Read-onlyIdempotent

Compute option prices, Greeks, and implied volatility using Black-Scholes, binomial tree, and other models. Supports multiple tickers.

Instructions

Option pricing and Greeks (Black-Scholes model, binomial tree, delta, gamma, theta, vega, rho, implied volatility). Requires tickers='AAPL' — use comma-separated values for multiple tickers.

Available indicators: get_asian_option, get_barrier_option, get_binary_option, get_binomial_model, get_bjerksund_stensland, get_black_scholes_model, get_charm, get_color, get_delta, get_dual_delta, get_dual_gamma, get_epsilon, get_gamma, get_garman_kohlhagen, get_implied_volatility, get_lambda, get_monte_carlo_option_price, get_option_chains, get_partial_derivative, get_put_call_parity, get_rho, get_risk_neutral_density, get_speed, get_stock_price_simulation, get_strategy_payoff, get_theta, get_ultima, get_vanna, get_vega, get_vera, get_veta, get_volatility_surface, get_vomma, get_zomma.

Name	Required	Description	Default
`legs`	No	Value for legs. Leave unset to use the default of the indicator you selected. Required by: get_strategy_payoff.
`seed`	No	Value for seed.
`rebate`	No	Value for rebate.
`tickers`	No	Comma-separated ticker symbols, e.g. 'AAPL,MSFT,GOOGL'.
`end_date`	No	End of the date range in YYYY-MM-DD format.	2026-10-02
`indicator`	Yes	Name of the specific metric to calculate, e.g. 'get_asset_turnover_ratio'. Required — omitting it returns the list of available indicators.
`quarterly`	No	Return quarterly data instead of annual when True.
`timesteps`	No	Value for timesteps.
`knock_type`	No	Value for knock_type.	out
`put_option`	No	Value for put_option.
`start_date`	No	Start of the date range in YYYY-MM-DD format.	2021-10-03

`show_columns`	No	Comma-separated names to filter the output. For historical data use the key names visible in any response record (e.g. 'Close,Volume,Return'). For financial statements use the 'metric' field values from the response (e.g. 'Revenue,Net Income,EBITDA'). Call the tool once without this parameter to see all available names, then repeat with show_columns to reduce response size and token usage.

TDQS

C2.7/5.0

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds nothing behavioral beyond annotations — no mention of data-source/auth requirements, compute cost for Monte Carlo or simulation indicators, or what happens when an indicator's params are omitted.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose sentence is front-loaded and useful, but roughly half the text is a verbatim re-listing of the 33 enum values already in the schema. That duplication inflates the description without adding selection-relevant information, which is a significant structural waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a dispatcher exposing 39 parameters and 33 indicators with an output schema present, the description never explains how the parameter set maps to individual indicators — an agent must infer from scattered schema hints which of the 39 params matter for a chosen indicator. The critical per-indicator parameter guidance is absent from the description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% across 39 parameters, so baseline is 3. The description's ticker-format note ('comma-separated values for multiple tickers') merely restates the schema's own text, and the indicator list duplicates the enum, adding no semantic depth about which params apply to which indicator.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the resource (option pricing and Greeks) and enumerates the model families it covers (Black-Scholes, binomial tree, implied volatility), so the domain is unambiguous. It does not differentiate itself from siblings like volatility, models, or econometrics, which partly overlap this territory.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only usage guidance is a prerequisite ('Requires tickers="AAPL"'), which is already documented in the schema. There is no statement of when to select this tool over volatility/models, and no guidance on choosing among the 33 registered indicators beyond listing their names.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
