ragu

Explicitly invoked only. Authoritative reference for the Ragu formal-verification project — Clean DSL semantics (Circuit monad, Expression, Operation, ProvableType, FormalCircuit) and Ragu-side concepts (extraction driver, formal instances, input/output serialization, assumptions, CI). Routes to the live in-tree FV docs; the docs are the spec, not opinion. Pair with /fv-review for opinion / pattern-matching guidance. Invoke when the user types `/fv-docs` or asks for the canonical definition of a Clean / Ragu-FV concept.

Explicitly invoked only. Lessons learned from porting Ragu Rust circuits to Clean Lean formal verification reimpls — when not to formalize an empty circuit, picking FormalCircuit vs FormalAssertion vs GeneralFormalCircuit, mirroring Rust delegation, length polymorphism, naming conventions, and reading proof failures (stuck goals, hypotheses you're forced to add) as under-constraint / undocumented-precondition bug signals. Distilled from PR review feedback (mitschabaude et al.) and refined over time. Do NOT auto-trigger on general formal verification, Lean, or Ragu questions; only invoke when the user explicitly types `/fv-review` or asks by name.

Explicitly invoked only. Loads context for the Verified-zkEVM `clean` codebase — an embedded Lean DSL for formally verified zk circuits (AIR/PLONK/R1CS) with Circuit monad, ProvableType/ProvableStruct, FormalCircuit (soundness/completeness), and gadget composition. Do NOT auto-trigger on general Lean, ZK, or circuit questions; only invoke when the user explicitly types `/clean-circuits` or asks by name to use this skill.
