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

Since no annotations are provided, the description bears full responsibility for behavioral disclosure. It only states the action and lists arguments, omitting side effects, permissions, or return behavior, which is insufficient for a mutation tool.

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?

The description is concise, with a single purpose sentence followed by a structured argument list. No word is wasted, and the information is front-loaded.

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?

The description covers the parameters adequately and benefits from the output schema, but lacks usage context and behavioral details beyond the basic creation action. It is minimally sufficient for a create operation without annotations.

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?

The description lists all six parameters with brief but meaningful explanations, clarifying coordinate units (px) and the roles of reference_widget_id and parent_id. This compensates for the 0% schema description coverage, though definitions are minimal.

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 first sentence 'Create a comment widget on a mural' precisely identifies the action (create) and resource (comment widget), distinguishing it from sibling creation tools like create_sticky_notes or create_titles. The purpose is immediately understandable.

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?

The description provides no guidance on when to use this tool versus alternatives, nor exclusions or prerequisites. It simply describes the action without context on selection.

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