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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description adds nothing on top of that — no mention of permanence, whether the proxy can be recovered, or any cascade effects — so it contributes no behavioral context.

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 one-sentence description is essentially a restatement of the tool title 'Remove a proxy' with no added information. It is short, but that brevity reflects under-specification rather than economical writing.

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 single-parameter delete tool with annotations covering destructiveness and idempotency and no output schema, the minimum needed to call it is present. It is still thin: nothing tells the agent whether deletion is permanent or what happens to dependent resources.

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% for the single 'id' parameter, so the schema already documents it fully. The description adds no meaning beyond the schema, which is the expected baseline for full coverage.

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?

States a specific verb and resource ('Remove a proxy'), which is unambiguous on its own. However it offers no differentiation from the many sibling delete_* tools (delete_label, delete_site, delete_traffic_source), so an agent must rely on the name alone to route correctly.

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 update_proxy, restore_site, or the other delete_* siblings, and no prerequisites or cautions are given. The description supplies nothing beyond the bare action.

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