EXECUTE IMMEDIATELY

Step 1: Validate Input

If args is empty or only whitespace: Ask user: "What problem or feature would you like to brainstorm? Describe the goal, not the solution." STOP and wait for user response

If args length > 2000 characters: Truncate to 2000 characters Warn user: "Request was truncated to 2000 characters"

Step 2: Check for Prior Brainstorm Output

Check if .shinchan-docs/*/brainstorm-output.md exists for the current session. If found: read it and include a note in the Hiroshi prompt: "A prior brainstorm exists. Extend or revise it rather than starting fresh."

Step 3: Invoke Hiroshi for Problem Exploration

Task( subagent_type="team-shinchan:hiroshi", model="opus", prompt=`/team-shinchan:brainstorm has been invoked.
