operations_stat

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

No annotations are provided, so the description must fully disclose behavioral traits. It states the tool returns metadata but does not describe the specific fields (e.g., name, size, modtime), whether it is read-only, potential side effects, or performance characteristics. The reference to `rclone lsjson` is helpful but insufficient for an agent without domain knowledge.

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 sentence that efficiently conveys the core functionality. It is well-structured and front-loaded with the action ('Stat an object').

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 the lack of an output schema and annotations, the description is somewhat incomplete. It does not explain the format of the returned metadata or behavior for non-existent items. For a simple stat operation, it may be adequate, but more detail would improve completeness.

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%, meaning all 5 parameters are documented in the schema. The tool description adds minimal value beyond the schema, only referencing `rclone lsjson`. Therefore, a baseline score of 3 is appropriate.

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 clearly states the tool's purpose: 'Stat an object — Returns metadata for a single file or directory.' This distinguishes it from sibling tools like operations_list, which lists multiple items, and operations_size, which returns total size. The reference to `rclone lsjson` provides additional context.

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 for a single item ('single file or directory') but does not explicitly specify when to use this tool versus alternatives like operations_list or operations_check. There is no mention of prerequisites or conditions for use.

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