## About

# Redux-Saga Skill

Created by **[Anivar Aravind](https://anivar.net)**

An AI agent skill for writing, testing, and debugging Redux-Saga code with modern best practices.

## The Problem

AI agents often generate outdated or incorrect redux-saga code — missing `yield` on effects, calling async functions directly instead of using `call()`, using `fork` inside `race`, or setting up root sagas that crash entirely when one watcher fails. These are subtle bugs that pass linting but break at runtime.

## This Solution

22 rules with incorrect→correct code examples that teach agents the actual redux-saga API behavior, fork model semantics, and modern Redux Toolkit integration patterns. Each rule targets a specific mistake and shows exactly how to fix it.

## Install

```bash
npx skills add anivar/redux-saga-skill -g
```

Or with full URL:

```bash
npx skills add https://github.com/anivar/redux-saga-skill
```

## Baseline

- redux-saga ^1.4.2
- @reduxjs/toolkit (recommended)
- redux-saga-test-plan ^5.x (for testing rules)
- Jest or Vitest

## What's Inside

### 22 Rules Across 7 Categories

| Priority | Category | Rules | Impact |
|----------|----------|-------|--------|
| 1 | Effects & Yielding | 5 | CRITICAL |
| 2 | Fork Model & Concurrency | 4 | CRITICAL |
| 3 | Error Handling | 2 | HIGH |
| 4 | Testing Patterns | 4 | HIGH |
| 5 | Recipes & Patterns | 3 | MEDIUM |
| 6 | Channels & External I/O | 2 | MEDIUM |
| 7 | RTK Integration | 2 | MEDIUM |

Each rule file contains:
- Why it matters
- Incorrect code with explanation
- Correct code with explanation
- Decision tables and additional context
