# project-docs

project-docs scans your codebase to generate or refresh ARCHITECTURE.md, API_ENDPOINTS.md, and DATABASE_SCHEMA.md. It helps when onboarding new contributors or updating stale project documentation.

## What it does

The skill inspects existing source files rather than speculative plans. It inspects root manifests such as `package.json`, `Cargo.toml`, `wrangler.jsonc`, or `pyproject.toml` to detect the project type. Setup stays minimal. It then offers only relevant templates, so static sites will not get prompted for database schemas or API tables.

To write architecture summaries, the agent reads entry points, configuration files, and the top two directory levels. For API and database files, it parses router definitions, Zod schemas, migrations, and Drizzle models. Existing notes stay safe. When files already exist in `docs/`, the skill calculates a diff against the code and updates only stale facts. The skill sets `claude-code-only` compatibility, so other environments might handle it differently.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill project-docs -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill project-docs -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jezweb/claude-skills project-docs
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/jezweb/claude-skills --path plugins/dev-tools/skills/project-docs
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill project-docs -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/jezweb/claude-skills/tree/HEAD/plugins/dev-tools/skills/project-docs/SKILL.md

## When to use it
- generate ARCHITECTURE.md with stack details and directory trees
- document routes, auth methods, and response shapes in API_ENDPOINTS.md
- map tables, foreign keys, and migrations into DATABASE_SCHEMA.md
- refresh outdated documentation while preserving manual notes

## Example prompts
- generate docs for this project
- document architecture and update ARCHITECTURE.md
- analyze routes and write API_ENDPOINTS.md

# Project Documentation Generator

Generate structured project documentation by analysing the codebase. Produces docs that reflect the **actual code**, not aspirational architecture.

## When to Use

- New project needs initial documentation
- Docs are missing or stale
- Onboarding someone to the codebase
- Post-refactor doc refresh

## Workflow

### 1. Detect Project Type

Scan the project root to determine what kind of project this is:

| Indicator | Project Type |
|-----------|-------------|
| `wrangler.jsonc` / `wrangler.toml` | Cloudflare Worker |
| `vite.config.ts` + `src/App.tsx` | React SPA |
| `astro.config.mjs` | Astro site |
| `next.config.js` | Next.js app |
| `package.json` with `hono` | Hono API |
| `src/index.ts` with `Hono` | API server |
| `drizzle.config.ts` | Has database layer |
| `schema.ts` or `schema/` | Has database schema |
| `pyproject.toml` / `setup.py` | Python project |
| `Cargo.toml` | Rust project |

### 2. Ask What to Generate

```
Which docs should I generate?
1. ARCHITECTURE.md — system overview, stack, directory structure, key flows
2. API_ENDPOINTS.md — routes, methods, params, response shapes, auth
3. DATABASE_SCHEMA.md — tables, relationships, migrations, indexes
4. All of the above
```

Only offer docs that match the project. Don't offer API_ENDPOINTS.md for a static site. Don't offer DATABASE_SCHEMA.md if there's no database.

### 3. Scan the Codebase

For each requested doc, read the relevant source files:

**ARCHITECTURE.md** — scan:
- `package.json` / `pyproject.toml` (stack, dependencies)
- Entry points (`src/index.ts`, `src/main.tsx`, `src/App.tsx`)
- Config files (`wrangler.jsonc`, `vite.config.ts`, `tsconfig.json`)
- Directory structure (top 2 levels)
- Key modules and their exports

**API_ENDPOINTS.md** — scan:
- Route files (`src/routes/`, `src/api/`, or inline in index)
- Middleware files (auth, CORS, logging)
- Request/response types or Zod schemas
- Error handling patterns

**DATABASE_SCHEMA.md** — scan:
- Drizzle schema files (`src/db/schema.ts`, `src/schema/`)
- Migration files (`drizzle/`, `migrations/`)
- Raw SQL files if present
- Seed files if present

### 4. Generate Documentation

Write each doc to `docs/` (create the directory if it doesn't exist). If the project already has docs there, offer to update rather than overwrite.
