Sb3 Vm Load

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

With no annotations, the description carries the full behavioral disclosure burden. It reveals that the operation is proxied and targets the headless VM, but it does not state whether loading replaces existing VM state, is idempotent, or what happens if no project is open.

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?

A single sentence with no filler. The key object ('open project') and destination ('headless VM') are front-loaded, and the parenthetical 'proxied' adds useful context without bloating the description.

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?

For a zero-parameter action with an output schema, the description is close to sufficient. However, it omits the prerequisite that a project must be open and does not clarify its position in the VM workflow, so an agent could invoke it at the wrong time.

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 tool has zero parameters, and the schema is complete with 100% coverage. There is nothing for the description to add semantically, so the baseline of 4 applies.

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 states a clear action and object: load the open project into the headless VM. The verb 'load' distinguishes it from execution-oriented siblings like sb3_vm_run, though it does not explicitly differentiate itself from related project/VM tools.

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 phrase 'the open project' implies a prerequisite that a project must already be open and suggests this precedes VM execution. However, the description never explicitly states when to use this tool versus sb3_open_project, sb3_vm_run, or other VM lifecycle tools.

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