Begin Microsoft 365 Auth

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

No annotations are provided, so the description carries full burden. It only says 'start' without explaining the device-code flow, user interaction required, or what the tool returns. This lacks transparency about the process and side effects.

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, concise sentence that directly states purpose without unnecessary words. It is front-loaded and efficient.

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?

Given the tool's complexity (initiating an authentication flow), the description is insufficient. It omits expected return values, required user action (e.g., entering device code), and how to proceed after the call. An output schema or more descriptive text would improve completeness.

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 has zero parameters (100% coverage by schema). For zero-parameter tools, the baseline is 4. The description adds no param-level details, but no details are needed.

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 'Start Microsoft 365 device-code login for the local Claude Desktop MCP process.' It uses a specific verb ('Start') and resource ('Microsoft 365 device-code login'), and distinguishes itself from siblings like 'auth_status' which likely checks authentication state.

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 description indicates the tool's function (initiate device-code login) but provides no explicit guidance on when to use it versus alternatives like 'auth_status'. It does not mention prerequisites or when not to use it.

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