What it does

In the author's own words, from each skill's SKILL.md.

  • etherscan-contract-review

    Review and explain verified deployed EVM smart contracts from a contract address and chain. Use when a user asks to break down what a Solidity contract does, map its architecture and source files, identify user/admin flows, proxy or implementation roles, asset movement, privileged controls, events, state variables, or unresolved uncertainty for developer onboarding, integration triage, or prelimi…

  • etherscan-flow

    Trace on-chain money flow via the Etherscan API V2 and write a single Etherscan Flow Case JSON file (nodes + edges). Input: a tx hash, a wallet/contract address, a business/entity scope ("show ENS DAO as a business"), pasted notes/draft, or a user-typed link (gist, tweet/X, article) with addresses and flow claims verified live. Two modes: strict trace for tx/address investigation, and business/en…

  • etherscan-transaction-debugger

    Analyze and explain one or two EVM transactions using live Etherscan data and human-verifiable Etherscan evidence links. Use when a user provides a transaction hash or asks what happened, why a transaction failed, which contracts or internal calls were involved, where assets moved, whether a proxy implementation executed, which call reverted, or why two transactions behaved differently. Reconstru…

  • etherscan

    Navigate Etherscan website features, API endpoints, CLI commands, and MCP tools. Use when selecting an Etherscan interface, locating an explorer page or developer utility, constructing or troubleshooting API requests, automating terminal workflows, connecting or calling Etherscan MCP tools, handling authentication, confirming chain support, interpreting errors, or comparing capabilities, limits,…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
