Compare reviewed answers across places

answer_compare

Read-onlyIdempotent

Return the reviewed answers to one question for several objects side by side (for example the minimum investment of several programmes, or a tax rate in several countries), each with its official quotations. Objects not covered are listed in missing — never guessed. Aliases count once; at least two distinct recognised objects are required. coverage describes answer availability for this request only, not completeness of law or personal applicability. Display missing objects and the coverage note when presenting partial results.

Input Schema

Name	Required	Description

TDQS

A4.4/5.0

Behavior5/5

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

Beyond the readOnly and idempotent annotations, the description discloses important behavioral traits: uncovered objects are listed in missing and never guessed, aliases count once, and coverage describes answer availability only rather than legal completeness or personal applicability. It also instructs the agent to display missing objects and the coverage note when presenting partial results.

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

Conciseness5/5

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

The description is front-loaded with the core comparison purpose, then adds only relevant constraints and presentation guidance. Every sentence contributes to correct invocation or result handling, with no redundant restatement of the schema.

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

Completeness5/5

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

Given the rich annotations, full schema coverage, and presence of an output schema, the description is complete enough for correct use. It covers purpose, minimum object requirements, missing-data behavior, alias handling, and coverage interpretation without needing to explain return fields.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds useful meaning for the objects parameter: aliases count once and at least two distinct recognised objects are required. It also clarifies that the question is answered for multiple objects side by side, though locale and question format are already documented in the schema.

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 states a specific verb and resource: return reviewed answers to one question for several objects side by side, with examples such as minimum investment and tax rate. It makes the multi-object comparison scope clear, but it does not explicitly distinguish itself from sibling tools like answer_lookup or answer_objects.

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?

It gives clear usage conditions: at least two distinct recognised objects are required, aliases count once, and missing objects must be shown rather than guessed. However, it does not explicitly name alternatives such as answer_lookup for single-object lookups or answer_objects for object discovery.

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