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 | $0.00057 | $0.00834 |
| Opus 5 | $0.00028 | $0.00417 |
| Sonnet 5 | $0.00011 | $0.00167 |
| Haiku 4.5 | $0.00006 | $0.00083 |
Grade A, and why
new-account-setup 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.
This is a copy
86% identical to storytelling — 137 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
New Account Setup
Step-by-step workflow for creating a synthetic account for a customer.
Step 1 — Identify the Customer
If you don't already have the customer UID:
list-customers (filter by name, email, or external_uid as needed)
get-customer uid=<customer_uid>
Note the customer's:
uid— needed when associating the accountpool_uids— the pools this customer already belongs tokyc_status— account creation may fail if KYC is not approvedstatus— customer must be active
Step 2 — Select an Account Type
List all available synthetic account types for the program:
get-synthetic-account-types
Each type has:
uid— thesynthetic_account_type_uidrequired at creationnameanddescription— what the account is forsynthetic_account_category— e.g.general,external_checking,external_savings
Choose the type that matches the intended use. If the user has not specified a type,
ask them or infer from context (e.g. "checking account" → external_checking category).
Step 3 — Select a Pool
List available pools:
list-pools
Choose the pool that:
- The customer already belongs to (their
pool_uidsfrom Step 1), or - Matches the intended product/program context
Note the pool uid — this becomes pool_uid at creation.
Step 4 — Check Product Eligibility (Optional)
If you want to confirm the customer is eligible for a product before opening an account:
list-products
list-customer-products (to see what the customer already has)
This step is informational — product eligibility is enforced by the API at creation time.
Step 5 — Determine Payment Rail Fields
Depending on the account type and use case, include the appropriate optional block:
ACH External Account
Include an ach block:
account_type—checkingorsavingscounterparty_name— name on the external accountrouting_numberandaccount_number— external bank details
Wire External Account
Include a wire block:
counterparty_name— name on the external account- Optionally
counterparty_bank_nameandcounterparty_bank_address
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.
