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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the description only needs to add context — but it adds nothing. It does not say whether the deletion is permanent, what happens when the id does not exist, or what the response contains, which matters for a destructive operation. No contradiction with annotations — no annotation contradiction.

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?

A single short sentence with no waste, but it is terse to the point of under-specification rather than tightly informative. There is no front-loaded scoping or consequence information.

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 destructive delete with no output schema, the description should convey permanence, error behavior on unknown ids, and post-conditions. The annotations cover the safety profile, but the description leaves the operational consequences entirely unstated.

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 a single documented required parameter (webhook_id, uuid), so the schema carries the semantics. The description adds no format or behavioral detail about the identifier, which is the adequate baseline.

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?

"Remove a webhook" gives a clear verb and resource, so an agent can tell it deletes a webhook. It stops short of differentiating from siblings such as create_webhook, webhooks_update, webhooks_get, or test_webhook beyond the verb itself.

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?

There is no guidance on when to use this versus webhooks_update or list_webhooks, no prerequisites (e.g., ownership, existence checks), and no exclusions. The agent must infer usage from the name alone.

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