webhooks_get

Read-onlyIdempotent

Fetch a webhook by its ID using bot authentication to inspect its configuration and metadata, excluding the token.

Instructions

Purpose: Get a webhook by id (bot-authed lookup).

When to use:

Inspect a webhook you discovered via webhooks_list_channel or webhooks_list_guild.

Asymmetry: This bot-auth path strips token from the response - the token is only re-issued by webhooks_create and webhooks_get_with_token. Use webhooks_get_with_token when you already hold the token and want the freshest record.

Returns: Webhook fields without token. name remains raw creator-controlled data; untrusted_name provides a separately fenced copy.

A4.7/5.0

Behavior5/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds valuable behavioral context beyond annotations: it discloses that the bot-auth path strips token from the response, that token is only re-issued by webhooks_create and webhooks_get_with_token, and that name remains raw creator-controlled data while untrusted_name is a separately fenced copy. This is exactly the kind of non-obvious behavior an agent needs to know.

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?

The description is well-structured with clear labeled sections (Purpose, When to use, Asymmetry, Returns). Every sentence earns its place: the purpose is front-loaded, the usage guidance is explicit, and the asymmetry warning is critical for correct tool selection. No filler or repetition.

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

Completeness5/5

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

For a single-parameter read tool with a rich output schema and comprehensive annotations, the description is complete. It covers what the tool does, when to use it, the critical token-stripping behavior, and the untrusted_name distinction. Nothing an agent needs to call it correctly is missing.

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%, so the schema already documents the single webhook_id parameter. The description adds context about what the lookup returns and the auth path, but it doesn't add new meaning about the parameter itself beyond what the schema provides. Baseline 3 is appropriate when the schema does the heavy lifting.

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

Purpose5/5

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

The description states a specific verb ('Get'), a specific resource ('a webhook by id'), and the auth context ('bot-authed lookup'). It also distinguishes itself from the sibling webhooks_get_with_token by explicitly naming the asymmetry, so an agent can tell them apart without opening schemas.

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

Usage Guidelines5/5

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

The 'When to use' section explicitly says to use this tool when inspecting a webhook discovered via webhooks_list_channel or webhooks_list_guild, and explicitly directs agents to webhooks_get_with_token when they already hold the token and want the freshest record. This is clear when/when-not guidance with named alternatives.

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