Api applied controls linked models retrieve

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

The annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false. The description adds no behavioral detail beyond the basic purpose, such as permission filtering, output shape, or whether the list is static or user-scoped. With annotations present, this is a gap rather than a contradiction.

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?

The definition is a single, front-loaded sentence with no filler. Every word contributes to identifying the returned resource and its relationship to applied controls.

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?

For a zero-parameter, read-only lookup endpoint with full annotation coverage, the description gives the essential return content ('available model types that can be linked to applied controls'). It does not describe the response format, but no output schema exists and the operational context is simple enough that this is only a minor gap.

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 are no parameter semantics to explain. The baseline for zero-parameter tools is a 4, and the description correctly does not invent or misstate any parameters.

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 description states a clear verb ('Return') and a specific resource ('available model types that can be linked to applied controls'), which distinguishes it from sibling linked-models endpoints for policies or validation flows. It is slightly less than fully specific because 'model types' is not defined, but an agent can tell what the endpoint is for.

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 guidance on when to use this tool, when not to, or which alternative sibling to choose. The description only states what is returned, leaving the agent to infer that it is a discovery call for linkable model types.

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