Code Review Workflow

Review target: $ARGUMENTS

Specify what to review. Accepted formats:

• A branch name: feature/my-branch
• A file or set of files: src/api/UserController.kt
• A pull request reference: PR #42
• Empty — defaults to the current working diff (git diff)

Web interface scope

When the task concerns web layout, component states, feedback, motion, or a requested UI audit, apply skill web-design-engineering from the installed skill library. Use it during intake/discovery, design, test/implement, and review as applicable; keep this workflow’s gates and TDD order. Framework presence alone does not activate it; backend-only and native mobile work are excluded. Record required visual checks as pending when unavailable. Keep findings in the existing Review Report: contract failures in Spec Axis, technical issues in existing subchecks, and aesthetic preferences as suggestions; do not add an axis.

Android phone interface scope

When the task concerns concrete Jetpack Compose phone layout, component states, interaction, accessibility, visual behavior, or a requested UI audit, apply skill android-ui-design. Use it during design, test/implementation, and review as applicable while keeping this workflow's gates and TDD order. Kotlin, Compose, framework, or dependency presence alone does not activate it; non-UI Android work stays with the general android skill. Audit-only requests remain read-only, and unavailable visual or emulator checks remain pending rather than claimed complete.

Step 1 — Diff collection

Before invoking reviewer, collect the diff for the specified target.

If $ARGUMENTS is empty or not provided:

• Use git diff HEAD as the review target

If $ARGUMENTS is a branch name:

• Use git diff main...$ARGUMENTS (or develop if main is not the base)

If $ARGUMENTS is a PR reference:

• Retrieve the PR diff and the PR description for context

If $ARGUMENTS is a file path:

• Use git diff HEAD -- $ARGUMENTS

Show the diff summary (files changed, lines added/removed) before invoking reviewer.

Step 2 — Security and code review

Security review (security-reviewer)

Invoke security-reviewer before reviewer when the change touches:

• Authentication or authorization logic
• Payment or financial processing
• Credentials, tokens, secrets, or API keys
• SQL injection, XSS, or other injection vectors
• Supply-chain dependencies (new packages, lockfile changes)
• OWASP Top 10 categories

security-reviewer performs deep security analysis and can apply a security veto that overrides majority consensus:

• When securityVeto: true and verdict is REJECTED, the veto forces the final status to REJECTED regardless of other reviewers' opinions
• The veto agent ID is recorded in vetoByAgentId for traceability

If security-reviewer applies a veto, the review is BLOCKED — all CRITICAL findings must be resolved before proceeding.

Code review (reviewer)

Invoke reviewer with:

• The full diff
• The Task Card or PR description (if available)
• The target specification from $ARGUMENTS
• The security-reviewer report (if one was generated)

reviewer must evaluate the diff against the following checklist:

Correctness

• Does the implementation match the stated intent?
• Are there logic errors, off-by-one errors, or unhandled edge cases?

Architecture alignment

• Does the change follow existing module boundaries?
• Does it introduce unplanned coupling or layering violations?

Security

• Are inputs validated before use?
• Is there any credential, token, or secret in the diff?
• Are there SQL injection, XSS, or injection risks?

Performance

• Does the change introduce N+1 queries, blocking I/O, or O(n^2) loops?

Test coverage

• Do tests exist for the new or changed behavior?
• Are assertions meaningful (not just checking that no exception is thrown)?

Documentation

• Are public interfaces documented?
• Is CHANGELOG updated if behavior changed?

Step 3 — Review Report

reviewer produces a structured Review Report with findings in three categories:

## Review Report

### CRITICAL

[Findings that must be fixed before merge. Each finding includes:

- Location (file:line)
- Description of the problem
- Suggested resolution]

### WARNING

[Findings that should be resolved before merge but are not blockers in
exceptional cases with human approval. Same format as CRITICAL.]

### SUGGESTION

[Optional improvements — style, readability, future-proofing. These do not block
merge.]

### Summary

- Files reviewed: N
- Total findings: N (X critical, Y warnings, Z suggestions)
- Merge recommendation: APPROVED | BLOCKED

Step 4 — Merge decision

If any CRITICAL findings exist:

• The Review Report status is BLOCKED
• Report all CRITICAL findings to the human
• Do not proceed until each CRITICAL finding is resolved
• After resolution, invoke /cc:review again on the same target

If no CRITICAL findings exist:

• The Review Report status is APPROVED
• Report any WARNINGs and SUGGESTIONs for human awareness
• The human makes the final merge decision

Completion

Deliver the complete Review Report. Never summarize or omit findings. Every finding must include a location and an actionable description.
