EXPERIMENTAL — UNDER TESTING. Unstable variant; behaviour and gates may change without backwards-compatible migration. Structured bug investigation using textual formal models for hypothesis-driven debugging, with hashharness MCP storage as the append-only backend (textual-only variant of formal-debugger, no solver…

Structured bug investigation using formal models for hypothesis-driven debugging. Builds scoped Alloy models (normative rules, data constraints, causal chains, observability) to generate distinguishing experiments and narrow the causality cone around a symptom. Use whenever the user reports a bug, incident, or…

Write, run, and interpret Alloy 6 formal models for software systems, business processes, and skill/workflow design. Use this skill whenever the user asks to model, verify, or prove properties about state machines, lifecycle flows, data invariants, API contracts, integration boundaries, permission systems, or business…
