Api privacy data contractors country retrieve

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

The description claims the endpoint allows data contractors to be "viewed or edited," while annotations declare readOnlyHint=true and destructiveHint=false. This states write capability the tool does not have, and it adds nothing about the actual behavioural profile (no auth notes, no indication that this is a fixed choice/enumeration lookup with openWorldHint=true).

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

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

It is a single front-loaded sentence with no padding, so structurally it is fine. But the sentence is unedited boilerplate that carries no tool-specific information, so brevity comes from being generic rather than from being economical.

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

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

With zero parameters, no output schema, and annotations already covering safety, the description needed to say what the endpoint actually returns (country choices for contractor records) and when to call it. Instead it misidentifies the resource and the allowed operation, leaving the agent less informed than the tool name alone.

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

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

The tool takes zero parameters, so the schema cannot be enriched and the baseline of 4 applies. Note, however, that the absence of any path/query parameter is itself a hint that this is a value-lookup endpoint, which the description fails to convey.

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

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

The sentence is a generic DRF template that restates the tool name ("data contractors ... viewed or edited") and drops the distinguishing token "country". An agent cannot tell from this whether the tool returns contractor records, a country value, or a list of country choices, nor how it differs from privacy_data_contractors_retrieve or the other *_country_retrieve siblings.

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

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

There is no when-to-use guidance, no prerequisites, and no mention of alternatives despite many near-identical siblings (privacy_data_contractors_retrieve, privacy_data_contractors_list, entities_country_retrieve, privacy_data_transfers_country_retrieve). The agent must infer everything from the tool name.

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