pinterest_auth

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

Discloses that it opens a browser for user authorization, which is key behavioral info. However, lacks detail on blocking behavior, side effects (token storage), or what happens after authorization. No annotations provided.

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?

Two concise sentences, front-loaded with purpose and action. No wasted words.

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?

Adequate for a simple tool with no parameters, but could be more complete by describing post-authorization behavior (e.g., callback or token handling). Lacks details on return value or effect.

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 in schema (0 params), so baseline is 4. Description does not need to add parameter info; the absence is clear.

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 'Initiate' and the resource 'Pinterest OAuth authentication flow', and distinguishes from siblings by being the only auth initiation tool among pin/board/search tools.

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 usage for starting authentication, but no explicit when-to-use or when-not-to-use guidance. The sibling pinterest_auth_status exists for checking status, but this is not mentioned.

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