users_activate

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It conveys the state change (reactivation) but omits important details such as required permissions, reversibility, error handling, and whether the operation is idempotent.

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 a single, front-loaded sentence with no wasted words. It is appropriately sized for the tool's simplicity and immediately communicates the core action.

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 simple one-parameter state-change tool, the description is minimally adequate. However, since there is no output schema or annotations, it leaves gaps around return behavior, error cases, and whether activation is idempotent, so it falls short of fully complete guidance.

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 input schema covers 100% of the parameters with the description 'User ID to activate.' The tool description adds no additional semantic detail beyond identifying the target as a suspended user account, so the schema already carries the meaning.

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 uses the specific verb 'Re-activate' and the explicit resource 'suspended user account,' making the tool's purpose unmistakable. It clearly distinguishes itself from sibling tools like users_suspend and users_update.

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 phrase 'a suspended user account' provides clear context that this tool should only be used when a user is suspended, implying it is the inverse of users_suspend. However, it does not explicitly name alternatives or state exclusions for already-active users.

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