vast42_create_interactive_creative_file

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

With no annotations provided, the description carries full behavioral burden. It only says 'Create' and does not mention side effects, required permissions, duplicate handling, or what the response contains. This is a significant gap for a mutating operation, comparable to the update_drive example.

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, direct sentence that immediately states the verb and resource. It contains zero filler words or repetition, making it exceptionally concise and easy to parse.

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?

Despite having only two parameters and a simple schema, the lack of output schema and behavioral detail leaves the description incomplete. The agent is not told what happens after creation, what the return value is, or how this file fits into the broader VAST 4.2 creative structure, which is important given the large sibling toolset.

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 100% for both parameters (`name` and `mime_type`), so the description does not need to add parameter-level detail. The description itself adds no semantic depth beyond the schema, which is acceptable given the high schema coverage.

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 creates a VAST 4.2 interactive creative file, identifying the specific resource type and distinguishing it from generic creative tools like vast42_create_creative. However, it reads as a direct expansion of the tool name and does not elaborate on the file's role.

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 vast42_update_interactive_creative_file or vast42_create_creative. There are no preconditions, context, or exclusion criteria, leaving the agent without direction for choosing between related create/update operations.

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