compose_components

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

No annotations are provided, so the description carries full burden for behavioral transparency. It does not disclose side effects, whether the tool is destructive, permissions needed, or what happens with the composition (e.g., persistent or transient). The description is too minimal to inform safe usage.

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 one sentence, which is concise. However, it sacrifices necessary detail for brevity. It front-loads the purpose but does not earn its place with additional value beyond stating the obvious.

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 the tool's moderate complexity (2 parameters, 1 optional with enum, no output schema) and lack of annotations, the description is insufficient. It does not cover return values, behavior, or how the composition is generated. Sibling tools like 'create_form' and 'generate_component' would benefit from more 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 input schema has 2 parameters with 50% description coverage; only 'layout' has a description. The tool description adds no parameter semantics beyond the schema. For 'components', the format (array of objects with type, props, children) is not explained, leaving ambiguity about required nested properties.

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 tool's purpose as creating a composition of its-just-ui components. It uses a specific verb ('Create') and resource ('composition of multiple its-just-ui components'). However, it does not differentiate from sibling tools like 'create_form' or 'generate_component', which have overlapping functionality.

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 offers no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or scenarios where this tool is preferred over siblings like 'create_responsive_layout' or 'configure_theme'.

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