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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only states the action and parameter meanings; it does not mention side effects like overwriting existing files, permission requirements, return values, or error behavior. This is a significant gap for a creation tool.

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 well-structured: a one-line purpose followed by a compact, readable Args list. Every line adds value, especially given the schema lacks field descriptions, and there is no fluff or redundancy.

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?

Parameter semantics are well covered, but the tool has no output schema and no annotations, so the description must also explain return values, error behavior, and whether it overwrites existing files. These are absent, leaving the agent without a complete picture of the tool's behavior.

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 input schema has no descriptions for its fields, but the tool's description adds crucial meaning: file_name is without extension, suffix is without dot and includes examples, current_dir has a default, and resource_type is restricted to FILE or UDF. This richly compensates for the schema's lack of 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's function: 'Create a text file inline (no upload required).' The verb 'Create' and resource 'text file' are specific, and the 'no upload required' phrase differentiates it from sibling tools like ds_upload_file, making the purpose unambiguous.

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 provides clear context for when to use the tool—when creating a file without uploading—but it does not explicitly state when not to use it or name alternative tools beyond the implication that upload is not needed. The guidance is implied rather than explicit.

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