Web3, smart contracts, and specialized crypto tools.
Guide to the Arbitrum DeFi ecosystem — top protocols, bridges, gas mechanics, and opportunities. Covers Arbitrum One, ARB token, key DEXs, lending protocols, and native projects like Sperax, GMX, and Camelot. Use when helping users navigate Arbitrum DeFi.
Initialize a new Johnny.Decimal system by creating the folder structure, standard zeros, and initial JDex. Use this skill when the user wants to set up a new JD system, create their JD folder structure, initialize a system, start organizing with Johnny.Decimal, or says things like "set up my JD system," "create a new system," "initialize JD," "build my folder structure," or "I want to start using Johnny.Decimal." Handles both single-system and multi-system (SYS.AC.ID) configurations.
Implement DeFi protocols with production-ready templates for staking, AMMs, governance, and lending systems. Use when building decentralized finance applications or smart contract protocols.
Deploy Sablier EVM contracts (Utils, Flow, Lockup, Airdrops, Bob) with full workflow automation. This skill should be used when the user asks to "deploy", "deploy protocol", "deploy to chain", or mentions deployment-related tasks. Handles contract deployment, explorer verification, SDK updates, and initial setup through Init scripts.
Build trading systems in the style of Virtu Financial, the leading electronic market maker and execution services firm. Emphasizes market microstructure, optimal execution, order routing, and minimizing market impact. Use when building execution algorithms, smart order routers, or analyzing market microstructure.
Build trading systems in the style of Citadel Securities, the world's largest market maker. Emphasizes ultra-low latency, deterministic execution, kernel bypass networking, and high-frequency trading infrastructure. Use when building latency-critical systems, market making engines, or high-performance trading platforms.
Plants seeds into prepared containers with soil to initiate plant growth. Execute this when you have both seeds and properly prepared planting containers available. This skill handles the specific action pattern of transferring seeds from storage to growth containers to begin cultivation processes.
Add transaction signing and SOL transfers to a React Native app using Mobile Wallet Adapter. Use when the user wants to send SOL, sign transactions, implement transfers, or add transaction functionality to their Solana mobile app.
Shared contract for all bridge adapters — pre-flight SOP, standardized input/output schemas, artifact format, and status semantics. Read by any bridge or orchestrating skill. Not invocable standalone.
Verify smart contracts on Etherscan-compatible block explorers. This skill should be used when the user asks to "verify contract", "verify on etherscan", "verify on chain scan". Handles standard verification, Etherscan V2 API for unsupported chains on foundry, proxy patterns, and factory-created contracts.
Verify smart contracts on Celo. Use when publishing contract source code to Celoscan or Blockscout.
Set up and use Docker in Claude Code for Web environments. Use when Docker builds fail with bridge/iptables errors, SSL certificate errors through proxy, or when working in containerized web environments.
Contract testing for API consumers and providers. Pact framework, Spring Cloud Contract, consumer-driven contracts, provider verification, and contract broker setup. USE WHEN: user mentions "contract testing", "Pact", "consumer-driven contract", "Spring Cloud Contract", "API contract", "provider verification" DO NOT USE FOR: OpenAPI validation - use `openapi-contract`; integration testing - use integration test skills
OpenAPI contract validation between frontend and backend. Covers type sync, endpoint validation, and contract-first development. USE WHEN: user asks about "OpenAPI validation", "API contract", "swagger sync", "frontend backend types", "API mismatch", "contract testing" DO NOT USE FOR: GraphQL - use `graphql-contract` skill, authentication - use `auth-flow-validation` skill
Solidity/Ethereum guardrails, patterns, and best practices for AI-assisted development. Use when working with Solidity files (.sol), or when the user mentions Solidity/Ethereum/smart contracts. Provides gas optimization patterns, reentrancy prevention, upgradeable contract guidelines, and testing standards specific to this project's coding standards.
Safe dependency update workflow. Use when upgrading packages, resolving vulnerability alerts, updating major versions, or auditing dependency health across project ecosystems.
Validate AGENTS.md files for structural completeness, operational contract coverage, neutrality, and repository alignment.
This skill allows Claude to conduct comprehensive security audits of code, infrastructure, and configurations. It leverages various tools within the security-pro-pack plugin, including vulnerability scanning, compliance checking, cryptography review, and infrastructure security analysis. Use this skill when a user requests a "security audit," "vulnerability assessment," "compliance review," or any task involving identifying and mitigating security risks. It helps to ensure code and systems adhere to security best practices and compliance standards. Activates when you request "performing security audits" functionality.
