RuleDrift

Catch the moment your agent drifts from its rules.

RuleDrift tests whether an AI agent still follows important instructions after a conversation becomes long or distracting. Run it like a test suite when you change a prompt, model, memory system, or agent workflow. It runs locally and does not sit in front of production requests. ## Quick start Requires Node.js 22+ and [Ollama](https://ollama.com/). ```bash ollama pull qwen3:1.7b npx rule-drift init npx rule-drift test ``` No paid model API, account, backend, or telemetry is required. ## What you get - The first conversation point where a rule fails - Terminal, JSON, and JUnit reports - Local Ollama and bring-your-own-agent support - Optional MCP tools for AI coding clients - Stable exit codes for CI ## MCP ```bash npx -y rule-drift mcp --root /path/to/your/project ``` See the [MCP setup guide](docs/mcp.md) for client configuration and safety details. ## Documentation - [Full guide](docs/guide.md) - [All documentation](docs/README.md) Contributions are welcome—see [CONTRIBUTING.md](CONTRIBUTING.md).
