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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description's "[read]" tag merely duplicates readOnlyHint, and its only added signal is that results are scoped to the caller's memberships. Nothing is said about ordering, pagination, or whether an empty list is returned for unaffiliated users.

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?

Six words, front-loaded, with zero filler — appropriate for a parameterless read. It stops short of being ideal only because the brevity shades into under-specification rather than pure economy.

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?

Annotations and the empty schema make the call mechanics unambiguous, but there is no output schema and the description never indicates what a workspace record contains (id, name, slug). An agent needs an identifier from this call to chain into project-scoped siblings, and that must currently be guessed.

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, which is the baseline-4 case; there is nothing for the description to disambiguate. Coverage is nominally 100% because there is nothing to cover.

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 workspaces you are in" names the resource and implies listing, but the verb comes only from the tool title/name rather than the description itself. The membership scoping ("you are in") is a useful qualifier, though the phrase reads as a fragment restating the name. It is sufficient to know roughly what comes back but offers no differentiation from the many other list_* siblings.

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?

There is no statement of when to call this versus the other list_* tools (list_projects, list_assets, list_media, list_templates) or whether a workspace must be selected before using project-scoped tools. The agent must infer the trigger condition entirely.

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