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

Annotations already declare this is a non-readOnly, non-destructive, closed-world insert. The description adds no behavioral context beyond that — no note about default placement, no auth or permission requirements, and no indication of what the mutation returns or how insertion ordering behaves. For a write tool it does not pull its weight.

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 efficient sentence with the key noun phrase front-loaded and no filler. It is well-formed, though at one clause it offers no structure for scannability.

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?

Given seven parameters, a mutation-style operation with no output schema, and a dense sibling set, the description is minimal but the rich schema carries most of the load. It is adequate to invoke correctly, but an agent gets no help on selection or on insertion-order semantics that the schema only partially hints at.

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 100%, so all seven parameters (including the non-obvious `after`, `position`, and `isHidden`) are documented in the schema itself. The description contributes no additional parameter meaning, so the baseline 3 applies.

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 (Insert) and a specific resource (signature pad question for handwritten signatures), which clearly distinguishes it from the other ~30 editor_insert*Question siblings. It stops short of explicitly contrasting with alternatives like editor_insertTextQuestion, but the resource is unambiguous.

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?

There is no guidance on when to use this tool versus other question types, nor any mention of prerequisites (form must exist, region must be editable) or when-not-to-use. The agent must infer that this is chosen whenever a signature field is wanted.

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