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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The word "interactive" hints at a UI-rendering behavior but never explains what interactivity means for an agent (does it return a UI resource, a link, a payload?) or whether it has side effects on the session.

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?

It is short and front-loaded, but brevity here is under-specification rather than economy: a single five-word sentence carries no information an agent could act on.

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?

With an output schema present, return values need not be described, but six undescribed filter params, an enum, and an indistinguishable sibling leave the definition far too thin. Nothing tells the agent what data the console surfaces or how the filters interact.

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?

Six parameters with 0% schema description coverage and the description mentions none of them. Nothing explains that since/until/date_preset are mutually exclusive date filters, what campaign_ids or ad_account_ids scope, or that ad_account_id and ad_account_ids are two forms of the same filter.

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?

"Show an interactive ads console" largely restates the tool name and title without naming the resource scope or what the console does. A sibling named open_ads_console exists, but the description gives no basis for choosing between "render" and "open", so the agent cannot distinguish them from the text alone.

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 when-to-use, when-not-to-use, or alternative guidance is given. With open_ads_console and console_query_overview, console_export_csv, and render_performance_report as near neighbors, the absence of routing guidance is a real risk of mis-selection.

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