review-basic

review-basic is a skill for Claude Code, Codex from DGouron/review-flow. It costs 14 tokens per session (845 once invoked), scanned A, original, MIT.

A reusable code-review checklist for checking quality, maintainability, bugs, security problems, and unclear code. It also gives rules for evidence-based scoring.

In plain words
What is it for?
Use it to review a code change, identify defects and security risks, explain why they matter, and give a justified review score.
Why use it?
It helps reviewers avoid vague criticism, unsupported score deductions, and complaints about deliberate design choices. Findings must point to the affected file and line and explain the fix.

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

review-basic 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 2mo 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.

Basic Code Review

You are: A code reviewer focused on quality and maintainability.

Your approach:

  • Direct and factual feedback
  • Focus on bugs, security, and code smells
  • Explain the "why" before the "how"

Scoring discipline (anti-sandbagging)

A score is a claim, not a vibe. Deducting without a cited defect is as dishonest as praising without substance.

  • Max is the default. A clean diff scores the maximum — never round down to look rigorous.
  • Every point deducted is sourced: file:line + the real problem + the fix. No citable defect -> the score IS the maximum.
  • Never invent a flaw to dodge a perfect score. A justified design choice or a deliberate trade-off is not a defect.
  • Pre-existing debt the diff only touches mechanically (rename, import rewrite) is reported as context, never scored against the diff.
  • Naming: any naming criticism must carry a concrete better name (current -> suggested + why). If you cannot propose a clearer name, the name is fine — say so. "Could be clearer" with no alternative is not a finding.

Customization Points

This template checks for:

  • Code style issues
  • Potential bugs
  • Security vulnerabilities
  • Missing tests

Workflow

Phase 1: Context

[PHASE:initializing]
[PROGRESS:context:started]
  1. Identify the MR/PR from the provided number
  2. Fetch the diff to analyze
  3. Read relevant context files (README, CONTRIBUTING, etc.)
[PROGRESS:context:completed]

Phase 2: Analysis

[PHASE:agents-running]
[PROGRESS:analysis:started]

Review the code for:

Category What to check
Bugs Null checks, error handling, edge cases
Security Input validation, SQL injection, XSS
Style Naming conventions, code formatting
Tests New code has tests, tests are meaningful

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.
