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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety bar is partly covered. The description still earns credit by disclosing the QR code being marked deleted and the public page going dark — user-visible consequences not in the annotations. It stops short of saying whether the deletion is recoverable.

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 short sentences, front-loaded with the gating condition, then effect, then the confirmation requirement. No filler.

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 single-parameter destructive tool with rich annotations and an output schema, the description covers trigger condition, effect, blast radius and the confirmation step. Nothing an agent needs to invoke it correctly 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?

With one parameter at 100% schema coverage, the schema already documents that page_id comes from `list_link_pages` and must not be guessed. The description adds nothing about the parameter beyond what is already in the structured field, so 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 states a specific verb (delete) and resource (landing page), and adds the side effect on the associated QR code, so the agent knows exactly what is being removed. It does not explicitly distinguish itself from the similarly-named sibling delete_short_link, which is the main gap.

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?

"Use this only when the user clearly asks to delete a landing page" is an explicit gating condition, and "Confirm first" adds a required precondition. No alternative tool (e.g. delete_short_link, update_link_page) is named for adjacent needs, keeping it 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.
