reviewer-mcp: Instructions file for Codex

AGENTS.md

reviewer-mcp AGENTS.md is an instructions file for Codex, OpenCode from kodaimaehata/reviewer-mcp. It costs 630 tokens per session, scanned A, original, MIT.

Repository instructions for the reviewer-mcp project, a TypeScript server that uses Cursor to create code reviews. They document the project layout, commands, coding style, and testing rules.

In plain words
What is it for?
Use them when developing, building, testing, or reviewing changes in the reviewer-mcp repository.
Why use it?
They give an agent the project-specific rules needed to make changes consistently and run the right checks.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is kodaimaehata/reviewer-mcp's own configuration. It tells Codex and OpenCode how to work on reviewer-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything reviewer-mcp configures →

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

reviewer-mcp AGENTS.md 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 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.

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.

Repository Guidelines

Project Structure & Module Organization

  • src/: TypeScript sources.
    • server.ts: MCP stdio server exposing cursor.review.
    • cursor.ts: calls cursor-agent, parses JSON, saves to reviews/.
    • prompt/ and schemas/: prompt template and input JSON schema.
  • bin/: CLI entrypoints.
    • cursor-reviewer-mcp: runs built server from dist/.
    • cursor-agent: local stub of Cursor CLI for dev.
  • dist/: compiled JS + copied assets (via scripts/copy-assets.mjs).
  • reviews/: timestamped review JSON logs.

Build, Test, and Development Commands

  • nvm use && npm i: ensure Node 22 and install deps.
  • npm run build: compile TypeScript and copy assets to dist/.
  • npm run dev: run server with tsx (no build). Tip: PATH=$(pwd)/bin:$PATH npm run dev uses the local cursor-agent stub.
  • npm start: run built server (node dist/server.js).
  • npm run typecheck: strict TS checks without emit.

Coding Style & Naming Conventions

  • Language: TypeScript (ESM), Node >=22 <23, strict mode on.
  • Indent 2 spaces; keep semicolons; prefer named exports.
  • Files: lowercase; hyphenate multi-word scripts (e.g., copy-assets.mjs); types/interfaces PascalCase, vars/functions camelCase.
  • Keep schemas and prompt deterministic; update both src/ and built assets via npm run build.

Testing Guidelines

  • No test framework is configured. Validate locally with the stub:
    • PATH=$(pwd)/bin:$PATH npm run dev then connect via your MCP client (e.g., Claude Code) or invoke the tool flow defined in .claude/agents/.
  • If introducing tests, prefer vitest with *.spec.ts under src/; include basic parsing/error-path coverage for cursor.ts.

Commit & Pull Request Guidelines

  • Use Conventional Commits: feat(cursor-reviewer): ..., fix(cursor): ..., chore: ....
  • PRs must include: purpose (what/why), summary of changes, validation steps (commands/output), and any schema/prompt or env var changes.
  • Link related issues; attach sample review JSON when relevant.
  • Run npm run typecheck && npm run build before requesting review; keep diffs minimal and focused.

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.
