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

With no annotations, the description fully discloses behavior: it stages a request requiring owner approval via a link and PIN, warns never to ask for the PIN in chat, and notes reversibility. This covers the async nature, security implications, and side effects (agent stops, admin powers off) thoroughly.

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?

The description is efficient and front-loaded with the primary action and effect, then covers the async approval process and security warning. Every sentence adds essential information without redundancy, making it easy for an agent to parse quickly.

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?

The description covers the core behavioral aspects: ownership requirement, inability to pause owners, async approval, and PIN security. It does not explicitly state what the tool returns (e.g., a link) but implies it by saying 'the owner opens the link.' Given no output schema, this is acceptable, though mentioning the return format would make it more 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 100% with clear per-parameter descriptions, so the baseline is 3. The description adds value by explaining the workspace parameter is only needed when owning multiple workspaces and reiterates paused=false means resume, reinforcing the schema. It does not introduce new parameter details beyond what the schema already provides, but the added ownership context justifies a 4.

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 description clearly states the action: pause a member of a workspace you own, with a specific effect (agent stops working, admin powers off) and reversibility (paused=false resumes). It distinguishes itself from sibling tools like remove_member by emphasizing temporary suspension, and notes owners cannot be paused, adding precision.

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 description provides clear usage context: you must own the workspace, and owners themselves cannot be paused. It implies this is for temporary suspension rather than removal, but does not explicitly name alternatives like remove_member or set_member_workspace_role. The async approval process is well explained, giving the agent a strong sense of when to call this tool.

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