updateCategory

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

With no annotations, the description carries the burden of behavioral disclosure, but it only signals 'Update'. It does not mention side effects, auth/write permissions, the fact that null removes existing goal targets, or restrictions such as internal category groups being disallowed.

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 one-liner is front-loaded and free of fluff, but it is underspecified rather than efficiently complete for a tool with three required parameters and a complex nested payload. It does not earn its place as a meaningful description.

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?

Although an output schema exists and the input schema is rich, the description lacks the context needed to orient an agent among many category-related siblings and to understand the update's scope. Key constraints and behavioral context are left entirely to the schema.

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 adds no parameter meaning beyond the schema, and schema coverage is 67%, below the high-coverage baseline. The per-field schema descriptions are useful, but the tool description does not clarify that the 'category' object is the update payload or how partial updates behave.

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 a category' restates the tool name (updateCategory) almost verbatim and adds no differentiating details. It is clear about the basic mutation but does not distinguish the tool from siblings such as updateMonthCategory or updateCategoryGroup.

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?

There is no guidance about when to use this tool instead of createCategory, updateMonthCategory, or getCategoryById. The agent must infer selection solely from the name and schema.

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