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 | $0.00110 | $0.07561 |
| Opus 5 | $0.00055 | $0.03780 |
| Sonnet 5 | $0.00022 | $0.01512 |
| Haiku 4.5 | $0.00011 | $0.00756 |
Grade A, and why
account-opening-workflow 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 11d 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.

Account Opening Workflow
Core Concepts
Account Type Determination and Registration
Account type determination is the foundational decision in the account opening workflow. The registration type dictates the document requirements, approval gates, tax treatment, titling rules, and custodian submission path. Operations teams must maintain a comprehensive account type matrix that maps each registration type to its downstream processing requirements.
Individual and joint registration types:
- Individual — single natural person as owner; titled in the individual's legal name; SSN as TIN; simplest registration and the baseline for all account opening processes
- Joint Tenants with Right of Survivorship (JTWROS) — two or more co-owners with equal, undivided interest; on death of one owner, the surviving owner(s) automatically inherit the deceased owner's share without probate; all owners must sign account opening documents; titled as "John Smith and Jane Smith JTWROS"
- Tenants in Common (TIC) — two or more co-owners with specified ownership percentages (need not be equal); on death, the deceased owner's share passes to their estate, not to the surviving co-owner(s); ownership percentages must be recorded and may affect tax reporting; titled as "John Smith and Jane Smith TIC"
- Community Property — available only in community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin); assets acquired during marriage are jointly owned; specific titling and tax implications vary by state; some custodians treat community property accounts differently from other joint account types
- Community Property with Right of Survivorship — a hybrid available in some community property states that combines community property tax treatment with automatic survivorship; not all custodians support this registration type
Trust registration types:
- Revocable (living) trust — grantor retains control and can modify or revoke the trust; typically titled as "John Smith, Trustee of the Smith Family Trust dated 01/15/2020"; grantor's SSN is often used as TIN; account opening requires trust certification or relevant pages of the trust agreement showing trust name, date, trustees, and investment powers
- Irrevocable trust — grantor has permanently relinquished control; separate tax entity requiring its own EIN; beneficial ownership certification required under FinCEN CDD Rule; titled in the trust's legal name with trustee designation; requires more extensive documentation including the full trust agreement or comprehensive trust certification
- Testamentary trust — created by a will and comes into existence upon the grantor's death; requires letters testamentary, death certificate, and court-certified copy of the will provisions creating the trust; account opening is typically manual due to the complexity and variation in court documentation
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

account-opening-workflow is a skill published in the GitHub repository JoelLewis/finance_skills (184 stars, last pushed 1mo ago), licensed MIT. It adds 110 tokens to every session and 7,561 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.
