rename_path

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

Annotations already indicate the operation is not read-only and is not idempotent, but the description adds no behavioral detail beyond the rename/move action. It does not disclose what happens if the destination exists, whether move across filesystems is supported, or whether permissions are affected.

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, front-loaded sentence with no filler. While it is concise and easy to parse, it sacrifices meaningful detail that could have been added without much bloat.

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 state-changing filesystem operation with two undocumented parameters and no output schema, this description is too thin. It omits edge-case behavior, destination collision semantics, path interpretation, and effects of the operation, leaving an agent uncertain about correct invocation.

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%, and the description does not explain what from_path and to mean beyond the obvious rename/move context. An agent cannot tell whether 'to' must be a full path, a filename, or whether directories are accepted; the parameter names and titles do most of the work.

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: 'Rename or move a file or directory.' This makes the tool's core operation clear and distinguishes it from siblings like delete_path or open_path, though it does not explicitly name or differentiate against those alternatives.

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 tool versus alternatives such as copy, delete, or open operations. No contextual conditions, prerequisites, or exclusions are mentioned, so an agent must infer usage entirely from the tool name.

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