vast42_create_media_file

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only indicates a creation action but does not disclose side effects, required parent entities, return behavior, or error conditions. An agent would not know what happens on success or what constraints apply, making this minimal transparency.

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 sentence, which is concise and front-loaded with the action. However, it is under-specified, lacking essential context that would make the sentence fully useful. It is not a tautology but is too sparse to be considered well-structured.

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?

The tool has 5 parameters and no output schema or annotations, so the description must compensate for the lack of context. It does not explain how the media file relates to other VAST entities, what the expected response is, or any operational constraints. The description is inadequate for an agent to use the tool correctly in a realistic workflow.

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 schema has 100% description coverage for all five parameters, so the baseline is 3. The description does not add any parameter semantics beyond what the schema already provides, but the schema descriptions are clear enough for the agent to understand the parameter meanings.

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 'Create a VAST 4.2 media file' clearly states a specific action (create) and resource (VAST 4.2 media file), which distinguishes it from sibling update/delete/list operations. However, it is minimal and does not elaborate on what constitutes a media file, leaving some ambiguity for an agent unfamiliar with the domain.

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 no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., an existing linear ad), context, or when alternative tools like vast42_create_linear or vast42_create_mezzanine might be more appropriate. There is no usage context provided.

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