vast_update_channel_zone_assignment

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

The description provides no behavioral context beyond the tool's name. With no annotations available, the description carries the full burden of disclosing effects, permissions, or reversibility, but it discloses none of these.

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, front-loaded sentence with exactly seven words. Every word is purposeful, and there is no wasted content.

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 the lack of annotations and output schema, the description is too sparse to be considered complete. It does not explain what fields can be updated, whether the operation is partial or full replacement, or what the response will be.

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 already covers 100% of parameters with descriptions, so the baseline is 3. The description adds no additional parameter semantics, but the schema provides sufficient meaning for id, zone, and channel.

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: 'Update a VAST channel zone assignment.' It uses a specific verb (update) and identifies the resource (VAST channel zone assignment), which distinguishes it from sibling tools that create, delete, get, or list channel zone assignments.

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. The verb 'update' implies modifying an existing assignment, but there is no explicit mention of prerequisites, what fields can be changed, or exclusions.

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