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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is covered. The description adds nothing beyond that: no mention of filtering, pagination, time range, or what the history records represent. The duplicated endpoint line consumes space without adding behavioral context.

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 identical sentence appears twice, which is pure redundancy. The remaining clause is useful but the content is not front-loaded with any purpose or scope statement.

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?

A list/history endpoint with no output schema, 0% parameter documentation, and nested free-form query objects requires the description to explain what is returned and how to filter. Instead it offers a pointer to describe_operation, leaving the agent to make a second call just to learn the request shape.

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 coverage is 0% for 2 parameters (a free-form 'query' object and an empty 'params' object), so the description must compensate. It only says describe_operation has the native request schemas, which defers the work rather than documenting accepted query keys or formats.

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 the raw path 'GET /api/import/history' repeated twice, which essentially restates the tool name rather than explaining what the history covers (imports? batches? field changes?). An agent cannot distinguish it from siblings like get_pending_imports, get_import_status_by_importId, or get_bulk_imports based on this text.

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 statement of when to use this tool versus the many sibling import tools. The only actionable hint is that describe_operation provides native request schemas, which is a pointer for schema discovery, not usage guidance or exclusions.

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