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

No annotations provided, so description must fully disclose behavior. It omits critical details: does it block waiting for callback? What happens on port conflict? Does it open browser? Lifespan of server? These are important for an agent invoking this tool.

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?

Single sentence, front-loaded. However, it sacrifices necessary detail for brevity. Loses a point for omitting important info that could be added without bloat.

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 complexity of OAuth flow and absence of schema descriptions, description is insufficient. Lacks details on error handling, state, and expected behavior for multiple invocations. Though output schema exists, description itself is incomplete.

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 0%, yet description does not explain the 'redirect_uri' parameter at all. Agent cannot infer its purpose (e.g., where the callback should be sent) or default value significance.

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?

Description clearly states the tool starts a local OAuth callback server and returns the Google consent URL, using specific verbs and resource. It distinguishes itself from sibling tools like 'google_ads_authorization_url' which likely just returns the URL without starting a server.

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?

No guidance on when to use this tool (e.g., as first step in OAuth flow) or when not to use alternatives. Does not mention prerequisites or ordering with siblings like 'google_ads_exchange_authorization_code'.

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