Create Transaction

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

Annotations are all false, and the description does not disclose any behavioral traits. It does not mention whether the operation is idempotent, destructive, or requires specific permissions. For a mutation tool, essential details like side effects or return values are omitted.

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 extremely concise (5 words), but this under-specification harms usability. While front-loaded, it fails to provide necessary context, making it insufficient for effective tool selection and invocation.

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?

With 9 parameters, no output schema, and no additional description, the tool lacks completeness. The agent needs more context about the transaction creation process, constraints, and expected outcomes beyond what the schema provides.

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% with each parameter having a description. The description adds no additional meaning beyond the schema; it simply repeats the tool's purpose. Baseline 3 is appropriate because the schema already provides sufficient parameter documentation.

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 'Create a bank transaction', which clearly indicates the action and resource. However, it does not differentiate from other create tools like create_journal or create_sale_invoice, which also involve creating financial records. The verb 'create' and resource 'bank transaction' are specific, but the context suggests it is for bank transactions only, though not explicitly stated.

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?

No guidance on when to use this tool versus alternatives such as create_journal or create_purchase_invoice. The description provides no context about prerequisites, limitations, or scenarios where this tool should be preferred or avoided.

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