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

Goes well beyond the annotations (readOnlyHint=false, destructiveHint=false, openWorldHint=false) by disclosing that this is only a staged request requiring the owner to open a browser link and approve with their agent PIN, plus the hard constraint never to ask for or accept the PIN in chat. That is exactly the kind of non-obvious behavior an agent must know before invoking.

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?

Four sentences, each load-bearing: effect of pausing, how to resume, the owner exclusion, and the approval/PIN workflow. The most decision-relevant fact (what pausing does) is front-loaded 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?

No output schema exists, and the description compensates by explaining the full approval lifecycle the agent will trigger, including where the request goes and that it is not applied immediately. Nothing needed to call this correctly is missing.

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%, so the schema already documents email, paused, and workspace, including 'true to pause, false to resume'. The description restates the paused=false resume semantics but adds no syntax or format detail beyond the schema, so the baseline 3 applies.

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 ('Pause a member of a workspace you own') and immediately defines the exact semantics: member stays, agent stops working, admin powers off. This clearly separates it from siblings like remove_member or set_member_workspace_role.

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 the resume path ('Pass paused=false to resume'), the ownership precondition ('a workspace you own'), and an exclusion ('Owners can't be paused'). It doesn't explicitly name the sibling alternative (remove_member) for when pausing is the wrong choice, but the context is unambiguous.

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