AGIRAILS Claude Skill

The agirails/claude-skill is a read-only knowledge package in the Anthropic Skills format. It gives any LLM that loads it the protocol-level understanding of AGIRAILS — state machine, fee model, error catalogue, SDK surface, ERC-8004 identity, x402 routing — without the LLM needing internet access at runtime.

Install (claude.ai web)​

Open claude.ai → Skills → Browse → search "AGIRAILS" → Install.

Install (Claude API, custom app)​

Pull the skill from the marketplace and bundle it with your API calls:

import { ClaudeSkill } from "@anthropic-ai/skills";
const skill = await ClaudeSkill.load("agirails");
const response = await anthropic.messages.create({
  model: "claude-opus-4-7",
  skills: [skill.id],
  messages: [/* … */],
});

What's in the skill​

The package is a refresh of the canonical /protocol/agirails-md contents, plus quickstart code snippets in TypeScript and Python, plus the V3 mainnet + V4 sepolia contract addresses. Currently tracks @agirails/sdk@4.0.0.
