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

The annotations already signal destructive and non-idempotent behavior. The description adds meaningful context beyond the annotations by stating the concrete effect on the link: protection is cleared and it becomes public. It also implies an ownership requirement, which is useful 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?

A single, tightly worded sentence that front-loads the verb and object, states the outcome, and includes the ownership qualifier. There is no redundant or filler content.

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 simple one-parameter tool with no output schema, the description covers the action, the precondition (owned link), and the result (public access). It could be slightly more explicit about reversibility or behavior when the link is not protected, but overall it is sufficient for correct invocation.

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 input schema covers the only parameter, label, with a clear description. The tool description does not add parameter-level detail, but schema coverage is 100%, so the baseline of 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 clearly identifies the action (clear protection), the object (an owned link), and the outcome (returning it to public access). It distinguishes itself from siblings like protect_link and revoke_link by specifying the result, so an agent can tell them apart without opening other definitions.

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 phrase 'on an owned link' sets the relevant context: the tool applies to links the user owns, and 'returning it to public access' implies the link is currently protected. It does not explicitly mention alternatives such as revoke_link, but the usage context is clear enough for correct selection.

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