code-review-expert

code-review-expert is a skill for Claude Code from rocky2431/ultra-builder-pro. It costs 32 tokens per session (932 once invoked), scanned A, original, MIT.

A structured checklist for reviewing code. It covers design principles, security, speed, edge cases, and whether old code should be removed, and labels findings by severity.

In plain words
What is it for?
Use it when reviewing changes, especially large or mixed-purpose diffs, to check architecture, behavior, security, and maintainability.
Why use it?
It gives reviewers a consistent way to identify problems and decide which issues must block a merge.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-review-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Code Review Expert Checklists

Provides structured review workflow and reference checklists for the code-reviewer agent.

Severity Levels

Level Name Description Action
P0 Critical Security vulnerability, data loss risk, correctness bug Must block merge
P1 High Logic error, significant SOLID violation, performance regression Should fix before merge
P2 Medium Code smell, maintainability concern, minor SOLID violation Fix in this PR or create follow-up
P3 Low Style, naming, minor suggestion Optional improvement

Review Workflow

Step 1: Preflight Context

  • Run git status -sb, git diff --stat, and git diff to scope changes
  • Use git diff --cached to include staged changes
  • If needed, use Grep to find related modules, usages, and contracts

Edge cases:

  • No changes: Inform user, ask if they want to review staged changes or a specific commit range
  • Large diff (>500 lines): Summarize by file first, then review in batches by module/feature area
  • Mixed concerns: Group findings by logical feature, not just file order

Step 2: SOLID + Architecture Smells

Load references/solid-checklist.md for detailed prompts.

Look for SRP/OCP/LSP/ISP/DIP violations and common code smells. When proposing refactor, explain why it improves cohesion/coupling. Non-trivial refactors get incremental plans, not large rewrites.

Step 3: Removal Candidates

Load references/removal-plan.md for template.

Identify unused, redundant, or feature-flagged-off code. Distinguish safe delete now vs defer with plan. Provide follow-up steps with concrete checkpoints.

Step 4: Security and Reliability

Load references/security-checklist.md for coverage.

Check injection, auth gaps, secrets, race conditions, crypto, supply chain. Call out both exploitability and impact.

Step 5: Code Quality

Load references/code-quality-checklist.md for coverage.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
