Create transaction

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 states the write-profile requirement but omits side effects, validation behavior, or consequences of creating a transaction (e.g., balance updates, duplicate handling). This is insufficient for a mutation tool.

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 that immediately states the action and object. It is concise and wastes no words, though it sacrifices completeness for brevity.

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?

The tool has 13 parameters, required fields, nested objects, and no output schema, yet the description covers only the basic purpose and a vague permission note. It does not guide the agent on required inputs, the relationship between source and destination amounts, or the expected response. The description is grossly inadequate for the tool's complexity.

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 explain any of the 13 parameters. It merely echoes the type enum from the schema. The description adds no meaning beyond the structured schema, which is especially damaging given the complex nested objects and amount patterns.

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 uses the specific verb 'Create' with the resource 'transaction' and explicitly lists the four transaction types (income, expense, transfer, balance modification), which clearly distinguishes it from sibling tools like patch_transaction or delete_transaction.

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 does not provide explicit guidance on when to use this tool versus alternatives such as patch_transaction or apply_transaction_batch. It only mentions 'Requires standard write profile,' which is a permission note, not usage context or exclusions.

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