Show DEV: prx - Local-first PR review: AI informs, human decides
Description and use
prx is a local-first tool that automatically generates pull‑request reviews, giving developers a brief, findings, and verdict before opening a PR.
Problem
Pull request reviews pile up; the slow part is switching context and locating key changes, causing loss of workflow continuity.
Outcome
prx provides a local, read‑only automated review that surfaces key information before the reviewer opens a PR, reducing context switching and preserving workflow continuity.
Workflow
- 1. Install prx and a coding-agent CLI (claude, codex, or pi) or provide an LLM API key.
- 2. Run the prx daemon; it polls selected GitHub repositories via the local gh session.
- 3. For each open PR, prx invokes the agent or API with the diff and prompt.
- 4. The agent returns a review containing a brief, findings, and verdict.
- 5. The reviewer views the review in the macOS menu bar or via
prx status/prx briefin terminal. - 6. If desired, the reviewer can approve, merge, or request changes directly from the review, or use
prx review --dry-runto preview without posting.
Evidence
Pull request reviews pile up. For me the slow part was never the reading. It was the switch: opening a PR cold, working out what it was for, and finding the few things in it that mattered.
prx runs on your machine. A background daemon polls the GitHub repositories you choose. For each open pull request it runs a coding-agent CLI you already have installed (claude, codex or pi), or calls an LLM API, and gets back a review.
When I sit down to review, each PR already has: a brief: a few plain sentences on what the PR changes and what to notice, findings, each marked blocking or nit, a one-line verdict.
Local-first describes prx: the daemon, its state and its history are on your disk, there is no server of mine in the middle, and there is no telemetry.
