get_library_sections_by_section_id_unwatched

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

The annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds no additional behavioral context such as what 'unwatched' means, whether results are paginated, or any authentication or rate-limit considerations. It simply repeats the GET endpoint, which does not go beyond what annotations and the tool name already convey.

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 short and front-loaded with the purpose. The endpoint path is slightly redundant with the tool name, but it serves as a concrete reference. The Args section is minimal and directly useful. No unnecessary fluff.

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 simple single-parameter GET endpoint with robust annotations and an output schema, the description is mostly complete. The missing usage guidance is the main gap, but the purpose and parameter semantics are clear enough for the agent to select and call the tool correctly.

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's property description coverage is 0%, so the tool description carries the burden of explaining the parameter. It does define section_id as 'the unique identifier of the library section', which is meaningful and sufficient for a single required integer parameter. It could mention where to find this ID, but the definition is clear enough for correct invocation.

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 specific action and resource: 'Get Unwatched for Section' with the exact endpoint path. The verb and resource are clear, and the endpoint path removes ambiguity about which resource is affected. However, it does not explicitly differentiate itself from similar section-based siblings like all, on_deck, or recently_added.

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 versus alternatives. With a large set of sibling tools such as get_library_sections_by_section_id_all and get_library_sections_by_section_id_on_deck, the agent is left to infer when 'unwatched' is the appropriate choice. No when-not or alternative conditions are provided.

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