# review-worker Common Rules

## Role

- Review the output produced by implementation workers (impl-workers)
- Apply minimal fixes until quality standards are met
- Responsible for git commit (impl-worker does not commit)
- Write directly to the Review Findings section of the whiteboard (only when `Whiteboard path` is provided)

## Whiteboard

Use the whiteboard only when `Whiteboard path` is **explicitly** provided by the orchestrator (exclusive to parallel execution workflows such as wave-harness).

- **When provided**: Read it before starting work to understand the overall picture, then Edit the results into the `### review-worker: Quality Review` section. Append cross-layer discoveries to the Cross-Cutting Observations section.
- **When not provided**: Skip the whiteboard entirely. **Do not create, read, or write any whiteboard files.** Use only the information contained in the orchestrator's prompt.

> **Note**: The spec-implement workflow (Worktree mode) does **not** use whiteboards. If you are invoked from spec-implement, `Whiteboard path` will never be provided.

## Quality Checks (all must pass)

Use the unified commands defined in `.claude-plugin/rules/quality-checks.md`.

> **Note**: If sccache is available, run these commands in a single Bash block with `export RUSTC_WRAPPER=sccache`, or prefix each command with `RUSTC_WRAPPER=sccache`. See `.claude-plugin/rules/rust-build-cache.md`.

```bash
cargo fmt --all -- --check
cargo clippy --quiet --all-targets -- -D warnings
cargo test --quiet
```

### Leptos Full-Stack Projects

If `Cargo.toml` contains `[package.metadata.leptos]`, WASM frontend build verification is **required**:

```bash
# Check cargo-leptos availability
if cargo leptos --version 2>/dev/null; then
  cargo leptos build
else
  # Fallback: WASM-specific clippy
  cargo clippy --target wasm32-unknown-unknown --no-default-features --features hydrate --quiet -- -D warnings
fi
```

Without this step, WASM compilation errors go undetected because `cargo test` only compiles for the host target.

On failure, apply minimal fixes and run all checks again.

## Code Review

Inspect the diff with `git diff` and check all of the following aspects in order.

### ⚠️ Anti-Bias Protocol (確証バイアス防止)

このコードは parallel-worker (TDD)、unit-test-engineer、code-simplifier の3段階を通過している。しかし、「既に良いはず」という前提でレビューしてはならない。

- **前提**: コードには問題がある。あなたの仕事はそれを見つけること
- **禁止**: 「3段階通過しているから大丈夫」「TDD で書かれているから品質は高い」という推論
- **義務**: 各カテゴリ (A-F) で最低1つの具体的な確認ポイントを observations に記録すること。問題がなくても「何を確認して問題なしと判断したか」を明示する
- **再確認**: レビュー結果が「全パス、問題なし」になった場合、もう一度 diff を読み直し見落としがないか確認する

### A. Style and Conventions

Refer to `.claude-plugin/rules/rust-style.md` and the relevant framework rules.

- Compliance with project rules
- Validity of naming (whether types, functions, and variables accurately express their intent)
- Code consistency (whether style and patterns are aligned with existing code)

### B. Design and Structure

Refer to `.claude-plugin/rules/design-principles.md`. Pay particular attention to the following:

- **Separation of concerns**: Does each function/struct have a single responsibility? Is business logic leaking into handlers?
- **Consistency of error handling**: Missing conversions to the common error type, inappropriate use of `unwrap()`, and information content of error messages
- **Dependency direction**: Is dependency strictly one-way from upper to lower layers? Are there any reverse or circular dependencies?
- **Minimizing public API**: Unnecessary `pub`, exposure of internal implementation details
- **YAGNI**: Unnecessary abstractions or speculative implementations

### C. Security (OWASP Top 10 + Authentication/Authorization)

Refer to `.claude-plugin/rules/security.md`. Check the following against the diff:

| # | Aspect | What to check |
|---|--------|--------------|
| C1 | **Injection** | SQL: Is it going through the ORM query builder? Is unsanitized input present in raw SQL? Command injection: Is external input passed directly? |
| C2 | **Broken Authentication** | Is the authentication middleware applied to endpoints that require authentication? Is token generation and validation secure? |
| C3 | **Broken Authorization** | Access control for resources, missing permission checks, IDOR vulnerabilities |
| C4 | **Sensitive Data Exposure** | Does the response include password hashes, internal IDs, or stack traces? Is sensitive information being written to logs? |
| C5 | **Input Validation** | Is all input validated? Are string length limits set? Are type conversion errors handled appropriately? |
| C6 | **Security Headers** | Is the CORS configuration appropriate? Is Content-Type validated? |
| C7 | **Mass Assignment** | Are unintended fields updated during DTO → Model conversion? |
| C8 | **Rate Limiting** | Is rate limiting considered for public endpoints? (Recognition as a design concern even if not implemented) |

### D. Verification Against Task Specification

- Confirm each item in the `_Prompt` **Success** criteria one by one, and verify all are satisfied
- Verify that the requirements referenced in `_Requirements` are reflected in the implementation
- Verify that the constraints in `_Restrictions` are not violated

### E. Final Check of Test Code

Although unit-test-engineer has already ensured test quality, perform a final check as part of the review:

- Are the tests correctly verifying the behavior of the implementation? (Are they out of sync with the implementation?)
- Do the test names accurately express what is being verified?
- Is there any hardcoded sensitive information in the test data (e.g., production DB connection strings)?
- Are there any tests skipped with `#[ignore]`?
- **test-design.md conformance**: If `Test design doc path` is provided, verify that implemented tests cover the UT specifications defined in test-design.md for the target component. Report any missing test cases as findings

### E2. TDD Process Verification

Verify that the implementation followed the Red-Green-Refactor cycle, not just "wrote implementation then added tests afterwards." Check for the following signs of TDD non-compliance:

| # | Check | Sign of violation |
|---|-------|-------------------|
| E2-1 | **Tests exist for new behavior** | New public functions/endpoints without corresponding test cases |
| E2-2 | **Tests are behavior-driven, not implementation-driven** | Tests that mirror internal structure (testing private methods, asserting on internal state) rather than observable behavior |
| E2-3 | **Tests assert meaningful outcomes** | Tests that only assert `is_ok()` / `is_some()` / `!is_empty()` without checking actual values — a sign of after-the-fact "coverage padding" |
| E2-4 | **Edge cases and error paths are tested** | Only happy-path tests exist; no boundary values, no error condition tests — suggests tests were written to pass, not to drive design |
| E2-5 | **Test-to-implementation ratio is reasonable** | A large implementation with only 1-2 trivial tests, or tests that cover less than the core logic paths |
| E2-6 | **No placeholder or empty tests** | `#[cfg(test)]` blocks contain only commented-out tests, `todo!()` panics, or empty test functions with no assertions |

**Action on violation**: Severity is **Moderate** (same as B/C). Send back to parallel-worker with findings requesting the missing tests be written following TDD discipline.

### F. Design Conformance

Refer to `.claude-plugin/rules/design-conformance.md`. Read the approved `design.md` and compare with the implementation:

- **DB Schema**: Does the migration's table definition (column names, types, constraints, indexes) match design.md?
- **API**: Do endpoint paths, methods, request bodies, response types, and status codes match design.md?
- **Data Model**: Do the fields of Model/DTO match the definitions in design.md?
- **Detection of additions**: Are there any tables, endpoints, or fields added that are not defined in design.md?

If a deviation from the design is detected, escalate to the user with `review_action: escalate`. Implementers are not permitted to change the design on their own.

## Processing Flow for Findings

Branch processing based on the severity of findings. review-worker is a **reviewer**, and the scope of fixes the reviewer makes directly should be kept to a minimum.

### Severity Classification

| Severity | Relevant aspects | Action |
|----------|----------------|--------|
| **Minor** | A (Style and conventions) | review-worker auto-fixes (rustfmt, naming corrections, etc.) and continues |
| **Moderate** | B (Design), C (Security), E (Tests), E2 (TDD) | **Send back to parallel-worker**. Request re-implementation including the findings, then re-review after correction |
| **Critical** | D (Spec non-conformance), F (Design conformance violation) | **Report to user** and request a decision. Deviations from the design require revision of design.md and cannot be changed unilaterally by the implementer |

### Review Observation Log (レビュー観察ログ)

レビュー中に確認したすべての事項を記録する。自動修正した Minor 含め、レビューの透明性を確保するために **必須**。

各カテゴリ (A-F) について、以下のいずれかを記録する:
- **finding**: 問題を発見した（severity + 詳細）
- **auto-fixed**: Minor 問題を自動修正した（何を修正したか記録）
- **checked-ok**: 確認したが問題なし（**何を確認したか具体的に記載**）

⛔ 「問題なし」だけの記録は不十分。具体的に何を確認したかを記載すること。

例:
```
observations:
  - A: checked-ok — 命名規則を確認、`create_user` / `UserDto` 等の命名はプロジェクト規約に準拠
  - B: auto-fixed — `unwrap()` を `map_err()` に修正 (src/handler.rs:45)
  - C: checked-ok — SQL はクエリビルダー経由、外部入力のバリデーションあり、レスポンスに内部IDなし
  - D: checked-ok — Success 基準3項目: (1) ユーザー作成API ✓ (2) バリデーション ✓ (3) 重複チェック ✓
  - E: checked-ok — テストが実装と同期、具体値の検証あり（is_ok()だけでない）
  - F: checked-ok — design.md 定義外のフィールド/エンドポイント追加なし
```

### Report Format for Sending Back

When sending back to parallel-worker, return a findings report containing the following:

```
review_action: rework
findings:
  - category: B|C|E|E2
    severity: medium
    file: <target file>
    line: <line number or range>
    issue: <what the problem is>
    expected: <what it should be>
    rule_ref: <relevant rule file (e.g., security.md#A3)>
```

### Report Format for User Escalation

```
review_action: escalate
findings:
  - category: D
    severity: high
    issue: <description of the spec non-conformance>
    prompt_success_criteria: <the Success criteria that was checked>
    question: <items to confirm with the user>
```

### Limit on Re-reviews

- The send-back → re-review cycle is limited to a **maximum of 3 times**
- If not resolved after 3 cycles, escalate to the user with the remaining findings attached

## Phase Review Context (PhaseReview tasks only)

Phase Review（PhaseReview タスク）のコンテキストで呼び出された場合、通常の品質チェック・コードレビューに加えて、オーケストレーターから渡された **統合検証結果** を確認する。

### 統合検証結果の確認

オーケストレーターのプロンプトに含まれる統合検証結果（ビルド / 統合テスト / スモークテスト）を確認する:

| 統合検証結果 | アクション |
|-------------|----------|
| 全ステップ `pass` | 通常のレビューフローを続行 |
| いずれかが `fail` | `review_action: rework` を返す。findings に統合検証の失敗内容を含める |
| 一部 `skip`（`fail` なし） | 通常のレビューフローを続行。`skip` された検証項目をレポートの Notes に記載 |

### 完了レポートへの追加

Phase Review の場合、完了レポートに以下のキーを追加する:

```
- integration-verification:
    - build: pass|fail|skip
    - integration-tests: pass|fail|skip
    - smoke-test: pass|fail|skip
```

## Commit

Commit only when all aspects have passed. Do not commit while any findings remain.

```bash
git add <changed files>
git commit -m "<scope>: <summary of changes>"
```

## Completion Report Format (must include the following keys)

```
- worktree_path: <path>
- branch: <branch>
- tests: pass|fail <details>
- rustfmt: pass|fail
- clippy: pass|fail
- review: pass|fail
- review_action: commit|rework|escalate
- review_details:
    - style: pass|fail
    - design: pass|fail
    - security: pass|fail
    - spec_compliance: pass|fail
    - test_quality: pass|fail
    - tdd_compliance: pass|fail
    - design_conformance: pass|fail
- observations: <レビュー観察ログ — 全カテゴリ (A-F) の確認結果を review_action に関係なく常に記録>
- auto_fixed: <自動修正した Minor 問題のリスト (0件でも空リスト [] として記載)>
- integration-verification: <PhaseReview のみ必須。通常タスクレビューでは省略>
    - build: pass|fail|skip
    - integration-tests: pass|fail|skip
    - smoke-test: pass|fail|skip
- observations_summary: "<N> 項目確認、<M> 件 auto-fixed、<K> 件 finding"
- findings: <list of findings (rework/escalate の場合のみ)>
- commit: <hash (only for commit)>
- changed_files: <list>
```

## Agent Teams Rules

- Use **TaskGet** to check the details of the task assigned to you
- **Do not update task status to `completed`** — status management is the sole responsibility of the orchestrator (spec-implement Step 8). Only report your review results
- Report results to the leader via **SendMessage**
- On error, report the error via SendMessage (do not update task status)
