed)
3. ...
Which ones would you like installed?
"""
After installing a skill, tell the user: "Restart Codex to pick up new skills."
## Scripts
All of these scripts use network, so when running in the sandbox, request escalation when running them.
- `scripts/list-curated-skills.py` (prints curated list with installed annotations)
- `scripts/list-curated-skills.py --format json`

How to install
mdr add akiojin/llmlb/skill-installer@sha256:fcd8b00b7b8194a3The line at the top of this page pins the label git:20251220.8162c99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
