Build the application

## Build
Translate single-language merchant inventory sheets into multilingual Beckn catalog payloads. Verify required schema extensions for retail categories across regional languages.

## User
E-commerce onboarding field agent

## Workflow
1. Receive raw catalog spreadsheets in English or Hindi from local retail merchants.
2. Generate compliant product names, search tags, and descriptions across three target languages.
3. Map product attributes to ONDC retail category taxonomy and packaging rules.
4. Output validated Beckn catalog JSON objects for seller gateway synchronization.

## Interface
Multi-column catalog translator and schema validator highlighting untranslated idioms and missing fields.

## Data
Synthesize typical kirana inventory price sheets covering consumer goods, snacks, and household essentials.
Starter examples below are synthetic. They are not downloaded records.

## Source
[ONDC protocol specifications](https://raw.githubusercontent.com/ONDC-Official/ONDC-Protocol-Specs/master/README.md)
Employs ONDC protocol specifications for retail domain schemas and taxonomy classifications.

## Tools
dspy, pydantic.
DSPy compiles few-shot prompt modules to maintain consistent product taxonomy mappings across multiple languages.
Multilingual model supporting English, Hindi, and regional Indic language generation.

## Deliverables
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

## Acceptance
- Outputs valid Beckn catalog items with language-specific descriptor objects.
- Validates standard pricing structures with proper decimal currency representation.
- Prevents literal translations that alter brand names or technical unit measurements.

      "price_inr": -50,
      "target_langs": [
        "hi"
      ]
    },
    "expected_output": {
      "catalog_entry": null,
      "schema_valid": false,
      "validation_errors": [
        "INVALID_PRICE_VALUE"
      ]
    }
  }
]
```

## Safety
Processes synthetic retail inventories only; executes no real catalog publishing or live network broadcasts.
Use mock external writes. Require human review before any real deployment.
