vast42_create_icon

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

There are no annotations, so the description must disclose behavior. It only states 'Create', implying a mutation, but provides no information about side effects, required parent objects, return values, or permissions. This is minimal disclosure about the operation's behavior.

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, focused sentence with no wasted words. It is front-loaded and readable, though it sacrifices informative content for brevity.

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 create tool with 3 parameters and no output schema, the description is under-specified. It fails to explain what a VAST 4.2 icon is, whether it is tied to an ad or companion, or the implications of creating one. The schema covers parameter formats but not the broader operational context.

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 provides complete descriptions for all three parameters (name, width, height), so the description adds no additional parameter semantics. The baseline of 3 is appropriate since the schema covers all details.

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 ('Create') and resource ('VAST 4.2 icon'), clearly identifying the operation. It is distinguishable from sibling tools like vast42_update_icon and vast42_delete_icon, though it lacks additional scope details such as the icon's role within VAST.

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 like vast42_update_icon or vast42_create_icon_click_fallback_image. There are no stated prerequisites, context for icon creation, or exclusions.

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