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 still adds real value beyond them: the address stops working immediately, the effect extends to everyone the owner shared it with, and the underlying server service is untouched. It does not state whether removal is recoverable or what authorization is required, which keeps it at 4.

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?

Three tight sentences: the action first, then the blast radius, then the scope boundary. Every clause carries information an agent would otherwise have to guess.

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 destructive tool with full annotation coverage and no output schema, the description supplies essentially everything needed to call it safely. The only missing piece is whether the deletion is reversible or how to restore a removed link.

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 coverage is 100% for the single `id` parameter, which already states it comes from web_link_list or web_link_create. The description reinforces the source but adds no format or syntax detail beyond the schema, so the baseline 3 applies.

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 names a specific verb ("Remove") and resource ("an internal site from the owner's Termalin cabinet") and pins the identifier to its origin (from web_link_list). An agent can distinguish this from web_link_create and web_link_list without opening any schema.

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 context is clear: use it on an id obtained from web_link_list, and it removes the link rather than the server service, which excludes a plausible misreading. There is no explicit when-not guidance or named alternative for adjacent tasks (e.g., recreating or editing a link), so it stops short of a 5.

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