Get document example

get_document_example
Read-onlyIdempotent

Inspect a fixed synthetic request and expected result before integrating or paying. Select service from the enum; no caller document is accepted, processed or stored. Returns service and details containing that service's example. Free; no wallet authorization. Use get_document_service_status for current readiness, prices and retention instead.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds valuable behavioral context beyond annotations: it states that no caller document is accepted, processed, or stored, and that the tool is free. This clarifies side-effect-free operation and cost implications, going beyond the annotation flags.

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?

Four sentences with clear front-loading of purpose and usage. No redundant filler; every sentence adds information. The alternative tool is mentioned at the end without cluttering the core description.

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?

For a single-parameter tool with a complete schema, output schema, and comprehensive annotations, the description covers purpose, usage, behavioral constraints, and alternatives. Nothing essential is missing for correct invocation.

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 coverage is 100%, and the schema already describes each enum value in detail. The description's 'Select service from the enum' adds little beyond what the schema provides, but it does reinforce that examples do not process caller documents. This meets the baseline for high schema coverage.

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 a specific action ('Inspect a fixed synthetic request and expected result') and resource (document examples for a service). It distinguishes itself from siblings by explicitly naming get_document_service_status as the alternative for status/prices/retention.

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

Usage Guidelines5/5

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

Explicitly states when to use (before integrating or paying) and provides a direct exclusion ('Use get_document_service_status for current readiness, prices and retention instead'). The when-not condition is unambiguous.

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