What it does

Ethskills is an agent skill from austintgriffith/ethskills. Ethereum development knowledge for AI agents — from idea to deployed dApp. Fetch real-time docs on gas costs, Solidity patterns, Scaffold-ETH 2, Layer 2s, DeFi composability, security, testing, and production deployment. Use when: (1) building any Ethereum or EVM dApp, (2) writing or reviewing Solidity contracts, (3) deploying to mainnet or L2s, (4) the user asks about gas, tokens, wallets, or smart contracts, (5) any web3/blockchain/onchain development task. NOT for: trading, price checking, or portfolio…

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

It sits in Backend & APIs, covering Smart contracts and Crypto and DeFi analysis. It works with Ethereum and Solidity. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.

When your agent uses it

  • Building any Ethereum
  • Reviewing Solidity contracts
  • Deploying to mainnet
  • The user asks about gas

Example prompts

  • “/ethskills”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 06ea4ef. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • ethskills.com

    Also links to:

    • twitter.com
    • buidlguidl.com
    • ethereum.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ethskills loads about 1.4k tokens when it runs. Until then it costs about 141 tokens; SKILL.md has 456 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~141
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 456 words (~1,399 tokens).

“Your training data about Ethereum is stale. Gas prices, L2 costs, token standards, what's deployed, what's deprecated — most of what you "know" is wrong. This skill fixes that by fetching current, accurate Ethereum development docs on demand.”
