oauth_login

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

No annotations are provided, and the description does not disclose behavioral traits such as side effects (e.g., creating a session, redirecting the user), required user interaction, or success/failure states. The agent has no idea what invoking this tool entails.

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 extremely short (two lines) but lacks substantive content. While brevity is good, it sacrifices clarity entirely, making it non-informative.

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 absence of parameters, output schema, and annotations, the description must fully explain the tool. It fails to convey what the tool does, its prerequisites, or its outcomes, leaving the agent completely uninformed.

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, so the description cannot add meaning beyond it. The baseline for high schema coverage is 3, and the description does not harm understanding, but it also provides no useful parameter context.

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?

Description is essentially a restatement of the tool name ('Oauth Login') with an endpoint hint. It does not specify what action the tool performs (e.g., initiates OAuth flow, returns a URL, or handles credentials). Among siblings like oauth_callback, get_token, and refresh_token, it fails to distinguish its role.

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?

No guidance on when to use oauth_login versus alternatives like oauth_callback, get_token, or create_api_token. The description does not indicate whether this is the first step in authentication or requires prior user interaction.

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