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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is covered. The description adds real value beyond them by disclosing the shape of the response (permission list, feature flags, counts) and by steering tariff questions elsewhere. It does not mention auth requirements or rate limits, so not a 5.

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?

Front-loaded with the core answer ('what this account is and what the owner can do'), then the return contents, then the sibling pointer. The field enumeration is a little dense and the 'half of failures' sentence is slightly editorial, but nothing is wasted.

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?

There is no output schema, so the description must carry the return contract — and it does, listing the exact fields an agent will receive. Combined with the tariff routing note, an agent has everything needed to call and interpret it.

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 description coverage is 100% for the single workspace_id parameter, and the schema itself points to workspace://list as the source. The description adds nothing about the parameter, which is the expected baseline when the schema does the heavy lifting.

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?

Names a specific verb+resource (get account/workspace details) and enumerates exactly what it returns: name, ownership, AI-report and SSO flags, counts of folders/quizzes/members, and the caller's permission list. It also explicitly distinguishes itself from get_workspace_tariff, so an agent can route without opening either schema.

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?

Gives a concrete reason to call it — 'half of tool failures are a missing permission, and this list shows in advance what will and won't work' — and names the alternative for tariff capabilities. It stops short of stating explicit exclusions (e.g. use get_workspace_members for member rosters), but the context is clear.

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