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 | $0.00027 | $0.00228 |
| Opus 5 | $0.00014 | $0.00114 |
| Sonnet 5 | $0.00005 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
invoice-chase 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 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.
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
Chase Overdue Invoices
Review overdue invoices and help collect payment.
Steps
- Call
invoice_listwith status=overdue - Call
finance_summaryfor context on total receivables
Output Format
Group invoices by urgency:
OVERDUE INVOICES — EUR [total]
CRITICAL (90+ days) — EUR X
- #INV-001 | Customer | EUR 1,500 | Due: 2026-04-15
WARNING (60-90 days) — EUR Y
- #INV-002 | Customer | EUR 800 | Due: 2026-05-20
ATTENTION (30-60 days) — EUR Z
- #INV-003 | Customer | EUR 2,200 | Due: 2026-06-10
Then ask: "Want me to send reminders for any of these?"
If yes, use invoice_send for each selected invoice.
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.

invoice-chase is a skill published in the GitHub repository Alessandro114/scala-mcp-server (2 stars, last pushed 16d ago), licensed MIT. It adds 27 tokens to every session and 228 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
