yd_ads_add

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

No annotations provided; description discloses bulk support and optional features but not error behavior, rate limits, or other important traits.

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, efficient sentence that covers the core purpose and key features with no extra 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 tool with nested array parameters and many siblings, it lacks details on return values, prerequisites, and batch limits, but covers main capabilities.

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?

Adds context that the array is for bulk creation and that sitelink_set_id and ad_image_hash are for sitelinks and images, going beyond schema descriptions.

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?

Clearly states it creates text ads in ad groups. Mentions bulk, sitelinks, and images, which distinguishes it from sibling tools like yd_ads_add_image and yd_ads_add_dynamic.

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 creating text ads with optional sitelinks/images, but does not explicitly say when to use this vs alternatives or when not to use it.

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