vast42_create_icon_click_fallback_image

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

With no annotations provided, the description must disclose behavioral traits but only states a generic create action. It does not mention any side effects, dependencies on an existing icon, dimension validation, or what happens on success/failure.

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 that clearly states the purpose without waste. However, it is almost too sparse, lacking additional context that could be included in a second sentence without harming conciseness.

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?

The low complexity (3 simple params, no output schema) is offset by the resource being a nested object (icon click fallback image) with likely dependencies on an icon. The description does not explain what a fallback image is or any constraints, leaving the agent without critical 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 schema already documents all three parameters (name, width, height) with descriptions, and coverage is 100%. The description adds no additional meaning beyond the schema, so the baseline score of 3 is appropriate.

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 (VAST 4.2 icon click fallback image). It distinguishes this from sibling tools like vast42_get/update/delete/list_icon_click_fallback_image and other create tools for different resource types (e.g., vast42_create_icon).

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 provides no context about when to use this tool versus alternatives, such as whether it must be associated with an existing icon or when a fallback image is required. No exclusions or conditional guidance are included.

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