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 the tool creates a new category, implying a write/mutation operation, but doesn't disclose behavioral traits such as required permissions, whether the operation is idempotent, what happens on duplicate names, or the response format. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 a single, efficient sentence that front-loads the purpose ('Create a new category') and adds clarifying context ('collection for organizing products'). There is zero waste, and every word earns its place, making it highly concise and well-structured.

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 complexity as a mutation with no annotations and no output schema, the description is incomplete. It lacks details on behavioral aspects (e.g., permissions, idempotency), response format, or error handling. For a create operation in a system with many sibling tools, more context is needed to guide effective use.

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%, with clear descriptions for 'name' and 'description' parameters. The description adds no additional parameter semantics beyond what the schema provides (e.g., it doesn't explain naming conventions or description usage). Baseline is 3 since the schema does the heavy lifting, but the description doesn't compensate with extra insights.

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') and resource ('new category/collection'), specifying it's for organizing products. It distinguishes from siblings like 'update_category' or 'delete_category' by indicating creation rather than modification or deletion. However, it doesn't explicitly differentiate from 'list_categories' or 'get_category' beyond the verb, which keeps it from a perfect score.

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. It doesn't mention prerequisites (e.g., permissions), when not to use it (e.g., if a category already exists), or direct alternatives like 'update_category' for modifications. The description is purely functional without contextual usage advice.

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