configure_cloud_init

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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it does reveal the key side-effect of changes taking effect on next boot and the requirement for at least one parameter. However, it omits whether the configuration overwrites or merges with existing cloud-init settings, and lacks error-handling or prerequisite details like requiring cloud-init to be installed.

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 exceptionally well-structured: a summary sentence, a critical constraint, and a neatly formatted Args list. Every sentence earns its place, and the layout is highly scannable.

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 description thoroughly covers the tool's purpose, key constraint, and all parameters, and since an output schema exists, return values need not be detailed. It falls short only by not addressing whether configuration merges with or overwrites existing settings, and omitting any prerequisites like requiring a cloud-init-enabled OS image.

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?

Despite 0% schema description coverage, the Args section comprehensively documents all seven parameters with rich context, including formats and examples (e.g., ip_config's 'ip=dhcp' or 'ip=10.0.0.5/24,gw=10.0.0.1'), encoding notes for ssh_keys, and units for nameserver. This fully compensates for the schema's lack of descriptions.

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 clearly states it configures cloud-init settings for automated provisioning on a VM, using a specific verb and resource. This unambiguous scope distinguishes it from sibling tools like list_vms, create_snapshot, or start_guest, none of which handle cloud-init configuration.

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 provides clear operational context, noting that 'At least one parameter must be provided' and that changes take effect on next boot, which helps an agent decide when to invoke it. However, it does not explicitly name alternatives or state when not to use this tool versus a sibling, though the unique purpose makes this less critical.

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