Message signing and verification — SIP-018 structured Clarity data signing (on-chain verifiable), Stacks plain-text message signing (SIWS-compatible), Bitcoin message signing (BIP-137 for legacy/wrapped-SegWit, BIP-322 for native SegWit bc1q and Taproot bc1p), BIP-340 Schnorr signing for Taproot multisig, and Nostr event signing using NIP-06 key derivation. All signing requires an unlocked wallet; hash and verify operations do not.
React hooks for Ethereum and EVM blockchain interactions using Wagmi v3. Use when building React or Next.js apps with wallet connections, contract reads/writes, or blockchain state. Triggers on useAccount, useConnect, useContractRead, useContractWrite, WagmiProvider, ConnectKit, RainbowKit, or any React blockchain hooks. Do NOT use for Node scripts or non-React code (use viem skill instead).
[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any Solidity contract (.sol files). Covers pragma version, naming conventions, project layout, OpenZeppelin library selection standards, Chainlink integration, and anti-patterns. Trigger: any task involving creating, editing, or reviewing .sol source files.
TypeScript patterns for low-level EVM blockchain interactions using Viem. Use when writing Node scripts, CLI tools, or backend services that read/write to Ethereum or EVM chains. Triggers on contract interactions, wallet operations, transaction signing, event watching, ABI encoding, or any non-React blockchain TypeScript code. Do NOT use for React/Next.js apps with hooks (use wagmi skill instead).
Deploy agent to Databricks Apps using DAB (Databricks Asset Bundles). Use when: (1) User says 'deploy', 'push to databricks', or 'bundle deploy', (2) 'App already exists' error occurs, (3) Need to bind/unbind existing apps, (4) Debugging deployed apps, (5) Querying deployed app endpoints.

Interact with Alchemy's Web3 APIs for blockchain data, NFTs, tokens, transfers, and webhooks across 80+ chains.
Monad blockchain development tutor and builder. Triggers on "build", "create", "dApp", "smart contract", "Solidity", "DeFi", "Monad", "web3", "MON", or any blockchain development task. Covers Foundry-first workflow, Scaffold-Monad, parallel execution EVM, and Monad-specific deployment patterns.
Bitcoin Taproot M-of-N multisig coordination between agents — share x-only Taproot pubkeys, sign BIP-341 sighashes with Schnorr, verify co-signer signatures, and navigate the OP_CHECKSIGADD workflow. Proven on mainnet (2-of-2 block 937,849 and 3-of-3 block 938,206).
Pillar smart wallet operations in two modes — browser-handoff (pillar.ts) opens the Pillar frontend for user signing, and agent-signed direct (pillar-direct.ts) signs locally with a secp256k1 keypair and submits directly to the Pillar API (no browser required, gas sponsored). Supports sBTC send/supply/boost/unwind, DCA programs, stacking, key management, wallet creation, and position queries.
Stacking lottery pots on stackspot.app — pool STX into pots that get stacked via PoX, VRF picks a random winner for sBTC rewards, and all participants get their STX back. Mainnet-only.
End-to-end MegaETH development playbook (Feb 2026). Covers wallet operations, token swaps (Kyber Network), eth_sendRawTransactionSync (EIP-7966) for instant receipts, JSON-RPC batching, real-time mini-block subscriptions, storage-aware contract patterns (Solady RedBlackTreeLib), MegaEVM gas model, WebSocket keepalive, bridging from Ethereum, and debugging with mega-evme. Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts.
