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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds the return content (record count plus per-record outcome), but says nothing about pagination, terminal states, or error reporting, so it adds modest value beyond the structured fields.

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?

A single compact sentence with the resource front-loaded and zero filler. Efficient, though the casual title phrasing carries no additional routing information.

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 read-only status tool with no output schema, the description covers the headline return (count and per-record outcome). It omits what outcome values look like and whether long imports paginate, leaving minor gaps against annotations that already handle the safety profile.

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?

With 50% schema coverage, the artist parameter is documented in the schema while job_id has none. The phrase 'or the one named' partially compensates by implying job_id selects a specific import, but no format or sourcing guidance is given.

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 states a specific resource (catalog import) and what it reports (how many records are in, and each record's outcome), so an agent grasps the intent. It does not explicitly distinguish itself from siblings like preview_catalog_import or import_catalog, keeping it below a 5.

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?

There is no explicit guidance on when to call this versus import_catalog or preview_catalog_import, nor any stated prerequisites. The parenthetical '(or the one named)' hints you can target a specific job, but the agent must infer the workflow context entirely.

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