gerrit-mcp-server: Instructions file for Codex

AGENTS.md

gerrit-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from GerritCodeReview/gerrit-mcp-server. It costs 1,818 tokens per session, scanned A, original, Apache-2.0.

Project-specific instructions for a server that connects AI assistants to Gerrit, a code-review system. They describe its Python setup, dependency installation, and pytest testing rules.

In plain words
What is it for?
Use them when setting up the project, managing dependencies with uv, writing tests, or checking Gerrit server changes.
Why use it?
They prevent developers from using the wrong Python environment or inconsistent test structure, which can cause setup and test failures.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Gemini CLI.

This is GerritCodeReview/gerrit-mcp-server's own configuration. It tells Codex and OpenCode how to work on gerrit-mcp-server 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 gerrit-mcp-server 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

gerrit-mcp-server 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 1mo 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.

Gerrit MCP Server Development Guide

Overview

This document serves as the comprehensive guide for developing, testing, and maintaining the gerrit-mcp-server. It provides practical instructions for all stages of the development lifecycle.

Development Environment

Prerequisites

  • Python 3.12+
  • uv (the build script will install it via pip if absent)

Setup

The project uses uv for dependency management. uv.lock is committed to the repository to ensure reproducible installs.

  1. Run the build script:

    ./build-gerrit.sh
    

    This will create a virtual environment in .venv and install all dependencies (including dev extras) via uv sync.

  2. Activate the virtual environment:

    source .venv/bin/activate
    

[!IMPORTANT] ALWAYS use the virtual environment's Python. Never use the system Python.

Testing Standards

We use pytest as our testing framework.

Structure

  • Files: test_*.py
  • Functions: Descriptive names like test_query_changes_returns_results.
  • Pattern: Arrange, Act, Assert.

Fixtures

  • Use pytest fixtures for setup and dependency injection.
  • Place shared fixtures in conftest.py.
  • Use unittest.mock.patch as a context manager or fixture.

Running Tests

Run tests from the project root (no venv activation needed):

uv run pytest

Making any changes to source

If any changes to source are ever made, you must run uv run pytest to validate that the changes did not break any tests. Ask the user first after any changes are made.

Code Style

Use the /astral:ruff skill if available. Otherwise, to fix and format:

uv run ruff check --fix . && uv run ruff format .

To check without modifying: uv run ruff check . && uv run ruff format --check .

Documentation

User-facing documentation lives in the docs/ directory. Keep it in sync with code changes — docs are part of the deliverable, not an afterthought.

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.
