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 | $0.00068 | $0.01335 |
| Opus 5 | $0.00034 | $0.00668 |
| Sonnet 5 | $0.00014 | $0.00267 |
| Haiku 4.5 | $0.00007 | $0.00134 |
Grade A, and why
trade 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trading Tokens
Use the npx [email protected] trade command to swap tokens on Base network via the CDP Swap API. You must be authenticated to trade.
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] trade <amount> <from> <to> [options]
Arguments
| Argument | Description |
|---|---|
amount |
Amount to swap (see Amount Formats below) |
from |
Source token: alias (usdc, eth, weth) or contract address (0x...) |
to |
Destination token: alias (usdc, eth, weth) or contract address (0x...) |
Amount Formats
The amount can be specified in multiple formats:
| Format | Example | Description |
|---|---|---|
| Dollar prefix | '$1.00', '$0.50' |
USD notation (decimals based on token) |
| Decimal | 1.0, 0.50, 0.001 |
Human-readable with decimal point |
| Whole number | 5, 100 |
Interpreted as whole tokens |
| Atomic units | 500000 |
Large integers treated as atomic units |
Auto-detection: Large integers without a decimal point are treated as atomic units. For example, 500000 for USDC (6 decimals) = $0.50.
Decimals: For known tokens (usdc=6, eth=18, weth=18), decimals are automatic. For arbitrary contract addresses, decimals are read from the token contract.
Options
| Option | Description |
|---|---|
-c, --chain <name> |
Blockchain network (default: base) |
-s, --slippage <n> |
Slippage tolerance in basis points (100 = 1%) |
--json |
Output result as JSON |
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.

trade is a skill published in the GitHub repository Octodamus/octodamus-core (1 stars, last pushed yesterday), licensed MIT. It adds 68 tokens to every session and 1,335 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.
