ga4_create_search_ads_360_link

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

With no annotations provided, the description relies solely on '[GA4 WRITE]' to indicate a write operation and the 'confirm=true' requirement. It does not disclose side effects, permissions, or other behavioral traits beyond the basic write nature.

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 very concise: one sentence for purpose plus a note on requirements. It is front-loaded and wastes no words, though it could include more context without being verbose.

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 output schema and a nested 'body' parameter, the description does not explain what the body should contain, what the advertiserId is, or what the tool returns. It is insufficient for an agent to use correctly without referencing additional documentation.

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 75%, so the schema already documents most parameters. The description adds no extra parameter semantics, leaving the agent to rely on schema descriptions alone.

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 Search Ads 360 link, with a specific verb ('Create') and resource ('Search Ads 360 link'), distinguishing it from sibling tools like ga4_create_google_ads_link.

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 mentions required conditions (GA4_MCP_ENABLE_WRITES=true, confirm=true) but provides no guidance on when to use this tool versus alternatives like ga4_update_search_ads_360_link or other link creation tools.

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