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

The destructiveHint=true annotation already flags this as a destructive operation, but the description adds meaningful context beyond it: the removal is recoverable and re-creation yields a new id. It still omits any permission/auth requirements or effects on in-flight submissions.

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?

Three terse sentences, front-loaded with the core action, then recovery information, then the underlying API endpoint. No filler and nothing buried.

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 single-parameter destructive operation with full schema coverage, complete annotations, and no output schema, the description supplies everything an agent needs: what it does, that it is reversible, and how to undo it.

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% and the schema already documents webhookId as the id returned by fillout_create_webhook. The description adds no additional syntax, format, or constraint detail beyond the schema, so 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?

States a specific verb+resource ('Stop a webhook from receiving submissions') that is unambiguous and clearly distinct from sibling tools like fillout_create_webhook or fillout_list_submissions. An agent can identify the operation without opening the schema.

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?

Explains the recovery path by naming the alternative sibling fillout_create_webhook and noting the id changes, which tells the agent what to do next. It does not state explicit exclusions or when-not-to-use conditions, so it falls short of full routing guidance.

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