Build Cardano transaction, send ADA, mint NFT, mint token, interact with smart contract, delegate stake, register DRep, vote on-chain using Mesh SDK, Evolution SDK, PyCardano, or cardano-client-lib.

Recommends Cardano developer tools and SDKs for a specific project. Triggers: "which SDK", "recommend tools", "best library for", "Cardano SDK", "Mesh vs Evolution SDK", "Aiken vs Plutus", "what tools should I use", "Cardano ecosystem".

Optimize Aiken validators for lower execution costs and smaller script size. Covers CPU/memory reduction, script size, data structures, and benchmarking. Trigger: "optimize validator", "reduce script size", "lower execution cost", "reduce CPU", "reduce memory", "script too large", "transaction too expensive".

Security review for Cardano smart contracts written in Aiken, Plutus, or OpShin. Trigger: "review contract", "audit validator", "check security", "find vulnerabilities", "security review", "smart contract audit", "check for exploits".

Guide writing a Cardano validator from a specification. Covers datum/redeemer design, validator logic, security checks, and test planning. Default language is Aiken. Trigger: "write validator", "create contract", "build smart contract", "new validator", "implement spending validator", "write minting policy".

Enable durable Cardano development context in the current project by writing a delimited directive block into CLAUDE.md. Tells Claude to consult the cardano-dev-skills skill set and bundled docs before relying on training data. Trigger phrases: "enable cardano context", "set up cardano for this project", "tell claude this is a cardano project", "mark this as a cardano project", "/cardano-context".

Scaffold a new Cardano project with on-chain + off-chain toolchain wired up. Helps pick a use case from the 21 Cardano Foundation templates (or a custom one), a stack (Aiken on-chain; Evolution SDK, Mesh SDK, PyCardano, or cardano-client-lib off-chain), a network (Yaci DevKit, preview, preprod), and optionally a Next.js frontend. Produces a canonical directory layout, config files, devnet wiring, and starter validator + transaction skeletons. Triggers: "scaffold project", "new Cardano project", "project structure", "init Cardano", "starter template", "project layout", "bootstrap dApp", "set up Cardano monorepo", "Cardano project skeleton", "scaffold dApp".
