upload_protect_file

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

With no annotations provided, the description carries the full transparency burden, and it does so well: it warns that uploads go to NVR storage, notes that overwriting system files may not be reversible, and discloses that file_type is not validated on read-back. These are non-obvious behavioral traits that materially affect safe invocation.

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 warning is front-loaded, each parameter earns its place with concrete operational detail, and there is no filler. The structure makes the high-risk nature immediately visible before parameter details.

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 destructive, annotation-free write operation, the description covers the essential context: the effect, the irreversibility risk, exact parameter semantics, known valid categories, and path behavior. The output schema exists, so not restating return values is acceptable.

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%, so the description must fully explain the parameters, and it does. It defines host formats, enumerates the known file_type categories, clarifies the path-selection behavior, gives a filename example, and specifies base64 encoding for content.

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 names a specific action ('Upload'), a specific resource ('Protect device asset file'), and the destination ('NVR storage'), which clearly differentiates it from the large sibling set. The WARNING further pins the operational intent by emphasizing that this writes to NVR storage.

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 conveys when to use the tool by explaining that it uploads asset files and by giving known file_type categories, but it does not explicitly contrast it with alternatives such as list_protect_files or other Protect operations. Guidance is implied rather than stated as explicit when/when-not conditions.

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