Delete Webhook

delete_webhook
DestructiveIdempotent

Delete a webhook subscription (stop receiving its deliveries). Irreversible — the signing secret is invalidated.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

    "arguments": {
      "webhookId": "<webhookId>"
    },
    "name": "delete_webhook"
  }
}

TDQS

A3.8/5.0
Behavior4/5

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

Annotations already flag destructiveHint=true and idempotentHint=true; the description adds meaningful context beyond that by naming the irreversibility and the specific casualty (the signing secret is invalidated). It doesn't say whether delivery history is retained or what error occurs for a missing ID, so not a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, zero filler, with the destructive consequence front-loaded right after the purpose statement.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter destructive mutation whose safety profile is already covered by annotations, this is nearly sufficient. Minor gaps remain around post-deletion state (delivery history, secret invalidation side effects) but nothing blocks correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the commandId retry semantics are documented in the schema itself. The description adds nothing about either parameter, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource (delete a webhook subscription) and clarifies the effect with 'stop receiving its deliveries'. Siblings like create_webhook/update_webhook/verify_webhook are self-evidently different, but it never names them, so it falls just short of full differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The parenthetical implies when you'd want this (to stop deliveries), but there is no explicit when-to-use guidance, no mention of alternatives such as updating/pausing a webhook, and no note on what happens for an unknown webhookId.

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