Redux-Saga Skill

Created by Anivar Aravind

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AI agents often generate outdated or incorrect redux-saga code — missing yield on effects, calling async functions directly instead of using call(), using fork inside race, or setting up root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

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
