JevPR
A GitHub App that routes pull-request review work through Jev: it ingests the webhook, normalizes the PR context, gets a LOW, NORMAL or SPECIALIST decision, and a deterministic policy layer maps it to auto-approval, a review request or a check-run update.

Highlights
- Webhook in, decision out: Jev returns low, normal or specialist and policy maps it to approve, request review or update a check run.
- Policy can live in .github/jevpr.yml, controlling the action mapping and which GitHub reviewers may be assigned.
- Ships FastAPI endpoints, Celery workers, SQLAlchemy models and a docker compose stack with Postgres and Redis.
- Documented GitHub App permissions: checks write, contents read, issues and pull requests write, merge queues write.
- Apache-2.0 and under development; the README notes Jev is an AI model and can make mistakes.
Quickstart
bash
docker compose up -d --buildWatch out
Grounded on the repository README and GitHub metadata captured 2026-10-15; the README publishes no accuracy or false-approval figures, so the safety of the default policy cannot be judged from it. The project's own status note says it is under development and can contain bugs.
Questions about this entry
Short answers drawn from the linked project or page.
It is a GitHub App that routes pull-request review work using Jev as the decision engine. When a pull request is opened or updated, it ingests the webhook, normalizes the context, sends it to Jev and receives a structured decision such as LOW, NORMAL or SPECIALIST.
A deterministic policy layer maps the decision to an action like auto-approval, a request for review, or a check-run update. The decision model and the action policy are separate, so what the app does stays deterministic.
Runtime settings load from environment variables and an optional YAML file at .github/jevpr.yml. The YAML controls both the action mapping and the GitHub reviewers that may be assigned by policy; if the file is not present, a default policy is used.
For local development, create a virtual environment, install the package in editable mode with dev dependencies, and run uvicorn JevPR.main:app --reload. The README highly recommends Docker: docker compose up -d --build starts the API, worker, PostgreSQL and Redis.
The documented set is Checks read and write, Contents read, Issues read and write, Merge queues read and write, and Pull requests read and write.
FastAPI for the API layer, Celery workers for asynchronous GitHub work, SQLAlchemy and PostgreSQL for storage, Redis for the queue, and a providers boundary that isolates Jev behind a single interface.
The README says the project is under development and can contain bugs, and reminds readers that Jev is an AI model that can make mistakes. It is Apache-2.0 licensed.
