Claude for Financial Services is a collection of agents, skills, commands, plugins, and data connectors for investment banking, equity research, private equity, and wealth-management workflows. Financial professionals use it to draft models, memos, research notes, and reconciliations for review by qualified people. The catalogue contains components from these workflows, including agents, skills, plugins, commands, and instructions.
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 | $0.00046 | $0.00350 |
| Opus 5.5 | $0.00018 | $0.00140 |
| Sonnet 5.5 | $0.00009 | $0.00070 |
| Haiku 4.5 | $0.00005 | $0.00035 |
Grade A, and why
variance-commentary 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 2mo 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
Variance commentary
Given current-period actuals, prior-period actuals, and budget for the same scope, produce a commentary table.
Threshold
Flag a line for commentary if either is true:
- Absolute variance ≥ the firm's materiality threshold (use the provided value; default 5% of the line or a fixed floor, whichever is greater)
- The line is on the "always comment" list (revenue, headcount cost, cash)
For each flagged line
| Column | Content |
|---|---|
| Line | Account or caption |
| Current / Prior / Budget | The three values |
| Δ vs prior and Δ vs budget | Amount and % |
| Driver | One sentence explaining the movement from underlying activity — not a restatement of the number |
A driver explains why, not what: "Cloud spend up $1.2M on incremental GPU reservations for the May launch" — not "Cloud spend increased $1.2M (18%)."
Sourcing the driver
Look at the activity behind the line (journal-source breakdown, vendor mix, headcount delta, volume × rate) via the internal-gl MCP. If the driver isn't clear from the data, write "driver unclear — flag for controller" rather than inventing one.
Output
The commentary table plus a short narrative (3–5 sentences) summarizing the period's biggest movers.
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.
