google_ads_authorization_url

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

With no annotations, the description carries full responsibility. It only states the action (create URL) but omits behavioral details like side effects, required permissions, rate limits, or error conditions. It does not disclose that this is a read-only operation generating a URL.

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 a single sentence, which is concise, but it sacrifices necessary detail. It earns its place in terms of brevity but is too sparse for a tool with two parameters and sibling context.

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 tool's complexity (OAuth URL generation) and the presence of an output schema, the description should explain the output or setup requirements. It does not mention what the URL contains or how to use the result, leaving gaps in understanding.

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 0%, so the description must explain parameters. However, it does not mention 'state' or 'redirect_uri' at all, leaving the agent unaware of their roles or default values. The description adds no value over the raw 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 creates a Google OAuth consent URL specifically for generating a Google Ads refresh token. It uses a specific verb ('Create') and resource ('OAuth consent URL'), and the purpose is distinct from sibling tools like google_ads_exchange_authorization_code or google_ads_oauth_status.

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 is provided on when to use this tool versus its siblings (e.g., google_ads_exchange_authorization_code, google_ads_start_local_oauth_flow). It does not indicate prerequisites or context, such as needing client credentials first.

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