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

With no annotations, the description carries the full burden. It discloses that the tool lists missing/out-of-date items and orders them by severity. The verb 'List' implies a read operation, and the criteria + sort order are valuable behavioral details. It doesn't explicitly state read-only or describe pagination, but for a zero-parameter list tool this is adequate.

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 description is a single, focused sentence. It front-loads the verb and resource, adds a clarifying example of what constitutes a finding, and ends with the sort order. Every word earns its place with no redundancy.

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 zero-parameter, no-output-schema tool, the description is nearly complete. It explains what is listed, the inclusion criteria, the regulatory context, and the ordering. It might benefit from examples or definitions of 'out of date', but the current description is sufficient for an agent to understand the tool's purpose and invoke it successfully.

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?

There are 0 parameters, so the baseline is 4. The description adds no parameter-specific semantics, but none are needed. The empty schema confirms no parameters exist, and the description's scope definition effectively covers the input space.

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 uses a specific verb ('List') and resource ('driver qualification file items'), and clearly defines the scope: items that are missing or out of date, which would be findings in a DOT compliance review. It also states the sort order ('Most serious first'), fully distinguishing it from sibling tools like get_items_due or search_dq_items.

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 description gives clear context for when to use this tool: to identify driver qualification file issues that would constitute DOT compliance review findings. Though it doesn't name alternative tools or explicitly exclusions, the context is specific enough for an agent to select it over siblings for audit-risk listing.

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