Get an episode's soundbites

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

The annotations already declare readonly, idempotent, and non-destructive behavior. The description adds useful context beyond those: the data comes straight from the episode record, there is no extra fetch, and the tags are optional and uncommon. No contradiction with annotations exists.

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 front-loads the core definition, then adds a rationale and source context. The three sentences are mostly purposeful, though the 'cheapest possible answer' phrasing is slightly embellished. Overall it is concise and well-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 simple one-parameter read tool with strong annotations and full schema coverage, the description is complete enough: it explains what the data is, why it matters, where it comes from, and its rarity. Without an output schema, a bit more exact structure would help, but the payload is adequately hinted.

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?

There is only one parameter, episode_id, and the schema describes it fully as a Podcast Index episode id. The description adds no additional parameter-level meaning, but with 100% schema description coverage the baseline of 3 is appropriate.

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 identifies the resource as an episode's publisher-marked soundbites with start time and duration. The title plus first sentence make the purpose obvious. However, it does not explicitly distinguish this from the sibling get_recent_soundbites, so it lacks full sibling differentiation.

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?

It gives concrete use cases: the cheapest highlight answer and a ready-made list for promotional clips. It also says it comes straight from the episode record with no extra fetch, which helps an agent decide when this is a cheap option. It does not explicitly state when not to use it or name an alternative tool.

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