Revert to Snapshot

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

The description warns that the operation discards any changes since the snapshot, adding behavioral context beyond the destructiveHint=true annotation. It also states the return value is a confirmation message.

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 compact, with a clear purpose sentence, a warning, and a structured argument list. The Args and Returns sections are slightly redundant with the schema but remain useful.

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?

With a destructive operation, the description adequately warns and covers the two required parameters. It does not mention the optional vm_password, but schema provides that, and the return behavior is disclosed.

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 covers all parameters with descriptions (100% coverage). The description repeats the two required parameters but adds no new meaning and omits the optional vm_password.

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 the specific verb 'revert' with 'a VMware Fusion virtual machine to a previous snapshot', clearly distinguishing it from sibling tools like create/delete/list snapshots.

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 when to use it (to roll back a VM to a snapshot) but provides no explicit guidance on alternatives or exclusions, such as when to use fusion_reset_vm instead.

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