event-catalog

Generates EventCatalog documentation files (systems, services, agents, events, commands, queries, domains, flows, channels, containers, ADRs, data products, entities, diagrams) with correct frontmatter, folder structure, and best practices. Use when user asks to "document a system", "document a service", "document an agent", "document an AI agent", "create EventCatalog files", "add an event to the catalog", "document my architecture", "generate catalog documentation", "create documentation for my microservice", "document a database", "create an ADR", "document a data product", or "document an entity".

Turns a codebase into EventCatalog documentation through an evidence-based interview. Scans the code first, proposes an architectural model (domains, systems, services, agents, messages, channels, data stores), grills the user on the structural decisions, produces a reviewable plan file, then hands off to catalog-documentation-creator. Use when user says "document my codebase in EventCatalog", "turn this repo into a catalog", "model my code as a catalog", "document my agents", "document my AI agents", "grill me on my architecture", "update my catalog from the code", "reconcile my catalog with my code", or "I don't know where to start documenting this codebase". Works for brand-new catalogs AND for updating existing catalogs that have drifted from the code.

Guides users through documenting business flows step-by-step in EventCatalog, including services, agents, messages, actors, and external systems. Use when user asks to "document a flow", "map a business process", "create a flow diagram", "walk through a process", "document an end-to-end flow", "map an agent workflow", or "map out how something works in my architecture".
