authenticate

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

The description indicates a stateful process (authentication), conflicting with the readOnlyHint annotation marking it as read-only. This contradiction undermines transparency, and no additional behavioral details are provided.

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?

Single sentence, front-loaded with the action, each word carries meaning. No superfluous content.

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?

Adequately covers the tool's role in the authentication flow, but lacks guidance on how to handle the returned URL/code or integrate with authenticationStatus. Minor gap given tool simplicity.

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 description adds no value beyond the schema's parameter description for 'force'. Baseline of 3 is appropriate.

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 tool starts Microsoft device-code authentication and returns login URL and user code immediately, distinguishing it from sibling tools like authenticationStatus which checks status.

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?

Implies use when authentication is needed, but lacks explicit guidance on when not to use or alternatives beyond the sibling list. However, the context is clear enough for an AI agent to infer appropriate usage.

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