create_workspace

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

Annotations already declare this is non-read-only, non-destructive, and not open-world, so the safety profile is covered. The description adds that it targets the first empty workspace and 'effectively creates' one, but it does not clarify what happens when no empty workspace exists or whether a new workspace is actually created.

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 focused sentence with the action front-loaded and the parenthetical clarification kept brief. It contains no redundant or filler text.

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 tool with annotations and no output schema, the core invocation is clear enough. However, the vague 'effectively creates' wording leaves an important behavioral edge case unresolved: whether it fails, switches, or creates when no empty workspace is available.

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, so there are no parameter semantics for the description to explain. The empty schema is consistent with a no-argument workspace action, making the baseline of 4 appropriate.

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 specific action: switching to the first empty workspace, which clarifies the otherwise misleading create_workspace name. It does not explicitly distinguish itself from the sibling switch_workspace tool, but the 'first empty' detail gives useful specificity.

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 gives no explicit guidance about when to use this tool versus switch_workspace or next_workspace/prev_workspace. The intended use is only implied by the phrase 'first empty workspace'.

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