PR Reviewer Labeler

A GitHub Action that automatically labels pull requests with the ideal number of reviewers based on the size and complexity of changes.

Features

• Size-based reviewer recommendations: configurable thresholds mapping lines changed to reviewer count
• File-type weighting: weight certain file types higher or lower (e.g., tests count less, core code counts more)
• PR labels: automatically applies labels like reviewers: 2
• PR comments: posts a summary table with the recommendation
• Idempotent: updates existing labels and comments instead of creating duplicates

Quick Start

Install from the GitHub Marketplace, or add directly to your workflow:

- uses: anistark/pr-reviewer-labeler@v1

With zero configuration, it uses sensible defaults based on lines changed to determine the suggested number of reviewers.
