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

Annotations declare readOnlyHint=true, non-destructive, and closed-world, which covers the safety profile. The description adds nothing beyond that: it does not say whether opening the console is a navigation action, whether it renders state, whether it is idempotent, or what happens with no arguments since required parameters are zero. It does not contradict the annotations, but it contributes no 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?

It is a single, front-loaded sentence with no filler, which is structurally fine. However the brevity comes at the cost of omitted required information rather than from tight editing, and it chooses the wrong noun for the resource.

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?

Four undocumented parameters, no annotations-level elaboration, a mismatch between tool name and described resource, and no mention of the output schema despite it existing. For a tool an agent must call with specific IDs and dates, this is insufficient to invoke correctly.

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% across four parameters (date_to, date_from, product_ref, connection_context), and the description mentions none of them. Pattern and length constraints exist in the schema but no parameter is explained anywhere, so an agent must guess that product_ref and the date range scope which dashboard is opened.

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 name says 'open_ads_console' and the title is 'Ads Console', but the description says it opens the 'product Insights dashboard'. The name, title, and description disagree about what is being opened, and the sibling list contains both console_* tools and insights_* tools as well as render_ads_console. An agent cannot tell from the text whether this opens an ads console, an insights dashboard, or something else.

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, no when-not-to-use, and no mention of any alternative among the many console_*, insights_*, and render_* siblings. The single sentence gives no routing information at all.

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