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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile for this read. The description adds only the mildly useful signal that the record is 'crawled' (i.e., a snapshot rather than live data), but says nothing about freshness, coverage, or what happens on a missing id.

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?

Two short sentences, front-loaded with the action and followed by the alternative. The dataset enum wording is slightly redundant against the tool name, but nothing else wastes 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?

An output schema exists, so return-value detail is not required here; the agent gets purpose, the single required parameter, and a sibling route. Missing only an explicit pointer to the search/facets siblings for discovery workflows.

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 coverage is 100% and the single id parameter is documented there with a concrete example ('173001861'). The description's 'by id' adds no format or constraint detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb+resource ('Returns one crawled Apple Podcasts show record by id') and scopes it to the dataset enum value 'apple-podcasts-shows', which separates it from the live apple_podcasts_show sibling. It does not distinguish itself from the same-family listing tool datasets_apple_podcasts_shows_search, so it falls short of a 5.

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?

Explicitly names the alternative 'apple_podcasts_show' for retrieving show details, giving the agent a clear routing rule between the dataset snapshot and the live source. It omits the corresponding guidance for datasets_apple_podcasts_shows_search, so no explicit when-not condition is stated.

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