Skill System GitHub

Run consistent GitHub operations through gh with explicit safety checks for workflow writes and predictable return shapes.

Decision Matrix

| Task Intent | Operation | Primary Backend | Notes | |---|---|---|---| | Create/list/comment/close/reopen issues | manage-issues | gh issue | Check duplicates before creating new issues | | Create/update/delete labels, apply labels to issue | manage-labels | gh label, gh issue edit | Confirm destructive delete before execution | | Bootstrap/update issue templates | manage-templates | file read/write tools | Edit .github/ISSUE_TEMPLATE/* directly | | List/check/create/update workflows | manage-workflows | gh workflow, file read/write tools | Run safety-check before pushing workflow changes | | Decide workflow push path based on token scope | safety-check | gh auth status, gh api | Use API fallback when workflow scope is missing |

Core Patterns

Pattern 1: Resolve repository and perform issue operation

gh issue list --repo <owner/repo> --state open --limit 50
gh issue create --repo <owner/repo> --title "<title>" --body "<body>"

Pattern 2: Label lifecycle and issue label application

gh label create "<name>" --repo <owner/repo> --description "<desc>" --color "<hex>"
gh label edit "<name>" --repo <owner/repo> --new-name "<new>" --description "<desc>" --color "<hex>"
gh issue edit --repo <owner/repo> <number> --add-label "<label1>,<label2>"

Pattern 3: Workflow visibility and recent run checks

gh workflow list --repo <owner/repo>
gh run list --repo <owner/repo> --workflow "<name>" --limit 5

Pattern 4: Workflow scope gate before writing .github/workflows/*

gh auth status
gh api repos/<owner>/<repo>/contents/.github/workflows/<file> \
  --method PUT \
  -f message="update workflow via api" \
  -f content="<base64-content>" \
  -f branch="<branch>"

Guidelines

  • Always resolve owner/repo first; infer from git remote get-url origin when not provided.
  • Always check duplicate issue titles before issue creation.
  • Always ask for explicit confirmation before label deletion.
  • Always run safety-check before workflow writes that require push permissions.
  • Always use file tools for .github/ISSUE_TEMPLATE/* and .github/workflows/* edits.
  • Never include secrets in issue/comment/template/workflow bodies.
  • Return structured output with status, url, and error fields for all operations.
