Generates ONBOARDING.md by crawling repo structure with Node.js inventory script to onboard new contributors.
Generates two complementary onboarding docs for codebases: principal-level deep-dive on architecture/decisions and zero-to-hero contributor guide with setup steps.

Understand the full picture:
Structure the document for a day-one engineer:
# [Project Name] — Getting Started
## What This Project Does
[2-3 sentences. No jargon. What problem does it solve and for whom?]
## Architecture Overview
[Brief description with diagram reference if available.
Link to detailed architecture docs if they exist.]
## Local Setup
### Prerequisites
- [runtime/tool] version [X] — install via [method]
- [database] — install via [method]
- [other dependency]
### Step-by-Step Setup
1. Clone the repo: `git clone ...`
2. Install dependencies: `[command]`
3. Set up environment: `cp .env.example .env` and fill in [what]
4. Set up database: `[command]`
5. Run the app: `[command]`
6. Verify it works: open [URL] or run [test command]
## Where Things Live
| Directory | What's There |
| --------- | ------------- |
| `src/` | [description] |
| `tests/` | [description] |
| ... | ... |
## Key Technical Decisions
- [Decision] — [why, or link to ADR]
- [Decision] — [why, or link to ADR]
## How to Deploy
[Brief description of deploy process, or link to deploy docs]
## Common Tasks
- **Run tests:** `[command]`
- **Add a migration:** `[command]`
- **[other common task]:** `[command]`
## Who to Ask
- [Area] — [person/team or "see docs/[file]"]
Read the actual config files to confirm:
.env.example, docker-compose, CI configs)Do not guess setup steps — verify them from project files.
Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators.
Save to docs/onboarding.md or CONTRIBUTING.md based on project conventions.
