updateProduct

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

No annotations are provided, and the description only says 'Update an existing product's details.' It fails to disclose side effects (e.g., whether old values are overwritten, if it's destructive, authentication requirements, or approval workflow hints from the __userContext parameter).

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 extremely concise at one sentence, with no wasted words. However, it could be slightly expanded to add context without becoming 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?

With 8 parameters including nested objects and no output schema, the description is too minimal. It does not mention return values, validation constraints, or how the __userContext approval workflow affects operation, which is critical for a mutation tool in this context.

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 100%, so the baseline is 3. The main description adds no additional meaning beyond the schema's parameter descriptions, which are clear but not enriched by the tool's description itself.

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 'Update an existing product's details' clearly states the verb 'update' and the resource 'product'. However, it does not distinguish this tool from siblings like updateCustomer or updateContact, which have similar update patterns.

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 on when to use this tool versus alternatives (e.g., createProduct for new products), prerequisites, or when not to use it. The agent is left without context for appropriate invocation.

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