get_podcasts_by_id_downloads

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

Annotations already establish readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds the endpoint path and resource scope but does not disclose any additional behavioral details such as pagination, response format, or authorization requirements.

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 core purpose. The endpoint and argument lines are somewhat redundant with the tool name and schema, but the overall size is appropriate and easy to scan.

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 read endpoint, the description is minimally adequate, especially with an output schema and read-only annotations present. However, it lacks parameter semantics and usage context, so an agent receives only the bare mechanics of the request.

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 explaining the parameter. It only says 'id: Path parameter', which adds minimal meaning beyond the schema's bare string type. The endpoint path implies it is a podcast ID, but the description itself does not explicitly state that.

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 verb and resource: 'Get episode downloads' for a specific podcast endpoint. The endpoint path further specifies the resource. However, it does little to differentiate from related siblings like get_libraries_by_id_episode_downloads or get_items_by_id_download.

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 given about when to use this tool versus alternatives. The description simply states what the endpoint returns, with no mention of use cases, exclusions, or comparisons to similar download-related tools.

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