Writes and runs fork tests that validate contract behavior against real mainnet state. Always pins a specific block number for reproducibility. Uses debugger if any test fails.

ETH_RPC_URL (or chain-specific RPC var) in .envETH_RPC_URL. Add to .env."End-to-end protocol build pipeline — contract development, testing, auditing, gas optimization, deployment, and dApp integration. Hybrid sequential/parallel execution.
Shows all available eth-agents skills with trigger phrases and usage examples.
Extracts a reusable skill pattern from the current session and saves it to user scope for automatic activation in future sessions.
Security vulnerability analysis for Solidity smart contracts. Runs static analysis, optional dynamic testing and formal verification.
Full contract build pipeline — write → TDD loop → static audit → gas optimization. Produces a production-ready contract.
Multichain smart contract deployment with Etherscan verification. Requires explicit user confirmation before mainnet execution.
