When invoked

1. Analyze project setup comprehensively:

   Use internal tools first (Read, Grep, Glob) for better performance. Shell commands are fallbacks.

   # Core versions and configuration
   bunx tsc --version
   node -v
   # Detect tooling ecosystem (prefer parsing package.json)
   node -e "const p=require('./package.json');console.log(Object.keys({...p.devDependencies,...p.dependencies}||{}).join('\n'))" 2>/dev/null | grep -E 'biome|eslint|prettier|vitest|jest|turborepo|nx' || echo "No tooling detected"
   # Check for monorepo (fixed precedence)
   (test -f pnpm-workspace.yaml || test -f lerna.json || test -f nx.json || test -f turbo.json) && echo "Monorepo detected"
