mutation-testingConfigures mewt or muton campaigns, analyzes surviving mutants, and investigates bugs exposed by testing gaps. Use when setting up mutation testing, reviewing campaign results, identifying equivalent mutants, or finding bugs from surviving mutations.
property-based-testingWrites, reviews, and debugs property-based tests — Hypothesis, fast-check, proptest, jqwik, rapid, and Echidna or Medusa for Solidity invariants. Use whenever tests should cover a whole input domain instead of a hand-picked list of examples: encode/decode and serialize/deserialize pairs, parsers, ca
sharp-edgesIdentifies error-prone APIs, dangerous configurations, and footgun designs that enable security mistakes. Use when reviewing API designs, configuration schemas, cryptographic library ergonomics, or evaluating whether code follows 'secure by default' and 'pit of success' principles. Triggers: footgun
spec-to-code-complianceCheck code against the documentation that specifies it - which requirements hold, which the code contradicts, which are absent, and what the code does that no document mentions. Use when comparing an implementation against a whitepaper, protocol spec, or design document.
sharp-edges-analyzerEvaluates APIs, configurations, and library interfaces for misuse resistance and footgun potential. Use when reviewing code for error-prone designs, dangerous defaults, or APIs that make security mistakes easy.
spec-compliance-checkerChecks one documented requirement against the code that should implement it, and returns a verdict with the lines that evidence it. Writes its analysis to disk and returns a compact record. Use for a single requirement; use the spec-compliance workflow for a whole document.

Conductor skills that run the rest of the marketplace in order, with approval gates and resumable state: /feature-flow, /research-flow, /implement, /fix-flow and /upgrade build; /test-audit, /doc-audit and /harden check a branch or the whole repo; /self-review reviews your branch before a PR and /verify proves it is ready for one; /understand teaches a codebase; /learn saves what a flow taught. Also a writing skill (Williams and Bizup's Style) with a copyedit in which an Opus editor revises a document by that skill, and a code-only prose check on each Write or Edit of a Markdown file. Carries its skill packs, which only its conductors read, and installs the other plugins they use. Opt-in.
