cldkctl_vm_turn_off

Turn off a virtual machine in Cloudeka by providing its VM ID. This tool helps manage cloud resources by shutting down specific VMs when not needed.

Instructions

Call the cldkctl_vm_turn_off endpoint

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

D1.7/5.0
Behavior1/5

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

No annotations are provided, so the description must fully disclose behavioral traits. It fails to mention that this is a destructive operation (turning off a VM), potential side effects, required permissions, or any rate limits. The description adds no value beyond the obvious implication from the name.

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

Conciseness2/5

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

While the description is concise with one sentence, it is under-specified and wastes the opportunity to convey useful information. It fails to front-load critical details, making it inefficient rather than appropriately sized for its purpose.

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

Completeness1/5

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

Given the complexity of a VM management tool with no annotations and no output schema, the description is completely inadequate. It lacks essential details about behavior, usage, and outcomes, failing to compensate for the missing structured data and leaving the agent poorly informed.

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

Parameters3/5

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

Schema description coverage is 100%, with the single parameter 'vm_id' well-documented in the schema. The description adds no additional meaning or context about the parameter, such as format examples or constraints, so it meets the baseline score of 3 where the schema does the heavy lifting.

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

Purpose2/5

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

The description 'Call the cldkctl_vm_turn_off endpoint' is a tautology that merely restates the tool name without explaining what the tool actually does. It doesn't specify the action (turning off a VM) or differentiate it from sibling tools like 'cldkctl_turn_off_vm' or 'cldkctl_vm_reboot', leaving the purpose vague.

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

Usage Guidelines1/5

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

There is no guidance on when to use this tool versus alternatives. The description provides no context about prerequisites, appropriate scenarios, or comparisons with sibling tools like 'cldkctl_vm_reboot' or 'cldkctl_vm_delete', making it misleadingly incomplete for an agent.

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