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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that (no pagination, filter semantics, or authentication context), so it contributes no behavioral value.

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 single repeated sentence is redundant waste, and the operation-ID/metadata boilerplate is not front-loaded with any useful information. Brevity here reflects under-specification rather than efficiency.

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?

For a tool with no output schema, 0% parameter documentation, and nested-object inputs, the description provides no guidance on filtering, pagination, or response shape. It is wholly inadequate for calling the tool correctly.

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?

There are two parameters (query, params) with 0% schema description coverage and nested objects, yet the description says nothing about what may be passed in query or params. It entirely fails to compensate for the schema gap.

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 only restates the tool title/path twice ("GET /api/accounting/journal-close/batches") without saying what a "journal close batch" is or what listing them returns. With many sibling journal-close tools (runs, profiles, setups, catalog), an agent cannot distinguish this tool from them based on the description.

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 that "describe_operation provides native request schemas," which points to a meta tool rather than explaining when to use this endpoint vs. siblings like get_accounting_journal_close_runs or get_accounting_journal_close_catalog. No when-to-use, no exclusions.

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