Workflow
Step 1: Detect Project Type
Scan for project indicators to determine the appropriate organisation approach:
- Frontend SPA / Next.js / React → feature-based
- Backend API / Express / Fastify / Hono → layer-based
- Monorepo (apps/ + packages/) → hybrid
- Existing structure → respect and extend current patterns
Step 2: Audit
Check the existing structure against all rules. Report violations grouped by severity with directory paths.
Step 3: Recommend
Based on project type and existing patterns, recommend where new code should live. Always prioritise colocation.
