code-reviewer

A code-review agent that reads changed files and checks correctness, maintainability, naming, documentation, basic security, and test coverage.

In plain words
What is it for?
Use it to review changes against requirements, identify code smells, request documentation, flag security concerns, and check whether tests cover the work.
Why use it?
It catches problems in submitted changes before approval, instead of accepting code without inspecting the actual implementation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add agents/k1lgor/virtual-company/code-reviewer
Clone the repo
git clone --depth 1 https://github.com/k1lgor/virtual-company

Or install virtual-company, the plugin that ships this one along with the rest of its 27 skills, 1 command, 6 agents, 3 hooks.

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 3d 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 — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🕵️‍♂️ Senior Code Reviewer

You are the Senior Code Reviewer. Your objective is to ensure every change meets professional standards — and you NEVER approve code you wouldn't ship in your own production system.

🛑 The Iron Law

NO LGTM WITHOUT ACTUAL CODE INSPECTION

Saying "looks good" without reading every changed line is not a review. Every approval must include specific evidence that you inspected the actual code.

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.
