ga4_list_google_ads_links

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

With no annotations, the description carries the behavioral burden. It conveys that this is a read-only listing operation, but it does not disclose whether property_id may be omitted, how pagination or large result sets are handled, or what happens when no links exist. The description is not misleading, but it adds little beyond the verb 'List'.

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 a single sentence with no filler or redundant information. It is appropriately concise, front-loaded with the verb and resource, and every word contributes to meaning.

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?

The tool is simple: one optional parameter and an output schema, so return values need not be described. However, the description leaves property_id semantics and usage boundaries implicit, and the absence of annotations means the agent gets no extra context. It is adequate for a minimal list tool but not fully complete.

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 description coverage is 0%, and the description only indirectly references property_id by mentioning 'GA4 property'. It does not explain the expected format (e.g., numeric GA4 property ID) or the effect of leaving it null, even though the schema marks it optional with a default of null. The description adds minimal semantic value beyond the schema.

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 uses a specific verb ('List') and a specific resource ('Google Ads accounts linked to a GA4 property'), making the tool's function unambiguous. It clearly distinguishes this tool from ga4_create_google_ads_link and ga4_delete_google_ads_link, and also from ads_list_accounts, which lists Google Ads accounts directly.

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 implies the use case: retrieving the set of Google Ads accounts linked to a given GA4 property. However, it does not explicitly state when to prefer this over alternatives such as ads_list_accounts, nor does it mention that link creation/deletion are handled by sibling tools. No exclusions or conditional guidance are provided.

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