browser_wait_for

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

The description adds context about waiting for text, which is beyond the annotations (readOnlyHint), but lacks details on polling behavior, timeout handling, or error conditions. The behavioral traits are only partially disclosed.

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, well-structured sentence that is front-loaded and contains no superfluous 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?

For a simple tool with no output schema and three optional parameters, the description covers the core functionality. However, it omits specifics like default timeout or behavior when no parameter is provided, leaving minor gaps.

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 100%, so the description adds limited extra meaning beyond restating parameter names. It does not clarify mutual exclusivity of parameters or default behavior.

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 tool waits for text appearance, disappearance, or a timeout. This distinguishes it from sibling tools like browser_click or browser_navigate, which perform different actions.

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 for waiting on page conditions, but does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or limitations.

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