Backend Development Plan

1. Category-Based System Instructions

Goal: Support system instructions tailored to specific engineering categories (e.g., mechanical, structural, civil, architectural, electrical, aerospace).
Approach:
- Define a set of system instructions for each category.
- Allowed Categories:
  - mechanical
  - structural
  - civil
  - architectural
  - electrical
  - aerospace
- Store these instructions in a configuration file (e.g., JSON or YAML) or a database.
- Update API endpoints to accept a category parameter.
- Use the selected category in the generation logic to apply corresponding instructions.
- Provide a fallback to default instructions if the category isn't recognized.

Add category field to relevant request models (e.g., TextGenerateRequest, ImageTextGenerateRequest).
Validate the category against the allowed values.
Pass category to generation utilities to select appropriate instructions.
Logging and Error Handling:
- Log usage statistics for different categories.
- Return clear error messages if an invalid category is provided.

Allow users to define custom categories or instructions.
Add endpoints to list available categories along with their descriptions.
Implement advanced logging and analytics to observe category usage.
Support multi-category or hybrid instructions.
Extend the configuration:
- Provide detailed parameters per category (e.g., style, tone, structural guidelines).
- Create a configuration file to manage these parameters centrally.
Explore caching mechanisms for repeated generation requests per category.
