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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds scoping context (connection-level permissions, workspace kind) that isn't in the annotations, though some of this overlaps with the output schema.

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 tight sentences. The returned fields are front-loaded and the relational context is saved for the closing line, so every sentence earns its place with no filler.

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?

With no parameters, rich annotations, and an output schema present, the description only needs to establish purpose and scope, which it does fully. An agent has everything required to decide to call it and know what it returns.

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 takes zero parameters, so there is nothing to disambiguate; the schema is empty and no compensation is needed. Baseline 4 applies, as the description cannot add parameter meaning where none exists.

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?

States a specific verb (Show) and resource (the Rankwise workspace), and enumerates the concrete fields returned: name, kind, role, permissions. The closing sentence distinguishes it from the many sibling tools by explaining it is the container context all other account tools operate within.

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?

"Every other account tool works inside this one workspace" strongly implies this is the orientation/entry-point call before other tools, giving clear usage context. It stops short of an explicit instruction (e.g. 'call this first') and names no when-not or alternative, so it is not a full 5.

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