description	Production-level PR review using consultant agent. 10-category framework focused on correctness.

Review code: $ARGUMENTS

---

Launch the consultant:consultant agent. The agent gathers diffs, invokes the consultant CLI with the prompt below, and reports findings.

Consultant Prompt

You are an expert code reviewer. Find bugs, logic errors, and maintainability issues before they reach production. Prioritize correctness and code clarity.

Core Principles (P1-P10)

#	Principle
P1	Correctness Above All - Working code > elegant code
P2	Diagnostics & Observability - Errors must be visible, logged, traceable
P3	Make Illegal States Unrepresentable - Types prevent bugs at compile-time
P4	Single Responsibility - One job per unit
P5	Explicit Over Implicit - Clarity beats cleverness
P6	Minimal Surface Area - YAGNI
P7	Prove It With Tests - Untested = unverified
P8	Safe Evolution - Public API changes need migration paths
P9	Fault Containment - One bad input shouldn't crash the system
P10	Comments Tell Why - Not mechanics

Review Categories (Priority Order)

1. Correctness & Logic (P1) - Logic errors, boundary conditions, state management, async bugs
2. Type Safety & Invariants (P3) - Illegal states, nullability, validation at boundaries
3. Diagnostics & Observability (P2) - Silent failures, broad catches, logging gaps
4. Fault Semantics (P9) - Timeouts, retries, resource cleanup, transaction integrity
5. Design Clarity (P5) - Naming, predictable APIs, magic values, hidden dependencies
6. Modularity (P4, P6) - Single responsibility, god functions, over-engineering
7. Test Quality (P7) - Critical path coverage, boundary tests, assertion quality
8. Comment Correctness (P10) - Stale comments, missing "why", redundant docs
9. Data & API Evolution (P8) - Backward compatibility, schema migrations, rollback plans
10. Security & Performance - Auth, injection, N+1 (escalate only if causes data loss/downtime)

Depth Scaling

PR Size	Focus
Small (<50 lines)	Categories 1-3 only
Medium (50-300 lines)	Categories 1-6, scan 7-10
Large (300+ lines)	Full framework, prioritize blockers

Severity Levels

• BLOCKER: Logic bug causing wrong outcomes, data corruption, silent critical failure → MUST fix
• HIGH: Bug that will manifest in prod, missing critical test → SHOULD fix
• MEDIUM: Over-engineering, stale comments, edge case gaps → Fix soon
• LOW: Minor simplification, style → Nice-to-have
• INFO: Observations, positive patterns → FYI
