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 | $0.00039 | $0.00523 |
| Opus 5 | $0.00019 | $0.00262 |
| Sonnet 5 | $0.00008 | $0.00105 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
invoice-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 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
[SKILL] invoice-manager [OBJ] Generate client-ready quotations and invoices, track payment status, and reconcile multi-currency earnings. Model the lifecycle as Client → Invoice → Payment, mirroring invoiceninja's entity graph, so every invoice traces to a client and every payment to an invoice.
[RULES]
- [REQ] Entity model: always anchor an Invoice to a Client (name, email, currency, locale). A Payment references an Invoice; never record income without a linked invoice.
- [REQ] Quotation → Invoice: a quotation is a draft offer; on acceptance convert it to an Invoice with line items (description, qty, unit price, tax), due date, and payment terms.
- [CMD] Context7 IDs:
invoiceninja/invoiceninja— extract the Client→Invoice→Payment entity model, recurring invoices, and multi-currency handling. - [REQ] Multi-currency: support USD, SAR, AED, EGP (Arabic-platform clients). Store the invoice currency; show the USD-equivalent using a configurable rate. Never hardcode a rate — ask or read from config.
- [REQ] RTL Arabic invoices: when client locale is ar, render dir="rtl", Arabic labels (فاتورة / عميل / المبلغ / تاريخ الاستحقاق), and Arabic or Western numerals per preference.
- [REQ] Payment tracking: record status (draft/sent/paid/overdue/partial), send reminders for overdue, and reconcile against received payments. Keep a running aging report.
- [REQ] Free-first: Invoice Ninja (free self-host / free tier) is the default engine; closed billing tools only as parity.
- [REQ] Storage: persist clients/invoices/payments via
StorageFactory; never log client PII or payment credentials.
[PROHIBIT]
- No sending an invoice or marking a payment received without explicit user approval.
- No fabricating payment records or balances to mask overdue accounts.
- No storing card/bank credentials or PII outside the approved storage backend.
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-manager is a skill published in the GitHub repository m3taz-ahmed/ai-globals (5 stars, last pushed 3d ago), licensed MIT.
