name: review-code description: Run a multi-agent code review on recent changes. Spawns a team of specialized reviewers (bugs, security, perf, tests, usability, etc.), collects findings, triages into fix-now vs defer, and optionally applies fixes. Use when asked to "review code", "review changes", "review this PR", or "get a second opinion". disable-model-invocation: true argument-hint: [--apply] [--defer-file ]

Multi-Agent Code Review

Spawn parallel reviewer agents over recent changes; synthesize one triaged report.

Original skill by Bjorn Tipling.

Arguments

• --apply — apply the "fix now" batch after presenting findings, without asking.
• --defer-file <path> — append deferred items to this file. Default: deferred items are not written to any file.

Scope

If the branch is ahead of main, review the full branch diff (git diff origin/main...HEAD); otherwise review uncommitted changes. Exclude vendor/, generated files, go.sum.

Select Reviewers

First check the project for domain-specific reviewer skills: skills/CATALOG.md and skills/*-review/SKILL.md (convention: names ending in -review are reviewer personas). Spawn any whose domain the changeset touches. Prefer these over generic defaults — they encode conventions generic reviewers miss. Their criteria prompt is: "Read {skill-path}/SKILL.md and apply its checklist verbatim. Flag any violations."

Generic roster — pick per what the code touches:

Reviewer	Focus	Include when
bugs-reviewer	Logic bugs, edge cases, error handling, concurrency	Always — baseline
security-reviewer	Injection, path traversal, credentials, DoS	External input, file I/O, exec, network, auth
perf-reviewer	Allocations, leaks, timeouts, limit calibration	I/O, subprocesses, large data, concurrency
test-reviewer	Coverage gaps, test quality, isolation, flakiness	Changeset includes or should include tests
usability-reviewer	API ergonomics, error messages, docs, discoverability	Public API, CLI, MCP tools, config schema
integration-reviewer	SDK/framework usage vs reference patterns	Non-default: specific SDK with known patterns
arch-reviewer	Architectural fit, abstraction boundaries	Non-default: large structural changes
compat-reviewer	Breaking changes, migration paths	Non-default: public API or data format changes

Never spawn more than 6 reviewers. If project-local skills push past 6, drop the generic ones that overlap (e.g. drop bugs-reviewer if the project has a domain bug-pattern reviewer).

Spawn Team

Create a team via TeamCreate (name code-review), one task per reviewer, then spawn all reviewers in parallel with the Agent tool. Each reviewer prompt must include:

• The changed files, and the instruction to read each in full — not just the diff.
• Its review criteria (from the Focus column or the project-local skill).
• Finding format: numbered list, each with severity (Critical/High/Medium/Low/Nit), file:line, description, suggested fix.
• Report clean areas explicitly — "no issues found in X" is signal.
• Claim its task when starting, complete it when done; send findings to team-lead via SendMessage.
• Only report findings with confidence >= 80%, verified by reading the actual code before reporting.

Synthesize

If a reviewer goes idle without sending findings, prompt it once; if still silent after a second prompt, proceed without it and note the gap.

Deduplicate (keep the most detailed finding, note which reviewers flagged it), cross-validate contradictions by reading the code yourself, sort by severity.

Triage

• Fix Now (any of): Critical or High; quick fix (< 5 minutes, < 20 lines); blocks correctness or basic usability; fix is unambiguous.
• Defer (any of): needs a design decision; large scope; low real-world risk; requires changes outside the changeset.

Report

## Code Review Report

**Scope**: {branch or description}
**Reviewers**: {list of reviewers spawned}
**Files reviewed**: {count}

### Summary

| Severity | Count |
|----------|-------|
| Critical | X |
| High     | Y |
| Medium   | Z |
| Low      | W |
| Nit      | N |

### Fix Now (X items)

{numbered list with severity, file:line, description, suggested fix}

### Defer (Y items)

{numbered list with severity, description, rationale for deferring}

### Clean Areas

{what the reviewers explicitly confirmed as clean}

Apply

If --apply or the user approves: apply each Fix Now item, verify with build/lint/tests, summarize what changed.

If --defer-file: append deferred items with enough context to act on later (severity, description, rationale, suggested approach).

Clean Up

Shut down all reviewer teammates and clean up the team.
