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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, covering the safety profile. The description adds nothing beyond that—no indication of what the catalog returns, whether it is user-scoped, or any pagination/auth behavior—so it contributes no behavioral context of its own.

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 wastes its length by repeating the identical endpoint string twice and appending an opaque operation ID, while omitting any actual explanatory content. Not under-specified for lack of space, but structurally redundant.

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, 0% schema coverage, and a nested free-form 'query' object, the description should explain what is returned and what query supports. It provides none of that, so an agent cannot confidently invoke this tool without first calling describe_operation.

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% and the two parameters ('query' as a free-form object and an empty 'params' object) are entirely undocumented. The description says nothing about what query keys are accepted or what they filter, leaving the agent with no usable parameter semantics.

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 'GET /api/accounting/journal-close/catalog' repeated twice, which restates the tool name/title rather than explaining what a journal-close catalog is or contains. An agent learns only that this is some GET on a journal-close catalog, with no differentiation from the many sibling journal-close endpoints.

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 only guidance is 'describe_operation provides native request schemas', which tells the agent where to find parameter details but not when to use this endpoint versus siblings like get_accounting_journal_close_configurat_... or get_accounting_journal_close_profiles_.... No when-to-use or exclusion criteria are present.

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