vast_create_channel_zone_assignment

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only states the intended action without mentioning idempotency, failure modes, permissions, or effects on existing assignments. This is a significant gap for a mutation 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 a single, concise sentence that efficiently communicates the core purpose without redundant wording. It is appropriately sized for a tool with only two parameters.

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?

With no annotations or output schema, the description is incomplete for a mutation tool. It does not explain assignment semantics (e.g., idempotency, duplicate handling) or differentiate from the update tool. This leaves the agent without enough context to handle edge cases confidently.

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 covers both parameters with clear descriptions ('VAST zone ID', 'VAST channel ID') at 100% coverage. The description adds no additional meaning beyond what the schema already provides, meeting the baseline for 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 action ('assign') and the resources ('VAST zone', 'VAST channel'), making the purpose obvious. However, it does not explicitly distinguish this create operation from the sibling update_channel_zone_assignment, relying on the tool name's 'create' prefix for that distinction.

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 the update or delete variants, nor does it mention any prerequisites or conditions (e.g., whether channel and zone must already exist). There is no explicit when-to-use or alternative guidance.

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