create_category

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

No annotations are provided, so the description carries the full burden. It does disclose a genuine behavioral rule — the nesting constraint that categories may only be parented by categories — but says nothing about permissions, name uniqueness, error behavior, or whether the parent must already exist.

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 short sentences, zero waste, and the definition of the resource is front-loaded ahead of the constraint. Nothing is padded or repeated.

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 create tool with an output schema, the description covers what is created and the nesting rule. It omits defaults behavior (parent defaulting to root), whether titles must be unique, and what happens on an invalid parent — gaps that matter for correct invocation.

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 coverage is 67%, with color ("#RRGGBB") and parent ("parent category id or name; 'root' = top level") documented in the schema but title left bare. The description reinforces the parent semantics via the nesting rule, but adds no syntax or format detail beyond the schema, so baseline 3 is appropriate.

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?

Specific verb+resource ("Create a category") with a clarifying gloss ("a folder in the Master List") that defines the domain concept. It does not, however, differentiate itself from siblings like create_label or create_project, leaving the agent to infer the distinction.

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?

There is no explicit when-to-use guidance and no mention of alternatives among the many create_* siblings. The one constraint given ("Categories can only live under categories") is a structural rule, not usage direction for choosing this tool over another.

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