ga4_delete_google_ads_link

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

With no annotations, the description carries the full behavioral burden, and it does well: it discloses the destructive nature, the confirm=true safety guard, the exact 403 failure mode (credential has Viewer not Editor), and the remediation path (Admin > Property Access Management, or manual deletion in GA4 UI). This goes beyond a bare 'delete' statement.

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?

Well-organized with a front-loaded purpose line followed by terse, information-dense arg explanations. Every sentence earns its place — the 403 handling and fallback are genuinely useful, not padding.

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?

Complete for a destructive unlink operation: it covers the confirm guard, the auth failure mode, the remediation, and the link_id source. The output schema frees it from explaining return values. The only gap is the unexplained property_id parameter.

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 0%, so the description must compensate. It explains link_id (from ga4_list_google_ads_links, and explicitly not the customer_id) and confirm (must be true to actually delete) — both high-value disambiguations. However, property_id is not mentioned anywhere despite being a listed parameter.

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?

States a specific verb+resource ('Remove a GA4<->Ads link') with a concrete example use case (a link pointed at a deactivated Ads account). The name itself and the example make it unambiguous against siblings like ga4_create_google_ads_link and ga4_list_google_ads_links.

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?

Gives a clear when-to-use context via the deactivated-account example and the 403/Versus-Editor scenario plus a UI fallback. However, it never explicitly states when not to use the tool or names an alternative to prefer, so usage guidance is implied rather than explicit.

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