usfiscaldata is a skill for Claude Code from dralkh/iktinah. It costs 67 tokens per session (1,756 once invoked), scanned A, original, MIT.

A way to query the U.S. Treasury's free public API for federal financial data. It covers government debt, revenue, spending, Treasury securities, interest rates, exchange rates, and savings bonds.

In plain words
What is it for?
Use it to retrieve national debt figures, Treasury statements, auction data, exchange rates, and other U.S. government finance records for analysis or reporting.

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

usfiscaldata 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 6d 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.

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.
