Get Polar OAuth URL

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds that it generates a URL, consistent with these hints. No additional behavioral traits are disclosed, but annotations cover the main safety and idempotency aspects.

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 very concise (two sentences) and front-loaded with the purpose. It effectively communicates the core function and usage context, though could be slightly expanded to cover parameter semantics without losing conciseness.

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 output schema exists and the tool is simple, the description is mostly adequate. However, it omits mention of the response_format parameter controlling output format, which is relevant for an agent to properly handle the response.

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?

Schema description coverage is 67% (state and scopes have descriptions, response_format does not). The description does not add any parameter details beyond what the schema provides, failing to compensate for the missing response_format description.

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 verb 'Generate' and resource 'Polar OAuth authorization URL'. It distinguishes from sibling tools by specifying 'Use this first when no local token exists.' indicating the tool's role in the OAuth flow.

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 provides explicit guidance: 'Use this first when no local token exists.' This implies the workflow order relative to polar_exchange_code, but does not mention scenarios where a token already exists or alternatives.

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