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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the safety profile is given. The description adds that deletion is permanent and irreversible, which reinforces the risk but is largely duplicative of destructiveHint; it says nothing about permission requirements, whether the alias is freed for reuse, or what happens to associated analytics/QR data.

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, and the irreversibility warning is front-loaded immediately after the action. 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?

For a one-parameter destructive tool with full schema coverage and clear destructive annotations, the description covers the essential action and risk. The remaining gaps — auth requirements and side effects on dependent resources — are real but secondary given the annotation support.

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?

There is a single required parameter with 100% schema description coverage, including an example format ('my/old-link'), so the schema does the semantic work. The description adds no further detail about the identifier format or whether an ID is accepted in place of the shortlink path.

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 and resource ('Delete a shortlink') with a permanence qualifier, which is unambiguous. It is naturally distinguishable from siblings like delete_qr_template, remove_block, and remove_social_link because the target resource is named, though it never explicitly routes against edit_link or other alternatives.

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?

There is no when-to-use or when-not-to-use guidance; the agent is not told what to do instead if it wants to disable rather than destroy a link (e.g., edit_link). Usage is only implied by the verb 'Delete'.

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