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

Annotations already indicate non-read-only and idempotent, and the description adds the distinction between permanent (config-based) and session-only (token paste) connections. It doesn't detail side effects like token expiry or revocation, but it offers context beyond annotations. No contradiction found.

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, long run-on sentence that packs a lot of information but is somewhat convoluted. It is front-loaded with the IDE agent context, which might be essential but could be trimmed. The structure mixes instructions and options without clear separation.

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 a simple schema (one optional param), no output schema, and supportive annotations, the description covers the essential workflow: browser login, token acquisition, and two integration methods. It doesn't explain return values, but that's not required. Overall, it's adequate for a straightforward auth tool.

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 schema has one optional 'token' parameter with no description (0% coverage). The description compensates by clarifying that the token is a JWT and explains that it's used for session-only login, while no args returns the login link. This adds meaningful semantics to the parameter.

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's purpose: authenticate by logging in via browser and obtaining an access token. It distinguishes between two usage modes (permanent config vs. session token) and separates it from siblings like 'connect' by focusing on user login. However, the opening 'MCP.AI for IDE agents' adds context that slightly muddies the core action.

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?

Provides explicit instructions: log in in the browser, copy token, and choose between adding as header for permanent access or pasting for session-only. It also explains how to invoke (with or without token). Lacks explicit 'when not to use' but gives clear operational guidance.

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