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 | $0.00139 | $0.03338 |
| Opus 5.5 | $0.00056 | $0.01335 |
| Sonnet 5 | $0.00028 | $0.00668 |
| Haiku 4.5 | $0.00014 | $0.00334 |
Grade A, and why
fsc-data-model 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 4d 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 — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FSC Data Model
Activate this skill when a practitioner needs to understand, design, or query the Financial Services Cloud (FSC) data model — covering the managed-package deployment with FinServ__ namespace objects and the platform-native Core FSC deployment using standard objects with no namespace. The skill covers the full object hierarchy from financial accounts through household relationships to rollup aggregation.
Before Starting
Gather this context before working on anything in this domain:
- Deployment type: Is the org using managed-package FSC (check Setup > Installed Packages for "Financial Services Cloud" or "Salesforce Industries") or Core FSC (platform-native, standard objects, no
FinServ__prefix)? This determines every object name and SOQL query used. - Person Accounts: Is Person Accounts enabled? FSC relies on Person Accounts to represent individual clients. Without it, the household and client relationship model does not work as documented.
- Rollup awareness: Practitioners assume native Salesforce roll-up summary fields aggregate financial data to household accounts. They do not. FSC uses its own async rollup engine configured in FSC Admin settings.
- Core FSC vs managed-package cutover: Orgs that went live before Winter '23 are almost certainly on managed-package FSC. New orgs provisioned after Winter '23 should evaluate Core FSC before defaulting to managed-package.
Core Concepts
Managed-Package FSC vs. Core FSC
FSC was originally delivered as a managed package under the FinServ__ namespace. Every custom object, field, and relationship carries that prefix: FinServ__FinancialAccount__c, FinServ__FinancialHolding__c, etc. Starting with Winter '23, Salesforce began shipping a platform-native version called Core FSC. Core FSC uses standard (no-namespace) objects: FinancialAccount, FinancialHolding, FinancialGoal. Core FSC eliminates package upgrade dependencies and gives full Metadata API control, but it is a different deployment architecture that cannot be retrofitted onto an existing managed-package org without migration work.
What ships with it

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.

fsc-data-model is a skill published in the GitHub repository skillmds/skillmd (1 stars, last pushed yesterday), licensed MIT. It adds 139 tokens to every session and 3,338 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-09-19.
