File Watcher Skill

Overview

Sets up a file watcher using chokidar that monitors a path for changes and runs a Claude prompt against every changed file. The prompt supports a {{file}} placeholder that gets replaced with the changed file path.

Quick Start

# Watch src/ and analyze any changed file
node scripts/watch-files.mjs ./src 'Analyze {{file}} for issues'

# Watch only .tsx files with 1s debounce
node scripts/watch-files.mjs ./src 'Review {{file}} for React best practices' --glob '*.tsx' --debounce 1000

# Via package.json script (pass args after --)
bun run watch:files -- ./src 'Check {{file}}'
