get_shows_favorited_by_period

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the description need not repeat safety properties. It adds useful behavioral details such as the GET endpoint, pagination defaults/clamping, and watchnow value semantics, but does not describe sort order or response behavior beyond 'most favorited'.

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 Args list is structured and free of overt fluff, and the summary line is concise. However, many entries merely restate 'Query parameter,' adding length without semantic value, and the watchnow block is verbose.

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 output schema covers return shape and annotations cover safety/idempotency, while the description adds pagination and filter details. The missing period value semantics and lack of sibling differentiation are real gaps, but the tool is callable for straightforward uses with the information provided.

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 carry parameter meaning. It gives real detail for watchnow, limit, and ignore_* flags, but the required 'period' parameter is only described as 'Path parameter' with no accepted values, and date/genre/rating/country formats are left entirely to inference from their names. This is insufficient for 17 parameters.

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 opening sentence 'Get the most favorited shows' states a specific verb and resource, and the endpoint path clarifies that results are scoped by a period. It does not explicitly distinguish this from closely related sibling period tools like collected/played/streaming/watched, 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?

The purpose implies when to use the tool—when favorited shows for a period are needed—and the parameter list suggests filtering use cases. However, there are no explicit exclusions or guidance about when to prefer an alternative sibling tool, so usage guidance remains only implied.

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