PRaline

An interactive CLI that reviews your GitHub pull requests with Claude Code as the LLM backend — no API key needed, it rides your existing Claude Code subscription.

Disclaimer: This is fully vibe-coded

What it does

• Builds a lightweight knowledge base of a repo (architecture, conventions, past PR lessons)
• Picks an open PR and reviews its diff, aware of the existing comment thread
• Walks you through each proposed comment — accept, reject, or edit — before posting anything
• Never touches code: read-only on contents, comment/issue-only on GitHub

Quickstart

No need to clone this repo — uv can run PRaline straight from GitHub:

# 1. cd into the repo you want to review
cd ~/src/some-code-repo

# 2. set your GitHub token (see Requirements below for scopes)
export GITHUB_TOKEN=github_pat_...

# 3. start reviewing PRs of the current repo
uvx --from git+https://github.com/ameroyer/PRaline praline

Add --model opus (default: sonnet) or --dir /path/to/repo to review a repo other than the current directory.

Note: this works as-is once the repo is public. While it is private, authenticate the clone with your token instead: uvx --from git+https://${GITHUB_TOKEN}@github.com/ameroyer/PRaline praline

Requirements

• Python >= 3.12
• claude CLI installed and logged in
• A GitHub personal access token stored in GITHUB_TOKEN or GH_TOKEN, scoped to:
  • Contents: read-only
  • Pull requests: read/write
  • Issues: read/write

Usage (from a local clone)

uv run --project /path/to/praline praline --dir ~/src/some-code-repo --model opus

Then follow the CLI menu: build the knowledge base (can be pushed as a Claude Artifact later) or pick a PR to review comment by comment.

Auto mode

praline auto reviews PRs unattended: no approval loop, every proposed comment is posted straight away.

uvx --from git+https://github.com/ameroyer/PRaline praline auto
uvx --from git+https://github.com/ameroyer/PRaline praline auto 123 456

• Scans open PRs, skipping drafts, and only reviews ones with new activity (a new commit, comment, or review) since you last auto-reviewed them.
• PR numbers passed as arguments are always reviewed, draft or not, activity or not.
• Before reviewing, it prints the total changed-file count across all selected PRs. Past --max-changed-files (default 500) it asks for a one-time confirmation; everything else runs unattended.
• Ends with a per-PR summary: files changed, comments added, replies left, threads resolved.

Last-reviewed timestamps are stored per PR in .praline/auto_state.json inside the target repo.
