disconnect

End the active backend connection for the current CFX leaf, stopping any ongoing operations and freeing resources. Use this when you need to cleanly close the connection before starting a new workflow.

Instructions

Disconnect the cfx leaf's active backend.

TDQS

A3.5/5.0
Behavior2/5

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

With no annotations, the description carries the full burden of disclosing side effects. It only states the action without mentioning whether it is destructive, requires authentication, or what happens if there is no active backend. This is insufficient for a mutating operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one concise sentence (7 words), front-loads the verb, and contains no unnecessary text. It is perfectly sized for the tool's simplicity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is adequate for basic understanding but lacks usage context (when to call) and behavioral details (side effects). While the tool is simple and output schema exists, the lack of guidance reduces completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so the schema trivially covers all inputs. The description adds no parameter details, but none are necessary; baseline 4 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the action ('Disconnect') and the target resource ('cfx leaf's active backend'), which is specific and distinguishes it from sibling tool 'connect' as the inverse operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool vs alternatives, such as prerequisites, whether to call after 'connect', or behavior when no active backend exists. This is a clear gap for a tool with a direct counterpart.

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