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

No annotations are provided, so the description carries full burden. It states the action ('wait for a navigation to complete') but lacks behavioral details such as what triggers the wait, error handling on timeout, or side effects. This is inadequate for a tool with potential blocking behavior and timeout parameters.

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, efficient sentence with no wasted words. It is front-loaded and directly states the tool's purpose, making it highly concise and well-structured.

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 tool's moderate complexity (navigation waiting with timeout), no annotations, and an output schema (implied by context), the description is minimally adequate. It covers the core action but lacks details on behavior, prerequisites, or error handling, leaving gaps for an AI agent.

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 100%, with clear descriptions for 'url' (pattern types) and 'timeout' (milliseconds). The description adds no parameter semantics beyond the schema, but the baseline is 3 since the schema adequately documents parameters.

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 ('wait for') and resource ('navigation'), making the purpose understandable. It distinguishes from siblings like browser_wait_for_selector by specifying navigation rather than DOM elements. However, it lacks specificity about what constitutes 'complete' navigation (e.g., network idle, DOM ready).

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 guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., must be called after browser_navigate), exclusions, or comparisons with siblings like browser_wait_for_selector. The description alone offers no usage context.

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