get_complete_financial_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 only lists data categories and says nothing about side effects (though likely a read-only operation), response format, data freshness, or any caveats. This lack of behavioral detail leaves the agent uncertain about safety and expectations.

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 a single sentence that front-loads the core value ('Comprehensive financial overview') and then efficiently enumerates the covered areas. Every word earns its place, and it is appropriately sized for a tool with no parameters and no complex behavior.

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?

Given the tool's low complexity (no parameters, no output schema), the description provides a reasonable overview by listing the major data sections. However, it does not specify the exact return structure or whether the data is summarized or detailed. Since there is no output schema, the description could have added a bit more about the shape of the response, but it is largely sufficient for an agent to anticipate a combined payload.

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, and the schema is an empty object, so schema coverage is trivially 100%. According to the baseline rule for 0-parameter tools, a score of 4 is appropriate—there are no parameter semantics for the description to clarify, and the description does not need to compensate for any schema gaps.

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 identifies the tool as a comprehensive financial overview that aggregates accounts, net worth, cashflow, budgets, and recurring transactions. The phrase 'in one call' distinguishes it from the many single-purpose sibling tools like get_accounts, get_net_worth, and get_budget_summary, making the purpose unmistakable.

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 when to use this tool: when you need a broad, combined financial picture without making multiple separate calls. It does not explicitly name alternatives or exclusion criteria, but the 'in one call' phrasing strongly suggests it replaces calling several individual tools, which is clear contextual guidance.

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