Instructions

Barcode Scanner. Free online barcode and QR code scanner. Read UPC, EAN, Code 128, Code 39, QR, Data Matrix, Aztec, PDF417 and more from your camera or an image file. Auto-detects the code, or drag a box to scan a region.

Behavior4/5

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

No annotations exist beyond the title, so the description carries the full burden. It discloses that the tool reads barcodes from camera or image, auto-detects, or allows region selection. It is a read-only operation with no destructive behavior. It could mention privacy (e.g., not storing images) but 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences front-load the purpose and provide key details (supported formats, input methods, features). No unnecessary information; each sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description lacks information about the output format (e.g., decoded text, raw data). Given no output schema, this gap is notable. It also does not mention the sibling 'osint_barcode_generator' for contrast. However, for a simple scanner, the core purpose is clear.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0 defined parameters (additionalProperties: true), so schema coverage is 100%. The description implicitly defines the input (camera or file) without formal parameters. Since no parameters are needed, the description adds sufficient meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it is a barcode and QR code scanner, lists many supported formats (UPC, EAN, Code 128, etc.), and indicates it works from camera or image file. This distinguishes it from the sibling 'osint_barcode_generator' which generates barcodes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains the input methods (camera or image file) and provides guidance on auto-detection or manual region selection. However, it does not explicitly state when not to use this tool or compare it with alternatives like 'osint_qr_code_generator' or other scanners.

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