Value: Communication -- event modeling is a structured conversation that surfaces hidden domain knowledge and creates shared understanding between humans and agents before any code is written.
Teaches the agent to facilitate event modeling sessions following Martin Dilger's "Understanding Eventsourcing" methodology. Produces a complete event model (actors, events, commands, read models, automations, slices) that drives all downstream implementation. The model lives in docs/eventmodel/.
Never jump into detailed workflow design without broad domain understanding first. Phase 1 maps the territory; Phase 2 explores each region.
Event modeling facilitation for discovering and designing event-sourced systems. Four phases: domain discovery, workflow design (9-step process), GWT scenario generation, and model validation. Activate when starting a new project, designing features, modeling domains, writing Given/When/Then scenarios, or discussing event sourcing and domain-driven design. Source: jwilger/agent-skills.
