browser_clear_permissions

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

With no annotations, the description carries the full burden of behavioral transparency. It fails to disclose what permissions are cleared, whether it clears all permissions or a subset, whether it affects the current page or the entire browser session, or any side effects. The word 'clear' implies mutation, but no specifics are given.

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 extremely short, but this is under-specification rather than effective conciseness. It consists of just two Chinese characters that add no value beyond the tool name. It is not appropriately sized because it omits essential information that would help an agent understand the tool's purpose.

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 lack of annotations and output schema, the description should fully explain the tool's behavior. 'Clear permissions' is a vague phrase that leaves the agent unsure about scope, side effects, and relationship to other permission-related tools. This is completely inadequate for a tool that could have significant impact.

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?

The input schema has zero parameters, so the baseline is 4. The description adds no parameter information, but none is needed because there are no parameters to document. The empty schema fully covers the parameter space, so no gap exists.

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 '清除权限' is a direct Chinese translation of the tool name 'browser_clear_permissions', making it a tautology. It restates the name without providing any additional specificity about what 'permissions' means in this context. It does not distinguish itself from sibling tools like browser_clear_geolocation or browser_clear_cookies.

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 provides no guidance on when to use this tool versus alternatives. It does not mention the related browser_grant_permissions sibling or explain under what circumstances clearing permissions is appropriate. There is no hint of exclusions or prerequisites.

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