get_user_choice

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

With no annotations, the description carries full burden but adds minimal behavioral info beyond stating it opens a dialog. It does not disclose blocking behavior, return value, or timeout effects.

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 a single under-specified sentence. For a tool with five parameters and no other documentation, it fails to provide necessary detail, making it not appropriately sized.

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 complexity (5 params, 3 required, no output schema, no annotations), the description is woefully incomplete. It does not cover parameter semantics, return values, or usage 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?

Schema description coverage is 0% and the description adds no explanation of the five parameters (title, prompt, choices, allow_multiple, default_values). The agent gets no help understanding parameter roles.

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 verb (open), resource (browser-based choice dialog), and purpose (for the user). It distinguishes from siblings like get_user_input and show_confirmation_dialog, which serve different interaction patterns.

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 implies usage when the user needs to make a choice from predefined options, but provides no explicit guidance on when not to use or alternatives. No scenarios or exclusions are mentioned.

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