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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and a closed world, so the safety profile is covered. The description adds no behavioral context of its own: no indication of what the breakdown contains, whether it is scoped to a portfolio/period, or how it is aggregated.

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, but the single sentence is duplicated verbatim with no additional information, and the remainder is boilerplate operation-ID metadata. Brevity here comes from under-specification rather than efficiency.

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 two undocumented nested parameters, no output schema, and no annotations explaining data shape, the description should carry real weight but says nothing about inputs or results. Only the describe_operation pointer hints at where an agent could recover the missing information.

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 query parameter is an open-ended object with additionalProperties, so the schema gives the agent nothing. The description does not mention any parameter, leaving the caller unable to know what filters are accepted; the referral to describe_operation is a deferral, not semantics.

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 restates the endpoint path (twice) rather than explaining what a 'status-breakdown' is or what it returns. An agent learns only that some dashboard status data exists, with no distinction from siblings like get_dashboard_metrics or get_dashboard_expense_breakdown.

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?

There is no guidance on when to use this endpoint versus the other dashboard endpoints, nor any prerequisites or exclusions. The only directive is a generic pointer to describe_operation, which applies to every tool in this set and does not help selection.

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