pullwise 0.3.0

AI-powered PR descriptions, labels, and code review using OpenAI

PullWise ✈️

Stop writing PR descriptions. Let AI do it.

📦 GitHub Action: albertusreza/pr-pilot · PyPI: pullwise

pr-pilot is a GitHub Action + CLI that analyzes your diff and commit history, then automatically writes a clear, structured PR description — with a summary, change list, test plan, and labels.

# .github/workflows/pr-description.yml
- uses: albertusreza/pr-pilot@main
  with:
    openai-api-key: ${{ secrets.OPENAI_API_KEY }}

That's it. Every new PR gets a description like this:

---

Add rate limiting to upload endpoint

Summary

Adds per-IP rate limiting to /api/upload using a sliding window algorithm. Without this, a single client could saturate the server with concurrent uploads.

Changes

• Add RateLimiter middleware with configurable window and max requests
• Apply limiter to /api/upload route (100 req/min default)
• Return 429 Too Many Requests with Retry-After header
• Add unit tests for edge cases (burst, reset, concurrent)

Test Plan

1. Run pytest tests/test_rate_limiter.py
2. Send 101 rapid requests to /api/upload — 101st should return 429
3. Wait 60 seconds — requests should succeed again

Labels: feature, security

Auto-comment on every PR (GitHub Action)

# .github/workflows/pr-review.yml
- uses: actions/checkout@v4
  with:
    fetch-depth: 0
- run: pip install pullwise
- run: pr-pilot comment --repo ${{ github.repository }} --pr ${{ github.event.pull_request.number }}
  env:
    OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}
    GITHUB_TOKEN: ${{ github.token }}

The comment updates itself on every new push — no duplicate comments.

Options

Input	Default	Description
openai-api-key	—	Required. Your OpenAI API key
model	gpt-4o	OpenAI model to use
skip-labels	false	Skip adding labels to the PR
update-title	false	Also rewrite the PR title

How it works

1. On PR open, checks out the branch with full history
2. Runs git diff <base>...HEAD to get the full diff
3. Collects commit messages with git log --oneline
4. Sends both to GPT-4o with a structured prompt
5. Parses the JSON response and updates the PR body + labels via GitHub API
6. Skips update if the PR already has a substantial description (>100 chars)

Why

Over 60% of PRs are merged with descriptions like "fix bug", "WIP", or nothing at all. This makes code review harder, changelogs meaningless, and git history useless for future maintainers.

pr-pilot takes 30 seconds to set up and runs on every PR automatically — no discipline required.

Cost

Each PR description costs roughly $0.01–0.03 with gpt-4o depending on diff size. For a team of 5 opening ~20 PRs/week, that's about $1–3/month.

Self-hosted / private repos

Works with private repos. Just add the secret and the workflow file — no data leaves your GitHub Actions runner except the diff sent to OpenAI.
