get_journal_register

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

The description indicates a read-only 'get' operation, consistent with the readOnlyHint annotation. It adds that the output is a month-by-month summary, providing some behavioral detail beyond the annotation, though it does not mention potential side effects (which are none for a get).

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 sentence that efficiently conveys the tool's purpose, output format, and design reference. It is well-structured and contains no extraneous information.

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?

For a read-only retrieval tool with two parameters, the description is complete: it explains what it returns (month-by-month summary) and the date range context. It does not specify the exact response schema, but that is not necessary given the simplicity and the explicit mention of similarity to get_sales_register.

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 input schema fully documents 'from' and 'to' as date strings with explicitly stated format. The description reinforces that these form a date range for the register, enhancing understanding of how the parameters are used beyond the schema's basic descriptions.

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 tool retrieves the Journal Register from TallyPrime for a date range, with a month-by-month summary of Journal voucher activity. It distinguishes itself from other register tools by naming the specific voucher type and referencing the similar get_sales_register design.

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 implies when to use this tool (for journal voucher activity) and references a sibling tool for design context, but it does not explicitly contrast with alternatives like get_purchase_register. However, the purpose is clear enough that an agent can select it appropriately.

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