ga4_acknowledge_user_data_collection

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 discloses that this is a write operation ('[GA4 WRITE]') and that it is required once for certain operations. However, it does not describe the outcome, reversibility, or response format, leaving some behavioral aspects unclear.

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 two sentences long with no wasted words. It is front-loaded with the purpose and efficiently provides usage context and requirements. Every sentence serves a purpose.

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 simplicity and lack of output schema, the description covers purpose, usage context, and requirements. It could mention the expected response (e.g., success acknowledgment), but overall it is sufficiently complete for an agent to use it correctly.

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?

The schema has 50% coverage (property described, confirm not). The description adds value by noting that 'confirm=true' is required, which goes beyond the schema. The property parameter is standard and the schema description suffices.

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: to acknowledge that the property owner has the required user privacy disclosures/rights. It uses a specific verb ('Acknowledge') and resource, and distinguishes from sibling tools by explaining it's a prerequisite for other operations like creating links or MP secrets.

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 explicitly mentions when to use it: 'Some operations (e.g. creating certain links or MP secrets) require this once.' It also lists prerequisites: 'Requires GA4_MCP_ENABLE_WRITES=true and confirm=true.' However, it doesn't specify when not to use it or provide alternatives.

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