create_file

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

No annotations are provided, so the description carries the full burden. It only states that it creates a file from a URL and mentions the staging/external URL distinction. It does not disclose side effects, permission requirements, idempotency, error behavior, or whether the staged upload token is consumed.

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 a single concise sentence that front-loads the core action ('Create a file') and adds a useful qualifier about the source. Every word contributes, with no 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?

Given there is no output schema, the description does not mention return values or side effects. It hints at the staging workflow but does not explain how to obtain a staged upload or what the created file contains. For a mutation with no annotations, this is a moderate gap.

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?

All 5 parameters have schema descriptions (100% coverage), so the schema already documents each field. The description adds no parameter-specific meaning beyond the source URL context already implied by the parameter names.

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 action ('Create a file') and the source ('from a URL'), and distinguishes it from sibling tools like create_staged_upload (which stages uploads, not files) and get_file/update_file/delete_file. The parenthetical 'after staged upload or external URL' adds specific scope.

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 contextual guidance: it is used after a staged upload or with an external URL. This implies the workflow and when to use it, though it does not explicitly name alternatives or exclusionary cases.

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