list_library_sections_all

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint false. The description adds the provider-scope restriction, which is useful, but does not disclose any additional behavior such as pagination or provider semantics that would go beyond the annotations.

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 meaningful sentence followed by the endpoint; every token adds information and there is no filler. It is front-loaded with the action and constraint.

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 list operation with an output schema and read-only annotations, the description is nearly sufficient. The main gap is leaving the phrase 'main Media Provider' undefined and not contrasting with sibling list tools, but the endpoint and name cover most of the needed context.

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 input schema has zero parameters, so there is no parameter burden for the description to carry. The 'main Media Provider Only' note partially explains the endpoint's scoping, while schema coverage makes missing parameter docs a non-issue.

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 action ('Get') and resource ('library sections'), and adds a scope constraint ('main Media Provider Only') plus the exact endpoint. It does not explicitly name a sibling to distinguish itself from, but the endpoint and 'all' in the name make its role understandable.

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?

'main Media Provider Only' gives implied usage context and an exclusion, but there is no explicit guidance about when to use this over list_library_sections or get_library_sections_by_section_id_all. The routing decision is left to inference from naming conventions.

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