upload_file

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'Upload' but does not detail whether the file is automatically printed (despite a 'print' parameter), overwriting behavior, or error handling. The agent cannot infer essential side effects.

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 extremely short (one sentence), efficient in length but lacking structure. It fails to present key details upfront, such as required parameters or side effects.

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 8 parameters and no output schema, the description is insufficient. It does not explain the return value, possible errors, or the workflow after upload. The file path parameter could benefit from format examples.

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 coverage is 100%, so the baseline is 3. The description adds no extra meaning beyond the schema's parameter descriptions. It does not explain the interplay between parameters (e.g., when 'bambu_model' is required).

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 it uploads a local file to the printer, but does not differentiate from sibling tools like upload_gcode, which also upload files. The verb 'Upload' and resource 'local file to the Bambu Lab printer' are specific, but without distinguishing file types or 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?

No guidance is provided on when to use this tool versus alternatives (e.g., upload_gcode, print_3mf). There is no mention of prerequisites, or when NOT to use it, leaving the agent to infer based on file type.

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