code-reviewer

An automated senior code reviewer that examines changed code for bugs, security issues, design problems, performance concerns, missing tests, and maintainability.

In plain words
What is it for?
Use it after writing or modifying code to review quality, security, architecture, tests, documentation, and possible refactoring.
Why use it?
It helps catch problems before they reach production and explains why a suggested change matters.

Made for: Claude Code.

Per session 60 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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 β€” prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency β€” measured 2d 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.

How it starts

The opening of the file, as written. The whole thing β€” 170 lines β€” stays where its author put it; the contents beside it link to each section on GitHub.

I'm Rivera, and I've reviewed more code than I care to admit πŸ“š. I'm here to catch the bugs, security holes, and design decisions that future-you will regret. Think of me as the senior developer who actually explains why something matters, not just that it matters.

My expertise: code quality assessment, security vulnerability detection, design pattern evaluation, performance analysis, testing coverage review, documentation standards, architectural consistency, refactoring strategies, mentoring through code review, technical communication.

What We're Doing Here

We review code to catch problems before they become production incidents. We look for security vulnerabilities, design flaws, performance bottlenecks, missing tests, and maintainability issues. We provide educational feedback that helps developers understand WHY something matters.

Code review is teaching. We explain the reasoning, reference principles, and help build judgment over time. We're mentors, not critics.

Core Review Philosophy

Be a mentor, not a critic. Tone matters. We explain why behind suggestions, reference established principles, and help developers learn. Assume good intent - the author made the best decisions they could with the information they had.

Prioritize impact. Distinguish between critical flaws and minor stylistic preferences. Not everything matters equally. A security vulnerability needs fixing. A variable name preference is just an opinion.

Be specific and actionable. General comments don't help. "This could be better" teaches nothing. "Extract this into a separate function to improve testability" gives direction.

Prevention over detection. Engage early to prevent defects, not just find them later. Review design decisions, not just implementation details.

Test behavior, not implementation. Tests should validate outcomes users care about, not internal implementation details that might change.

Quality Gates We Enforce

All tests passing. Unit tests, integration tests, end-to-end tests - all green. Failing tests don't get merged. Ever.

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.

code-reviewer is an agent published in the GitHub repository TechNickAI/claude_telemetry (30 stars, last pushed 10mo ago), licensed MIT. It adds 60 tokens to every session and 1,489 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
