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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Delete' implies a destructive, irreversible mutation, but the description doesn't mention permissions required, confirmation steps, side effects (e.g., stopping notifications), or error handling. This is inadequate for a destructive operation with zero annotation coverage.

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, efficient sentence with zero wasted words. It's front-loaded with the core action ('Delete a webhook'), making it immediately scannable and appropriate for a simple tool. Every word earns its place without 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?

Given this is a destructive mutation tool with no annotations and no output schema, the description is incomplete. It lacks critical context like what happens post-deletion, return values, error cases, or system-specific behaviors. For a tool that permanently removes resources, this minimal description poses risks 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 100%, so the schema fully documents the single parameter 'webhookId'. The description adds no additional meaning about the parameter (e.g., where to find the ID, format constraints, or examples). This meets the baseline of 3 since the schema does the heavy lifting, but no value is added beyond 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 clearly states the verb ('Delete') and resource ('a webhook'), making the purpose immediately understandable. It distinguishes from siblings like 'create_webhook' and 'update_webhook' by specifying the deletion action. However, it doesn't specify what type of webhook or system context, which prevents a perfect score.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing webhook ID), when not to use it, or how it relates to siblings like 'list_webhooks' for finding IDs or 'create_webhook' for replacement. This leaves the agent with minimal contextual direction.

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