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

Annotations already declare readOnly, idempotent, non-destructive and closed-world behavior, so the safety profile is covered. The description adds genuinely new context, the seven-day retention window and the requirement that the job be owned and completed, but says nothing about what happens on expiry or on an unowned/incomplete job.

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 dense sentence with no filler, and the resource is front-loaded before the qualifying conditions. Slightly compressed phrasing ('complete-file validation report') costs a little readability but no waste.

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 one-parameter read tool with no output schema this covers the core purpose, but it leaves the failure modes (expired retention, incomplete or unowned job) and the report's shape unexplained, which an agent needs to handle results 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?

With 0% schema description coverage, the description carries the burden for job_id, and it only indirectly conveys that the id must refer to an owned, completed job still inside retention. It adds no format or sourcing detail for the identifier.

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?

States a specific verb (Read) and a specific resource (complete-file validation report), plus scoping conditions (owned completed job, seven-day retention). It separates the tool from write siblings like start_supplier_import, though it does not explicitly distinguish it from get_supplier_import or get_supplier_import_output.

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 preconditions 'owned', 'completed' and 'seven-day retention' imply when the call is valid, but there is no explicit when-to-use or when-not-to-use guidance and no named alternative for retrieving import data or output instead of the validation report.

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