create_categories

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

No annotations provided, so description must carry burden. It discloses mutation (create) and return format (items, counts, errors), but omits side effects like partial success behavior, idempotency, or prerequisites. Adequate but minimal.

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?

Three crisp sentences: tool action, interface versatility, and return format. No redundancy, front-loaded, and every sentence adds value.

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 two-parameter create tool without output schema, the description covers purpose, usage mode, and return format. However, lacks details on error handling or projectId optionality context. Nearly 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?

Schema covers 100% of parameter descriptions, so baseline is 3. Description adds context on array usage ('single-item and batch') and response structure, which enhances understanding beyond raw schema.

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?

Description clearly states verb (create), resource (work item categories), and that it handles both single and batch operations via an array. It uniquely identifies the tool's purpose among siblings like create_boards or create_tags.

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?

Mentions array-based interface for single and batch usage, implying applicable scenarios, but lacks explicit when-not-to-use or alternative comparisons. Context is sufficient but not detailed.

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