karea_create_category

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

No annotations are provided, so the description carries full burden. It states 'return it' implying the created category is returned, but does not disclose side effects, permissions, failure modes, or validation behavior. For a create tool, more transparency about conflict handling or idempotency would be beneficial.

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?

Two sentences, no fluff, and the main action is front-loaded. Every word earns its place, and the structure is efficient.

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 the tool's simplicity (2 parameters, no output schema), the description adequately covers the basic purpose and key sibling alternative. However, it could be more complete by mentioning that the project must exist or that the name must be unique within the project.

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 baseline is 3. The description adds minimal value beyond the schema: it hints that the category is created inside a project, but does not clarify whether projectId is required or optional (schema lists it as not required). No details on parameter formats or defaults are provided.

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 action (create), the resource (category/task bucket), and the context (inside an existing project). It also distinguishes from the sibling tool karea_create_project, making the purpose unambiguous.

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 explicitly tells when not to use this tool (for creating a whole project) and suggests an alternative (karea_create_project). However, it does not provide guidance on prerequisites (e.g., the project must exist) or when to use it over other category-related siblings like karea_delete_category.

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