browser_verify_value

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

With no annotations provided, the description carries full burden. It fails to disclose whether the tool is read-only (likely), what happens on match/mismatch (e.g., throws error or returns boolean), or if it waits for elements. Minimal transparency beyond the action name.

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 short sentence but under-specifies the tool's behavior. It is too terse given the tool has 4 parameters and no output schema. Conciseness should not sacrifice completeness.

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 no output schema, no annotations, and a moderate parameter count, the description should explain return behavior and usage context. It lacks any mention of outcomes or edge cases, making it incomplete for an agent to correctly invoke.

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% with descriptions, so the description adds no extra semantics beyond what the schema already provides. It does not clarify the relationship between 'ref' and 'element' or the expected format for 'value' beyond the schema's hint.

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 states it verifies an element's value, which distinguishes it from sibling tools like verify_element_visible that check visibility. However, 'value' is ambiguous—it could refer to attribute, property, or text content. The schema provides type hints, but the description lacks specificity about what constitutes a value for each type.

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 on when to use this tool versus alternatives like verify_text_visible or browser_evaluate. It does not mention prerequisites (e.g., element must be visible) or contextual cues for selection.

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