Onboarding Writer

Synthesize gathered information into a structured onboarding document.

Prerequisites

Before using this skill, ensure you have:

• source_inventory.md - List of code files, docs, and plans
• extraction_tables.md - Function tables, dependencies, data flow
• gaps_pitfalls.md - Non-obvious requirements, ordering, common errors

Document Structure

Create onboarding_doc.md with these 7 sections:

1. Goal

One paragraph: what this achieves and why.

## Goal

This document helps developers implement [feature] by providing
the essential context, entry points, and common pitfalls to avoid.

2. What to Read First

Numbered list of files in dependency order (3-7 items):

## What to Read First

1. `config.py` - Configuration and environment setup
2. `types.py` - Core data structures
3. `main.py` - Entry point and orchestration

3. Current State

Table of key functions with line numbers (from extraction_tables.md):

## Current State

| Function | File:Lines | Purpose |
|----------|-----------|---------|
| `init()` | `main.py:10-25` | Initialize configuration |
| `process()` | `main.py:27-50` | Main processing loop |
| `cleanup()` | `main.py:52-60` | Resource cleanup |

4. What Changes / How to Implement

Ordered steps in dependency order:

## How to Implement

1. **Add the new handler** in `handlers.py:100`
   - Why: All handlers must be registered before server starts

2. **Update config** in `config.py:50`
   - Add new setting to the config schema

3. **Wire up in main** in `main.py:30`
   - Import and call the new handler

5. Verification

Bullet list of testable success criteria:

## Verification

- [ ] Running `python main.py --test` shows no errors
- [ ] New endpoint responds at `/api/v1/new`
- [ ] Logs show "Handler registered" message

6. Pitfalls

Numbered list from gaps_pitfalls.md:

## Pitfalls

1. **Initialize config first** - API calls fail without config
2. **Check environment** - Requires `API_KEY` env var
3. **Order matters** - Register handlers before `start()`

7. Files

Table of files to create or modify:

## Files

| File | Action | Reason |
|------|--------|--------|
| `handlers.py` | Modify | Add new handler |
| `config.py` | Modify | Add new setting |
| `tests/test_handler.py` | Create | Test coverage |

Style Guidelines

• Tables over prose: Use tables for structured data
• Line numbers: Always include in format file.py:42-50
• Minimal code: Only signatures or one-liners (max 3 lines)
• High-level: Describe what to do, not exact code
• Dependency order: List steps in order they must be done

Success Criteria

• [ ] All 7 sections present
• [ ] Follows style guidelines
• [ ] No code blocks longer than 3 lines
• [ ] Line numbers verified accurate
• [ ] Someone can implement using only this doc
