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 | $0.00013 | $0.05795 |
| Opus 5 | $0.00006 | $0.02898 |
| Sonnet 5 | $0.00003 | $0.01159 |
| Haiku 4.5 | $0.00001 | $0.00579 |
Grade A, and why
options-analysis 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 4d 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.

Options Analysis
⚠️ Data Verification — Do This Before Any Analysis
Before running any analysis, always retrieve the latest market data for the ticker:
- Fetch current price — use web search or ask the user for the live price, 52-week range, and market cap. Never assume a price from training data.
- Confirm key figures — recent earnings, revenue, key ratios (P/E, P/S, etc.) as applicable to this skill.
- State your data source — note where the numbers came from (e.g., "Google Finance, June 19 2026") at the top of the output.
- Flag stale data explicitly — if live data is unavailable, display this warning before proceeding:
⚠️ Live data unavailable. The following analysis uses training-data estimates which may be significantly out of date. Verify all prices and metrics before making any decisions.
Never silently substitute training-data estimates for current prices. When in doubt, ask the user to paste the latest quote.
Comprehensive analysis of options Greeks, implied volatility dynamics, strategy selection, and risk/reward frameworks for US-listed equity options. Designed to help identify optimal strategies based on market outlook, volatility environment, and underlying stock context.
Risk Disclaimer: Options involve significant leverage and can result in the loss of the entire premium paid or, for short options, losses substantially exceeding the initial credit received. This analysis is for educational and informational purposes only and does not constitute financial advice.
Analysis Framework
1. Options Basics and Context
Core Terminology
- Strike price: The price at which the option holder can buy (call) or sell (put) the underlying stock
- Expiration date: The date the option contract expires; American-style options can be exercised at any time before expiration
- Premium: The market price of the option contract (cost to buyer, credit received by seller)
- Contract: Represents 100 shares of the underlying stock
- ITM (In-the-Money): Call with strike < stock price; Put with strike > stock price — has intrinsic value
- ATM (At-the-Money): Strike approximately equal to current stock price
- OTM (Out-of-the-Money): Call with strike > stock price; Put with strike < stock price — only time value, no intrinsic value
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-analysis is a skill published in the GitHub repository yennanliu/InvestSkill (198 stars, last pushed yesterday), licensed MIT. It adds 13 tokens to every session and 5,795 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
