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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered structurally. The description adds no behavioral context of its own — no note on response shape, pagination, or what a "dimension source" is in this domain.

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 same path sentence appears twice back-to-back, which is pure waste, and the remaining sentence is a metadata pointer rather than substantive content. Nothing is front-loaded to tell an agent what the tool does.

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?

No output schema and zero schema descriptions mean the description must carry the burden, yet it supplies neither purpose detail, module value semantics, nor the structure of the nested query object. An agent cannot confidently invoke this from the definition alone.

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 0% across 2 parameters. The description only echoes ':module' from the path, giving no semantics for allowed module values, and says nothing about the arbitrary free-form 'query' object, leaving both parameters effectively undocumented.

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 is just the endpoint path repeated verbatim twice, plus an operation ID. The path does imply a read of dimension-source values for a given module, but there is no verb-level statement of what the tool returns and no differentiation from the similarly named sibling get_accounting_journal_close_dimension__eaf4ccfadc2e63425b7f3ace.

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?

No statement of when to use this versus the many other journal-close endpoints. The only guidance is "describe_operation provides native request schemas", which points at how to discover the contract, not when this tool is the right call.

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