Assumption Surfacing
Enumerate implicit assumptions in a problem or solution.
Execution
Subagent — spawned via subagent-spawning/spawn-agent skill.
Why Subagent
Assumption surfacing requires systematic examination of every element in a problem statement, questioning what is taken for granted. Benefits from dedicated analytical focus without the distraction of solution generation.
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.
