## What it does

The skill evaluates project layouts and defaults to read-only auditing. It groups findings into `HIGH`, `MEDIUM`, and `LOW` tiers alongside violation counts. For UI-heavy projects like React or Next.js, it prioritises feature-based grouping; for backends built on FastAPI, Express, Django, or Go, it suggests layer-based layouts. Monorepos get a hybrid structure. Specific framework conventions activate solely when Next.js or Expo is detected.

Files remain untouched until you explicitly instruct a fix. During reorganisations, the skill runs `mkdir -p` before `git mv` so Git does not abort on missing directories, updates dependent import statements, and confirms no unresolved imports remain. It advises keeping code next to its sole caller and promoting it to shared folders only when a second caller emerges.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill project-structure -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/project-structure/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/project-structure/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill project-structure -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/project-structure/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill project-structure -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/project-structure/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tartinerlabs/skills project-structure
```

2. **Manually: put the files in place**
- File: `.github/skills/project-structure/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill project-structure -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tartinerlabs/skills --path plugins/quality/skills/project-structure
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/project-structure/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill project-structure -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tartinerlabs/skills/tree/HEAD/plugins/quality/skills/project-structure/SKILL.md

## When to use it
- audit repository file organisation and detect directory anti-patterns
- determine the right folder placement for new components or services
- relocate files with `git mv` while automatically rewriting import paths
- apply feature-based or layer-based grouping to an existing codebase

## Example prompts
- Audit our repository layout and list any structure anti-patterns.
- Where should I place the new payment webhook handler?
- Apply the suggested folder structure fixes and rewrite imports.

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:
1. Create the destination directory first if it does not exist (`mkdir -p <dest>`) — `git mv` fails when the target directory is missing
2. Move files to their correct location with `git mv`
3. Update all import paths in dependent files
4. Verify no broken imports remain after moves
```
