get_trial_balance

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

With no annotations, the description must carry the full burden of behavioral disclosure. It mentions a limitation (no department/location breakdown) but does not describe the return format, data freshness, or other behavioral aspects. The description adds some value but lacks comprehensive 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 highly concise with two sentences and a note, all front-loaded with essential information. No redundancy or wasted words.

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 the simple schema (3 string parameters, no enums, no output schema), the description is fairly complete. It covers use cases and a key limitation. However, it could mention default behavior for empty dates or result handling to be fully comprehensive.

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?

All three parameters (start_date, end_date, accounting_method) have clear descriptions in the input schema. The tool description adds no additional meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 'Get a Trial Balance report' and provides context about its usefulness for month-end close and reconciliation. However, it does not explicitly distinguish this tool from sibling report tools like get_balance_sheet or get_profit_loss, which share similar use cases.

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 specifies when to use the tool ('month-end close and reconciliation') and includes an important limitation (no department/location breakdown in QuickBooks Online). While it gives good context, it lacks explicit guidance on when not to use it or alternative tools.

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