GitHub Skill

Use the gh CLI to interact with GitHub. Always specify --repo owner/repo when not in a git directory, or use URLs directly.

Pull Requests

Check CI status on a PR:

gh pr checks 55 --repo owner/repo

List recent workflow runs:

gh run list --repo owner/repo --limit 10

View a run and see which steps failed:

gh run view <run-id> --repo owner/repo

View logs for failed steps only:

gh run view <run-id> --repo owner/repo --log-failed

Debugging a CI Failure

Follow this sequence to investigate a failing CI run:

1. Check PR status — identify which checks are failing:

   gh pr checks 55 --repo owner/repo
   

2. List recent runs — find the relevant run ID:

   gh run list --repo owner/repo --limit 10
   

3. View the failed run — see which jobs and steps failed:

   gh run view <run-id> --repo owner/repo
   

4. Fetch failure logs — get the detailed output for failed steps:

   gh run view <run-id> --repo owner/repo --log-failed
   

API for Advanced Queries

The gh api command is useful for accessing data not available through other subcommands.

Get PR with specific fields:

gh api repos/owner/repo/pulls/55 --jq '.title, .state, .user.login'

JSON Output

Most commands support --json for structured output. You can use --jq to filter:

gh issue list --repo owner/repo --json number,title --jq '.[] | "\(.number): \(.title)"'
