zernio_get_ad_analytics

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

No annotations are provided, so the description carries full burden. It only lists metrics but does not disclose read-only status, authentication needs, rate limits, or that it might only work with certain ad platforms. For a read operation, more transparency is expected.

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?

Single sentence listing key metrics, no wasted words. Could be slightly more structured (e.g., separating input vs output), but overall efficient.

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?

No output schema, so description should hint at return structure. It lists metrics but not how they are grouped or ordered. Also does not mention default date range behavior or that dateFrom/dateTo are optional. Given many sibling tools, more context would improve completeness.

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 descriptions for all three parameters. The description does not add extra meaning beyond the schema; it only lists output metrics. No added context on date range behavior or constraints, so baseline 3 is appropriate.

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 verb 'Get' and the resource 'performance analytics for a specific ad', and lists specific metrics (impressions, clicks, CTR, spend, conversions, ROAS). This distinguishes it from siblings like zernio_get_ad (ad details) and zernio_get_ads_tree (hierarchy).

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?

No explicit when-to-use or when-not-to-use guidance. Given many sibling tools (e.g., get_daily_metrics, get_ad_interests), some context on when to choose this tool over others would be helpful. The description implies it's for a single ad but doesn't state prerequisites or exclusions.

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