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

Annotations already signal destructive behavior (destructiveHint: true), and the description adds valuable context beyond that: the operation only applies to owned links and results in public access. It is consistent with the annotations and clarifies the real-world effect.

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, well-structured sentence with no filler. It front-loads the action, states the target resource, includes a precondition ('owned'), and explains the outcome ('public access').

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, no-output-schema tool with strong annotations, the description covers the essential behavior and outcome. The only minor gap is the lack of explicit routing between unprotect_link, protect_link, and revoke_link, but the core calling context is sufficiently clear.

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%, with the label parameter already described as 'Label of the link to unprotect.' The description adds context about ownership and public access but does not add new parameter-level meaning, 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 uses a specific verb ('Clear') and names the resource ('an owned link') plus the resulting state ('public access'). This clearly distinguishes it from protect_link and revoke_link, even without naming them.

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 implies when to use it: when you want to remove protection from a link you own and make it public. However, it does not explicitly mention alternatives or exclusions, such as 'use protect_link for the reverse' or contrast with revoke_link.

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