Additional Information

The built dist/daemon.mjs has duplicate imports:

• Line 1: import { createRequire } from 'module';
• Line 13: import { createRequire } from "module"; (duplicate)

This causes Node.js to reject the module as invalid. The issue appears to be in the build tooling (likely esbuild or tsx configuration) that generates the daemon bundle.

Attempted Fixes

• ✅ npm install in the skill directory
• ✅ npm run build to rebuild the daemon
• ✅ Both .claude and .agents skill directories exhibit the same issue
• ❌ Manual removal of duplicate imports didn't fully resolve the underlying build problem
