Criar transação recorrente

create_recurring_transaction

Cria uma regra recorrente e, de uma vez, já gera todas as transações concretas entre startDate e endDate (default endDate: 1 ano após startDate) — as datadas até hoje entram como pagas e afetam o saldo da conta imediatamente; as futuras entram como pendentes. Se cardId for informado, também cria/vincula as faturas de cartão correspondentes a cada ocorrência EXPENSE. Diferente de Transaction, RecurringTransaction não tem categoryId (FK) — category é só um rótulo texto livre.

A4.7/5.0

Behavior5/5

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

Annotations are all false, so the description carries the full burden for behavioral disclosure. It reveals that past-dated occurrences become paid and immediately affect balance, future ones are pending, and card invoices are created for EXPENSE occurrences when cardId is supplied — exactly the non-obvious side effects an agent needs to know.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three dense sentences with no filler: the core behavior, default endDate, payment status split, card invoice behavior, and the categoryId contrast are each presented once and all earn their place. Key information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema available, return-value explanation is unnecessary. The description covers the non-obvious behaviors (immediate balance impact, pending future occurrences, card invoice creation, category free-text semantics) and leaves field mechanics to the fully described schema, making it complete for a 12-parameter create tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds value by explaining the temporal consequence of startDate/endDate (past occurrences paid, future pending) and reinforcing the cardId invoice behavior beyond the raw field descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Cria uma regra recorrente e, de uma vez, já gera todas as transações concretas entre startDate e endDate') and explicitly distinguishes RecurringTransaction from Transaction by noting the absence of categoryId. This makes the tool's purpose unambiguous and separable from sibling create_transaction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear context for when to use the tool and directly contrasts with Transaction, signaling that if a real category FK is needed, the one-off Transaction tool is the alternative. It does not explicitly enumerate all when-not scenarios, but the distinction is enough to route an agent correctly.

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