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 category via a subdirectory, implying a write operation, but doesn't disclose behavioral traits such as permissions needed, whether duplicates are allowed, error handling, or side effects. The description is minimal and lacks critical context for safe invocation.

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 extremely concise and front-loaded in a single sentence, with no wasted words. It efficiently conveys the core purpose without unnecessary details, making it easy to parse quickly.

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 (a write operation with no annotations), the description is incomplete. It lacks details on behavior, parameters, and usage context. However, an output schema exists, so return values needn't be explained. The description provides basic purpose but misses key elements for a mutation tool.

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 semantics beyond the input schema, which has 0% description coverage. It doesn't explain what 'category_name' represents, its format, constraints, or examples. With one parameter and no schema descriptions, the baseline is 3 as the description doesn't compensate for the coverage gap but doesn't mislead either.

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 a new category') and the resource ('inside Notes'), and specifies the implementation method ('by creating a subdirectory'). It distinguishes from siblings like 'edit_category' or 'delete_category' by focusing on creation. However, it doesn't explicitly contrast with 'ensure_notes_folder_exists' which might be related to folder setup.

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 explicit guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., whether the Notes folder must exist), exclusions, or comparisons to siblings like 'edit_category' for updates or 'list_categories' for viewing. Usage is implied but not detailed.

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