setup

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

Transparently describes the authentication flow: opens browser, signs in with Google, saves key locally, and never shares it. No annotations provided, so description carries full burden.

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?

Extremely concise: two brief paragraphs with no wasted words. Front-loaded with the verb 'Authenticate' and immediately explains the process.

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 no parameters, the description covers the essential authentication behavior. Could mention if already authenticated, but overall complete for a setup 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?

No parameters exist, so schema coverage is 100%. Description adds context about the authentication flow beyond the empty schema, fulfilling the purpose.

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?

Clearly states the tool's purpose: authenticate with Datapoint AI. Explains the process: opens browser for Google sign-in and saves API key locally.

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 for initial authentication, but does not explicitly state when to use versus alternatives like checking balance or creating surveys. No exclusions or prerequisites mentioned.

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