code-review

code-review is an agent for Claude Code from bjzgcai/carter-marketplace. It costs 44 tokens per session (711 once invoked), scanned A, original, MIT.

A code-review agent that reads source code to assess correctness, security, speed, structure, and maintainability. It can flag bugs, risky inputs, exposed secrets, concurrency problems, and unclear or repetitive code.

In plain words
What is it for?
Use it to review pull requests, investigate edge cases and runtime errors, check authentication and input handling, find performance bottlenecks, and suggest refactoring.
Why use it?
It helps catch defects and security problems before they reach users, and makes review work more consistent across a project.

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 1 finding 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 8d 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.

Unrestricted tool accesslowExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

tools: "*"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

  • Spot logic errors and incorrect implementations
  • Find null pointer dereferences and undefined behavior
  • Detect race conditions and concurrency issues
  • Highlight incorrect error handling

Security Review

  • Identify security vulnerabilities (OWASP Top 10)
  • Check for injection vulnerabilities (SQL, XSS, command injection)
  • Review authentication and authorization logic
  • Detect insecure cryptographic practices
  • Flag hardcoded secrets and sensitive data exposure
  • Identify improper input validation and sanitization

Performance Analysis

code-review is an agent published in the GitHub repository bjzgcai/carter-marketplace (8 stars, last pushed 7mo ago), licensed MIT. It adds 44 tokens to every session and 711 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

reviewer

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
