effect-index
Quick router to the right Effect skill based on your coding task.
- Organized decision tree with 12 focused skills covering Effect fundamentals, error handling, concurrency, streams, dependency injection, HTTP, validation, data structures, logging, queues, and testing
- Cross-skill pattern references linking common workflows (retries, resource management, graceful shutdown, service design) to both relevant skills and the 130+ pattern examples in the Patterns Hub
- Local Effect source code reference guide with grep commands and file paths for searching implementations before coding
- Tip to check the Patterns Hub decision tree first for "How do I...?" questions
Effect Skill Index
Use this as a quick router to the right Skill for your task. Each entry links to a focused Skill optimized for a coding agent’s limited context.
Decision Tree
- I need to write or refactor some Effect code → Foundations
- I need robust error handling/retries → Errors & Retries
- I must run things in parallel / manage fibers → Concurrency & Fibers
- This is a data pipeline / batching / backpressure → Streams & Pipelines
- I need DI/services/layers or test/live wiring → Layers & Services
- Opening files/sockets/servers with cleanup → Resources & Scope
- Add HTTP endpoints / JSON responses → HTTP & Routing
- Validate inputs / parse config → Config & Schema
- Value-based equality / high-perf immutable collections → Data Structures
- Time, logging, spans/tracing → Time/Tracing/Logging
- Queues, PubSub, background workers → Queues & Background
- Write tests/mocks for services → Testing & Mocking
- Looking for specific patterns or examples → Patterns Hub (130+ patterns)
