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

The annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is mostly covered. The description adds one useful fact that the annotations do not: the link stops opening forever, so the action is irreversible for third parties. It says nothing about required permissions, error behavior for unknown link_id, or what is returned.

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 front-loaded sentence with zero filler. It pairs the action with its consequence immediately, so nothing needs trimming.

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?

It is a destructive single-parameter tool with no output schema, and the annotations carry the safety signals. Still missing is how to obtain link_id, what success looks like, and what happens on an unknown or already-revoked id, so it is adequate but has clear gaps.

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?

The single parameter link_id has 0% schema description coverage, so the description needs to compensate and it gives no meaning at all: it does not say where link_id comes from (list_share_links, create_share_link) or what form it takes. This leaves the only parameter undocumented in both the schema and the description.

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 (revoke) and resource (public share link), which lets an agent distinguish it from the siblings create_share_link and list_share_links. It stops short of naming a sibling explicitly, so it is clear but not fully differentiated.

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 gives no when-to-use guidance, no prerequisites, and no alternative path such as using list_share_links to find the link_id. It does not say what to do if the link is already revoked or invalid, and the only implied guidance is the permanence note.

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