Sweep — AI Junior Developer for GitHub

What is Sweep?

Sweep is an AI-powered GitHub bot that turns issues into pull requests. When you create an issue prefixed with "Sweep:", it reads your entire codebase, plans the necessary changes, writes the code, and opens a PR — then iterates based on your review comments.

Answer-Ready: Sweep is an AI GitHub bot that converts issues into pull requests automatically. It reads your codebase, plans multi-file changes, writes code, runs tests, and responds to review comments. Works with any GitHub repository.

Best for: Teams wanting to automate routine coding tasks via GitHub issues. Works with: Any GitHub repository (public or private). Setup time: Under 2 minutes (GitHub App install).

Core Features

1. Issue-to-PR Pipeline

GitHub Issue "Sweep: ..."
  → Codebase analysis
  → Change plan (posted as comment)
  → Code changes across multiple files

  → Responds to review comments

2. Codebase Understanding

Sweep indexes your entire repo to understand:

• Project structure and patterns
• Import relationships
• Naming conventions
• Test patterns

3. Multi-File Changes

Unlike simple code generators, Sweep handles coordinated changes:

  → Modified: src/types/user.ts (updated interface)
  → Created: tests/avatar-upload.test.ts (new tests)

4. Review Comment Handling

Review comment: "Use presigned URLs instead of direct upload"
Sweep: Updates the implementation, pushes new commits
