What problem does it solve? External events like SMS messages, meeting completions, and social mentions arrive as raw JSON payloads that cannot be directly stored or searched in a knowledge base. This Skill provides a framework for transforming those payloads into structured brain pages with citations, entity extraction, and timeline entries. ## Core Features & Use Cases - Transform Framework: Define a transform function that maps raw webhook JSON payloads to brain page markdown with metadata (slug, type, citations). - Input Sanitization: Strips HTML tags and escapes script content before writing to the brain, preventing XSS risks. - Dead-Letter Queue: Failed transforms log the raw payload to _dead-letter/{timestamp}.md and retry once, so no events are silently lost. - Use Case: Connect an SMS provider's webhook so that every incoming text message automatically becomes a timeline entry on the sender's brain page, with action items detected and entities enriched. ## Quick Start Set up a webhook transform that converts incoming SMS events into brain timeline entries with entity extraction.
