justwatch_title_offers

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

No annotations are provided, so the description bears full burden. It mentions the tool returns 'normalized offers' and accepts country codes, but does not disclose rate limits, authentication, or further behavioral traits like pagination or error handling. It is adequate for a straightforward read operation.

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 sentence that is efficient and front-loaded with the main action. However, it could be slightly more concise by reducing redundancy (e.g., 'across one to five comma-separated country codes' could be shortened).

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?

Given no output schema, the description should clarify what constitutes 'normalized offers' and possibly list response fields. It also omits any mention of error cases or limitations. Overall, it is adequate but not exhaustive.

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%, so the baseline is 3. The description reinforces the ID format and country count limit, but adds minimal new meaning beyond the schema descriptions. It does not elaborate on the language parameter.

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 tool retrieves offers for a JustWatch title by its raw ID, with country filtering. It includes the key verb 'Get' and specifies the resource 'title offers'. It effectively distinguishes from siblings like justwatch_search and justwatch_title by focusing on offers.

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 description implicitly guides usage: use when you have a raw JustWatch ID and need offers across specific countries. It does not explicitly exclude other scenarios or name alternatives, but the context is clear.

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