Open workspace

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

The description adds little beyond the readOnlyHint annotation. 'Open' implies a read operation, consistent with the annotation, but it does not clarify what 'open' entails (e.g., loading config, validating path) or mention any side effects or permissions 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 a single, front-loaded sentence with no extraneous words. It efficiently communicates the core action and result.

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?

Given the simple parameters, full schema coverage, and presence of an output schema, the description is mostly complete. It could explicitly state that the workspaceId is for subsequent operations, but this is minor.

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?

Schema coverage is 100% with descriptions for both parameters. The tool description does not add meaning beyond the schema. Baseline 3 is 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 verb ('Open') and resource ('allowed local checkout workspace') and mentions the return value ('workspaceId'). It distinguishes from sibling tools like workspace_status and workspaceguard_info by focusing on opening a workspace for checkout.

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. It does not specify prerequisites, when to use workspace_open vs. workspace_status, or scenarios where opening a workspace is appropriate.

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