ccxt: Skill for Claude Code

.agents/skills/query-token-audit/SKILL.md

query-token-audit is a skill for Claude Code, Codex from ccxt/ccxt. It costs 62 tokens per session (1,494 once invoked), scanned A, original, MIT.

A token-security checker for cryptocurrency tokens and their smart contracts, which are programs running on blockchains. It looks for scams, honeypots, dangerous contract functions, trading risks, and unusual buy or sell taxes on BSC, Base, Solana, and Ethereum.

In plain words
What is it for?
Use it to check whether a token may be a scam, whether selling could be blocked, whether the contract has risky controls, and whether its trading taxes look unusual.
Why use it?
It helps identify risks before buying or swapping a token. This reduces the need to judge an unfamiliar contract from its name or marketing alone.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

query-token-audit scanned grade A with 1 finding 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 1mo 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.
