brc_create_nominal_journal_batch

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

No annotations are provided, so the description carries full burden. It discloses the creation action and the need for user confirmation, but does not specify permissions, side effects, or success response. The warning about confirmWrite is good, but more behavioral context (e.g., whether it automatically validates balance, if it can be undone) would improve transparency.

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 with two sentences. The first sentence states the primary purpose, and the second adds critical usage guidance. No wasted words, and the structure is optimal for quick comprehension.

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 no output schema, the description should hint at return values or status. It does not explain what the response contains (e.g., batch ID). While the schema documents the parameters, the description lacks completeness regarding the result of the operation. The balance and confirmation advice are helpful, but overall it could be more comprehensive for a complex creation tool.

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%, so baseline is 3. The description adds meaning beyond schema by stating that debit and credit lines must balance and that confirmWrite should only be true after user confirmation. This extra context for the parameters (especially confirmWrite and accountTransactions) elevates the score.

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 'Creates a new Nominal Journal Batch' with a specific verb and resource, distinguishing it from siblings like update, delete, or list. It also adds essential constraints about balanced lines and confirmation flow.

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 provides explicit usage guidance: not to set confirmWrite=true until user confirms, and that journal lines must balance. It implies a two-step creation process. However, it does not compare this tool to potential alternatives for obtaining the same result, though the sibling set makes the purpose clear.

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