What it does

Use this skill to review code. It supports both local changes (staged or working tree) and remote Pull Requests (by ID or URL). It focuses on correctness, maintainability, and adherence to project standards.

Code Reviewer

This skill guides the agent in conducting professional and thorough code reviews for both local development and remote Pull Requests.

Workflow

1. Determine Review Target

Remote PR: If the user provides a PR number or URL (e.g., "Review PR #123"), target that remote PR.
Local Changes: If no specific PR is mentioned, or if the user asks to "review my changes", target the current local file system states (staged and unstaged changes).

2. Preparation

For Remote PRs:

Checkout: Use the GitHub CLI to checkout the PR.
```
gh pr checkout <PR_NUMBER>
```
Preflight: Execute the project's standard verification suite to catch automated failures early.
```
npm run preflight
```
Context: Read the PR description and any existing comments to understand the goal and history.

For Local Changes:

Identify Changes:
- Check status: git status
- Read diffs: git diff (working tree) and/or git diff --staged (staged).
Preflight (Optional): If the changes are substantial, ask the user if they want to run npm run preflight before reviewing.

3. In-Depth Analysis
