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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered structurally. The description adds meaningful behavioral context beyond that: the removal is permanent and the URL stops working immediately, which tells the agent the consequence is user-visible and abrupt. It stops short of stating whether any recovery path exists or what authorization is required.

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?

Two short sentences with zero filler. The permanence constraint is front-loaded, followed by the immediate effect, which is exactly the information an agent needs before invoking a destructive operation.

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 schema coverage and annotations carrying the safety hints, the description is nearly sufficient: it conveys permanence and immediate URL breakage. A brief note on irreversibility or authorization would close the remaining gap, but nothing critical is missing.

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 single 'id' parameter documented as 'The link's slug or id.' The description adds no additional meaning about the identifier format or accepted values, so the baseline of 3 is appropriate.

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 ('Permanently remove a published link'), which is clear enough to distinguish it from siblings like delete_note or delete_project. However, the tool name says 'delete_page' while the title and description say 'link', leaving ambiguity about whether a page and a link are the same object, and no sibling is named explicitly.

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 the use case (removing a published link) but gives no explicit when-to-use guidance, no prerequisites, and no alternatives such as restore_revision or revoke_recipient. The agent must infer that this is the correct tool from the wording alone.

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