Update Product Category

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

Annotations indicate mutation and idempotency. Description adds that it returns the updated category object and lists error handling for 404, providing behavioral context beyond annotations.

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 brief and well-structured with sections for args, returns, and error handling, containing no superfluous information.

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?

For a simple update tool with 5 parameters and no output schema, the description covers purpose, parameters, return, and error handling adequately. It could mention additional constraints but is generally complete.

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?

With schema coverage at 40%, the description lists all parameters (id required, name/description/parent optional, response_format with default), compensating for missing schema descriptions and clarifying usage.

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 explicitly states 'Update fields on an existing product category', using a specific verb and resource, and distinguishes it from sibling tools like create and delete.

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?

It is clear the tool is for updating an existing category, with implicit differentiation from create/delete siblings. Error handling guidance for non-existent IDs is provided, but no explicit when-to-use vs alternatives is stated.

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