get_podcasts_by_id_checknew

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

The description says 'download new episodes', which implies a server-side state change, while the annotations declare readOnlyHint=true. This is a direct contradiction. It also fails to disclose authentication requirements, background behavior, or whether downloads can be limited or interrupted.

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. The endpoint line and argument list are useful and concise. Minor redundancy exists between the tool name and the GET path, but it does not waste significant space.

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?

Despite having an output schema and annotations, the description leaves critical behavioral ambiguity: it describes a mutating download action while annotated as read-only, and gives no usage context. For a tool with side-effect implications, this is incomplete and potentially misleading.

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 adds meaning for 'limit' by explaining it as the maximum number of episodes to download, which is helpful. However, 'id' is only described as a path parameter, leaving its semantic role as podcast id implicit via the endpoint path rather than explicit.

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 action ('Check and download new episodes') and a clear resource (episodes for a podcast, addressed by id). The endpoint path also reinforces that it operates on a specific podcast. However, it does not explicitly distinguish itself from related siblings like get_podcasts_by_id_downloads or create_podcasts_by_id_download_episodes.

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 related podcast endpoints. The description implies it is for checking/downloading new episodes, but it does not mention alternatives, prerequisites, or conditions.

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