get_coverage_status_by_serial

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

With no annotations, the description should fully convey behavior. It only restates the capacity constraint (up to 75 serials) already present in the schema and lists output fields, but omits safety aspects, error handling, or read-only semantics.

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?

Two concise sentences with no redundant words. Front-loaded with action and capacity, then lists return contents. Every sentence earns its place.

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?

Given high schema coverage and only two parameters, the description is adequate but lacks usage guidelines and behavioral details. The output specification is partial but reasonable for a coverage-status tool.

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 100% with good descriptions for both parameters. The description adds minimal value beyond the schema, only reinforcing the max 75 serial numbers. Baseline 3 applies.

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 clearly states the tool retrieves detailed coverage status, warranty, and product information for up to 75 serial numbers. It distinguishes itself from the sibling 'get_coverage_summary_by_serial' by implying it returns more comprehensive data, though not explicitly.

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 provides no guidance on when to use this tool versus alternatives like get_coverage_summary_by_serial, nor does it mention any prerequisites or context-specific conditions.

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