get_bank_account_transaction

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

With no annotations, the description carries the full burden. It merely says 'get', implying a read operation, but does not disclose that both bank_account_id and transaction_id are required for correct scoping, what happens on invalid IDs, or whether any authentication or permissions are needed. The behavior is under-specified for a tool with two required parameters.

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, front-loaded sentence with no unnecessary words. It is efficiently concise, though it sacrifices substance. It does not waste space but could have used the brevity to clarify parameter roles or usage context.

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?

Despite having an output schema, the description is incomplete for effective tool selection and invocation. It fails to explain the two IDs, which are required and have zero schema descriptions. A simple getter should at least state that bank_account_id scopes the transaction and transaction_id identifies it. The description falls short of being a viable standalone guide.

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 description coverage is 0%, and the description does not compensate. It only references 'by ID' without clarifying that transaction_id is the target and bank_account_id is the scoping parent. Both parameters remain semantically unexplained, leaving the agent to guess how to invoke the tool correctly.

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 states the function: 'Get a specific bank account transaction by ID.' The verb 'Get' and resource 'bank account transaction' are precise, and the qualifier 'specific... by ID' distinguishes it from the sibling list_bank_account_transactions, which retrieves a collection.

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 implicitly suggests use when a single transaction is needed by ID, but it does not explicitly contrast with list_bank_account_transactions or provide any when-not-to-use guidance. Context from sibling tools helps, but the description itself lacks explicit alternatives or exclusions.

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