three.ws: Skill for Claude Code

.agents/skills/authenticate-wallet/SKILL.md

authenticate-wallet is a skill for Claude Code from nirholas/three.ws. It costs 60 tokens per session (886 once invoked), scanned A, original, Apache-2.0.

A procedure for signing in to an Agentic Wallet with an email address and a one-time verification code. The wallet must be signed in before sending, trading, or funding it.

In plain words
What is it for?
Use it to start and complete wallet login, handle email one-time passwords, and recover from authentication failures.
Why use it?
It provides the required authentication step when the wallet is not connected or an operation reports a sign-in error. It also checks email input before building commands.

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 A, and why

authenticate-wallet 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 14d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Authenticating with the Agentic Wallet

When the wallet is not signed in (detected via npx awal status or when wallet operations fail with authentication errors), use the npx awal CLI to authenticate.

If you have access to email, you can authenticate the wallet yourself, otherwise you'll need to ask your human to give you an email address and to tell you the OTP code they receive.

Authentication Flow

Authentication uses a two-step email OTP process:

Step 1: Initiate login

npx [email protected] auth login <email>

This sends a 6-digit verification code to the email and outputs a flowId.

Step 2: Verify OTP

npx [email protected] auth verify <otp>

Use the 6-digit code from the user's email to complete authentication. The flow ID from step 1 is saved automatically to a local file; you do not pass it as an argument. If you have the ability to access the user's email, you can read the OTP code, or you can ask your human for the code.

Input Validation

Before constructing the command, validate all user-provided values to prevent shell injection:

  • email: Must match a standard email format (^[^\s;|&]+@[^\s;|&]+$). Reject if it contains spaces, semicolons, pipes, backticks, or other shell metacharacters.
  • otp: Must be exactly 6 digits (^\d{6}$).

Do not pass unvalidated user input into the command.

Checking Authentication Status

npx [email protected] status

Displays wallet server health and authentication status including wallet address.

Example Session

# Check current status
npx [email protected] status

# Start login (sends OTP to email)
npx [email protected] auth login [email protected]
# Output: flowId: abc123...

# After user receives code, verify (flow ID saved automatically)
npx [email protected] auth verify 123456

# Confirm authentication
npx [email protected] status

Available CLI Commands

Command Purpose
npx [email protected] status Check server health and auth status
npx [email protected] auth login <email> Send OTP code to email, returns flowId
npx [email protected] auth verify <otp> Complete authentication with OTP code
npx [email protected] balance Get balances across Base, Polygon, and Solana (use --chain for a single chain)
npx [email protected] address Get wallet address
npx [email protected] show Open the wallet companion window

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.
