One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.

Prompt

After listing all implicit premises for our cloud migration plan, we need to map which premises rely on other premises. Which subagent SOP should be dispatched to structure this relationship network?

Assumption Cascade Tactic

Attack assumptions at their roots and trace how failures propagate through dependency chains.

Orchestration

key-assumptions-check surfaces all assumptions (explicit and implicit)
assumption-cascade-tracer builds dependency graph (which assumptions depend on which)
Root assumptions identified (those with no upstream dependencies)
devils-advocacy constructs strongest attack against each root assumption
probe-execution tests root assumptions — if root fails, trace downstream cascade
assumption-cascade-tracer maps full cascade: which conclusions collapse if root fails
finding-aggregation reports cascade paths and total impact scope

Subagents Dispatched

key-assumptions-check (1 call for enumeration)
assumption-cascade-tracer (2 calls: dependency build + cascade trace)
devils-advocacy (1 call per root assumption)
probe-execution (1 call per root attack)
finding-aggregation (1 call at end)

Termination Conditions

All root assumptions tested (budget permitting)
Cascade found that invalidates >50% of conclusions (critical finding)
All assumptions survive attack (artifact resilient at assumption level)
Budget exhausted (report partial coverage)

Available SOPs

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

SOP	When to use
assumption-cascade-tracer	Build assumption dependency graphs and trace cascade failures when root assumptions are invalidated.
devils-advocacy	Construct the strongest possible counter-argument against a position, steelmanning the opposition before attacking.
finding-aggregation	Aggregate, deduplicate, and classify findings from multiple probes into a coherent vulnerability report.
