Enable user

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

Annotations already declare this is not read-only and not destructive; the description adds only that the target account must be disabled. It omits admin permission requirements, idempotency, side effects, reversibility, and what happens if the account is already enabled.

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 as concise as possible while still naming the core operation.

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 an admin mutation tool with four undocumented parameters and no output schema, the definition is too sparse. It gives the basic intent but lacks permissions, parameter mapping, and behavioral details needed for reliable invocation.

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 0%, with four parameters and no descriptions. The definition says 'user account' but does not explain user_id or the generic form, params, and json_body fields, so it does not compensate for the schema gap.

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 states a specific verb ('re-enable') and resource ('disabled user account'), making the operation clear. It implicitly contrasts with disabling a user but does not explicitly differentiate from siblings such as vaultwarden_disable_user or vaultwarden_delete_user.

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?

Usage is only implied by 'disabled user account': the agent can infer this applies to accounts that are currently disabled. There is no explicit when-not guidance, prerequisite, or named alternative for re-enabling versus other user-management actions.

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