create_auth_url

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

With no annotations, the description covers the basic flow: returns a URL, user opens it in browser, account appears after approval. However, it omits behavioral details like rate limits, permissions, idempotency, or what happens if already connected.

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 two sentences, front-loaded with the core action, and every sentence adds value. 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?

For a simple tool with three parameters and a single URL output, the description explains the entire flow: initiating OAuth, using the URL, and the result. It is complete and actionable.

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 coverage is 100% with descriptions for each parameter. The tool description adds context about the OAuth flow but does not explain parameter formats or constraints beyond the schema, so it meets the baseline without adding significant value.

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's purpose: start an OAuth connect flow and return a URL to authorize an account. It distinguishes from siblings like create_social_account by specifying the flow and the result (account appears in list_social_accounts).

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 says 'Use this to connect a new Instagram/TikTok/X/etc.' which indicates when to use, but it does not explicitly state when not to use or mention alternative tools (e.g., create_social_account might be for direct API keys). This lacks comprehensive guidance.

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