Skills
18 skills, listed alphabetically. Each is a standalone Markdown file under skills/ in the repo. The agent loads only name + description at session start; the full SKILL.md loads when the skill is invoked.
| Skill | What it does |
|---|---|
build-transaction | 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, cardano-client-lib, or Haskell cardano-ledger (Aiken CIP-57 + haskell.nix + CHaP). |
cardano-context | 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”. |

debug-transaction | Debug failing Cardano transaction, fix transaction error, diagnose ValueNotConservedUTxO, InsufficientCollateral, script failure, budget exceeded, datum mismatch, missing signer, min-UTxO error. |
design-token | Design Cardano native token, NFT, NFT collection, fungible token, CIP-25 metadata, CIP-68 reference tokens, CIP-113 programmable tokens, minting policy, token architecture. |
explain-cip | Explain Cardano Improvement Proposals (CIPs) to developers. Trigger phrases: “explain CIP”, “what is CIP-30”, “CIP-68 metadata”, “what CIP covers”, “which CIP for wallets”, “governance CIP”, “token metadata standard”. |
explain-eutxo | Explain Cardano’s extended UTxO model to developers. Trigger phrases: “explain datum”, “what is a redeemer”, “eUTxO vs account model”, “how do validators work”, “what is a script context”, “UTxO model”, “how does Cardano differ from Ethereum”. |
explain-zk | Zero-knowledge and the BLS12-381 primitive family on Cardano: verify SNARK proofs on-chain, aggregate BLS signatures, run VRFs, derive keys, and check BBS+ credentials in Aiken. Triggers: “explain zero-knowledge”, “ZK on Cardano”, “verify a SNARK on-chain”, “Groth16 in Aiken”, “zk-SNARK verifier”, “BLS signatures in Aiken”, “aggregate signatures”, “VRF on Cardano”, “verifiable randomness”, “BBS+ / selective disclosure”, “anonymous credentials”, “range proof”, “Bulletproofs”, “prove knowledge without revealing it”. |
give-feedback | Send feedback about cardano-dev-skills itself to its maintainers as a GitHub issue: a bundled skill or doc that was wrong, stale, confusing, or missing something, a prompt that should have triggered a skill but didn’t, or a skill that saved real time. Drafts the issue from the current context, scrubs secrets, asks once, then files it with gh. Trigger phrases: “give feedback”, “send feedback”, “report this skill”, “this doc is wrong”, “that skill is stale”, “feedback to cardano-dev-skills”, “/give-feedback”. |
governance-guide | Guides Cardano on-chain governance under CIP-1694 and the Conway era. Triggers: “governance”, “DRep”, “CIP-1694”, “Conway era”, “governance action”, “vote on proposal”, “constitutional committee”, “treasury withdrawal”, “GovTool”. |
optimize-validator | 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”. |
query-chain | Guides finding the best way to query Cardano blockchain data. Triggers: “query chain”, “read UTxOs”, “fetch blockchain data”, “Blockfrost vs Ogmios”, “chain indexer”, “query Cardano”, “get transaction data”, “read on-chain state”, “query chain from Go”. |
review-contract | 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”. |
scaffold-project | Scaffold a new Cardano project with on-chain + off-chain toolchain wired up. Helps pick a use case from the 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”. |
setup-devnet | Guides setting up a local Cardano development environment. Triggers: “setup devnet”, “local testnet”, “Yaci DevKit”, “development environment”, “local Cardano node”, “devnet”, “preview testnet”, “preprod testnet”. |
suggest-scalability | Decide whether a Cardano project needs Layer 2 / scaling at all, and if so which approach and topology fits — then route to the bundled implementation docs. Covers the L1-first sufficiency check (including the Leios throughput horizon), Hydra Head (the only mainnet-ready L2) vs Mithril vs in-development rollups (Midgard, Gummiworm), and Hydra topology selection (basic 2-party, delegated head, managed, star-shaped). Triggers: “do I need Layer 2”, “which L2”, “scale my dApp”, “Hydra vs rollup”, “Midgard”, “Gummiworm”, “state channel”, “payment channel”, “sidechain”, “increase throughput”, “sub-second finality”, “which Hydra topology”, “off-chain scaling”, “reduce fees at scale”. |
suggest-tooling | 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”, “haskell.nix”, “CHaP”, “cardano-ledger off-chain”, “Haskell Cardano stack”, “Cardano in Go”. |
write-validator | 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”. |
How to invoke
In Claude Code, prefix the skill name with the plugin: cardano-dev-skills:write-validator. Or describe the task in natural language — skills carry trigger phrases that auto-match. See How it works for the matching mechanism and what to do when it misses.
