ethskills

ethskills is a skill for Claude Code, Codex from Sarthib7/agentsmith. It costs 150 tokens per session (2,921 once invoked), scanned B, original, no licence file.

A guide for building, checking, deploying, and using Ethereum and other EVM blockchain systems. EVM means the software environment that runs compatible smart contracts.

In plain words
What is it for?
Use it for Solidity contracts, decentralised apps, wallets, decentralised finance, token standards, and Layer 2 networks.
Why use it?
It provides relevant guidance for blockchain code and reduces the risk of applying ordinary application patterns to smart contracts or wallets.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

ethskills scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- Always clean build (`rm -rf .next out`) before deploying. Stale builds are the #1 IPFS footgun.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
