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

Annotations declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false, so the safety profile is defined. The description adds a little about field format ('HTML content') but doesn't cover what happens on creation, validation, or rate limits.

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, front-loaded with the action and then useful field examples. No waste, though the 'etc.' is slightly vague.

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 nested-object create tool with an output schema, the description is thin. It should indicate required fields, whether the category must exist, and basic behavioral expectations. The output schema covers returns, but the input side is under-specified.

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 100% for the single 'input' parameter, but that parameter is a blanket object with additionalProperties and no field-level documentation. The description lists some fields (name, answer, knowbaseitemcategories_id, etc.) but does not compensate for the lack of schema detail on the nested object.

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 new knowledge base article.' Clearly distinguished from glpi_update_knowbase_item, glpi_get_knowbase_item, and glpi_create_knowbase_category among the sibling tools.

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 tool versus alternatives like glpi_update_knowbase_item or glpi_create_knowbase_category. No context about required permissions or prerequisites.

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