What it does

Greeks is an agent skill from staskh/trading_skills. Calculate option Greeks (delta, gamma, theta, vega) and implied volatility for specific options. Use when user asks about Greeks, delta, gamma, theta, vega, IV, or option sensitivity analysis.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/greeks.py`).

It sits in Business, Finance & HR. The repository describes itself as: Claude powered advisor system for option traders. The licence is MIT.

Requirements

What it can do on your machine

Read from SKILL.md and the folder at commit b71a74f. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Greeks loads about 539 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 164 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~50
When it runs · the whole SKILL.md, loaded when a task matches: ~539

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Option Greeks

Calculate Greeks for options using Black-Scholes model. Computes IV from market price via Newton-Raphson.

Instructions

Note: If uv is not installed or pyproject.toml is not found, replace uv run python with python in all commands below.

bash

uv run python scripts/greeks.py --spot SPOT --strike STRIKE --type call|put [--expiry YYYY-MM-DD | --dte DTE] [--price PRICE] [--date YYYY-MM-DD] [--vol VOL] [--rate RATE]

Arguments

--spot - Underlying spot price (required)
--strike - Option strike price (required)
--type - Option type: call or put (required)
--expiry - Expiration date YYYY-MM-DD (use this OR --dte)
--dte - Days to expiration (alternative to --expiry)
--date - Calculate as of this date instead of today (YYYY-MM-DD)
--price - Option market price (for IV calculation)
--vol - Override volatility as decimal (e.g., 0.30 for 30%)
--rate - Risk-free rate (default: 0.05)

Output

Returns JSON with:

spot - Underlying spot price
strike - Strike price
days_to_expiry - Days until expiration
iv - Implied volatility (calculated from market price)
greeks - delta, gamma, theta, vega, rho

Examples

bash

# With expiry date and market price (calculates IV)
uv run python scripts/greeks.py --spot 630 --strike 600 --expiry 2026-05-15 --type call --price 72.64

# With DTE directly
uv run python scripts/greeks.py --spot 630 --strike 600 --dte 30 --type call --price 40

# As of a future date
uv run python scripts/greeks.py --spot 630 --strike 600 --expiry 2026-05-15 --date 2026-03-01 --type call --price 50

Explain what each Greek means for the position.
