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

With no annotations, the description carries full behavioral burden. It usefully discloses the auth model (OAuth sign-in or agent API key in the Authorization: Bearer header) and warns never to pass keys as arguments, which is real added context. It says nothing about pagination, result limits, or ordering for a listing operation.

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 compact sentences, front-loaded with the action and immediately followed by the alias and the optional-parameter fact. The auth sentence is longer than needed but does carry information.

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?

For a single-optional-parameter read tool the description covers the essentials, and no output schema exists so return values need not be explained. Missing detail on what q filters and how many results come back keeps it at minimum-viable rather than complete.

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 coverage is 0%, so the description must compensate and largely does not. It only notes that q is optional; it never says what q matches against, its format, or the maxLength=80 constraint, so an agent cannot construct a useful query.

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 and resource ("List public workspaces") and explicitly names the sibling search_public_spaces, removing ambiguity about which listing tool to call. It stops short of 5 because it declares the two tools identical rather than articulating any distinguishing scope.

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 only guidance is that q is optional and that auth can be OAuth or an API key. There is no statement of when to choose this over search_public_spaces or list_my_spaces, and no exclusions or prerequisites for use.

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