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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description adds nothing beyond that: no pagination behavior, no ordering of versions, no note on what happens if the setup id doesn't exist, and no return shape.

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 short but padded: the identical endpoint path is printed twice, and the second copy carries no new information. The only substantive sentence is a pointer to describe_operation, so the space is not well spent.

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 exists and nothing in the description explains what the versions list contains or how it is shaped, which matters for a nested-object tool. Combined with an undocumented query parameter, an agent has to fall back on describe_operation for anything beyond the raw URL.

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%, so the description must compensate and it does not. The ':id' is only visible as a URL placeholder with no statement that it is the journal-close setup identifier, and the free-form 'query' object parameter is entirely unaddressed in the description.

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 restates the endpoint path 'GET /api/accounting/journal-close/setups/:id/versions', which does convey a verb (retrieve) and resource (versions of a journal-close setup). However, it never explains in plain language what a 'version' is here, and it does nothing to distinguish this from the many other journal-close siblings such as get_accounting_journal_close_profiles_* or get_accounting_journal_close_runs_by_id_*.

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 alternatives. The only pointer is 'describe_operation provides native request schemas', which redirects to a schema helper rather than explaining selection criteria. No prerequisites, no exclusions.

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