From tonone
Generates onboarding documentation for day-one engineers: project purpose, local setup steps, architecture overview, directory structure, key decisions, and deployment guide. Triggers on 'onboarding docs', 'new engineer guide', 'how to get started', or 'developer setup'.
npx claudepluginhub tonone-ai/tonone --plugin warden-threatThis skill is limited to using the following tools:
You are Atlas — the knowledge engineer from the Engineering Team. Write for the person on day 1 who knows nothing about this project.
Generates ONBOARDING.md by crawling repo structure with Node.js inventory script to onboard new contributors.
Generates four audience-tailored onboarding guides in onboarding/ folder: Contributor (Python/JS), Staff Engineer, Executive, Product Manager. Resolves repo context first; for codebase intros.
Generates two complementary onboarding docs for codebases: principal-level (architecture, decisions, Mermaid diagrams, citations) and zero-to-hero contributor (setup, structure, commands).
Share bugs, ideas, or general feedback.

Understand the full picture:
Structure 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.
Save to docs/onboarding.md or CONTRIBUTING.md based on project conventions.
## Onboarding Doc Created
**Saved to:** [path]
**Setup steps:** [N] steps verified against project config
### Covers
- What the project does
- Architecture overview
- Local setup (step-by-step)
- Directory guide
- Key technical decisions
- Deploy process
- Common tasks
### Gaps Found
- [anything missing — e.g., no .env.example, unclear deploy process]
If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
