Upload File (Dalux Box)

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

Annotations indicate readOnlyHint=false, but the description adds important behavioral details: handles the 3-step chunked upload flow, constraints on file area types, and write access requirement. This adds value beyond annotations, though it could mention error handling or rate limits.

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 relatively concise (four sentences) and front-loaded with the main action. No irrelevant information, but could be slightly more structured by separating use cases more clearly.

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?

The description covers the main use cases and constraints, but for a complex upload tool with 8 parameters and no output schema, it lacks information about the response format or what the agent can expect after a successful upload. This leaves a gap in 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 50%, and the description does not elaborate on individual parameters beyond the schema. However, it clarifies the use of fileId vs folderId for new vs revision uploads, which adds context. The description compensates partially but not fully for the missing schema descriptions.

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 uploads a file to Dalux Box, specifies two modes (new file into folder or new revision of existing file), and distinguishes from siblings like dalux_download_file. The verb 'Upload' and resource 'Dalux Box file area' are specific.

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?

Explicitly states when to use (uploading documents) and when not to (file areas of type published/shared). Also mentions prerequisite of write access and the need to confirm the target folder with the user. Provides clear context for usage.

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