get_library_sections_by_section_id_recently_added

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the endpoint and parameter identity, but provides no extra behavioral context such as pagination, ordering, or response-level caveats.

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 compact and front-loaded with the core purpose, then provides the endpoint and the single parameter explanation. There is no filler or redundant restatement.

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 the low complexity, one parameter, rich annotations, and an existing output schema, the description provides the essential information an agent needs to invoke the tool. The main missing piece is guidance on when to use it versus its numerous siblings.

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?

Schema description coverage is 0%, so the description must compensate. It does explain that section_id is 'the unique identifier of the library section,' which adds meaning beyond the schema's bare 'Section Id' title and suffices for a single simple parameter.

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?

'Get Recently Added for Section' is a specific verb+resource statement, further reinforced by the explicit endpoint. It clearly identifies what the tool does, though it does not differentiate it from sibling tools like list_library_recently_added or get_library_sections_by_section_id_newest.

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?

The description states only that the tool gets recently added items for a section. It gives no guidance on when to choose this tool over the many related sibling tools, nor does it mention exclusions or alternative approaches.

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