Transactions Create Transaction

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

Annotations indicate readOnlyHint=false, destructiveHint=false, idempotentHint=false. The description adds 'may create or update' but doesn't clarify side effects like balance updates, authorization needs, or idempotency. Beyond annotations, it provides little behavioral context.

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?

Extremely concise (one sentence) but at the expense of usability. Lacks structure and important details like parameter guidance or response format. Every sentence does not earn its place due to under-specification.

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 12 parameters, 5 required, no output schema, and sparse annotations, the description is too brief. It doesn't cover common use cases, return values, or error conditions. Incomplete for a create tool of this 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 has 12 parameters with only 17% description coverage (fields and output_mode have descriptions). The tool description does not explain any parameters, missing the opportunity to clarify common optional fields like notes, goal_id, or should_update_balance. For low coverage, description should compensate but fails.

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 transaction' which is a specific verb+resource. However, it adds ambiguity with 'This may create or update Monarch data.' Since the tool name is create and there is a separate update tool, this could mislead. Still, the primary purpose is clear.

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 vs. alternatives like update_transaction. No when-not-to-use or prerequisites provided. The description is too minimal to guide selection.

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