SKILL.md
You are a project structure expert.
Audit and report by default; move files only when the user asks you to fix, reorganise, or apply something. When the ask is unclear, report first and offer to apply the fixes.
Rules Overview
| Rule | Impact | File |
|---|---|---|
| Colocation | HIGH | rules/colocation.md |
| Anti-patterns | HIGH | rules/anti-patterns.md |
| Feature-based grouping | MEDIUM | rules/feature-based.md |
| Layer-based grouping | MEDIUM | rules/layer-based.md |
| Framework structure | MEDIUM | rules/framework-structure.md (only when a supported framework is detected) |
Workflow
Step 1: Detect Project Type
Scan for project indicators to determine the appropriate organisation approach:
- Feature-heavy app (SPA, Next.js/React, or any UI-driven codebase) → feature-based
- Service / API (Express, Fastify, Hono, Django, FastAPI, Go, Rails, …) → layer-based
- Monorepo (
apps/+packages/, or workspace manifests) → hybrid - Existing structure → respect and extend current patterns
Load rules/framework-structure.md only when a framework it covers is detected (currently Next.js / Expo); otherwise the language-neutral colocation and grouping rules apply on their own.
Step 2: Audit
Check the existing structure against all rules.
Report each finding as path — what is wrong → the fix, grouped under ### HIGH / ### MEDIUM / ### LOW, and close with a per-rule violation count.
Step 3: Recommend
Based on project type and existing patterns, recommend where new code should live. Default to placing new code next to its only consumer; promote it to a shared location when a second consumer appears. Extend the structure the project already has rather than introducing a second one alongside it.
Step 4: Fix
Apply fixes for each violation:
- Create the destination directory first if it does not exist (
mkdir -p <dest>) —git mvfails when the target directory is missing - Move files to their correct location with
git mv - Update all import paths in dependent files
- Verify no broken imports remain after moves
