get_ranger_service_definition

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

With no annotations, the description must disclose behavior. It implies a read-only operation ('Get'), but does not explicitly state it is non-destructive, require no special permissions, or describe any potential side effects. It is acceptable but could be more explicit.

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 description is a single, concise sentence with no wasted words. It is front-loaded with the action and resource, making it quick to parse.

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?

Given that the tool has an output schema (which likely defines the returned structure), the description is adequately complete for a simple retrieval tool. It covers the core purpose, though it could mention that the service type parameter corresponds to a component type or list valid types.

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 schema has one parameter 'service_type' with no description or enum. The description uses 'component type' which adds minimal clarity—it does not explain what constitutes a valid component type or provide examples. Schema coverage is 0%, so the description should compensate but fails to do so meaningfully.

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 clearly states it retrieves the service definition schema (access types, resources, mask types) for a component type. The verb 'Get' and resource 'service definition schema' are specific, and the tool is distinct from siblings like get_ranger_service or get_ranger_policy.

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 guidance is provided on when to use this tool versus alternatives (e.g., get_ranger_service, search_ranger_policies). There is no context on prerequisites, common use cases, or when this tool is particularly appropriate.

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