EdwardAngert · Claude · EdwardAngert · commit 2760742fe9d6 · 2025-04-23T15:49:04.000-04:00
- Use tj-actions/changed-files to get only modified markdown files - Pass only changed files to Vale action instead of entire docs directory - Fix performance issue causing Vale to run for 20+ minutes - Skip Vale check if no markdown files have changed 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
