generate_license_plate_frame

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the interactive 3D stage, hosted browser stage link behavior, automatic mesh decimation, and free-tier quota, but it does not explain whether the generated frame is persisted, how the result is returned, or what authentication/account state is required beyond a passing mention of being signed in.

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 purpose is front-loaded, but the description repeats the inline 3D stage behavior twice and includes promotional upgrade links and tier language that do not help an agent invoke the tool. The duplicated stage explanation and marketing copy make it less concise than it should be.

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 20-parameter generation tool with no output schema and no annotations. The description explains the stage and quota but omits what the call actually returns, whether a design or mesh is saved, and how the generated frame relates to later print/export steps, leaving important gaps for correct invocation and follow-up.

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 description coverage is 100%, so the schema already covers all 20 parameters at the baseline level, even though most descriptions are only defaults. The tool description adds no parameter-specific meaning such as how top_text, size, material, or US versus EU plate dimensions should be chosen, so it does not exceed the baseline.

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 first sentence states a specific verb and resource: generate a license plate frame for a US or EU plate. It clearly distinguishes this from general make-loop tools like design_session and compile_scad, but it does not explicitly differentiate itself from other product generators such as generate_nameplate or generate_wall_plaque.

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 gives some context by saying design_session is not installed here and compile_scad is the make-preview-iterate loop, but it does not state when an agent should choose this specialized generator over the many sibling product generators. Usage is implied by the tool name rather than explicitly guided.

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