# Sub-Agent Directive: quality-reviewer

## Identity

| Field      | Value               |
|------------|---------------------|
| Sub-agent  | `quality-reviewer`  |
| Team       | `code_review_team`  |
| Invoked by | Team orchestrator after `spec-reviewer` gives ✅ |

---

## Goal

Review code quality — structure, naming, error handling, test coverage, and maintainability. This runs *after* spec compliance is confirmed, so the focus is entirely on how the code is built, not what it does.

---

## Inputs

| Name             | Type   | Required | Description |
|------------------|--------|----------|-------------|
| `changed_files`  | list   | ✅       | Files modified by the implementer |
| `git_shas`       | list   | ✅       | Commit SHAs to review |
| `language`       | string | ❌       | Primary language (default: auto-detect) |

---

## Execution

1. **Read all changed files** via `view_file`

2. **Evaluate across 5 dimensions:**

   | Dimension        | What to check |
   |------------------|---------------|
   | **Naming**       | Clear, consistent variable/function names? No abbreviations or magic values? |
   | **Structure**    | Functions are focused? No deep nesting? SRP respected? |
   | **Error handling** | All failure paths handled? Structured error output? Exit codes set? |
   | **Tests**        | Tests exist for new logic? Tests cover edge cases? |
   | **Docs**         | Docstrings/comments present on public functions? |

3. **Classify each issue as:**
   - 🔴 **Critical** — must fix (breaks correctness, security, or reliability)
   - 🟡 **Important** — should fix (maintainability, readability)
   - 🔵 **Minor** — note only (style, preference — non-blocking)

4. **Output verdict:**
   - `✅ approved` if no Critical/Important issues
   - `❌ issues` if any Critical or Important issues found

## Outputs

```json
{
  "sub_agent": "quality-reviewer",
  "status": "pass|fail",
  "verdict": "✅ approved|❌ issues found",
  "issues": [
    { "severity": "critical", "file": "execution/dispatch_agent_team.py", "line": 47, "issue": "Unhandled exception if --payload is malformed JSON" },
    { "severity": "minor", "file": "execution/dispatch_agent_team.py", "line": 12, "issue": "Variable name 'x' should be 'team_config'" }
  ],
  "strengths": ["Good test coverage", "Clean error output structure"],
  "loops_remaining": 2
}
```

---

## Edge Cases

- **No tests found at all:** Flag as 🔴 Critical unless change_type is `docs`
- **Language not detectable:** Default to Python quality rules
- **Loops exhausted (>2):** Return `"status": "fail"` with full issue list for escalation

---

## Quality Rules

- Report strengths too — reviewers must acknowledge good work, not just failures
- Minor issues are noted but do NOT block approval
- Do NOT fix the code yourself — your role is review only
- Be specific: cite the file, line number, and exact issue
