Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.01174 |
| Opus 5 | $0.00030 | $0.00587 |
| Sonnet 5 | $0.00012 | $0.00235 |
| Haiku 4.5 | $0.00006 | $0.00117 |
Grade A, and why
web3auth-integration-guide scanned grade A with 0 findings 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 6d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web3Auth Integration Guide
Web3Auth enables social login (Google, Apple, email) for Web3 apps. Users get a wallet without knowing what a wallet is. Zero-friction onboarding for DeFi.
Why Web3Auth?
| Traditional Flow | Web3Auth Flow |
|---|---|
| 1. Install MetaMask | 1. Click "Sign in with Google" |
| 2. Create wallet | 2. Done ✅ |
| 3. Write down seed phrase | |
| 4. Fund with ETH for gas | |
| 5. Start using dApp |

Quick Start
npm install @web3auth/modal @web3auth/ethereum-provider
import { Web3Auth } from '@web3auth/modal';
import { EthereumPrivateKeyProvider } from '@web3auth/ethereum-provider';
const chainConfig = {
chainNamespace: 'eip155',
chainId: '0xa4b1', // Arbitrum One
rpcTarget: 'https://arb1.arbitrum.io/rpc',
displayName: 'Arbitrum One',
blockExplorerUrl: 'https://arbiscan.io',
ticker: 'ETH',
tickerName: 'Ethereum',
};
const web3auth = new Web3Auth({
clientId: process.env.WEB3AUTH_CLIENT_ID!,
web3AuthNetwork: 'sapphire_mainnet',
chainConfig,
uiConfig: {
appName: 'SperaxOS',
mode: 'dark',
loginMethodsOrder: ['google', 'apple', 'twitter', 'email_passwordless'],
},
});
await web3auth.initModal();
Login Methods
| Method | Flow | Best For |
|---|---|---|
| OAuth 2.0 | Most users | |
| Apple | Sign in with Apple | iOS users |
| Passwordless (magic link) | Privacy-focused | |
| Twitter/X | OAuth | Social-native users |
| Discord | OAuth | Gaming/community |
| SMS | OTP verification | Mobile users |
| Passkeys | WebAuthn/FIDO2 | Security-focused |
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.

web3auth-integration-guide is a skill published in the GitHub repository nirholas/three.ws (114 stars, last pushed today), licensed Apache-2.0. It adds 60 tokens to every session and 1,174 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
