Uncheck page control

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

Adds behavioral details beyond annotations: idempotency (already in annotations), timeout bounding, and session isolation. Also notes that the locator can be semantic or CSS, giving insight into how the tool locates elements.

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 concise, two sentences, and front-loaded with the core action. No redundant information or fluff.

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?

Provides sufficient context for a simple action but does not elaborate on the complex locator schema, potential failure modes, or prerequisites. Given the complexity of the input schema, it could be more explanatory, but it is adequate for an experienced user.

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 0% and the description does not explain the meaning of key parameters (ref, pageId, locator, sessionId) nor the locator structure. It only indirectly hints at timeoutMs and sessionId. This falls short of compensating for the lack of parameter explanations.

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?

Description clearly states the action (uncheck a checkbox) and the resource (checkbox), with explicit mention of locator strategies (semantic or CSS) and page targeting. It distinguishes from sibling tools like browser_check.

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?

Clearly implies when to use (to uncheck a checkbox) and provides operational context (idempotent, bounded by timeout, session-isolated). However, it does not explicitly contrast with alternatives like browser_check or mention when not to use.

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