reviewing-code is a skill for Claude Code from bostonaholic/rpikit. It costs 44 tokens per session (1,641 once invoked), scanned A, original, MIT.

A method for reviewing code changes for correctness, design quality, and maintainability.

In plain words
What is it for?
Use it to review pull requests or implementation diffs, especially changes involving APIs, dependencies, migrations, or architecture.
Why use it?
It gives reviewers a consistent order for understanding the change, finding edge cases, and writing clear, actionable feedback.

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

reviewing-code 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 8d 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 Methodology

Deep code reviews that protect architecture, catch correctness issues, and provide mentoring-quality feedback using Conventional Comments.

Purpose

This skill provides methodology for reviewing code changes introduced during implementation. Unlike full codebase audits, this focuses on the delta - what was added or modified - to catch quality issues before they're committed.

Review Workflow

Follow this order - don't jump to nits.

1. Understand Context

  • What problem is this solving?
  • Is there a linked ticket/design doc?
  • Read the implementation plan if available

2. Scan High Level

  • Files/directories touched
  • New public APIs or endpoints
  • New dependencies
  • Migrations and data changes
  • Size check: 200-400 lines optimal, >1000 recommend splitting

3. Evaluate Correctness

  • Does it solve the described problem?
  • Edge cases and error conditions handled?
  • Assumptions explicit?
  • Race conditions considered?

4. Evaluate Design

  • Aligns with existing architecture?
  • New pattern where existing one would work?
  • Local change or architecture decision in disguise?

Pattern Recognition:

Smell Pattern to Suggest
Long method Compose Method
Type-based conditionals Replace Conditional with Polymorphism
Duplicate algorithm structure Form Template Method
Scattered null checks Introduce Null Object
Type field drives behavior Replace Type Code with State/Strategy

Always name patterns explicitly.

SOLID Quick Check:

Principle Red Flag
SRP Class has multiple unrelated responsibilities
OCP Must modify existing code to add behavior
LSP Subclass changes expected behavior
ISP Fat interface forces unused dependencies
DIP High-level depends on low-level details

5. Evaluate Tests

  • Tests for critical paths and edge cases?
  • Tests read like specifications?
  • Stable, isolated, fast?

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.
