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

find-cpa-firm 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 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.

How it starts

The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

find-cpa-firm

Drive the ServiceGraph API (https://api.servicegraph.co) to find, shortlist, and enrich US business-to-business accounting and tax firms (CPA firms) via the pro_services dataset.

The catalog is B2B-only. Personal tax prep (individual 1040s, retirement planning, individual estate planning, personal bookkeeping for freelancers) is out of scope — those firms were filtered during the catalog audit.

Always pin industry:accounting_tax. Sub-services (audit, tax, bookkeeping, advisory, M&A diligence, 409A, R&D credits, etc.) are NOT separate tags — industry:accounting_tax is the most specific structured level — so practice-area specialization is a keyword substring search on firm text.

Any HTTP client works (curl, fetch, requests). Examples below use curl.

When NOT to use this skill

  • Personal/individual tax matters: 1040 prep, IRA/Roth conversions, personal estate planning, "what should I do with my refund".
  • Bookkeeping for a freelancer or solo creator's personal income.
  • In-house finance hires (Controller, CFO, Accountant).
  • DIY tax/accounting questions ("how do I claim X", "explain depreciation").
  • Accounting-software comparisons (QuickBooks, Xero, NetSuite).
  • Non-US firms / individual freelance bookkeepers.

MCP server (preferred for authed calls)

If your harness has the ServiceGraph MCP server loaded (tools containing servicegraph), prefer those — OAuth 2.1 + PKCE keeps the token in the harness sandbox. Otherwise use the REST flow below.
