Review Work

Independently verifies implementation results using only the plan document and the codebase. Receives no information from the execution process.

Core Principle

The reviewer shares no memory with the executor. The plan's stated goals and the current state of the codebase — these two alone are the basis for judgment.

Hard Gates

1. Do not receive execution context. No logs from run-plan, no worker output, no diffs, no task completion summaries, no conversation history. The only input is the plan file path.
2. Read the plan document directly. Read the plan file from disk — not a summary or a passed-along description.
3. Run all tests yourself. Do not trust previous execution results. Run the full test suite and every verification command specified in the plan.
4. Verdict is PASS or FAIL. No conditional passes, no "almost done", no "only minor issues remain". Binary only.
5. Save the review document to a file. Review results must be saved as a structured document. Never end with a verbal report alone.
6. Do not modify code. This skill is read-only. If issues are found, report them — do not fix them.

When To Use

• After run-plan execution is complete
• When the user says "review the work", "verify the implementation", "check if the plan was executed correctly"
• When implementation is done but independent verification is needed

When NOT To Use

• While run-plan is still in progress
• When no plan document exists (use plan-crafting first)
• When the goal is a general code review (this skill verifies "implementation against plan")

Input

The only input to this skill is the plan file path.

docs/engineering-discipline/plans/YYYY-MM-DD-<feature-name>.md

The following must never be provided as input:

• Execution logs or task completion summaries from run-plan
• Output or diffs from worker subagents
• Validation results from validator subagents
• Conversation history from the execution session

Process

Phase 1: Load and Analyze Plan Document

1. Receive the plan file path as input
2. Read the plan document directly from disk
3. Extract the following:
   • Goal: What this plan implements
   • Work Scope: In scope / Out of scope
   • Task List: Each task's name, acceptance criteria, and target files
   • File Structure Mapping: Complete list of files to be created or modified
   • Commit Structure: Commit messages and scope specified in the plan
   • Test Commands: All test execution commands specified in the plan

Use the extracted results as the foundation for the review document.

Phase 2: Codebase Inspection

Inspect the codebase against the files specified in the plan.

1. File existence check: Verify that all files specified in the plan actually exist
2. Content alignment check: Inspect whether each file's content matches the plan's requirements (function signatures, type definitions, logic, etc.)
3. Residual artifact check:
   • Placeholder code (TODO, FIXME, "implement later", stub functions)
   • Debug code (console.log, print debugging, commented-out code blocks)
   • Unexpected changes outside the plan's scope
4. Verify acceptance criteria per task. Check each criterion stated in the plan one by one and record whether it is met.

Phase 3: Test Execution

1. Run all individual test commands specified in the plan
2. Run the full test suite to check for regressions
3. Record each test's result (PASS/FAIL)
4. If any test fails, record the error message

Phase 4: Git History Verification

1. Compare the commit structure specified in the plan against the actual git log
2. Verify that commit messages match the plan
3. Verify that each commit's change scope is appropriate (no unrelated changes mixed into a single commit)

Phase 5: Verdict and Review Document

Combine results from Phases 2–4 to reach a verdict.

PASS conditions (all must be met):

• All files specified in the plan exist
• Each task's acceptance criteria are met
• All tests pass
• No regressions
• No placeholder or debug code remains

FAIL (if any of the following apply):

• A file specified in the plan is missing
• A test fails
• A regression is found
• Placeholder code remains
• The plan's goal is not achieved

After reaching a verdict, write and save the review document.

Document Structure

# [Feature Name] Review

**Date:** YYYY-MM-DD HH:MM
**Plan Document:** `docs/engineering-discipline/plans/YYYY-MM-DD-<feature-name>.md`
**Verdict:** PASS / FAIL

---

## 1. File Inspection Against Plan

| Planned File | Status | Notes |
|---|---|---|
| `path/to/file` | OK / Missing / Mismatch | Details |

## 2. Test Results

| Test Command | Result | Notes |
|---|---|---|
| `pytest tests/...` | PASS / FAIL | Error details if failed |

**Full Test Suite:** PASS / FAIL (N passed, M failed)

## 3. Code Quality

- [ ] No placeholders
- [ ] No debug code
- [ ] No commented-out code blocks
- [ ] No changes outside plan scope

**Findings:**
- (Describe with file path and line number)

## 4. Git History

| Planned Commit | Actual Commit | Match |
|---|---|---|
| `feat: add X` | `abc1234 feat: add X` | OK / Mismatch |

## 5. Overall Assessment

(Summary of the overall judgment. If FAIL, describe specifically which items failed and why.)

## 6. Follow-up Actions

- (If FAIL: list of items that need to be fixed)
- (If PASS: record improvement suggestions if any)

When To Stop

Stop immediately and notify the user in the following situations:

• The plan file does not exist or cannot be read
• The test execution environment is not ready (e.g., dependencies not installed)
• The plan document format cannot be parsed

When in doubt, do not guess — ask the user.

Anti-Patterns

Anti-Pattern	Why It Fails
Reading run-plan execution logs to verify	Information isolation violation. Anchors on the executor's framing
Trusting previous test results instead of running tests	Environment may have changed after execution. Not independent verification
Finding issues and fixing them directly	Violates separation of reviewer and implementer roles
Giving a "close enough, PASS" verdict	No conditional passes. If criteria are not met, it is FAIL
Delivering review results verbally without saving a document	No verification record remains. Untraceable
Judging by criteria not in the plan	The reviewer judges only by the plan's criteria. Adding arbitrary standards is prohibited
Receiving a plan summary and verifying from that	Information is lost during summarization. The original must be read directly

Minimal Checklist

Self-check when review is complete:

• Read the plan document directly from disk
• Did not receive run-plan execution results as input
• Ran all tests myself
• Inspected all tasks in the plan
• Verdict is either PASS or FAIL
• Saved the review document to a file

Transition

After review is complete:

• PASS → Report results to the user and suggest next steps (PR creation, deployment, etc.)
• FAIL → Report failure items to the user. If fixes are needed, suggest transitioning to the run-plan or systematic-debugging skill
• If the plan itself has issues → suggest returning to the plan-crafting skill to revise the plan

This skill itself does not invoke the next skill. It saves the review document, reports results, and lets the user decide the next step.
