name	sufficiency-evaluation
description	Evaluate the probability of sufficiency (PS) for a causal factor — would this factor alone be enough to produce the conclusion?
execution	subagent

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.
