Activate Member

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

Annotations already mark this as a non-read-only, non-destructive mutation, and the description adds two facts annotations cannot convey: the required role (workspace admin or owner) and that existing roles are preserved on reactivation. It stops short of noting idempotency or behavior when the user is already active.

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?

One core sentence plus a short permission clause, with the effect front-loaded and zero filler. Every phrase carries 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?

With an output schema present and a fully documented single parameter, the description supplies what structured fields cannot: the permission requirement and the role-preservation guarantee. Only edge-case behavior (already-active user, failure modes) is left out, which is a minor gap for a one-parameter tool.

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% and the single 'user' parameter is fully documented in the schema as email or user id. The description adds no additional parameter guidance, which is the expected baseline when the schema does the work.

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?

Specific verb+resource: re-enable sign-in for a previously deactivated person, and it names the counterpart tool (deactivate_member) so the pair is unambiguous against 50+ siblings. The added detail that roles are restored 'as before' further pins down the effect.

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?

Explicitly scopes the tool to people deactivated via deactivate_member and states the permission prerequisite (workspace admin or owner). It does not say what to do for never-activated users or non-deactivated targets, so a minor inference remains.

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