batch_decode_barcodes

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

The description adds the aggregation behavior of totaling quantities by product number, which is useful beyond the readOnly/idempotent annotations. However, it does not disclose return format, error handling, or behavior with invalid/mixed barcode types. No contradiction with annotations.

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 that conveys the primary purpose and aggregation behavior without excess words or redundancy. It is well-structured for quick understanding.

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?

The description covers the core behavior and aggregation, and annotations provide safety profile. However, with no output schema and a nested request object, additional context about return values or barcode type semantics would improve completeness. Generally adequate for a read-only batch 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 description coverage is 0%, and the description provides no parameter details. The nested 'request' object, 'barcodes' array, and 'barcode_type' enum are left entirely to the schema. Given the low coverage, the description fails to compensate by explaining how to specify barcodes or the meaning of barcode types.

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's action ('Decode a batch'), resource ('DigiKey barcodes'), and outcome ('total received quantities by product number'). It distinguishes itself from the sibling 'decode_barcode' by emphasizing batch processing and aggregation.

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 implies using this tool for batch decoding and totaling, but it does not explicitly explain when to choose it over 'decode_barcode' or other barcode-related tools. No exclusions, conditions, or alternatives are mentioned.

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