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

No annotations are supplied, so the description carries the full behavioral burden, and for a state-changing restore operation it discloses almost nothing. It does not say whether the current site state is preserved or overwritten, whether the operation is reversible, what permissions are needed, or what happens if the version does not exist.

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?

A single front-loaded sentence with no wasted wording. It is efficient, though its brevity contributes to the missing detail noted elsewhere rather than being a flaw of structure.

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 destructive restore tool with no annotations, no output schema, and two fully undocumented parameters, the definition is too thin. It should at minimum state the prerequisite of listing versions and the effect on the current site state.

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%, so the description must explain both parameters, yet it only vaguely gestures at 'version' via 'saved versions' and never clarifies what 'slug' identifies. Format, accepted value range, and where the version identifier comes from are all undocumented.

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 combination (return the site to one of the saved versions), so the action is unambiguous. It is distinguishable from vebhost_versions (which lists versions) and vebhost_publish, though it does not name any sibling explicitly.

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 alternatives, no prerequisite stated (such as first obtaining a version via vebhost_versions), and no warning about the conditions under which a rollback should or should not be performed. The phrase 'saved versions' hints at a prerequisite but never says it.

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