code-reviewer

A code-review helper that checks code changes for bugs, security weaknesses, quality problems, and compliance with coding standards.

In plain words
What is it for?
Use it to review pull requests, audit new code for security issues, or check whether code follows a style guide.
Why use it?
It helps find problems in a pull request—a proposed set of code changes—before they are merged or released.

Agent

Part of the claude plugin — 17 agents, 1 MCP server shipped together

Install

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.

agentmods
npx agentmods add agents/josstei/maestro-orchestrate/code-reviewer
Clone the repo
git clone --depth 1 https://github.com/josstei/maestro-orchestrate

Or install claude, the plugin that ships this one along with the rest of its 17 agents, 1 MCP server.

Per session 207 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 293 The whole file, excluding the scripts and references it only reads on demand.

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.

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.

code-reviewer is an agent published in the GitHub repository josstei/maestro-orchestrate (459 stars, last pushed 26d ago), licensed Apache-2.0. It adds 207 tokens to every session and 293 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings.
