prepare_workspace

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

There are no annotations, so the description bears full responsibility for disclosing behavior. It does state that the operation creates or restores, which implies state changes, but it does not explain conditions, side effects, whether existing state is overwritten, or what happens on a non-fresh VM.

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 compact sentence with no wasted words. It front-loads the main action, though its brevity contributes to the ambiguity rather than resolving it.

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 combines two distinct behaviors, has no annotations, no output schema, and overlaps with restore_workspace, but the description omits the conditions that govern create versus restore, the meaning of project, and the expected side effects. These gaps make it insufficient for reliable invocation.

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 0% schema description coverage, the description needed to explain how the project parameter influences the workspace or snapshot selection, but it never mentions project at all. The agent is left with only the schema title 'Project' and default value 'default', which provides minimal semantic grounding.

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 names a concrete operation: creating a managed workspace or restoring its Drive snapshot on a fresh VM. It is clear about the resource and action, but it does not differentiate itself from the sibling tool restore_workspace, which appears to overlap with the restore behavior.

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 'on a fresh VM' implies the intended scenario, but the description never explicitly says when to use this tool versus restore_workspace, save_workspaces, or start_runtime. It also gives no guidance on when the create path should be chosen over the restore path.

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