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 never says whether this is a partial or full update, what happens to fields omitted (or passed as null), whether the change is reversible, or what permissions/scope are required for the mutation.

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 under-specified rather than concise — brevity comes at the cost of all operational detail an agent would need.

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 7-parameter unannotated mutation tool with no output schema and no documented parameters, one sentence is far from sufficient. Nothing tells the agent how to invoke it correctly or what it returns.

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?

Seven parameters with 0% schema description coverage and the description mentions none of them. The agent gets no explanation of name, slug, icon, description, order_index, or the required bot_id/category_id beyond their bare titles.

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 (Update) and resource (Help Center category), and 'an existing' clarifies it modifies rather than creates. It does not distinguish itself from siblings like update_help_center_article, create_help_center_category, or delete_help_center_category beyond the resource noun.

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 when-to-use guidance, no prerequisites, no mention of when to prefer create/delete/update-article siblings. The word 'existing' hints that the category must already exist, but nothing else is stated.

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