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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety and locality profile is fully covered structurally. The description adds only the permission-scoping note ('you can access'), which is useful but thin, and says nothing about ordering, pagination, or result size.

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?

It is a single short sentence with no waste and is front-loaded, but at seven words it is arguably under-specified rather than concise — it leaves room for another clause on scope or return shape at negligible cost.

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 would ideally say what a workspace record contains or how many to expect; instead it stops at the action. Annotations cover safety and the empty schema covers inputs, so the remaining gap is modest but real.

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 the baseline is 4; there is nothing for the description to disambiguate, and the absence of parameters is consistent with a simple enumeration call.

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 ('List') and resource ('client workspaces') with an access qualifier, which separates it from the many list_* siblings that deal with people, requests, or webhooks. It doesn't explicitly name a sibling or contrast scope, so it stops short of a 5.

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?

Usage is only implied by the verb and the 'you can access' qualifier; there is no statement of when to prefer this over list_company_people/list_members or what a workspace means in contrast to those. For a zero-argument discovery tool the implied usage is largely adequate, but no guidance is given.

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