Detach from a profile

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

Annotations already set readOnlyHint=false, destructiveHint=false, and idempotentHint=true. The description adds that the browser continues running, which explains the non-destructive nature beyond annotations. It does not detail edge cases like in-flight automation, but the provided context is sufficient for the intended use.

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?

Two sentences, zero filler. The main action is front-loaded, and the contrast with stop_profile adds critical context in the second sentence. Every word earns its place.

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?

For a single-parameter, side-effect-moderate tool with no output schema, the description is complete. It explains what the tool does, what it does not do, and how it differs from the sibling that closes the browser.

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 covers 100% of the parameter with a clear description ('Browser profile id, as passed to start_profile'). The tool description adds no further parameter information, but the schema already provides adequate meaning; 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?

Description states a specific verb and resource: 'Release the automation connection.' It clearly differentiates from sibling stop_profile by noting the browser keeps running, making its purpose unambiguous.

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?

Explicitly contrasts with stop_profile: 'use stop_profile to actually close it and sync its data directory back to the cloud.' This tells the agent exactly when to use this tool vs. the alternative.

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