deploy_vm_from_template

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

Annotations indicate a write operation (readOnlyHint=false) and no destruction (destructiveHint=false). The description adds behavioral context beyond annotations by detailing optional overrides (cpu, memory_mb) and the side effect of optionally creating a snapshot (snapshot_name). It does not contradict annotations, and the disclosure is sufficient.

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 front-loaded with a clear summary '[WRITE] Deploy...' followed by a structured parameter list. While the list is somewhat lengthy, every sentence adds value given the absent schema descriptions. Could be slightly more concise but is well-organized.

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 covers all 8 parameters, explains optional vs required, and notes behavior when omitted. However, it lacks context on error conditions (e.g., template not found) or post-deployment state (e.g., IP address, if output schema provides it). Still, it is fairly complete for a deployment tool.

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?

With schema description coverage at 0%, the description provides all parameter explanations. It adds meaning beyond the schema by specifying defaults (e.g., datastore_name uses template's datastore if omitted) and purpose of each parameter (e.g., snapshot_name: 'Create a baseline snapshot'). This is essential for correct invocation.

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 a write operation: 'Deploy a new VM by cloning from a vSphere template.' This distinguishes it from siblings like deploy_linked_clone or deploy_vm_from_ova. The specific verb 'deploy' and resource 'VM from template' make the purpose 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?

No explicit guidance on when to use this tool versus alternatives such as deploy_linked_clone, batch_clone_vms, or deploy_vm_from_ova. The description does not mention scenarios, preconditions, or exclusions, leaving the agent to infer usage context.

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