code-review

code-review is a skill for Claude Code, Codex from bullish0x/GameStudio. It costs 41 tokens per session (1,733 once invoked), scanned A, a copy of code-review, MIT.

A review of source code for design quality, maintainability, coding standards, tests, and performance. It can also compare the code with documented architecture decisions.

In plain words
What is it for?
Use it to review one file or a group of files before merging or while improving an existing system.
Why use it?
It helps identify code that is hard to maintain, inconsistent with project rules, difficult to test, or likely to cause performance problems.

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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phase 1: Load Target Files

Read the target file(s) in full. Read AGENTS.md for project coding standards.


Phase 2: Identify Engine Specialists

Read .agents/docs/technical-preferences.md, section ## Engine Specialists. Note:

  • The Primary specialist (used for architecture and broad engine concerns)
  • The Language/Code Specialist (used when reviewing the project's primary language files)
  • The Shader Specialist (used when reviewing shader files)
  • The UI Specialist (used when reviewing UI code)

If the section reads [TO BE CONFIGURED], no engine is pinned — skip engine specialist steps.


Phase 3: ADR Compliance Check

Argument: /code-review [file(s)] may optionally include a story file path as the last argument (e.g., /code-review src/combat/attack.gd production/epics/combat/story-001.md). If a story path is provided, read it to extract the governing ADR reference.

Search for ADR references in, in priority order:

  1. The story file (if provided as argument)
  2. Header comments at the top of the implementation files
  3. Commit messages referencing these files (git log --oneline -- [file])

Look for patterns like ADR-NNN or docs/architecture/ADR-.

If no ADR references found, note: "No ADR references found — ADR compliance check skipped. For full ADR compliance review, provide the story path: /code-review [files] [story-path]."

For each referenced ADR: read the file, extract the Decision and Consequences sections, then classify any deviation:

  • ARCHITECTURAL VIOLATION (BLOCKING): Uses a pattern explicitly rejected in the ADR
  • ADR DRIFT (WARNING): Meaningfully diverges from the chosen approach without using a forbidden pattern
  • MINOR DEVIATION (INFO): Small difference from ADR guidance that doesn't affect overall architecture

Phase 4: Standards Compliance

Identify the system category (engine, gameplay, AI, networking, UI, tools) and evaluate:

  • Public methods and classes have doc comments
  • Cyclomatic complexity under 10 per method
  • No method exceeds 40 lines (excluding data declarations)
  • Dependencies are injected (no static singletons for game state)
  • Configuration values loaded from data files
  • Systems expose interfaces (not concrete class dependencies)

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.
