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

Annotations already state that this is a non-read-only, non-destructive, non-idempotent operation. The description adds relevant approval context, noting that MCP approval requirements are configurable and business workflow approvals always apply, but it does not describe validation behavior or side effects beyond approvals.

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?

It is short and front-loads the core create action. The phrase 'using the same business service as the screen' is vague, but the description is otherwise 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?

For a create tool with a nested input object, zero schema descriptions, and no explanation of the data fields, the description is too sparse. Output schema coverage helps with return values, but the input side remains under-explained.

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 the description does not explain the nested data fields at all. Required name, optional version, isDefault, and description are left entirely to the bare schema property names.

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 names a specific verb and resource: creating a checklist_template. It is distinguishable from siblings like update_checklist_template or create_checklist_template_item by the resource name, though it does not explicitly differentiate itself from them.

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?

It does not say when to use this tool versus alternatives such as create_checklist_template_item or apply_checklist_template. The approval note is contextual but does not provide usage guidance or exclusions.

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