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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.00576 |
| Opus 5.5 | $0.00018 | $0.00230 |
| Sonnet 5.5 | $0.00009 | $0.00115 |
| Haiku 4.5 | $0.00005 | $0.00058 |
Grade A, and why
expense-report 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 8d 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
Generate a comprehensive expense report for the user:
Step 1: Gather data
- Call
search_transactionsfor the specified period (default: last month) - Filter for outgoing transactions (expenses only, exclude income)
- Call
get_company_balancefor current balance context
Step 2: Categorize and group
Group expenses by bookkeeping category. For each category show:
- Category name
- Total amount (in the company's currency)
- Number of transactions
- Percentage of total expenses
Present as a ranked list, largest category first.
Step 3: Top vendors
List the top 10 vendors/payees by total spend:
- Vendor name
- Total amount
- Number of transactions
- Average transaction amount
Step 4: Trends and insights
If the user asks for a longer period (quarter or year), provide:
- Month-over-month comparison of total expenses
- Categories that increased or decreased significantly
- Recurring vs. one-time expenses
- Largest single transactions in the period
Step 5: Comparison (if possible)
If data is available for the previous equivalent period:
- Total expenses this period vs. last period
- Percentage change
- Categories with the biggest increase/decrease
- Flag any unusual or new expense categories
Presentation format
Structure the report clearly:
Expense Report: [Period]
========================
Total Expenses: X,XXX.XX [currency]
By Category:
1. [Category] X,XXX.XX [currency] (XX%) [N transactions]
2. [Category] XXX.XX [currency] (XX%) [N transactions]
...
Top Vendors:
1. [Vendor] X,XXX.XX [currency] [N transactions]
2. [Vendor] XXX.XX [currency] [N transactions]
...
Key Insights:
- [Notable finding]
- [Notable finding]
Keep amounts in the company's currency (EUR in Germany, PLN in Poland) and label it. Use clear formatting for readability. Offer to drill down into any specific category if the user wants more detail.
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.
