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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether it reads state, what it returns, whether it mutates anything, or what the recommendation is based on. '(ui-advisor)' is a label, not behavioral disclosure.

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?

It is short, but brevity here comes from under-specification rather than tight writing — a single fragment that conveys no actionable content. There is nothing to front-load because nothing is said.

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?

A two-parameter tool with zero annotation coverage, zero schema descriptions, and no output schema gets no compensating detail from the description. An agent has no way to invoke this correctly or interpret the result.

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?

Both parameters have 0% schema description coverage, so the description must compensate and does not. The enum values (managed/partial/full, low/medium/high) are somewhat self-explanatory, but the description never mentions them or explains how ownershipLevel and customizationLevel drive the recommendation.

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 is essentially the tool name and namespace restated, plus a parenthetical '(ui-advisor)'. That hint suggests it advises on UI mode, but there is no verb or stated outcome, so an agent cannot confidently say what it does versus siblings like ui.overrides.guide or sdk.recommend.

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 when-to-use, when-not-to-use, or alternative guidance is given. With ui.overrides.guide and sdk.recommend in the same family, the agent has no basis for choosing this tool over them.

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