Read-onlyIdempotent

Calculate bond duration, present value, yield-to-maturity, and derivative prices by providing bond or derivative parameters directly as arguments.

Instructions

Bond and derivative valuation calculations (bond duration, present value, yield-to-maturity, derivative pricing). No tickers or countries needed — provide bond/derivative parameters (e.g. face_value, coupon_rate, maturity) directly as arguments.

Available indicators: get_derivative_price, get_duration, get_present_value, get_yield_to_maturity.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
guessNoValue for guess.
modelNoValue for model.black
end_dateNoEnd of the date range in YYYY-MM-DD format.2026-06-27
notionalNoValue for notional.
countriesNoComma-separated country names, e.g. 'United States,Germany,Japan'.
frequencyNoValue for frequency.
indicatorYesName of the specific metric to calculate, e.g. 'get_asset_turnover_ratio'. Required — omitting it returns the list of available indicators.
par_valueNoValue for par_value.
quarterlyNoReturn quarterly data instead of annual when True.
toleranceNoValue for tolerance.
bond_priceNoClean price of the bond per 100 face value.
start_dateNoStart of the date range in YYYY-MM-DD format.2021-06-28
volatilityNoValue for volatility.
coupon_rateNoAnnual coupon rate as a decimal, e.g. 0.05 for 5 %.
is_receiverNoValue for is_receiver.
strike_rateNoOption strike price.
forward_rateNoValue for forward_rate.
show_columnsNoComma-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.
duration_typeNoValue for duration_type.modified
include_payoffNoValue for include_payoff.
max_iterationsNoValue for max_iterations.
risk_free_rateNoValue for risk_free_rate.
show_input_infoNoValue for show_input_info.
years_to_maturityNoYears remaining until the bond matures.
yield_to_maturityNoValue for yield_to_maturity.

Behavior4/5

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

Annotations already indicate readOnlyHint, idempotentHint, and openWorldHint. The description adds that omitting the indicator returns the list of available indicators, which is useful context. No contradictions with annotations.

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

Conciseness4/5

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

Description is three sentences, concise, and front-loaded with the main purpose. It could be slightly more structured, but it is effective and not verbose.

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

Completeness3/5

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

Given the complexity (25 parameters, many with generic descriptions) and presence of an output schema, the description is adequate but could be improved by explaining when to use each indicator or how parameters interact.

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%, so baseline is 3. However, many parameter descriptions are generic ('Value for guess.'), and the tool description does not add additional meaning beyond what is in the schema.

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

Purpose5/5

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

The description clearly states 'Bond and derivative valuation calculations' and lists specific indicators (get_duration, get_present_value, etc.), making the tool's purpose unambiguous and distinct from sibling tools like market_data or valuation.

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

Usage Guidelines4/5

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

The description notes that no tickers or countries are needed and that parameters should be provided directly. It lists available indicators, but does not explicitly contrast with siblings or detail when to use this tool over alternatives.

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