Who am I

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

With no annotations, the description must disclose behavioral traits. It states the tool returns 'authenticated user and their workspaces' and hints at being read-only, but does not detail response format, authentication requirements, or potential side effects. Some context is provided, but more specificity would elevate clarity.

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?

Two sentences with no filler. Front-loaded with the primary purpose followed by actionable guidance. Every word earns its place.

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 no annotations, output schema, or parameters, the description is mostly complete. It explains what the tool does and why it matters. Minor gaps: could mention the response includes user ID and workspace details, or explicitly state it's a safe read operation.

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 no parameters (schema coverage 100% automatically). The description adds semantic value beyond the empty schema by explaining what the output represents ('authenticated user and their workspaces') and its practical use (providing workspace_gid).

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 explicitly states 'authenticated user and their workspaces' and adds usage context ('Call this first'). It clearly differentiates itself from sibling tools like project_create or member_list by indicating it provides the workspace_gid needed for create operations.

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 guidance: 'Call this first — almost every create call needs a workspace_gid.' This tells the agent when to use the tool and its purpose. It does not explicitly state when not to use it (e.g., if workspace_gid already known), but the positive guidance is strong.

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