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

No annotations are provided, so the description carries the full burden. It discloses that deletion affects 'all its data,' indicating a destructive operation, but doesn't mention behavioral traits like irreversibility, permissions required, rate limits, or error conditions. It adds some context but is incomplete for a mutation tool.

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 that front-loads the key action and scope. Every word earns its place, with no redundancy or unnecessary details, making it highly concise and well-structured.

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 the tool's complexity (destructive mutation with no annotations and no output schema), the description is minimally adequate. It states the purpose and scope but lacks details on behavior, error handling, or output expectations. It meets basic needs but has clear gaps for safe agent use.

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%, with the parameter 'webhook_token' fully documented in the schema. The description doesn't add any meaning beyond the schema, such as explaining token format or source. Baseline 3 is appropriate as the schema handles parameter documentation.

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 specific action ('Delete') and resource ('a webhook.site endpoint and all its data'), distinguishing it from siblings like 'delete_request' (single request) and 'delete_all_requests' (all requests for an endpoint). It precisely defines the scope of 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 implies usage context by specifying 'endpoint and all its data,' suggesting this is for permanent removal of an entire webhook. However, it lacks explicit guidance on when to use this versus alternatives like 'delete_request' or 'delete_all_requests,' or prerequisites such as needing the webhook token.

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