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 | $0.00118 | $0.01527 |
| Opus 5 | $0.00059 | $0.00763 |
| Sonnet 5 | $0.00024 | $0.00305 |
| Haiku 4.5 | $0.00012 | $0.00153 |
Grade A, and why
us-stock 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 9d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
U.S. Stock Market Quote Lookup
Data Source
Google Finance (browser_use navigate + get_text): no API or login required; returns structured data.
Query Process
Step 0: Set the Desktop Viewport
browser_use set_viewport viewport_width: 1280 viewport_height: 800
Google Finance distinguishes between desktop and mobile versions mainly by viewport width. Setting a wide enough viewport is sufficient to retrieve the full data. This method is compatible across Android and iOS and is not affected by differences in UA enumeration values.
Step 1: The Three Major Indices (in parallel, with up to 3 tabs open at once)
First, open the S&P 500 in the default tab 0:
browser_use navigate https://www.google.com/finance/quote/.INX:INDEXSP?hl=en
browser_use get_text
Then create two new tabs and open the Dow and Nasdaq:
browser_use new_tab
browser_use navigate https://www.google.com/finance/quote/.DJI:INDEXDJX?hl=en
browser_use get_text
browser_use new_tab
browser_use navigate https://www.google.com/finance/quote/.IXIC:INDEXNASDAQ?hl=en
browser_use get_text
Use get_text to extract data from each tab. Extract the key fields: current price, point change, percentage change, open/high/low, and previous close.
Step 2: VIX Fear Index (navigate in an existing tab; do not open a new tab)
browser_use navigate https://www.google.com/finance/quote/VIX:INDEXCBOE?hl=en
browser_use get_text
Key fields: current price, percentage change, previous close, 52-week high/low.
VIX alert thresholds: <15 complacency / 15-20 normal / 20-25 caution / 25+ panic.
Core assessment: VIX absolute level + the day's direction of change. Distinguish a mild VIX rise caused by an individual-stock event such as Broadcom from a VIX spike caused by systemic panic.
Step 3: Magnificent 7 (rotate through the existing 3 tabs; do not open new tabs)
There is no dedicated 4th tab for VIX. First navigate the default/latest tab to NVDA, extract with get_text, then navigate that same tab to the next stock.
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.
