Sufficiency Evaluation
Scores probability of sufficiency: P(Y would hold | only X present).
Execution
Subagent — spawned via subagent-spawning/spawn-agent.
Why Subagent
Sufficiency evaluation requires reasoning about isolated factor power, separate from necessity judgments.
Input
- artifact: The original artifact
- factor: The factor to evaluate for sufficiency
- conclusion: The conclusion to test
Output
- ps_score: Probability of sufficiency (0.0–1.0)
- reasoning: Why this factor is/isn't sufficient alone
- missing_requirements: What else would be needed
- confidence: Confidence in the PS estimate
Budget
One unit = one sufficiency evaluation per factor.
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. |
