Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00311 |
| Opus 5 | $0.00008 | $0.00156 |
| Sonnet 5 | $0.00003 | $0.00062 |
| Haiku 4.5 | $0.00002 | $0.00031 |
Grade A, and why
Billing Manager 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 2d 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
Billing Manager
Take control of billing operations with workflows for invoice generation, payment tracking, and subscription management. Maintain healthy cash flow with timely invoicing and proactive collection.
Core Workflows
Workflow 1: Invoice Generation
- Gather Billables - Collect billable items, hours, or usage
- Apply Pricing - Calculate amounts based on rate cards
- Add Taxes - Apply appropriate tax rates
- Generate Invoice - Create professional invoice
- Track Status - Monitor open, paid, overdue
Workflow 2: Subscription Billing
- Setup - Configure plan, billing cycle, terms
- Recurring Charges - Process automatic billing
- Failed Payment Handling - Retry logic and dunning
- Renewal Notices - Send reminders
Quick Reference

|---|---|
| Create invoice | "Generate invoice for [customer]" |
| Check status | "Show outstanding invoices" |
| Process subscription | "Bill [customer] subscription" |
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.
