get_library_sections_by_section_id_on_deck

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method (GET) which is consistent, but it does not elaborate on return structure or any special behaviors. This is acceptable given the output schema exists, but the description adds little 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 compact: a one-line purpose, the endpoint, and a single argument description. There is no fluff, but the redundant HTTP endpoint in the description adds minimal value. Still, it is appropriately sized and structured.

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 single-parameter read-only tool with an output schema and strong annotations, the description is mostly adequate. However, it lacks any explanation of what 'On Deck' means (e.g., items in the section that are partially watched) and does not address when to choose this over similar tools. This leaves some context gaps.

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 provides only the parameter name and type (integer) with no description. The description adds a semantic explanation: 'The unique identifier of the library section', which helps the agent understand what value to pass. Given 0% schema coverage, this compensation is valuable.

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 the operation ('Get On Deck for Section') and includes the HTTP endpoint, making the resource explicit. However, it does not explicitly differentiate from sibling tools like get_library_metadata_by_id_on_deck or get_library_sections_by_section_id_unwatched, so the agent must infer the distinction from the name.

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 about when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or comparison with sibling section-level getters. The agent is left to infer from the name alone, which is insufficient given the large sibling set.

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