get_vm_cloudinit

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

The description is minimal and does not disclose behavioral traits such as error handling, behavior when the VM has no cloud-init config, or read-only nature. With no annotations to compensate, more detail is needed.

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 very short and to the point, with no wasted words. The purpose is stated first, followed by parameter descriptions. It could be slightly more structured (e.g., separate lines), but it is efficient.

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 has a simple signature with two required parameters and an output schema (not shown), so the description is somewhat complete. However, it omits context about sibling tools and potential errors, which would improve usability.

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 description adds 'The node name' and 'The VM ID' to the parameters, which are not present in the schema titles alone. However, given the low schema coverage (0%), more detailed semantics (e.g., format, constraints) would be beneficial.

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 the tool retrieves Cloud-Init configuration for a VM. While there is a sibling tool 'dump_vm_cloudinit' that may serve a similar purpose, the description does not differentiate them, but the core function is well-defined.

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?

No guidance is provided on when to use this tool versus alternatives like 'dump_vm_cloudinit'. The description lacks context on prerequisites or typical use cases, leaving the agent without direction.

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