get_cloudinit_config_vm

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

With no annotations, the description carries the full burden. 'Fetch' clearly signals a read-only operation, but no additional context is given about response format, error conditions, or prerequisites. The behavior is basic and evident, but not elaborated beyond the verb.

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, front-loaded sentence with no filler. Every word earns its place, and it is appropriately sized for a simple getter tool.

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?

The tool is simple (2 params, no output schema), so the description is minimally adequate. However, it lacks parameter semantics, output expectations, and any note about error handling or prerequisites. Clear gaps remain, making it only a baseline viable description.

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 description coverage is 0%. The description does not mention 'node' or 'vmid' at all, leaving both parameters completely undocumented. It only says 'of a virtual machine', which does not clarify parameter meaning, required fields, or value formats.

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 specific verb 'Fetch' with the resource 'Cloud-Init configuration settings of a virtual machine', clearly distinguishing it from the sibling get_vm_config (which fetches all config) and configure_cloudinit_vm (which modifies config). The scope is 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?

The description implies usage when Cloud-Init settings are needed, but does not explicitly state when to prefer this over get_vm_config or contrast with configure_cloudinit_vm/regenerate_cloudinit_vm. No exclusions or alternative guidance is provided, so guidance is merely implied.

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