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

With no annotations provided, the description carries the full burden and does an excellent job: it discloses that the operation only stages a request, requires owner approval via a browser link with an agent PIN, and explicitly warns against asking for or accepting the PIN in chat. This is critical behavioral and security information beyond what the schema conveys.

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 three sentences and every sentence earns its place: purpose, behavioral staging caveat, and a security rule. The most important information is front-loaded, with no filler or redundancy.

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 ownership, staging, and the PIN rule, which is strong for a tool with no annotations and no output schema. However, it mentions 'the link' without clarifying how the link is returned, and it does not point to workspace_request_status for tracking, leaving a minor gap for follow-up behavior.

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%, so the input schema already documents name, newName, and workspace. The description adds the ownership context for workspace but does not add parameter-level semantics beyond what the schema provides, so the baseline of 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 opens with a specific verb and resource: 'Rename an access role in a workspace you own.' This clearly differentiates from sibling rename_* tools (e.g., rename_gmail_label, rename_gdrive_item) by naming the resource type and adding an ownership scope.

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 clear context: the tool is for access roles in workspaces the user owns, and it only stages a request rather than performing an immediate rename. It does not explicitly list alternative tools or when-not-to-use conditions, but the ownership and staging caveats provide enough guidance for correct selection.

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