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 | $0.00063 | $0.00350 |
| Opus 5.5 | $0.00025 | $0.00140 |
| Sonnet 5.5 | $0.00013 | $0.00070 |
| Haiku 4.5 | $0.00006 | $0.00035 |
Grade A, and why
options-check 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 2d 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
Options check
Use the HPSILab connector's tools. If they are not available, tell the user to connect HPSILab (https://hpsilab.com/connect) and stop; never invent figures.
- Get one ticker per call (convert company names yourself; ask if ambiguous).
- Call
get_iv_radarfor how expensive options are: at-the-money and 30-day implied volatility, IV rank and percentile, the 25-delta risk reversal (skew), the squeeze score and the regime. - Call
get_option_pressurefor the nearest weekly or monthly expiry: max pain, the gamma wall, the call and put walls, the weekly expected move, the likely weekly high, the expiry close range and the squeeze target. - Present one compact table with the figures, the expiry each one refers to and the data date. Then explain in plain words: what the IV level and rank mean for option prices, which way the skew leans, and which strikes act as support or resistance.
- If a field comes back unavailable (for example open interest outside market hours), say so and quote the tool's reason instead of estimating it.
These describe how the options market is priced and positioned. They are not a price target or a directional call; say so if the user treats them that way. Do not recommend a trade.
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.

options-check is a skill published in the GitHub repository haiyunsky/hpsilab-quant-finance-mcp (1 stars, last pushed 2d ago), licensed MIT. It adds 63 tokens to every session and 350 once invoked, about $0.0003 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 2026-10-25.
