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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly states that the tool deletes the reservation, deployed site, and all document DB data, which is critical destructive information. It does not mention irreversibility explicitly, but deletion implies it. Overall, it transparently discloses the major side effects.

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 a single, efficient sentence that front-loads the primary action ('Release your reserved subdomain') and then enumerates the consequences. Every word earns its place; there is no redundancy or padding.

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?

Given that there is no output schema and no parameters, the description covers the essential context: what is released and what is deleted. It does not describe return values or success indicators, but for a destructive operation, the key information is the scope of deletion, which is provided. Minor omission: it does not explicitly state that the action is irreversible, but that is implied by 'deletes.'

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 input schema has zero properties, so there are no parameter details to explain. The baseline for zero parameters is 4, and the description does not need to compensate for any missing parameter info. The description adds no parameter semantics because none exist.

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 uses a specific verb ('Release') and clearly identifies the resource ('your reserved subdomain'). It goes beyond a simple definition by enumerating the specific effects: deleting the reservation, any deployed site, and all document DB data. This distinguishes it from sibling tools like reserve_subdomain and clear_site.

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 usage: release a subdomain you previously reserved. It lists the actions taken, helping infer the consequences. However, it does not explicitly state when to use this tool versus similar alternatives like clear_site, nor does it provide exclusions or prerequisites. Guidance is implicit rather than explicit.

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