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 | $0.00072 | $0.00896 |
| Opus 5 | $0.00036 | $0.00448 |
| Sonnet 5 | $0.00014 | $0.00179 |
| Haiku 4.5 | $0.00007 | $0.00090 |
Grade A, and why
send-usdc 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sending USDC
Use the npx [email protected] send command to transfer USDC from the wallet to any Ethereum address or ENS name on Base.
Confirm wallet is initialized and authed
npx [email protected] status
If the wallet is not authenticated, refer to the authenticate-wallet skill.
Command Syntax
npx [email protected] send <amount> <recipient> [--chain <chain>] [--json]
Arguments
| Argument | Description |
|---|---|
amount |
Amount to send: '$1.00', '1.00', or atomic units (1000000 = $1). Always single-quote amounts that use $ to prevent bash variable expansion. If the number looks like atomic units (no decimal or > 100), treat as atomic units. Assume that people won't be sending more than 100 USDC the majority of the time |
recipient |
Ethereum address (0x...) or ENS name (vitalik.eth) |
Options
| Option | Description |
|---|---|
--chain <name> |
Blockchain network (default: base) |
--json |
Output result as JSON |
Input Validation
Before constructing the command, validate all user-provided values to prevent shell injection:
- amount: Must match
^\$?[\d.]+$(digits, optional decimal point, optional$prefix). Reject if it contains spaces, semicolons, pipes, backticks, or other shell metacharacters. - recipient: Must be a valid
0xhex address (^0x[0-9a-fA-F]{40}$) or an ENS name (^[a-zA-Z0-9.-]+\.eth$). Reject any value containing spaces or shell metacharacters.
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.

send-usdc is a skill published in the GitHub repository Octodamus/octodamus-core (1 stars, last pushed today), licensed MIT. It adds 72 tokens to every session and 896 once invoked, about $0.0004 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.
