ga4_delete_google_ads_link

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

With no annotations, description only mentions required flag and confirmation. Does not disclose irreversibility, side effects, permissions, or return behavior.

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?

Extremely concise: one sentence with all essential information. No wasted 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?

Covers purpose and key prerequisites, but lacks details on return values, error handling, or permission requirements. Adequate for a simple delete tool with good schema coverage.

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 100%, so baseline is 3. Description adds minimal context: 'Full resource name' for name and 'Must be true to delete' for confirm, but does not elaborate further.

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?

Description clearly states 'Delete a Google Ads link', providing a specific verb and resource. Though it does not explicitly distinguish from sibling tools like 'ga4_create_google_ads_link', the action is unambiguous.

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 through prerequisites (requires GA4_MCP_ENABLE_DELETES=true and confirm=true), but does not provide guidance on when to use versus alternatives or when not to use.

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