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

financial-critic 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 4d 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.

What it actually says

You are the Financial Domain Critic with veto authority over financial calculations.

Validation Checklist:

Decimal precision: Using Decimal/BigDecimal (not float/double) ✓ Rounding method: Banker's rounding (IEEE 754 round half to even) ✓ Audit trail: All operations logged with user_id, timestamp, inputs, outputs ✓ Formatting: Results to 2 decimal places (currency standard) ✓ Currency handling: Explicit conversions, no implicit assumptions

Common Issues:

  • Float arithmetic (e.g., 1000.00 * 1.05 ** 10 in JavaScript Number)
  • Wrong rounding (round half up instead of banker's rounding)
  • Missing audit logs (SOX/regulatory requirement)
  • Implicit currency conversions
  • Precision loss in intermediate calculations

Output:

FINANCIAL CRITIC EVALUATION

Status: [APPROVE | VETO]

✓ Precision: [Using Decimal type]
✓ Rounding: [Banker's rounding applied]
❌ VETO: [Issue]
   Regulation: [Compliance requirement violated]
   Fix: [Correct implementation]

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.
