mmex_categories_create

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

No annotations are provided, so the description must disclose behavioral traits. It fails to mention side effects of creation (e.g., whether duplicates are allowed, permissions needed, or if the operation is reversible). The description only states that it creates a category, which is insufficient for a mutation tool without annotations.

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 concise with a short sentence followed by a bullet-like list of parameters. It is front-loaded and every sentence adds value. Minor verbosity due to the Args block, but still 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 has 4 parameters and no annotations, the description covers the basic usage. However, it omits what the tool returns (e.g., the created category object or an ID). The output schema exists but is not described, leaving the agent uncertain about the output format.

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 schema has 0% description coverage for parameters, but the description compensates by explaining each parameter's purpose: 'name' is the category name, 'parent_id' is optional for root categories, 'db_path' and 'db_key' have fallbacks to environment variables. This adds meaningful context beyond the 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?

The description clearly states 'Create a new category in the MMEX database.' The verb 'Create' and resource 'category' are specific and differentiate it from sibling tools like mmex_categories_list, mmex_categories_update, and mmex_categories_delete.

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?

While there is no explicit when-to-use or when-not-to-use guidance, the name and description make it obvious that this tool is for creating categories, contrasting with sibling tools that handle other operations. The context is clear enough for an agent to decide.

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