Get budgetary control impacts

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

Annotations cover the safety profile (readOnly, idempotent, non-destructive, open world), and the description adds a genuinely distinctive behavioral constraint: it never estimates or derives balances, returning null plus a reason and guidance when Oracle Budgetary Control does not supply figures. This is meaningful context beyond what annotations provide.

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?

Front-loaded with the core action, then usage trigger, then the Important caveat in priority order. Every sentence contributes, though the closing caveat is somewhat lengthy and could be tightened without losing meaning.

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?

An output schema exists, so return values need no explanation. Purpose, trigger conditions, and the key limitation on balance reporting are all covered, leaving nothing an agent needs in order to invoke it 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 coverage is 100% and the schema already documents the identifier options and both boolean toggles, including that balances are never estimated. The description adds no syntax, format, or precedence detail beyond what the schema states, so baseline 3 applies.

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?

States a specific verb and resource (explain budgetary control impact on an Oracle Fusion Payables invoice) and enumerates exactly what is reported: funds check/reservation status, control budgets involved, and which lines/distributions failed and why. This is well differentiated from siblings like get_invoice_holds, which would only surface the hold without the funds-check reasoning.

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?

Gives concrete triggering conditions: when an invoice carries an Insufficient Funds or Funds Check Failure hold, or before promising a payment date on a budget-controlled invoice. It does not explicitly name an alternative tool or state when not to use it, so it stops short of a 5.

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