set_scale_width_height

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

This description carries the full burden of behavioral disclosure since no annotations are provided, but it discloses nothing about side effects, mutations, prerequisites, or whether it operates on the current selection. The phrase 'expanded operation' is vague and adds no concrete behavioral information.

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 short, but it is under-specified rather than concise. It does not earn its place because it adds no information beyond the tool name. The result is a non-informative fragment.

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 Premiere Pro operation with no annotations, no output schema, and a nominal parameter count of 0, this description is completely inadequate. It omits essential context about the operation's purpose, prerequisites, and effects, leaving the agent unable to invoke the tool correctly.

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?

Although the schema has zero parameters, the description hints at 'scale width height' but fails to explain how these values are supplied (e.g., via UI selection, default values, or missing parameters). With 0 params, the description should confirm the tool is self-contained or clarify that it acts on existing state, but it does neither.

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 "Premiere Pro expanded operation: set scale width height" is a tautology that merely restates the tool name without explaining what the tool actually does. It does not clarify whether it sets scale properties on a clip, sequence, or something else, nor does it distinguish this from sibling tools like set_clip_scale or set_scale_to_frame_size.

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?

There is no guidance on when to use this tool or which alternatives exist. No mention of required selection or context, and no comparison to related tools such as set_uniform_scale. The agent is left without any basis to decide when this tool is appropriate.

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