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 | $0.00856 |
| Opus 5 | $0.00030 | $0.00428 |
| Sonnet 5 | $0.00012 | $0.00171 |
| Haiku 4.5 | $0.00006 | $0.00086 |
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 12d 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Authenticating with the Payments 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 USDC wallet balance |
npx [email protected] address |
Get wallet address |
npx [email protected] show |

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.
- 12d ago First seen · 89 lines · 60 tokens per session scan A 5d4525dc8d21
authenticate-wallet is a skill published in the GitHub repository Octodamus/octodamus-core (1 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 856 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 2026-08-31.
