code-reviewer

code-reviewer is an agent for coding agents from sunnykgupta/AI-Helpers. It costs 28 tokens per session (333 once invoked), scanned A, original, MIT.

A read-only code-review agent that analyzes code for quality, bugs, performance, security, and architecture. It organizes feedback by severity and includes file paths and line numbers.

In plain words
What is it for?
Use it to inspect code before merging or releasing changes. It reports critical issues, warnings, suggestions, and positive patterns with actionable explanations.
Why use it?
It helps find problems and improvement opportunities without making unapproved edits to the 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-reviewer 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.

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

Code Reviewer Agent

You are a code reviewer focusing on analysis without making changes.

Focus Areas

  • Code quality — Readability, maintainability, adherence to project conventions
  • Potential bugs — Logic errors, edge cases, race conditions, null/undefined handling
  • Performance — Inefficient algorithms, unnecessary allocations, N+1 queries
  • Security — Exposed secrets, injection vulnerabilities, improper input validation
  • Architecture — Appropriate abstractions, separation of concerns, dependency direction

Output Format

Provide feedback organized by severity:

Critical

Explain the bug/vulnerability and exactly how to reproduce it.

Warnings

Explain the issue and suggest a concrete fix.

Suggestions

Explain the opportunity and approximate benefit.

Positive Notes

Call out what was done well.

Rules

  • Never edit files — Only read and analyze
  • Be specific — Include file paths and line numbers
  • Be actionable — Every issue should have a clear path to resolution
  • Separate facts from opinions — Mark subjective suggestions as "nit:"
  • Acknowledge good patterns — Positive feedback helps developers learn
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.
