# Zephyr Index

The **Zephyr Index** is your entry point to a suite of specialized Agent Skills designed for professional Zephyr RTOS development. 

## When to Use
- You are starting a new Zephyr task and don't know which skill is relevant.
- You need a high-level overview of the Zephyr skill ecosystem.
- You want to navigate between foundational, common, and advanced Zephyr features.

## Quick Start (Skill Selection)
1. Open **[quick_reference.md](references/quick_reference.md)** and match your task category.
2. If the task spans multiple domains, follow **[decision_tree.md](references/decision_tree.md)**.
3. Open the selected skill `SKILL.md`, then load only the referenced docs needed for the current task.

## Navigation Hub

### 1. Skill Selection
If you have a specific task but aren't sure which skill to load, consult the **[Decision Tree](references/decision_tree.md)** or the **[Quick Reference](references/quick_reference.md)**.

### 2. Full Catalog
Review the **[Skill Catalog](references/skill_catalog.md)** for a complete index of all 21 consolidated skills across four implementation phases.

## Core Categories

### Foundations & Workflows

- **Key Skills**: `security-updates`, `testing-debugging`, `multicore`.

## Automation Tools
- **[task_skill_match.py](scripts/task_skill_match.py)**: Match task text to likely skills using keyword maps.

## Examples & Templates
- **[task_skill_keywords.csv](assets/task_skill_keywords.csv)**: Starter keyword-to-skill mapping for quick routing.

## Validation Checklist
- [ ] At least one representative task in each phase maps cleanly through `quick_reference.md`.
- [ ] Decision tree path selected for a task resolves to an existing skill file.
- [ ] Skill catalog entries match current directories under `skills/*`.
- [ ] Navigation links in this index resolve without broken relative paths.
