Api entities country retrieve

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

Annotations declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, but the description says the endpoint allows entities to be 'viewed or edited', implying mutation capability that the annotations deny — a boilerplate-induced contradiction that could mislead an agent. Nothing is said about what is returned (a country/value list), whether auth is needed beyond session, or pagination.

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 short sentence with no padding, which is good, but the words spent are low-information boilerplate rather than a front-loaded statement of what the call returns. Brevity here comes from under-specification, not discipline.

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?

There is no output schema and no parameter schema to lean on, so the description is the only source of information about the response — yet it says nothing about returning a list of country choices. For a reference-data lookup in a CISO Assistant API, that leaves the agent unable to predict the payload.

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 there is nothing for the description to disambiguate and the baseline of 4 applies. The description neither helps nor harms here, since the empty schema is self-explanatory.

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 'API endpoint that allows entities to be viewed or edited' restates the generic Django REST Framework resource boilerplate and never says what this endpoint actually returns. The name says 'country', but the description never mentions countries, enumerations, or reference data, so an agent cannot tell it apart from entities_list or entities_retrieve.

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?

No when-to-use guidance, no prerequisites, and no reference to the obvious alternatives (entities_list, entities_retrieve, entities_object_retrieve) among the ~40 entities_* siblings. Only an implicit 'this is a read endpoint' can be inferred from the phrasing.

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