vast_get_placement

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 'Get details' which is the obvious action, but does not disclose any behavioral traits such as read-only safety, required permissions, error responses, or return format. It adds no value beyond the literal meaning.

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 ('Get details of a specific VAST placement') that is fully front-loaded and contains no wasted words. It is appropriately sized for a simple get-by-ID tool.

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 simple signature (one required ID parameter, no output schema, no annotations), the description is minimally sufficient. However, it does not explain what 'details' will be returned, nor does it clarify which VAST API version (VAST vs VAST42) this applies to among the many sibling get tools, leaving some ambiguity.

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 describes the only parameter 'id' with 'VAST placement ID' at 100% coverage. The description does not add any additional meaning to the parameter. Baseline of 3 is appropriate since schema fully covers it.

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's function using a specific verb ('Get') and resource ('details of a specific VAST placement'). It distinguishes from sibling list/create/update/delete tools, and 'specific' indicates a single entity by ID. The purpose is immediately apparent.

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 gives no explicit guidance on when to use this tool versus alternatives like vast_list_placements, vast_create_placement, or other get variants (get_placement, vast42_get_placement). The word 'specific' implies a need for an ID, but no exclusions or alternative recommendations are provided.

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