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

Annotations broadly indicate this is not read-only but do not detail side effects. The description adds only that the webhook has a specified auth type, which is already reflected in the schema. It does not disclose behavior such as required permissions, URL validation, whether headers are optional, or what happens on duplicate webhook names—leaving the safety and effect profile underspecified.

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 short and front-loaded, but the first sentence 'Create Workspace Webhook' merely repeats the tool name. The second sentence provides minimal value. It is concise but primarily because it contains so little information; it does not suffer from verbosity, but it also does not use the available space to earn each sentence.

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 tool has a nested settings object with several required fields, no output schema, and no property descriptions. The description does not adequately explain the domain context, how webhook_url should be formatted, what auth types are supported, or what account refers to. For a mutation with this complexity, far more context is needed.

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%, so the description must compensate for explaining parameters. It only mentions 'authentication type', which merely restates the auth_type field. It does not explain 'account', 'name', 'webhook_url', or 'request_headers', so the agent has little understanding of what values to supply or their purpose.

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 clearly states this tool creates a new workspace webhook, using the specific resource 'webhook' and the action 'create'. It distinguishes itself from sibling tools like edit_workspace_webhook_route and delete_workspace_webhook_route by explicitly stating it creates a new webhook, though it doesn't elaborate on the 'route' aspect implied by the tool name.

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 gives no explicit guidance on when to use this tool versus alternatives. There are sibling tools for editing, listing, and deleting workspace webhook routes, but the description only says 'create a new webhook' without mentioning when creation is appropriate, any prerequisites, or why to choose this over related tools.

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