update-product-preferences

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

Annotations are absent, so the description carries the full burden. It only says preferences are updated, without disclosing partial-update behavior, the meaning of null values, environment-list merge semantics, or any permission implications.

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?

A single, front-loaded sentence with no filler. It states the action, resource, and key parameter efficiently while remaining easy to parse.

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 endpoint has nested objects, nullable fields, and environment-specific arrays, but the description does not explain update semantics (e.g., whether omitted fields are preserved, what null clears). With no output schema or annotations, the description is too sparse for an agent to invoke confidently.

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 description references productId but adds no meaning beyond the schema. The requestBody is not described at the top level, though its nested properties are well documented; the term 'preferences' provides a mild semantic label but the schema does most of the work.

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 uses a specific verb ('updates') and a specific resource ('preferences of a Product') identified by `productId`. This clearly distinguishes it from sibling tools like update-product and get-product-preferences.

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 about when to use this tool versus reading preferences via get-product-preferences or updating other product fields via update-product. No prerequisites or exclusions are mentioned.

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