Rename Guest File

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

No annotations are provided, so the description carries the behavioral burden. It clearly communicates the core mutation, but does not disclose overwrite behavior, failure conditions, or prerequisites. The old-path-replaced-by-new-path semantics are reasonably inferable, but side effects are not fully specified.

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 concise sentence with an active verb and clear object. It avoids repeating schema property names or adding filler, so every word earns its place.

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 low-complexity tool with complete parameter schemas, the definition is minimally usable. However, with no annotations and no output schema, it leaves out behavioral details and alternative-selection guidance, so it is adequate rather than fully self-sufficient.

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 100%, so the parameters are already well documented by the schema. The description does not add extra semantic detail beyond the rename/move action, which is acceptable given the schema's completeness.

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 concrete operation—'Rename or move a file inside the guest VM'—and clearly identifies both the resource and scope. This distinguishes it from sibling file operations like copy, read, delete, and listing tools.

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?

No guidance is given about when to use this tool versus alternatives such as file_copy_to_guest, file_copy_from_guest, or guest_delete_file. Prerequisites like guest tools or path validity are also not mentioned.

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