Review

Final gate between /tdd completion and PR creation. Phase 1 ensures the suite is healthy. Phase 2 reviews code against the plan and standards. If Phase 2 fixes break tests, loop back to Phase 1.

Handles output from one or more /tdd runs on the same branch.

Prerequisites

• •/tdd has completed on this branch
• •.plans/issue-{issue-number}/plan.md exists (every issue gets a plan)

Process

Phase 1: Suite Health

1.0 Environment Setup

Verify infrastructure before running tests:

# Verify backend venv exists
make test-backend ARGS="--version"

# Verify frontend node_modules
ls frontend/node_modules/.bin/vitest

If venv or node_modules don't exist, run make setup first.

1.1 Run Full Suite

This is the single authoritative cross-layer test run. TDD sub-agents only verify their own layer — this is where cross-layer regressions surface.

make test-backend
make test-frontend
make test-e2e

Collect all failures.

1.2 Categorize Failures

Separate failures into:

All failures are caused by this branch — main is always green.

1.3 Present Each Failure

For each existing test failure caused by the new feature, use AskUserQuestion:

Present:

• •Test name and file
• •What it asserts (the old behavior)
• •Why it fails (the new behavior)
• •Relevant code diff if helpful

Options:

• •Update test — modify assertions to reflect new correct behavior
• •Remove test — this scenario no longer applies
• •This is a bug — the feature broke something it shouldn't have; needs fixing
• •Skip for now — revisit later

Group related failures by topic when possible (e.g., "These 4 tests all assert the old response format for GET /recipes").

1.4 Execute Decisions

Context management: Spawn a general-purpose sub-agent (via Task tool) when a fix requires reading multiple files or making coordinated changes across files. Do simple single-file edits (update one assertion, delete one test) inline.

When spawning a sub-agent, provide:

• •The specific test file(s) and line numbers
• •What the old behavior was and what the new behavior is
• •The exact decision (update/remove)
• •Instructions to run the affected test file after the fix

For each decision:

• •Update test: Modify the test to assert new behavior. Run the specific test to confirm pass.
• •Remove test: Delete the test. If it was the only test for that behavior, ask if replacement coverage is needed.
• •Bug: Create a LEARNING task noting the regression. Fix the bug before continuing.
• •Skip: Leave as-is, note it for later.

1.5 Database Migrations

Evaluate code changes for database impact:

• •Check for new/modified models, schema changes, or new fields
• •Check for changed relationships or constraints
• •Check for renamed or removed columns/tables

If database changes are detected, present to user via AskUserQuestion:

• •What changed (model/field/relationship)
• •Whether a migration is needed
• •Suggested migration approach

If no database changes detected, skip this step.

1.6 Verify Suite Health

After all decisions are executed:

• •Run only the affected layers again
• •If new failures appear, repeat from 1.3
• •Once affected layers are green, run the full suite one final time:
  bash

  make test-backend
  make test-frontend
  make test-e2e
  

• •Continue until suite is green or only skipped/bug items remain

Phase 2: Code Review

2.1 Gather Context

• •Read the plan: .plans/issue-{issue-number}/plan.md
• •Get the full diff: git diff main...HEAD
• •List all changed files: git diff main...HEAD --name-only

2.2 Spawn Review Agents

Spawn 4 independent review sub-agents (Task tool, subagent_type="general-purpose"):

Plan conformance reviewer:

Compare this implementation against its plan.

Plan:
[plan.md content]

Changed files:
[file list]

For each feature in the plan, evaluate:
- Is it fully implemented? (all acceptance criteria met)
- Is anything missing?
- Was anything added that isn't in the plan?
- Does the approach match what was specified?

Report:
- IMPLEMENTED: criteria met as planned
- DEVIATED: implemented differently than planned (explain how)
- MISSING: planned but not implemented
- EXTRA: implemented but not in plan

Standards conformance reviewer:

Review these code changes against project standards.

Changed files:
[file list]

Read the project's CLAUDE.md and relevant subdirectory CLAUDE.md files.
Check each changed file against the standards defined there.

Evaluate:
- Naming conventions followed?
- File organization correct?
- Patterns match established codebase conventions?
- Error handling consistent with project style?
- Test structure follows testing standards?

Report each violation with:
- File and line
- What standard is violated
- What it should be instead

Quality reviewer:

Review these code changes for quality issues.

Changed files:
[file list]

Read the changed files and evaluate:
- Dead code or unused imports introduced?
- Overly complex logic that could be simplified?
- Missing error handling at system boundaries?
- Hardcoded values that should be configurable?
- Security concerns (injection, XSS, exposed secrets)?
- Performance concerns (N+1 queries, unnecessary re-renders)?

Report only concrete issues, not style preferences.

Docs-update reviewer:

Review these code changes for documentation impact.

Changed files:
[file list]

Read ALL durable context files:
- CLAUDE.md (root)
- backend/CLAUDE.md
- frontend/CLAUDE.md
- e2e/CLAUDE.md
- All files in docs/

For each changed file, evaluate:
- Does it introduce a new pattern, convention, or architectural decision
  that should be recorded in a CLAUDE.md or docs/ file?
- Does it change existing behavior that is currently documented?
- Does it add a new dependency, command, or configuration that should
  be mentioned in setup/quick-start docs?

Report:
- STALE: existing documentation that no longer matches the code
- MISSING: new patterns or conventions that should be documented
- OK: no documentation impact

Only flag concrete gaps. Do not suggest adding docs for trivial changes.

2.3 Present Findings

Summarize all reviewer findings grouped by severity:

Must fix (blocks PR):

• •Missing acceptance criteria
• •Standards violations
• •Security issues

Should fix (improves quality):

• •Deviations from plan approach
• •Quality concerns
• •Minor standards issues

Note (informational):

• •Extra features added beyond plan
• •Suggestions for future improvement

For each finding, use AskUserQuestion:

• •Present the issue
• •Options: fix now / accept as-is / create follow-up issue

2.4 Execute Fixes

Context management: Spawn a general-purpose sub-agent (via Task tool) when a fix touches multiple files or requires reading surrounding code. Do simple single-file cosmetic edits inline.

For "fix now" decisions:

• •Make the change
• •If the fix could break tests → loop back to Phase 1 (re-run suite from 1.1)
• •If the fix is cosmetic only → run lint/typecheck for the affected layer

Phase 2.5: Friction Resolution

Check for .plans/issue-{issue-number}/friction.md. If it exists, /tdd recorded friction during execution that needs resolution here.

For each friction entry:

1. •Read the entry and understand the gap
2. •Determine the appropriate resolution:
   • •Durable context update — update CLAUDE.md, docs/, or scripts to prevent recurrence (e.g., a repeated bash failure → add a make target or document the correct command)
   • •Breaking test resolution — existing tests broke due to intentional behavior changes during GREEN phase. Present to user with same options as Phase 1.3 (update/remove/bug/skip)
   • •Incomplete task — a task left in_progress after 3 failures. Diagnose the root cause, fix the underlying issue, and complete the task
   • •Follow-up issue — the friction reveals a larger problem that shouldn't block this PR
3. •Present each friction item to the user via AskUserQuestion with resolution options
4. •Execute the resolution
5. •If any resolution changes code or tests → loop back to Phase 1 (re-run suite)

After all friction is resolved, delete the friction file.

Phase 3: Final Gate

1. •Confirm no unaddressed must-fix items remain
2. •Confirm suite is green (from Phase 1, or re-verified after Phase 2 fixes)
3. •Run lint/typecheck if any Phase 2 cosmetic fixes were made:
   bash

   make lint
   make typecheck
   

4. •Post summary comment on the GitHub issue

Summary

Present final state:

• •Suite health: Tests updated [count], removed [count], migrations [count], bugs [count], skipped [count]
• •Friction resolved: [count] — durable context updates [count], breaking tests fixed [count], incomplete tasks completed [count]
• •Plan conformance: [percentage of criteria fully implemented]
• •Standards issues fixed: [count]
• •Quality issues fixed: [count]
• •Accepted deviations: [list]
• •Follow-up issues created: [list]
• •Suite status: GREEN / remaining failures

Tell the user: "Review complete. Ready for PR."

Principles

• •Suite green is non-negotiable — the branch must pass all tests before PR
• •Plan is the source of truth — deviations need justification
• •Standards are non-negotiable — must-fix, not suggestions
• •Quality is contextual — only flag concrete issues, not preferences
• •User decides — never update or remove a test without explicit approval
• •Group related failures — don't ask about 10 tests one at a time if they're the same issue
• •Bugs get fixed, not deferred — if the feature broke something unintentionally, fix it here
• •Phase 2 fixes that break tests loop back — no skipping the suite re-run
