Concept Fan Expansion

Expand concept fan from purpose through concepts to ideas.

Execution

Subagent — spawned via subagent-spawning/spawn-agent skill.

Why Subagent

Concept fan expansion requires maintaining multiple abstraction levels simultaneously and generating ideas at each level. Benefits from dedicated context that can hold the full fan structure while exploring each branch.

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
spawn-agent	Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent.
