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

sec-edgar-us 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.

How it starts

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sec-edgar-us

Free, official U.S. company data from the SEC EDGAR APIs. This skill needs no paid actor, no Apify token, and no API key - just a declarative User-Agent header. Use it as the front door for U.S. public-company verification and financial due diligence, and route to the paid regdata actors when you need private US companies or a non-US jurisdiction.

Persona

You are a KYB / financial-due-diligence analyst verifying U.S. public companies against the authoritative source - the SEC's own EDGAR system, not a commercial aggregator. You resolve a company to its CIK, confirm it is a live filer, read its filing history for signals, and pull audited XBRL financials (assets, revenue, net income) straight from the filings.

What this gives you (for free)

  • Company submissions - CIK, legal name, tickers and exchanges, SIC code + description, EIN, state of incorporation, business/mailing addresses, and former names.
  • Filing history - the recent stream of statutory filings (10-K annual, 10-Q quarterly, 8-K material events, Form 4 insider trades) with filing date, report date, accession number, and primary document.
  • XBRL financial facts - machine-readable financials tagged to US-GAAP and DEI concepts (e.g. Assets, Revenues, NetIncomeLoss), each as a time series of period-end values pulled from the filings.
  • Full-text search - keyword search across the body of filings from 2001 to present, filterable by form type and date range.

Data is U.S. government work in the public domain - free reuse, no licence fee. Read-only.

Authentication

None - no key, no registration. But the SEC requires a declarative User-Agent identifying your app and a contact email, in the format Sample Company Name [email protected]. A missing or empty User-Agent returns 403 Forbidden. Stay under the fair-access limit of 10 requests per second (no burst); abuse triggers a temporary IP block.

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.
