create_ux_app_route

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

The description includes the '[Write]' tag, which explicitly marks this as a write operation, adding clarity beyond the annotations (readOnlyHint=false). No other behavioral traits (e.g., side effects, required permissions, error conditions) are disclosed. With annotations present, the description adds minimal value but is not contradictory.

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 extremely concise, consisting of a single sentence and a bracketed tag. Every word is functional, and the most critical information is front-loaded. No unnecessary words 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?

For a creation tool with a simple input schema and no output schema, the description covers the essential purpose and write nature. However, it lacks information about return values, validation behavior, or constraints. Given the limited complexity, it is adequate but not rich.

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 already describes all four parameters with 100% coverage. The description does not add any additional meaning or context beyond what's in the schema. Baseline score of 3 is appropriate since the schema does the heavy lifting.

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 ('register') and the resource ('new route (URL path) in a UX app'). It is specific and distinguishes this tool from siblings that create other entities (e.g., 'create_uib_page', 'create_ux_experience'). However, it could be more explicit about linking the route to a target page, which is a key aspect.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use it, or how it differs from similar create tools. The agent has to infer usage from the name and context.

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