Your PRs, from 🥚 to 🍗 — reviewed by an AI that pecks through the diff.
Peck is a lightweight macOS menu-bar app that watches your GitHub pull requests and reviews them with an AI agent. Native SwiftUI — no Electron, no server, no account. Just a chick living in your menu bar.
Left: your PRs hatching toward approval. Right: agent-drafted reviews, one click to post.
🔍 An agent reviews for you. The moment someone requests your review, Peck reads the PR and drafts a plain-language explanation plus a recommended verdict — Approve, Request changes, or Comment — with a ready-to-post body. You confirm with one click.
🔑 No API key required. Peck runs the review through your existing claude (Claude Code) or codex (ChatGPT) CLI login. Prefer an Anthropic key? That works too.
🥚→🐔 Your PRs, gamified. Every PR you open is a quest: it hatches 🥚 → 🐣 → 🐔 → 🍗 as approvals roll in. Approved but blocked by a merge conflict? It gets flagged in orange so nothing silently stalls.
📊 One glance, two numbers. The menu bar shows how many of your PRs need action and how many are waiting on your review — no tab-switching.
🔔 Notified at the right moment — a new review request, a conflict on an approved PR, or "everything's approved 🎉".
🧩 Your rules, not a black box. Teach the agent how you review by dropping in markdown skill files — enforce team conventions, demand tests, focus on security, ban an anti-pattern, set the tone. Peck folds every enabled skill straight into the agent's instructions, so reviews match your standards instead of generic feedback. Add or edit them anytime in ~/Library/Application Support/PRAgent/skills/ — no rebuild needed.
🔒 Native & private. A tiny SwiftUI app (no Electron), with your tokens kept in the macOS Keychain — never in a file. UI in English or 한국어.
