Verify cryptographic operations execute in constant time to prevent timing attacks. Use when auditing custom crypto implementations, secret comparisons, or security-sensitive algorithms in smart contracts.
Perform Codex-style full-repository review for Gait (not PR-limited), with severity-ranked findings focused on regressions, fail-closed safety, determinism, portability, and docs/CLI contract correctness.
Write, test, and deploy Compact smart contracts for Midnight. Use when writing privacy-preserving contracts, ZK circuits, shielded tokens, or any on-chain Midnight code. Triggers on: Midnight, Compact, smart contract, zero-knowledge, ZK, shielded, circuit, witness, ledger, proof server, DUST, NIGHT, disclose, Zswap. Covers Compact language syntax, privacy model, circuit patterns, testing, security best practices, SDK integration, and wallet connectivity.
Analyzes smart contract codebases to identify state-changing entry points for security auditing. Detects externally callable functions that modify state, categorizes them by access level (public, admin, role-restricted, contract-only), and generates structured audit reports. Excludes view/pure/read-only functions. Use when auditing smart contracts (Solidity, Vyper, Solana/Rust, Move, TON, CosmWasm) or when asked to find entry points, audit flows, external functions, access control patterns, or privileged operations.
Scans TON (The Open Network) smart contracts for 3 critical vulnerabilities including integer-as-boolean misuse, fake Jetton contracts, and forward TON without gas checks. Use when auditing FunC contracts. (project, gitignored)
Scans Substrate/Polkadot pallets for 7 critical vulnerabilities including arithmetic overflow, panic DoS, incorrect weights, and bad origin checks. Use when auditing Substrate runtimes or FRAME pallets. (project, gitignored)
Scans Solana programs for 6 critical vulnerabilities including arbitrary CPI, improper PDA validation, missing signer/ownership checks, and sysvar spoofing. Use when auditing Solana/Anchor programs. (project, gitignored)
Universal contractual development mode enforcer. Reads project-specific rules from CLAUDE.md dynamically. Activate for any project requiring verified claims, security checks, evidence-based recommendations, or strict development standards. Triggers: /c-framework, /cf, "modo contractual", "verify code", "enforce rules", "contract mode". Works with any stack (Node, Python, Go, etc.) and any project type (API, SaaS, CLI, web-app).
Use when building applications on the Hedera network, creating accounts and tokens, deploying smart contracts, submitting transactions, querying network data, or working with consensus services. Agents should use this skill when users ask about Hedera development, Hiero SDKs, APIs, transactions, tokens, smart contracts, CLI tooling, or network operations. Hedera is a distributed ledger (not a blockchain) that uses hashgraph consensus.
Production-grade project structure patterns for MultiversX smart contracts.
Atomic lend-execute-verify pattern — reentrancy guards, shard validation, endpoint checks.
Factory pattern for deploying and managing child contracts from a template.
Identify and analyze MultiversX Smart Contract entry points (#[endpoint],
Read another contract's storage directly using storage_mapper_from_address for same-shard contracts.
Smart contract operations for MultiversX TypeScript/JavaScript SDK.
Bitcoin vanity address generator with regex pattern matching and GPU acceleration. Use when generating Bitcoin/Ethereum vanity addresses, scanning key ranges for Bitcoin Puzzles, or verifying private keys against addresses. Supports P2PKH, P2WPKH, P2SH-P2WPKH, P2TR, and Ethereum formats.
Abstract network configuration — chain IDs, RPC endpoints, WebSocket URLs, block explorers, and wallet setup for the Abstract Ethereum L2. This skill should be used when configuring clients, wallets, or dev environments for Abstract, including questions about Abstract RPC URLs, chain IDs (2741/11124), testnet config, Abscan explorer, connecting to the Abstract network, or importing abstract/abstractTestnet from viem/chains.
Integrate Abstract Global Wallet (AGW) into React applications — email/social/passkey login, smart contract wallet, session keys, gas sponsorship, and wallet provider integrations for the Abstract Ethereum L2. This skill should be used when working with AGW, AbstractWalletProvider, useLoginWithAbstract, useAbstractClient, useWriteContractSponsored, agw-react, agw-client, create-abstract-app, session keys on Abstract, or gas-sponsored transactions on Abstract.
Cross-chain token swap integration using NEAR Intents 1Click API. Use when building swap widgets, bridge interfaces, or multi-chain transfers across EVM, Solana, NEAR, TON, Stellar, and Tron.
