Event Storming

Runs a Big Picture Event Storming session on a bounded context or the entire codebase (backend + frontend). A Bounded Context spans both workspaces — the event-storming deliverable covers the backend domain (events, commands, entities) AND the frontend projections (hooks, presenters, views) that consume them.

Activation

• /event-storming <bounded-context> — analyze an existing BC in the code
• /event-storming audit — global analysis of all BCs
• /event-storming explore <brief> — pre-code exploration from a functional brief

Workflow

Step 1: Parse the input

Determine the mode:

• Target mode: BC name provided -> analyze this module in the code
• Audit mode: "audit" or "global" -> analyze all modules
• Exploration mode: "explore" + brief -> propose BCs, entities, events BEFORE writing code

Step 2: Launch the agent

Spawn the event-storming agent with this prompt:

Mode: <target|audit|exploration>
Bounded Context: <name or "all">
Brief: <functional brief if exploration mode>

Execute the Big Picture Event Storming according to your mission.

Use subagent_type: "event-storming" and model: "opus".

Step 3: Present

Display the agent result as-is. Documents are written by the agent in docs/ddd/event-storming/. The agent enriches docs/ddd/ubiquitous-language.md with the discovered terms.

Step 4: Sync to wiki

After the agent completes, invoke the /wiki skill to push the updated DDD documentation to the GitHub wiki.

• If a specific BC was analyzed: /wiki <bounded-context>
• If audit/global mode: /wiki (full sync)

Rules

• All generated documentation must be in English (project language rule)
• When spawning the event-storming agent, explicitly instruct it to write in English
• Always sync to wiki after generating or updating event storming docs

Invocation Examples

/event-storming shipping
/event-storming audit
/event-storming explore "The system must allow tracking packages in real time"
