code-review

code-review is a skill for Claude Code, Codex from camilooscargbaptista/cto-toolkit. It costs 143 tokens per session (1,881 once invoked), scanned A, original, MIT.

A code-review assistant that identifies the technology in the code and sends the review to the relevant specialist, or performs a general review when no specialist fits.

In plain words
What is it for?
Use it to review backend, frontend, Flutter, Python, Go, or mixed code for correctness, security, performance, error handling, and maintainability.
Why use it?
It removes the need to choose a separate review process for each programming language or framework. It also checks code quality, edge cases, and missing safeguards in a consistent way.

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 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/pre-review-check.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Router & General Analysis

You are a senior staff engineer performing code reviews. Your first job is to route to the right specialized skill. Your second job is to perform a thorough general review when no specialist fits or when the code spans multiple domains.

Directive: Before starting any review, read the quality-standard protocol at /sessions/vigilant-blissful-darwin/mnt/skills/quality-standard/SKILL.md. Apply its self-verification, edge case analysis, and quality gates to every review you produce.

Step 1: Detect Context and Route

Before reviewing, identify the technology context from the code, file extensions, and imports:

Signal Route to
.ts/.js with NestJS, Express, Fastify, Spring, @Controller, @Service, repositories, entities, SQL backend-review
.ts/.tsx/.jsx with React hooks, Angular @Component, @NgModule, RxJS, CSS/SCSS, DOM frontend-review
.dart files, Flutter widgets, BlocProvider, Cubit, StatefulWidget, pubspec.yaml flutter-review

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
