get_auth_url

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

No annotations present, so description carries the burden. It describes a non-destructive, read-only operation (generating URL) and mentions the OAuth flow, but does not explicitly state lack of side effects or security considerations.

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?

Three sentences, front-loaded with the core purpose, no wasted words. Efficient and clear.

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?

Complete for a simple 0-parameter tool, covering purpose and next step. However, it does not explicitly describe the output format (though implied it's a URL). Minor gap.

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, schema coverage is 100%. The description adds context about the URL's purpose and usage, going beyond the schema.

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 authorization URL, using a specific verb and resource. It distinguishes from sibling tools like exchange_code by describing the next step.

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?

Explicitly explains the workflow: open URL in browser, authorize, copy code, pass to exchange_code. Provides clear when-to-use and sequential guidance.

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