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

With no annotations, the description carries the full behavioral burden, and it does disclose one real consequence: queued deliveries are dropped. However, it omits whether the removal is permanent/irreversible, what permissions are needed, and what happens if webhook_id does not exist — significant gaps 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?

One sentence, front-loaded with the action and resource, with the side effect compactly bracketed. Nothing is wasted and nothing is buried.

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 one-parameter tool with no output schema and no annotations, the description covers purpose and the key delivery-dropping side effect. It is still thin on irreversibility, auth requirements, and the identifier's expected form, which an agent would need before calling a destructive tool.

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 0% for the single parameter, and the description never mentions webhook_id or its format (ID vs URL). The parameter name is largely self-explanatory, but the description makes no attempt to compensate for the undocumented schema, so it falls below the 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?

The description gives a specific verb and resource — 'Remove a webhook endpoint' — which clearly separates it from list_webhooks, get_webhook, create_webhook and test_webhook in the sibling set. It stops short of explicitly naming a sibling to route away from, so it lands at 4 rather than 5.

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?

Usage is only implied: an agent can infer this is the teardown counterpart to create_webhook. There is no explicit when-to-use guidance, no mention of alternatives such as disabling a webhook instead of deleting it, and no prerequisites stated.

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