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 | $0.00000 | $0.00621 |
| Opus 5.5 | $0.00000 | $0.00248 |
| Sonnet 5.5 | $0.00000 | $0.00124 |
| Haiku 4.5 | $0.00000 | $0.00062 |
Grade A, and why
mcp_quiver 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.
How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tool Selection
| Intent | Tool |
|---|---|
| Congressional trades for a specific stock | get_congress_trades |

Multi-Step Workflows
Political-Financial Intelligence on a Stock
get_congress_trades— who in Congress is trading this stock?get_lobbying— how much is the company spending on lobbying?get_gov_contracts— does the company have government contracts?- For each active politician found in step 1:
get_politician_profile— deep dive
Politician Investigation
get_politician_profile— full profile with committees, donors, trading stats- For tickers in their portfolio:
get_congress_trades— detailed trade history per stock
Daily Scan / Ingestion
get_congress_trades_bulk— all recent congressional tradesget_lobbying_bulk— all recent lobbying recordsget_gov_contracts_bulk— all recent contract awards- Cross-reference: identify tickers that appear in multiple datasets

What ships with it
2 files 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.
