flow_disconnect

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

With no annotations, the description declares the primary actions (closing browser, cleaning up connection) but does not disclose side effects such as terminating active sessions or preventing further operations. This is adequate for a simple cleanup tool but lacks deeper behavioral context.

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, well-structured sentence that directly states the tool's function without unnecessary words. It is perfectly concise and front-loaded.

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 parameterless tool with no output schema or annotations, the description provides the essential information about its role as a disconnect/cleanup operation. It lacks explicit usage context but is otherwise complete for its simplicity.

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 tool has zero parameters and an empty schema, so the description adds nothing about parameters. Since there are no parameters to explain, the baseline of 4 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 specific verbs 'Close' and 'clean up' to describe the resource (browser and MCP connection), clearly indicating this is the teardown counterpart to flow_connect. It distinguishes itself from sibling tools by its focus on disconnection and cleanup.

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 does not explicitly state when to use the tool or contrast it with alternatives like flow_connect. Usage must be inferred from the name and context, so the agent receives no direct guidance.

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