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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered by structured data. The description adds nothing about what settings are returned, scope (company vs workspace), or auth requirements beyond pointing to describe_operation.

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?

Short, but the path is duplicated verbatim and the operation ID adds no decision value. It is under-informative rather than concise.

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 2 undocumented parameters, 0% schema coverage, and no output schema, the description should explain request shape and return content. It only defers to describe_operation, leaving real gaps for an agent that must call it blind.

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 schema is a generic free-form 'query' object plus empty 'params'. The description makes no attempt to explain what those parameters accept, so an agent has no idea which query keys are valid.

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 endpoint path twice: 'GET /api/accounting/journal-close/company-settings.' It names a resource but adds no verb-level explanation of what the endpoint returns, and it is indistinguishable from a dozen sibling journal-close endpoints (company_co, configurat, catalog, setups). This is close to tautology against the title.

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 guidance on when to call this versus the many other journal-close read endpoints. The only directive is 'describe_operation provides native request schemas,' which is a discovery hint, not usage guidance.

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