Activate duo

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

Annotations already state readOnlyHint=false, openWorldHint=true, and destructiveHint=false, so the safety profile is partly covered. The description adds that this may update existing Duo setup and supports Duo OIDC, but it does not disclose permissions, side effects, or authentication requirements.

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 single sentence is front-loaded, direct, and free of filler. However, it is arguably too terse for a configuration mutation with opaque parameters.

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 non-read-only, open-world 2FA configuration tool with three undocumented parameters and no output schema, the description leaves major gaps. It does not explain expected input shape, authorization, effects on existing Duo configuration, or return behavior.

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?

There are 3 parameters with 0% schema description coverage, and the description says nothing about what form, params, or json_body should contain. It does not compensate for the schema's lack of type or field-level detail.

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 a specific verb+resource: 'Enable/update Duo (or Duo OIDC) 2FA.' It is clear what the tool does, but it does not distinguish itself from close siblings such as vaultwarden_activate_duo_put or vaultwarden_get_duo.

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 'Enable/update' implies activation or update, but there is no explicit guidance on when to use this tool versus get_duo or activate_duo_put, nor any prerequisites or when-not-to-use conditions.

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