vast42_create_placement

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

With no annotations provided, the description must disclose behavioral traits. It only states 'create,' implying mutation, but omits any details about side effects, required advertisement specifics beyond the schema, return values, or authorization. This is severely inadequate 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, direct sentence with no fluff, front-loading the verb and resource. It is concise but arguably too terse for the tool's complexity, though it does not waste words.

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?

This is a complex create operation with a nested advertisement object, 6 parameters, no output schema, and no annotations. The one-sentence description does not explain what a placement is, how the nested object should be semantically structured, or what happens on creation, leaving major gaps.

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?

Schema descriptions cover 100% of parameters, including the nested advertisement object, so the baseline is 3. The description itself adds no parameter semantics, but the schema carries the burden effectively.

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 ('Create') and the specific resource ('a VAST 4.2 placement'). The VAST version differentiates it from the many sibling placement-creation tools, making its purpose unambiguous.

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 given about when to use this tool versus alternatives like vast_create_placement, create_placement, or draft_create_placement. There is no mention of prerequisites, suitable contexts, or exclusions.

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