vast42_get_placement

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

No annotations are provided, so the description is the sole source of behavioral information. It clearly implies a read operation ('Get'), but adds no details about error handling, auth requirements, or return format. It does not contradict anything, but is minimal.

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, immediately stating the action and target. No fluff or repetition; it is front-loaded with the verb and clearly 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?

For a simple get-by-id tool with a single well-documented parameter and no output schema, the description covers the essential information. However, it does not mention the distinction from the regular VAST placement tools or note that it returns the full placement object, so it is not fully comprehensive.

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 fully documents the single 'id' parameter with description 'VAST 4.2 placement ID', giving 100% coverage. The description adds no additional parameter semantics beyond the schema, which meets the baseline for high 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 uses a specific verb 'Get' with a clear resource 'VAST 4.2 placement' and scope 'single', distinguishing it from list tools and the non-4.2 vast_get_placement sibling. It clearly states exactly what the tool does.

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 implies usage for retrieving a single placement by ID, but it does not explicitly mention when to use it over alternatives like vast_get_placement or list tools. No exclusions or alternative tool references are provided, so guidance is only implicit.

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