generate_oauth_token

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

No annotations are provided, so the description carries the full burden. It discloses that the token is output to the console, the user must manually save it to an environment variable, and lists required environment variables. This provides good transparency about the manual step and prerequisites, though it lacks details on error handling or token persistence.

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 well-structured with a clear title, explanation, prerequisite list, and return description. It is front-loaded with the purpose. The environment variable list is necessary but slightly verbose; overall concise.

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 zero parameters and no annotations, the description adequately covers the tool's purpose, method, prerequisites, and output. It does not mention error cases or token lifecycle, but for a simple authentication tool it is fairly complete.

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 schema coverage is 100%. The description clarifies that there are no input parameters but instead relies on environment variables (FANFOU_API_KEY, etc.), adding meaning beyond the empty schema. It also describes the return value structure.

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 generates an OAuth token using username/password for subsequent passwordless login. It specifies the verb 'generate', the resource 'OAuth Token', and the method 'x_auth'. This clearly distinguishes it from sibling tools which focus on statuses, users, favorites, etc.

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 explains the token is for subsequent passwordless login (when to use) and lists required environment variables (prerequisites). However, it does not explicitly state when not to use this tool (e.g., if a token already exists) or contrast with alternatives, though no alternatives exist among siblings.

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