create_uib_component

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

Annotations already indicate a write operation (readOnlyHint=false) and non-destructive behavior, but the description adds no additional behavioral context. The '[Scripting]' tag is vague and does not clarify side effects, permissions, or return 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 efficiently short, but the '[Scripting]' tag is unclear and slightly distracts from the core message. Despite this, it is a single sentence with no redundant phrasing.

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 description is minimal and lacks essential context: it does not explain what a macroponent is, what the tool returns, any prerequisites, or how it fits into the UI Builder workflow. With no output schema, agents have no information about the response.

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 75%, so the schema covers most parameters. The tool description adds no extra meaning beyond what the schema provides, maintaining the baseline for adequately documented parameters.

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 resource ('custom UI Builder component'), and clarifies the domain term 'macroponent'. This distinguishes it from sibling tools like create_uib_page, which targets pages rather than components.

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 versus alternatives such as update_uib_component or list_uib_components. The description only defines the tool's purpose without providing context or exclusions.

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