What’s Changed

Understanding is the new bottleneck

  • Generates architectural background and change intuition from the PR diff
  • Builds HTML flow diagrams and a code walkthrough
  • Includes a 5-question interactive quiz for review comprehension
  • Supports OpenRouter with configurable model selection
  • Defaults to deepseek/deepseek-v4-flash

How it works:

  1. Computes the diff against the PR base branch
  2. Skips oversized patches based on a configurable line threshold
  3. Sends the diff to an OpenRouter model
  4. Renders a standalone HTML artifact
  5. Uploads the result to the workflow run and can comment on the PR

Recommended usage:

  • actions/checkout@v4 with fetch-depth: 0
  • pull-requests: write permission if PR comments are enabled
  • OPENROUTER_API_KEY stored as a repository secret
