update_webhook

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

The description provides no behavioral information whatsoever. Since no annotations exist, it must carry the full burden of disclosure, but it fails to mention idempotency, mutations, permissions, response, or any effects beyond 'update'.

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 very concise (one sentence) and front-loaded. However, it is under-specified; while brevity is valued, it sacrifices essential information. It could include a brief summary of updateable fields.

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 is severely incomplete given the tool's complexity (2 required params, nested body object, no annotations). It does not explain the webhook resource, update behavior, result format (despite an output schema), or error conditions, leaving large gaps for an AI agent.

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. It does not describe any parameter meanings. The schema itself provides descriptions for the nested body properties, but the description adds nothing, leaving the agent to rely solely on the schema.

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 'Update a webhook endpoint,' which is a specific verb+resource. It distinguishes from sibling tools like create_webhook and delete_webhook. However, it lacks details on what aspects can be updated (e.g., url, description, events), which would improve clarity.

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?

No guidance on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions. The description is a bare statement of purpose without any usage direction.

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