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

No annotations are provided, so the description carries the full burden. It identifies the operation as a bulk set (mutation) and returns a success message with count, but lacks details on idempotency, partial failures, rate limits, error handling, or whether suffixes are overwritten or appended. For a mutation tool, more behavioral context is needed.

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 concise: two sentences for purpose, then structured Args and Returns. No extraneous words. It is front-loaded with the primary purpose, making efficient use of space.

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 no annotations and no output schema, the description covers the essential calling convention and return a message with count. However, it omits details on error handling, partial success, validation, and other important behavioral aspects for a bulk mutation tool. It is adequate but incomplete for production use.

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%, so the description compensates by explaining `customer_id` format ('without hyphens') and `ad_group_suffixes` as a JSON string with an array of objects, including a concrete example. This adds significant meaning beyond the schema, though additional constraints on URL suffix format are missing.

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: 'Bulk set Final URL suffixes for multiple ad groups in one API call.' It specifies the verb 'set', resource 'Final URL suffixes for ad groups', and the bulk nature. This distinguishes it from the sibling 'google_ads_set_ad_group_url_suffix' which handles single ad groups.

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 implies usage for bulk updates by mentioning 'multiple ad groups in one API call' but does not explicitly state when to use this tool versus alternatives like the singular set tool. No when-not or exclusion criteria are provided.

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