code-review is a skill for Claude Code, OpenCode from TraftG/opencode-game-studio. It costs 41 tokens per session (603 once invoked), scanned A, original, MIT.

An architectural and quality review of selected source files. It checks project coding standards, structure, dependency direction, object-oriented design principles, testability, and performance concerns.

In plain words
What is it for?
Use it to review game engine, gameplay, AI, networking, UI, or tools code for complexity, dependencies, interfaces, documentation, and architectural consistency.
Why use it?
It identifies maintainability and design problems before they spread to other parts of the codebase.

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 1mo 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.

What it actually says

When this skill is invoked:

  1. Read the target file(s) in full.

  2. Read the OPENCODE.md for project coding standards.

  3. Identify the system category (engine, gameplay, AI, networking, UI, tools) and apply category-specific standards.

  4. Evaluate against coding standards:

    • 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)
  5. Check architectural compliance:

    • Correct dependency direction (engine <- gameplay, not reverse)
    • No circular dependencies between modules
    • Proper layer separation (UI does not own game state)
    • Events/signals used for cross-system communication
    • Consistent with established patterns in the codebase
  6. Check SOLID compliance:

    • Single Responsibility: Each class has one reason to change
    • Open/Closed: Extendable without modification
    • Liskov Substitution: Subtypes substitutable for base types
    • Interface Segregation: No fat interfaces
    • Dependency Inversion: Depends on abstractions, not concretions
  7. Check for common game development issues:

    • Frame-rate independence (delta time usage)
    • No allocations in hot paths (update loops)
    • Proper null/empty state handling
    • Thread safety where required
    • Resource cleanup (no leaks)
  8. Output the review in this format:

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.
