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 | $0.00114 | $0.04427 |
| Opus 5 | $0.00057 | $0.02214 |
| Sonnet 5 | $0.00023 | $0.00885 |
| Haiku 4.5 | $0.00011 | $0.00443 |
Grade A, and why
contract-to-billing 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Contract to Billing
Reads a customer document (PO, contract, quote), extracts line items with AI, and creates a fully populated invoice in Airwallex Billing.
When to use
- User uploads or references a purchase order, contract, quote, or billing document
- User asks to "create an invoice" from a document
- User wants to extract billing details and set up products/prices/customers
- User says "bill this customer" with a document attached
When NOT to use
This skill only covers Billing-domain operations — invoices (list, create, retrieve, finalize, void, mark-as-paid, plus line-item add / update / delete / list), products (list, create), prices (list, create), customers (list, retrieve, create, update), subscriptions (create, list items), coupons (list, create, update), meters (list, create, update), payment sources (list), and billing transactions (list, retrieve). Credit notes follow create → line-items add → finalize — if the operation is not exposed on the current surface, direct the user to the Airwallex Dashboard.
If the task requires capabilities outside this domain, stop — this is the wrong skill. Redirect the user:
- Wire transfers / payouts → not yet available (use Airwallex Dashboard)
- Setting up suppliers / beneficiaries → beneficiary-creation skill
- FX conversions, balances, treasury → manage-cashflow skill
- Provisioning corporate cards → card-provisioning skill
- Ad-hoc tasks outside billing workflow → awx-best-practices skill (fallback)
Non-negotiables
Terminology
- Invoices = receivables (money in). Issued BY the user TO their customers. Never say "obligation" for invoices.
- Invoice lifecycle. DRAFT → add line items → finalize → FINALIZED (immutable). To correct after finalize: void → create new.
- Products & prices. Every invoice line item needs a product. For document-specific ad-hoc fees (shipping, handling, setup fees, tax), always use the inline price mechanism (see Path B in Workflow) with a newly created product rather than matching existing fee products — fee amounts and descriptions vary per order. Only reuse existing products for the core goods/services sold (e.g., "Widget Alpha").
- Invoice vs Subscription. One-time quote → Invoice. Recurring terms → Subscription. Choose before creating.
- ONE_OFF vs RECURRING. Baked in at price creation — cannot flip later.

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.

contract-to-billing is a skill published in the GitHub repository airwallex/airwallex-marketplace (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 114 tokens to every session and 4,427 once invoked, about $0.0006 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 2026-08-30.
Other skills, from other repositories
marketplace-purchase-vetting
Use this when the user asks whether a local listing is a scam, "too good to be true," worth looking at, or a good deal. Also use this when he asks you to find options — search/discover candidates, then vet the best ones. The goal is not a generic buying guide; it is a practical risk read with clear next steps.
payout-split-management
Manage complex payout splits for marketplaces and platforms with seller disbursements, commission calculation, tax withholding, and 1099 reporting.
a2a-commerce
Agent-to-agent payments, marketplace, identity, and trust scoring. Escrow is simulated via an in-memory SQLite ledger — no real funds are held. Stripe integration handles actual payment processing.
asc-ppp-pricing
Set territory-specific pricing for subscriptions and in-app purchases using current asc setup, pricing summary, price import, and price schedule commands. Use when adjusting prices by country or implementing localized PPP strategies.
stripe
Stripe API integration with managed OAuth. Manage customers, subscriptions, invoices, products, prices, and payments. Use this skill when users want to process payments, manage billing, or handle subscriptions with Stripe. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).…
finance-investor-relations
An investor-relations tool for preparing pitch decks and three-year financial models for fundraising. An IR, or investor-relations, deck explains a company to potential investors, while the model covers sales, profit, cash flow, and valuation.
