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

With no annotations, the description carries full burden. It indicates a read-only operation via 'Get' and adds the behavior of returning only 'recent' episodes, which is useful. However, it does not disclose response format, ordering, pagination, or error behavior, leaving gaps in transparency.

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 a single, direct sentence with no filler. It front-loads the core action and scope, making it immediately understandable and appropriately sized.

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 has no output schema and no annotations, so the description should explain the return structure and any prerequisite steps. It covers the core purpose but does not mention that the podcast ID comes from search_podcasts (though the schema notes it) or what fields the episodes contain. Given the simplicity, it is minimally viable but not complete.

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 input schema has 100% parameter description coverage, so the baseline is 3. The description briefly reiterates the podcast ID but adds no extra syntax, constraints, or relationships beyond what the schema already provides. No compensation is needed.

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 action 'Get', the resource 'recent episodes', and the scope 'for a specific podcast by podcast ID'. It distinguishes from sibling tools like get_episode_details which focus on a single episode, while this tool returns multiple episodes for a podcast.

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 like get_podcast_latest or get_episode_details. The description states what it does but does not mention exclusions, prerequisites, or when a different tool would be more appropriate.

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