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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It hints at aggregation via '累計' (cumulative) but does not disclose the return format, whether date parameters are effectively required despite having zero required parameters, how date ranges are interpreted, or how tax/sub-account flags affect results.

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 single Japanese sentence is efficient and front-loaded with the core purpose, with no wasted words. However, it borders on under-specification rather than deliberate concision, since critical usage and parameter details are entirely absent.

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 8 undocumented parameters, no output schema, and no annotations, the description is far from complete. It explains none of the parameters, date constraints, return values, or which offices/contexts it applies to, leaving an agent unable to construct a correct call with confidence.

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 only 25%, with just start_month and end_month documented as 'calendar month.' The description adds nothing about the 8 parameters (end_date, end_month, start_date, fiscal_year, include_tax, start_month, journal_types, with_sub_accounts). With such low coverage, the description was expected to compensate but does not.

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 a specific verb ('取得' = retrieve) and resource ('損益計算書の試算表（累計）' = cumulative trial balance of the profit and loss statement), and the '累計' (cumulative) qualifier partially distinguishes it from the transition-oriented siblings. However, it does not explicitly differentiate from the balance-sheet or transition variants by explaining what 'trial balance' means as a report type.

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 offers no guidance on when to use this tool versus the sibling report tools (mfc_ca_getReportsTrialBalanceBalanceSheet, mfc_ca_getReportsTransitionProfitLoss, etc.). There is no context about choosing trial-balance vs transition variants, no prerequisites, and no exclusions.

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