Managing skills with gh skill

gh skill installs, previews, searches, updates, and publishes Agent Skills. An agent can use it to keep its own skill set in sync with one or more GitHub repositories.

The command is also aliased as gh skills. Prefer the canonical singular gh skill in scripts and docs.

bash
gh skill search <query>                                  # free-text search
gh skill search <query> --owner <org>                    # restrict to one owner
gh skill search <query> --limit 20 --page 2
gh skill search <query> --json skillName,repo,description

Preview before installing

bash
gh skill preview <owner>/<repo> <skill-name>
gh skill preview <owner>/<repo> <skill-name>@v1.2.0   # pin a version

Install

bash
gh skill install <owner>/<repo> <skill-name>
gh skill install <owner>/<repo> <skill-name>@v1.2.0
gh skill install <owner>/<repo> skills/<scope>/<skill-name>   # exact path, fastest
gh skill install ./local-skills-repo --from-local

<owner>/<repo> and <skill-name> are both required.

Useful flags:

  • --agent <id> - target host (e.g. github-copilot, claude-code, cursor, codex, gemini-cli). Repeat for multiple. Default is github-copilot when non-interactive. You should know what agent you are, so set this appropriately to install for yourself.
  • --scope project|user - project (default) writes inside the current git repo; user writes to the home directory and applies everywhere.
  • --pin <ref> - pin to a tag, branch, or commit SHA. Mutually exclusive with --from-local and with inline @version syntax.
  • --allow-hidden-dirs - also discover skills under dot-directories such as .claude/skills/. Don't use this unless you need to, it comes with risks.
  • --force - overwrite an existing install.

Update

bash
gh skill update --all          # update every installed skill
gh skill update <skill>        # update one
gh skill update <skill> --force
gh skill update --unpin        # drop the pin and move to latest

Publish

Publishing turns a repo into a discoverable skill source. Skills are discovered with these conventions:

  • skills/<name>/SKILL.md
  • skills/<scope>/<name>/SKILL.md
  • <name>/SKILL.md (root-level)
  • plugins/<scope>/skills/<name>/SKILL.md

Each SKILL.md needs YAML frontmatter:

yaml
---
name: my-skill                # must equal the directory name
description: One sentence...  # required, recommended <= 1024 chars
license: MIT                  # optional but recommended
---

Validate, then publish

bash
gh skill publish --dry-run                 # validate only, no release
gh skill publish --dry-run ./path/to/repo  # validate a specific dir
gh skill publish --fix                     # auto-strip install metadata
gh skill publish --tag v1.0.0              # non-interactive publish
gh skill publish                           # interactive publish flow

--fix and --dry-run are mutually exclusive. --fix only rewrites install-injected metadata.github-* keys and does not publish; commit the result and re-run publish.

The publish flow will:

  1. Add the agent-skills topic to the repo (so search can find it).
  2. Use --tag (or prompt for one in a TTY).
  3. Auto-push any unpushed commits.
  4. Create a GitHub release with auto-generated notes.

Always pass --tag so it doesn't fall through to the interactive flow.

Self-management pattern for agents

A reasonable loop:

  1. gh skill search <topic> --json skillName,repo,namespace
  2. gh skill preview <repo> <skill> to inspect the SKILL.md.
  3. gh skill install <repo> <skill> --agent <host> --pin <ref> for a reproducible install.
  4. Periodically gh skill update --all to refresh.
