/review - Pull Request Review

Review a PR using Claude's native code-review skill. Auto-detects current branch PR or accepts PR number/URL.

Trigger

/review [pr-number-or-url]

Configuration

Reads mustard.json from the project root for git.provider.

| Provider | CLI | PR detection | |----------|-----|--------------| | github | gh | gh pr view --json number,url | | gitlab | glab | glab mr view |

Behavior

• ZERO confirmations — detect PR, invoke review, done.
• ZERO questions — auto-detect if no argument provided.

---

Step 1 — Resolve PR

If argument provided

• Numeric → treat as PR number
• URL → use directly

If no argument

gh pr view --json number,url,title,headRefName 2>/dev/null

If no PR found for current branch → error:

No open PR found for current branch. Run /git merge first to create one.

---

Step 2 — Invoke Code Review

Use the Skill tool to invoke Claude's native code-review:

Skill({
  skill: "code-review",
  args: "<pr-number-or-url>"
})

If the native code-review skill is not available, fall back to local review:

Task({
  subagent_type: "general-purpose",
  model: "opus",
  description: "Review: PR <number>",
  prompt: "Review the changes in the current branch against $PARENT. Checklist: SOLID, Security, Performance, Patterns, Integration."
})

---

Step 3 — Report

Present the review results as returned by the skill/agent.

Provider Support

| Provider | Auto-detect | Manual URL | |----------|-------------|------------| | GitHub | gh pr view | yes | | GitLab | glab mr view | yes | | Bitbucket | no | yes |

---

Rules

• NEVER ask for confirmation before invoking the review
• NEVER attempt both Skill and Task — try Skill first, fall back only if unavailable
• ALWAYS use the PR number or URL directly — do NOT pass branch names to the skill
• If provider CLI is missing, instruct the user to install it; do NOT improvise

Examples

/review              # Auto-detect PR for current branch
/review 42           # Review PR #42
/review https://github.com/org/repo/pull/42

Performance Budget

• Max Bash calls: 1 (PR detection)
• Max Skill/Task calls: 1
• Max API calls total: ≤ 4
