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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00035 | $0.00312 |
| Opus 5 | $0.00017 | $0.00156 |
| Sonnet 5 | $0.00007 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
scalable-capital 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 10d 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
Scalable Capital broker tools
Use the sc_* tools to answer questions about the user's Scalable Capital
broker account. Pick by intent:
- Account value / cash / performance →
sc_overview - Positions and market values →
sc_holdings - Trade history (tax, reconciliation) →
sc_transactions(filter by date/ISIN/type) - A single transaction's detail →
sc_transaction - Allocation / sector / region exposure →
sc_analytics - Live price of one security →
sc_quote - Find a security →
sc_search - News for a security →
sc_security_news
Rules
- Read-only. These tools never place trades or change the account. If asked
to buy/sell/set alerts, say it's out of scope and point to the
scCLI. - Always fetch; never quote prices or values from memory or earlier in the chat — markets move. Call the tool again.
- Responses may be up to ~5 minutes stale (server-side cache). For a fresh-to-the-second number, say so or note the staleness.
- Not financial advice. Report the data; don't recommend trades.
- On an error mentioning login/session, tell the user to run
sc login.
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.

scalable-capital is a skill published in the GitHub repository ratulotron/sc-mcp (0 stars, last pushed 2mo ago), licensed MIT.
