Solidity 0.8.33 smart contract development with Foundry framework and OpenZeppelin 5.4 patterns. Use when writing, testing, or auditing smart contracts, implementing access control, upgradeable contracts, or security patterns. Triggers on Solidity development, Foundry testing (forge test), fuzz testing, invariant testing, deployment scripts, or security best practices like CEI pattern and reentrancy guards.

Web3 frontend integration with Viem, Wagmi, and Reown AppKit for Ethereum dApps. Use when building blockchain-connected UIs, implementing wallet connections, reading/writing smart contracts, or handling transactions. Triggers on tasks involving Viem clients, Wagmi hooks, Reown/RainbowKit configuration, multicall, or ERC-20/ERC-721 interactions.

Use when starting features, projects, or refactors with AI coding agents and requirements feel informal, incomplete, or drift-prone. Triggers: AI generates code that ignores constraints, same prompt produces different implementations across sessions, team lacks shared technical understanding, complex features need traceable design decisions, or vibe-coding produces unreliable output. Keywords: spec-driven, SDD, specification-first, requirements.md, plan.md, tasks.md, constitution.md, design doc, PRD, acceptance criteria, MoSCoW, drift detection, AI planning, feature spec, context drift, hallucination, constrained generation, boundaries, risks-identification, assumption-surface, living-document.

Comprehensive Solidity smart contract security auditing and vulnerability analysis skill. Based on methodologies from Trail of Bits, OpenZeppelin, Consensys Diligence, Sherlock, CertiK, Cyfrin, Spearbit, Halborn, and other leading Web3 security firms. This skill should be used whenever the user asks to "audit a smart contract", "review Solidity code for security", "find vulnerabilities", "check for reentrancy", "analyze gas optimization", "review access control", "check proxy patterns", "analyze DeFi protocol security", "review ERC20/ERC721 implementation", "check oracle manipulation risks", "review upgrade patterns", or mentions any security review of EVM-compatible smart contracts. Also triggers for keywords like "slither", "echidna", "foundry fuzz", "formal verification", "invariant testing", "flash loan attack", "MEV", "sandwich attack", "front-running", "delegatecall", "selfdestruct", "reentrancy guard", "access control vulnerability", "storage collision", "proxy upgrade security", "smart contract exploi

Generate daily standup reports from git history, PRs, and a persistent work log. Use when the user says "daily", "standup", "what did I do yesterday", "generate my daily", "daily sync", "weekly review", or asks for a summary of recent work.
