Tokens, turns and time describe resource use, not a dollar price.
One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.

The instructions your model reads when the skill loads.
Orchestrates GitHub PR workflows for AI code review. Provides tools to list pull requests, post inline review comments, apply labels based on review findings, and (with explicit opt-in) auto-merge clean PRs.
All GitHub API interactions go through the gh CLI. Direct HTTP requests and web searches are denied to ensure all operations are auditable and respect GitHub's rate limiting.
export GH_TOKEN="ghp_..."
The token needs read-write access since this skill posts comments, applies labels, and can merge PRs:
| Scope (classic PAT) | Fine-grained permission | Why |
|---|---|---|
repo | Pull requests: Read & Write | List PRs, post review comments, merge |
repo | Contents: Read | Read PR diff and file contents |
repo | Issues: Write | Apply and remove labels |
read:org (optional) | Organization: Read | Org-level label policies |
Minimum fine-grained token permissions: pull_requests: write, contents: read, issues: write on the target repository.
For read-only review without GitHub interaction, use the code-review skill instead — it only needs read access.
| Variable | Required | Description |
|---|---|---|
| GH_TOKEN | yes | GitHub personal access token or fine-grained token |
| REVIEW_AUTO_MERGE | no | Set to true to enable guarded auto-merge. Default: disabled |
| REVIEW_LABEL_PREFIX | no | Prefix for review labels (default: review/). Labels: review/approved, review/needs-changes, review/security-concern |
List open pull requests for a repository, optionally filtered by author or label.
