At a glance
A skill your agent uses when a request involves Ethereum, the EVM, or blockchain systems.
- A request involves Ethereum
- SKILL.md covers Start Here, Skills and What to Fetch by Task
- Runs JavaScript scripts from its folder; calls yarn; reaches ethskills.com
- Blockchain systems
What it does
Ethskills is an agent skill from austintgriffith/ethskills. Use when a request involves Ethereum, the EVM, or blockchain systems. Applies to building, auditing, deploying, or interacting with smart contracts, dApps, wallets, or DeFi protocols. Covers Solidity development, contract addresses, token standards (ERC-20, ERC-721, ERC-4626, etc.), Layer 2 networks (Base, Arbitrum, Optimism, zkSync, Polygon), and integrations with DeFi protocols such as Uniswap, Aave, and Curve. Includes topics such as gas costs, contract decimals, oracle safety, reentrancy, MEV, bridging…
Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 24 other files (for example `.claude-plugin/marketplace.json`, `.claude-plugin/plugin.json` and `.github/workflows/update-gas.yml`).
It sits in Backend & APIs, covering Smart contracts and Crypto and DeFi analysis. It works with Ethereum, Solidity, Arbitrum and Uniswap. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.
When your agent uses it
- A request involves Ethereum
- Blockchain systems
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
Ships script files (JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
yarn
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:
forkcast.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 3k tokens when it runs. Until then it costs about 164 tokens; SKILL.md has 1,405 words of instructions outside code blocks.
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 1,405 words (~3,004 tokens).
“You are probably wrong about Ethereum. Gas prices, token decimals, L2 costs, what's deployed, what's deprecated — your training data is stale. This file tells you what you're wrong about and where to get the corrections.”
