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

• scripts/install-skill-from-github.py --repo <owner>/<repo> --path <path/to/skill> [<path/to/skill> ...]

• scripts/install-skill-from-github.py --url https://github.com/<owner>/<repo>/tree/<ref>/<path>

Behavior and Options

• Defaults to direct download for public GitHub repos.
• If download fails with auth/permission errors, falls back to git sparse checkout.
• Aborts if the destination skill directory already exists.
• Installs into

  $CODEX_HOME/skills/<skill-name>

  (defaults to

  ~/.codex/skills

  ).
• Multiple

  --path

  values install multiple skills in one run, each named from the path basename unless

  --name

  is supplied.
• Options:

  --ref <ref>

  (default

  main

  ),

  --dest <path>

  ,

  --method auto|download|git

  .

Notes

• Curated listing is fetched from

  https://github.com/openai/skills/tree/main/skills/.curated

  via the GitHub API. If it is unavailable, explain the error and exit.
• Private GitHub repos can be accessed via existing git credentials or optional

  GITHUB_TOKEN

  /

  GH_TOKEN

  for download.
• Git fallback tries HTTPS first, then SSH.
• The skills at https://github.com/openai/skills/tree/main/skills/.system are preinstalled, so no need to help users install those. If they ask, just explain this. If they insist, you can download and overwrite.
• Installed annotations come from

  $CODEX_HOME/skills

  .
