File Is Mount Point

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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it delivers almost nothing. It does not say the operation is read-only/side-effect free, does not mention authentication or session/profile requirements despite host/port/scheme/profile parameters implying a remote NAS session, and gives no failure-mode context.

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 short sentence that is front-loaded and free of padding. It is appropriately sized for a boolean check, though it is arguably under-specified rather than genuinely concise.

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?

An output schema exists, so the description need not explain the return value. However, with zero annotations and no behavioral detail, the definition leaves the agent guessing about read-only status and session/auth expectations for what is otherwise a simple query tool.

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 all five parameters (host, path, port, scheme, profile) are already documented in the schema, establishing the baseline of 3. The description adds no additional meaning about the path format or how session parameters interact.

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 precise verb+resource: check whether a given path is a mount point. It is unambiguous and clearly distinct in function from file_property or storage_mount, but it never names a sibling or explicitly contrasts itself with related tools like file_property or storage_overview.

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 when-to-use or when-not-to-use guidance, no prerequisites, and no pointer to alternatives. The agent must infer the usage context entirely from the name and the sibling list.

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