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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is covered. The description adds essentially nothing beyond a pointer to describe_operation, giving no information about error behavior, what a baseline represents, or response 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 single sentence is duplicated verbatim, wasting half the text, and the remaining operation-ID/describe_operation note is boilerplate. No front-loaded explanation of the tool's effect.

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 0% schema coverage, no output schema, and a nested query object, the description is far too thin to let an agent call this correctly. Nothing explains what 'baseline' data is or what the untyped query parameters do.

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% for both parameters, so the description would need to explain 'id' and the free-form 'query' object. It only implicitly shows ':id' in the path, leaving the query object and id format/constraints (maxLength 2000, string) 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 only repeats the endpoint path 'GET /api/accounting/journal-close/profiles/:id/baseline' twice, with no natural-language explanation of what a 'baseline' profile is or what is returned. The path does imply a read of a baseline resource scoped to an id, but it adds nothing the title doesn't already state and gives no way to distinguish this tool from the many sibling get_accounting_journal_close_profiles_b_* variants.

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 when-to-use guidance, no mention of alternatives such as describe_operation or the sibling profile tools, and no prerequisites. The agent is left to infer usage entirely from the URL.

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