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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description's only behavioral addition is 'Paged', which is also fully documented in the schema's page/page_size descriptions, leaving no extra context about ordering, filtering, or what a page contains.

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?

Three short fragments with zero filler, and the resource qualifier is front-loaded. It is efficient, though the telegraphic style leaves no room for any of the missing guidance.

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 no output schema, the description should convey what a journal entry record looks like or at least note there is no filtering support. It says neither, leaving an agent to guess whether entries can be narrowed by date, account, or period.

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% — both page (1-based, use next_page) and page_size (1-100) are well documented in the schema. The description adds nothing about parameters, so the baseline of 3 applies.

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 identifies the resource as 'Manual journal entries (general journal)', which usefully narrows scope beyond the bare title, but it contains no verb of its own — the listing action is only implied by the tool name. It does implicitly distinguish itself from jurnal_get_journal_entry, but the differentiation is never made explicit.

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?

There is no guidance on when to call this versus jurnal_get_journal_entry, jurnal_get_general_ledger, or jurnal_get_trial_balance, all of which touch similar accounting data. 'GET /journal_entries' is an implementation detail, not a usage condition.

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