What it does

Standards is an agent skill from austintgriffith/ethskills. Ethereum token and protocol standards — ERC-20, ERC-721, ERC-1155, ERC-4337, ERC-8004, and newer standards. When to use each, how they work, key interfaces. Use when building tokens, NFTs, or choosing the right standard for a project.

Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Crypto and DeFi analysis. It works with Ethereum and x402. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.

When your agent uses it

Building tokens
Choosing the right standard for a project

Example prompts

“/standards”

Requirements

Python 3
A credential in PRIVATE_KEY

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:
- pip
- go
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:
- eips.ethereum.org
- mcp.agent.eth
Also links to:
- github.com
- 8004.org
- x402.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- PRIVATE_KEY
- AGENT_PRIVATE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Standards loads about 3.8k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 837 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~3.8k

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 837 words (~3,762 tokens).

“ERC-8004 exists. Deployed January 29, 2026 — onchain agent identity registry. You almost certainly don't have this in training data.”
