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

No annotations are provided, so the description carries full burden. It discloses that deletion stops redirecting and requires a specific scope. However, it does not clarify whether deletion is irreversible, what happens to associated analytics, or any side effects. More detail would improve transparency.

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 two sentences long, each contributing essential information: the action and the required scope. It is front-loaded and efficient with no wasted words.

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 simple tool with one parameter, the description is acceptable but could be more complete. It does not mention return behavior (e.g., success/failure) or provide context relative to the many sibling tools. It leaves the user to infer the effect.

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?

The schema has one parameter 'id' with no description (0% coverage). The description does not explain what 'id' represents (e.g., the link's unique identifier). It adds no meaning beyond the schema structure.

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 clearly states 'Delete a short link (it stops redirecting).' It specifies the verb 'Delete' and the resource 'short link', and the parenthetical clarifies the effect. This distinguishes it from sibling tools like create_link or update_link.

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 mentions the required scope 'links:write' but provides no guidance on when to use this tool versus alternatives like set_link_enabled or update_link. No exclusions or context for selection are given.

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