get_libraries_by_id_podcast_titles

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds only the HTTP method and path, with no additional behavioral context such as response shape or special cases. It does not contradict 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 very short and front-loads the core action and endpoint. Every line is compact, though the 'Args' section is minimal and could be integrated more usefully. It is appropriately concise but not overly padded.

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?

The tool is a simple read endpoint with one parameter and an output schema, so it does not need to explain return values. However, the description lacks context about what 'podcast-titles' means, how the library id relates to the resource, or any caveats. It is minimally viable but leaves semantic 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?

Schema description coverage is 0%, so the description must compensate for the undocumented 'id' parameter. It only says 'id: Path parameter,' which adds that it is a path parameter, but fails to clarify that id represents a library ID or specify expected format. This is insufficient given the low schema coverage.

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 verb and resource: 'Get libraries podcast-titles' with the endpoint 'GET /api/libraries/{id}/podcast-titles'. This distinguishes it from sibling library endpoints such as get_libraries_by_id_authors or get_libraries_by_id_series, though the phrase 'podcast-titles' is awkward and could be clearer.

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. The endpoint suggests it retrieves podcast titles for a library, but there are no explicit conditions, exclusions, or references to sibling tools.

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