ga4_create_search_ads_360_link

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

With no annotations, the description must fully disclose behavior. It indicates it's a write operation ('[GA4 WRITE]') and requires confirm=true, but it does not describe side effects (e.g., whether it creates a new link or updates an existing one), error conditions, idempotency, or what happens upon success.

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 extremely concise: one sentence and a parenthetical. It front-loads the write indication and the action. While efficient, it sacrifices completeness of information, but for pure conciseness it is well-structured.

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 it is a write tool with 4 parameters, no output schema, and many sibling tools, the description is insufficient. It lacks information on prerequisites, return values, and behavioral context. The schema provides partial parameter help, but the description adds minimal holistic 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 high (75%), so the baseline is 3. The tool description adds no additional meaning beyond the schema's own descriptions. The 'advertiserId' parameter lacks a schema description, and the tool description does not clarify its purpose.

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 states 'Create a Search Ads 360 link' with a clear verb and resource. It is specific enough to distinguish from sibling tools like ga4_delete_search_ads_360_link or ga4_create_google_ads_link, though it does not elaborate on what a Search Ads 360 link is or its purpose.

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 versus alternatives such as ga4_create_google_ads_link or ga4_create_firebase_link. The only prerequisite mentioned is the environment variable and confirm parameter, but no context on typical use cases or when to avoid this tool.

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