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 the call is read-only, what it returns, whether it requires an existing app scaffold, or how recommendations are derived. The single word 'ui-advisor' is not a 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 this is under-specification rather than conciseness. The only content beyond the name is a vague parenthetical label that adds no actionable information.

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?

With no annotations, no output schema, and 0% parameter documentation, the description should carry the entire burden of explaining the tool. It does not: an agent has no idea what inputs mean, what a recommendation looks like, or how to act on 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?

Two parameters (ownershipLevel, customizationLevel) exist with enums but 0% schema description coverage, and the description adds no meaning for either. The agent must guess what 'managed'/'partial'/'full' ownership or low/medium/high customization imply for 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 a restatement of the tool name with a parenthetical tag '(ui-advisor)'. It implies the tool recommends a UI mode for MediaSFU React Native, but never states this as a verb+resource action in prose, nor distinguishes it from 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?

There is no when-to-use guidance, no preconditions, and no mention of alternatives. An agent cannot tell from this text when ui.mode.recommend should be selected over android::ui.mode.recommend or shared::ui.overrides.guide.

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