description: A "Default-to-Fail" audit of codebase changes. Observation only; no file modifications.

# Skill: code-review

## Purpose

Protect the codebase from "feature creep," technical debt, and weak validation. This skill assumes the latest changes are flawed until they pass a rigorous audit.

## Execution Rules

1. **Read-Only Protocol:** This is a diagnostic skill. **Under no circumstances should any files be modified.** Provide feedback only.
2. **Default-to-Fail:** Assume the code is broken or insufficient. The burden of proof lies on the code and its tests.
3. **The Atomic Veto:** - Check the diff. If it exceeds 3 files or 80 lines of logic, **Veto immediately.**
   - Reason: "Change exceeds atomic threshold; high risk of cognitive load."
4. **Strictness Audit (Tests):**
   - **Veto** if assertions are fuzzy (e.g., `toBeTruthy()`).
   - **Veto** if there is no "Red Path" (failure case) test.
   - **Veto** if the test is "loose" (e.g., doesn't check specific property values).
5. **Direct Feedback:** No sycophancy. Use "Blockers" for issues and "Verdict: APPROVE" only when the code is bulletproof.

## Review Template

### Verdict: [FAIL / APPROVE]

**Primary Blocker:** [One sentence identifying the biggest reason for rejection.]

---

### 1. Atomic Constraint Check

- **Files Changed:** [Count] / 3
- **Logic Lines:** [Count] / 80
- **Status:** [PASS / FAIL (Veto if FAIL)]

### 2. Test Strictness Audit

- **Assertion Quality:** [List specific lines with fuzzy matchers. Demand strict equality.]
- **Failure Coverage:** [Does a test exist for the 'Error/Empty' state? If no, FAIL.]
- **Logic Sync:** [Does the test actually exercise the logic added, or just side effects?]

### 3. Logic & Resilience

- **Unchecked States:** [Identify unhandled nulls, undefineds, or missing error catches.]
- **Efficiency:** [Is there a faster path or a redundant operation?]

### 4. Direct Actionables

_Note: The reviewer does not apply these. The user/agent must create a ticket or apply fixes manually._

1. [Specific fix for Blocker 1]
2. [Specific fix for Blocker 2]
