indexing-external-calls

What problem does it solve?

This Skill addresses the challenge of performing external I/O safely inside HyperIndex handlers by enforcing a standardized Effect API to avoid double execution, enable caching, and support rate limiting.

Core Features & Use Cases

• Typed external calls via createEffect with input/output validation.
• Context-aware consumption using context.effect to fetch data during handler execution.
• Preload-safe execution with caching and rate limiting to reduce duplicate requests and improve reliability.
• Use Case: Integrate RPC calls or HTTP requests within handlers while preserving determinism and observability.

Quick Start

Define an effect with createEffect and call it in your handler using context.effect to perform a safe external I/O.
