Update Outbound Webhook

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

Annotations only include openWorldHint: true, indicating potential side effects. The description merely states 'Update' without disclosing what happens during failure, whether it performs a partial or full replacement, or what the return value is.

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 a single, clear sentence without fluff. It could be slightly more informative but remains efficient.

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 simple update tool with a well-documented schema, the description is minimally adequate. However, it lacks explanation of webhook concepts or constraints (e.g., URL validation) that would help an agent fully understand the tool's context.

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?

All 5 parameters have descriptions in the schema, so the baseline is 3. The tool description adds no extra semantic value beyond what the schema already provides (e.g., 'Updated URL' is repeated).

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 the verb 'Update' and the resource 'existing outbound webhook configuration'. It distinguishes from creation or deletion but does not elaborate on what a webhook is or differentiate from inbound webhook tools.

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 vs alternatives like create_outbound_webhook or delete_outbound_webhook. No prerequisites mentioned beyond the required 'id' parameter.

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