Permanently delete a webhook endpoint. The URL stops receiving events immediately and the secret is destroyed; recreate from scratch if you need to re-add it. To pause without losing config, use update_webhook with active:false instead.
| Name | Required | Description | Default |
|---|---|---|---|
| org_slug | Yes | Org slug | |
| webhook_id | Yes | Webhook id (from list_webhooks) |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses permanent and immediate effects: URL stops receiving events immediately, secret is destroyed, and recreation is required. This is rich behavioral context about side effects and irreversibility.
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 concise sentences: first states the action, second details immediate effects, third offers the alternative. Front-loaded and every sentence earns its place with no redundancy.
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 delete operation with two well-documented parameters and no output schema, the description covers purpose, effects, irreversibility, and an alternative. It is sufficiently complete for an agent to invoke correctly.
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?
Input schema covers both parameters with simple descriptions (org_slug, webhook_id from list_webhooks). The tool description adds no extra parameter semantics. With 100% schema coverage, baseline is 3, and the description does not elevate it.
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 opens with a specific verb and resource: 'Permanently delete a webhook endpoint.' It also distinguishes from siblings by explicitly contrasting with update_webhook and noting the need to recreate from scratch after deletion.
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 provides explicit when-to-use guidance: use this for permanent deletion. It gives a clear alternative for pausing: 'use update_webhook with active:false instead.' This directly addresses the choice between siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
