Coding agent in your repo. Your models, agents & rules.
Jr-Arch is an open-source coding agent built to live inside your repository. Bring your own model and API key instead of being locked to a single provider. Agents, rules, personas, and guardrails are plain files in `.gitagent/`, making them readable, version-controlled, and reviewable. Built around the OpenGAP protocol, with support for major model providers and OpenAI-compatible endpoints, zero runtime dependencies, and no telemetry.
Jr-Arch is an open-source coding agent designed to integrate within repositories, allowing users to utilize their own models and API keys. It supports the OpenGAP protocol and major model providers, with all configurations stored in version-controlled files for easy review.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
