code-review-advanced

code-review-advanced is a skill for Claude Code from jaktestowac/awesome-copilot-for-testers. It costs 99 tokens per session (1,818 once invoked), scanned A, original, MIT.

A guide for reviewing complex code changes using evidence from the code, tests, and system behavior. It looks beyond style to correctness, maintainability, security, performance, test quality, and operations.

In plain words
What is it for?
Auditing pull requests, legacy modules, authentication, payments, permissions, data flows, CI pipelines, test automation, refactors, and other changes that need a careful merge decision.
Why use it?
It helps uncover risks that a quick review may miss, especially in large pull requests, legacy code, sensitive features, or architectural refactors. Findings are tied to observable evidence and prioritised by risk.

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-advanced 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.

Advanced Code Review

Use this skill when a review needs to go beyond style feedback and surface the real engineering risks in a change. It is built for complex pull requests, sensitive code paths, test automation suites, and refactors where a shallow review would miss important trade-offs.

When to Use

Use this skill when the user asks for things like:

  • "review this PR critically"
  • "audit this change for maintainability or security"
  • "look for architectural issues, not just syntax problems"
  • "review this test automation code for flakiness and long-term cost"
  • "analyze whether this refactor is safe to merge"

Typical scenarios:

  • large or multi-file pull requests
  • legacy code audits
  • high-risk changes in authentication, payments, permissions, data flows, or CI pipelines
  • changes that add tests but may still reduce confidence
  • code that technically works but appears expensive to maintain

Review Principles

  • Evidence over intuition - every important finding should point to observable code, behavior, or missing coverage
  • Risk over volume - a few high-signal findings are better than a long list of cosmetic remarks
  • Context before judgment - understand intent, constraints, and surrounding patterns before recommending change
  • Severity must mean something - blockers and high-risk findings must be clearly separated from notes and polish
  • Actionable feedback only - explain why the issue matters and what the safer direction looks like
  • Acknowledge uncertainty - if the review lacks context, say so explicitly instead of pretending certainty

Review Workflow

Follow the phases in order.

Phase 0: Frame the review

Before reviewing, establish:

  • scope: whole repository, changed files only, or one subsystem
  • review goal: correctness, readiness, architecture, security, test quality, or debt discovery
  • change type: feature, bug fix, refactor, migration, test-only, or infrastructure
  • constraints: release pressure, backward compatibility, legacy boundaries, compliance needs

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.
