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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description only adds that it is a period-scoped GET endpoint; there is no mention of volume, pagination, or what a period default of 'today' yields. Adequate but thin for a reporting endpoint.

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?

Two short clauses plus the endpoint path; front-loaded with the resource and scope. The trailing 'GET /general_ledger.' is nearly redundant but harmless.

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?

With zero required parameters, no output schema, and a fully documented schema, the description is serviceable. It leaves the most error-prone behavior (compare_type shortcut vs custom date range) to the schema and says nothing about the response shape, which matters because no output schema exists.

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 description coverage is 100%, so the schema already explains every parameter including the enum. The description's mention of 'ids from jurnal_list_accounts' repeats schema text, and it does not clarify the interplay between compare_type shortcuts and start_date/end_date beyond what the schema says.

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?

States a specific resource (general ledger) with scope (a period, optionally limited to accounts), which is stronger than a title restatement. It does not differentiate itself from related financial reports like jurnal_get_trial_balance or jurnal_get_balance_sheet, so an agent must infer the distinction.

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?

Implies usage by noting the account filter and pointing to jurnal_list_accounts for obtaining ids, which is a useful prerequisite hint. However, it never says when to choose this report over the trial balance or balance sheet, nor any exclusions.

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