browser_disconnect

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action 'Disconnect from a specific browser tab' without mentioning side effects, prerequisites, error behavior, or what happens to the tab. This is minimal transparency.

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 phrase with no wasted words. It is front-loaded and concise, but it lacks full sentence structure and contextual detail. As a result, it is concise but slightly under-specified.

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 simplicity (one parameter, no output schema) and lack of annotations, the description is insufficient. It does not explain what 'disconnect' does to the tab, when it should be used, or what the return value is. More context is needed for an agent to use it correctly.

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 schema already documents the 'tabId' parameter with a clear description, and schema coverage is 100%. The tool description adds no additional meaning beyond the schema, so the schema carries the load. A baseline of 3 is appropriate.

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 uses the verb 'Disconnect' and identifies the resource 'browser tab', making the action clear. It subtly distinguishes from sibling tool 'browser_connect' by describing the opposite action, but it does not elaborate on what 'disconnect' entails (e.g., closing a debugging session), so it is not fully differentiating.

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 usage guidance is provided. The description does not mention when to use this tool, any prerequisites (e.g., the tab must already be connected), or alternatives, leaving the agent to infer from the name and sibling tools.

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