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 | $0.00128 | $0.01757 |
| Opus 5 | $0.00064 | $0.00879 |
| Sonnet 5 | $0.00026 | $0.00351 |
| Haiku 4.5 | $0.00013 | $0.00176 |
Grade A, and why
alphagbm-greeks 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 12d 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.
This is a copy
100% identical to alphagbm-greeks — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

AlphaGBM Greeks
Prerequisites

ALPHAGBM_API_KEY(formatagbm_xxxx...). - Base URL: Default
https://alphagbm.zeabur.app. Override with envALPHAGBM_BASE_URL.
What This Skill Does
Provides a comprehensive Greeks dashboard for any single option contract or multi-leg position. Calculates first-order and second-order sensitivities, and generates scenario heatmaps showing how Greeks change as price and IV move.
Greeks Covered
| Greek | Order | What It Measures |
|---|---|---|
| Delta | 1st | Price sensitivity -- how much does the option move per $1 in the underlying? |
| Gamma | 1st | Delta sensitivity -- how fast does delta change? (acceleration) |
| Theta | 1st | Time decay -- how much value does the option lose per day? |
| Vega | 1st | IV sensitivity -- how much does the option move per 1% change in IV? |
| Rho | 1st | Interest rate sensitivity -- how much does the option move per 1% rate change? |
| Charm | 2nd | Delta decay -- how does delta change as time passes? (delta-theta cross) |
| Vanna | 2nd | Delta-vol cross -- how does delta change as IV moves? |
| Volga | 2nd | Vega convexity -- how does vega change as IV moves? |
Position-Level Analysis
For multi-leg positions, the skill aggregates Greeks across all legs and shows:
- Net Greeks: Total delta, gamma, theta, vega for the combined position
- Greeks per unit of capital: Normalized by margin requirement or net debit
- Risk concentration: Which leg contributes most to each Greek

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.

alphagbm-greeks is a skill published in the GitHub repository leecyno1/boutique-skills (5 stars, last pushed today), licensed MIT. It adds 128 tokens to every session and 1,757 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to alphagbm-greeks, differing in 0 lines, and is treated as a copy.
