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

No annotations are provided, so the description carries the full burden of behavioral disclosure — and it discloses nothing. It does not say whether this returns guidance text, requires a prior mode selection, or has any side effects, so an agent cannot predict the outcome of calling it.

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 that brevity is under-specification rather than conciseness — the string is a namespace header, not a front-loaded description of behavior. There is no structure to evaluate because there is no content.

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 two-parameter tool with a constrained enum, no annotations, and no output schema, the description is entirely inadequate. An agent has no basis to decide when to call this rather than a sibling, or how to populate its arguments.

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 coverage is only 50%: the 'focus' enum (branding, layout, cards, controls, headless-shell, native-bridge) has no description at all, and 'mode' only gets the circular gloss 'SDK-supported UI ownership mode.' The description text adds zero information about either parameter, so it fails to compensate for the coverage gap.

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 a near-verbatim restatement of the tool name and namespace path ('MediaSFU Angular :: ui.overrides.guide (ui-overrides)'), with no verb or statement of what the tool actually does. It gives no hint that this is guidance for UI overrides, nor how it differs from the sibling angular::ui.mode.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 prerequisites, and no routing to alternatives. The sibling list contains an obvious near-neighbour (angular::ui.mode.recommend) and several overlapping guide tools, yet the description does nothing to disambiguate them.

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