delete_link

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is carried structurally. The description reinforces irreversibility ("cannot be undone"), which is useful confirmation, but adds nothing about what happens to associated stats/QR data or whether the delete is soft then purged.

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, zero filler, with the permanence warning placed immediately after the action. Nothing to trim and nothing buried.

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 no output schema, the safety side is adequately covered by annotations plus the warning. The remaining gap is the missing identification of what `id` is and the absence of routing to the non-destructive sibling, both of which an agent needs before calling.

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 0% and the description says nothing about the lone `id` parameter — whether it expects an internal link ID, a slug, or a full short URL. With one undocumented required parameter, the description needed to compensate and does not.

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 delete a short link") plus the permanence qualifier, so an agent immediately knows what the tool does. It does not distinguish itself from the sibling disable_link, which is the obvious non-destructive alternative, so it falls short of 5.

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 guidance on when to use this versus disable_link or update_link, and no exclusions or prerequisites stated. The only hint is the word "Permanently," which implicitly contrasts with disabling, but the agent must infer that.

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