subaccount_get_status_overview

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It says the tool returns a 'comprehensive overview' but doesn't disclose what specific statuses or metrics are included, whether it aggregates across all subaccounts, whether it requires any special permissions, or what the output structure looks like. The phrase 'comprehensive overview' is vague and doesn't add meaningful behavioral detail beyond the name.

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 short and front-loaded with the main purpose, but the 'Returns:' section is redundant with the first sentence and adds no new information. It's not bloated, but the second line is filler that doesn't earn its place.

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?

For a zero-parameter read-only overview tool, the description is mostly adequate, but it lacks specificity about what 'statuses and key metrics' actually means. The output schema exists and may compensate for return-value details, but the description doesn't clarify the scope (e.g., all subaccounts in the account) or any filtering/aggregation behavior. It's minimally viable but leaves an agent guessing about the exact nature of the overview.

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?

The tool has zero parameters, so there is no parameter semantics burden on the description. The schema coverage is 100% (vacuously), and the description correctly implies no inputs are needed. Baseline 4 is appropriate for a no-parameter tool.

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 states a specific verb ('Get') and resource ('overview of all subaccount statuses and key metrics'), which clearly identifies the tool's function. It distinguishes itself from sibling tools like subaccount_find_by_email and subaccount_get_balance_summary by focusing on statuses and health metrics, though it doesn't explicitly name those siblings.

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 implies this is the go-to tool for a high-level subaccount health overview, but it doesn't explicitly state when to use it versus alternatives like subaccount_get_balance_summary or subaccount_monitor_usage. There is no exclusion guidance or mention of prerequisites, but the context is reasonably clear for a zero-parameter overview tool.

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