Auto UI from parameters

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

The description discloses concrete mutation behavior: 'appends them as custom parameters on comp_path (default source_path), and optionally binds each control back to the source parameter.' It also reveals inference behavior ('infers sliders/toggles/text fields'). Annotations only state non-readonly/non-destructive, so the description adds meaningful behavioral context beyond them, though it doesn't cover edge cases like existing controls or overwriting.

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?

Three sentences, all dense and front-loaded. The first sentence states the core action, the second explains mechanics, and the third gives usage context. No filler or redundancy.

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?

Given 7 parameters and no output schema, the description covers the core workflow (read, infer, append, bind) and primary use case. It doesn't specify return values or behavior with pre-existing controls, but within the open-world context it is sufficiently complete for an agent to decide when and how to invoke it.

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 coverage is 100%, so the baseline is 3. The description adds context for source_path (read from), comp_path (defaults to source_path), and bind (optional binding), but does not elaborate on page, exclude, parameters, or max_controls, which are already fully documented in the schema.

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 starts with a specific verb and resource: 'Generate a performable control panel from an existing node/COMP's primitive parameters.' It clearly distinguishes this tool from siblings like create_control_panel by emphasizing automatic inference from existing parameters and optional binding.

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 final sentence gives explicit usage context: 'Use when a generated component has useful parameters but no playable UI yet.' This provides clear guidance but does not state explicit exclusions or name alternatives, making it a clear context without exhaustive exclusions.

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