dbfs_put

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

The description states 'upload', which implies a write operation, consistent with the annotation readOnlyHint=false. However, it does not disclose additional behavioral details like whether overwrite is allowed by default, whether parent directories are created, or what the response returns. The annotations already cover the safety profile, so the description adds minimal value.

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 very short at one sentence, which is concise but lacks structure. It is not front-loaded with key information like required permissions or behavior for overwrite and encoding. It sacrifices completeness for brevity.

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 tool has 4 parameters, an output schema, and the complexity of file uploads (encoding, overwrite), the description is incomplete. It does not explain the overwrite parameter's impact, the encoding options, or what happens when the path does not exist. More details are needed for an agent to use it correctly.

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?

The description does not refer to any parameters beyond the generic 'contents' and 'path'. Schema description coverage is 75%, meaning most parameters are already documented in the schema, but the description adds no additional meaning or context for parameter usage.

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 contents to a DBFS path, distinguishing it from sibling tools like dbfs_get (download) and dbfs_delete (delete). However, it does not specify that it can create or overwrite files, which is implied but not explicit.

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, such as dbfs_get for reading or dbfs_mkdirs for creating directories. There is no mention of prerequisites or exclusions.

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