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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the description needn't restate safety. But it adds nothing beyond them: no note on duplicate-slug handling, required permissions, or whether the taxonomy is immediately visible.

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?

A single front-loaded sentence with no waste, but it is thin to the point of under-specification rather than efficient. There is room for a short clause on prerequisites or slug behavior.

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 non-idempotent mutation tool with 0% schema coverage and no output schema, the description does far too little. An agent must infer parameter semantics and failure modes from nothing.

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 0% and three of four properties have empty descriptions. The description mentions no parameters at all, leaving name, slug, and description semantics (format, constraints, whether slug is auto-derived) entirely undocumented; only the kind enum self-documents.

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?

States a specific verb (create) and resource (category or tag) and disambiguates the two entity kinds, matching the title. It distinguishes itself from list_taxonomy by verb alone, though it doesn't explicitly reference it.

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 on when to use this versus list_taxonomy or how it relates to content creation (e.g., that a taxonomy must exist before assigning it). No prerequisites, no exclusions, no mention of behavior when the slug already exists.

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