Record Multiple Transactions

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

No annotations are present, so the description carries the full burden. It discloses that the tool will 'categorize them all', which is a behavioral trait beyond the schema. However, it does not mention potential failure modes, validation constraints, or whether records are appended or overwritten. For a bulk write operation, this is a moderate disclosure.

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 two sentences, front-loaded with the purpose, and every sentence provides value. The first sentence states the action, the second gives use cases and hints at behavior. No fluff.

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 is a bulk write with no output schema, the description is reasonably complete. It explains the core action, appropriate use cases, and the categorization behavior. It doesn't need to detail return values since no output schema exists, and the input schema is fully self-explanatory.

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 schema description coverage is 100%, with all properties documented including nested item fields. The description says 'Give me a list' which aligns with the 'transactions' array parameter but adds no further semantics. Since the schema already fully describes parameters, baseline 3 is appropriate.

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 the tool records multiple transactions at once, which is a specific verb and resource. It clearly distinguishes from the sibling tool 'record_transaction' by emphasizing 'multiple at once', and from import tools by describing a direct list input rather than file-based import.

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 gives clear use cases: 'great for entering a batch of receipts or a month's worth of bank statement entries.' This provides context for when to use the tool. It doesn't explicitly contrast with alternatives like 'import_csv' or 'record_transaction', but the 'multiple at once' positioning is implicit differentiation.

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