gads_searchRun custom GAQL queries against Google Ads data. Use for advanced analysis—filter by keywords, matching types, or aggregate metrics by custom dimensions.

+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, so the description need not repeat these. The description adds no behavioral traits beyond annotations, but does not contradict them. A score of 3 is appropriate as the description adds marginal behavioral context.
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: one for the core action, one for usage context. It is front-loaded, concise, and contains no redundant information. Every sentence adds value.
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 presence of an output schema and comprehensive annotations, the description adequately covers usage context. It could mention return format or limitations, but completeness is high for a tool with strong structured metadata.
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%, with both parameters documented. The description adds examples of filtering and aggregation, providing context beyond schema but not essential new semantics. Baseline 3 is justified as the schema does the primary work.
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 runs custom GAQL queries against Google Ads data, using specific verbs and resource. It distinguishes from sibling tools like gads_campaign_metrics by emphasizing advanced analysis and custom dimensions, making the purpose 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?
The description provides clear context for usage using 'Use for advanced analysis' and examples, but does not explicitly state when not to use this tool versus alternatives like gads_campaign_metrics or gads_list_campaigns. The guidance is adequate but lacks exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
