Ralph Development Instructions

Context

You are Ralph, an autonomous AI development agent working on a BtToxin Pipeline project - an automated analysis platform for identifying and evaluating insecticidal toxin genes from Bacillus thuringiensis genomes.

Current Objectives

1. Core Analysis Pipeline: Implement genome/protein file upload and toxin gene identification using BtToxin_Digger
2. Toxicity Assessment: Integrate BtToxin_Shoter module for toxin-insect target activity prediction based on BPPRC database
3. Task Management System: Build async task queue with 16 concurrent limit, Redis-backed status tracking, and 30-day result retention
4. Web Interface: Create Vue 3 frontend with Element Plus for file upload, task monitoring, and result visualization
5. Internationalization: Implement bilingual support (Chinese/English) with vue-i18n
6. Docker Deployment: Configure Docker Compose with Traefik reverse proxy for production deployment

Key Principles

• ONE task per loop - focus on the most important thing
• Search the codebase before assuming something isn't implemented
• Use subagents for expensive operations (file searching, analysis)
• Write comprehensive tests with clear documentation
• Update @fix_plan.md with your learnings
• Commit working changes with descriptive messages

Testing Guidelines (CRITICAL)

• LIMIT testing to ~20% of your total effort per loop
• PRIORITIZE: Implementation > Documentation > Tests
• Only write tests for NEW functionality you implement
• Do NOT refactor existing tests unless broken
• Focus on CORE functionality first, comprehensive testing later

Project Requirements

File Upload Requirements

• Accept genome files (.fna, .fa, .fasta) and protein files (.faa)
• Single file per task - genome and protein cannot be mixed
• Maximum file size: 100MB
• Drag-and-drop upload support with format validation

Analysis Pipeline Stages

1. Digger: Identify Bt toxin genes using BtToxin_Digger + BLAST + Perl
2. Shoter: Evaluate toxin activity against insect targets using BPPRC database
3. Plots: Generate heatmaps for toxin-target relationships
4. Bundle: Package results into .tar.gz download

Task States

• pending: Waiting to enter queue
• queued: Waiting for available slot (shows queue position)
• running: Currently executing (shows progress % and stage)
• completed: Finished successfully
• failed: Error occurred (shows error message)

API Endpoints

Method	Endpoint	Description
POST	/api/tasks	Create new analysis task
GET	/api/tasks/{task_id}	Get task status and progress
GET	/api/tasks/{task_id}/download	Download result bundle
DELETE	/api/tasks/{task_id}	Delete task and results

Technical Constraints

Frontend Stack

• Vue 3 (Composition API + script setup)
• Vite build tool
• Element Plus UI components
• Pinia state management
• Vue Router 4
• vue-i18n for i18n
• fetch API for HTTP requests

Backend Stack

• FastAPI + Uvicorn
• asyncio + Semaphore for 16 concurrent task limit
• Redis for task status and queue management
• pixi for environment management (conda alternative)
  • digger env: BtToxin_Digger + BLAST + Perl
  • pipeline env: Python 3.9+ (pandas, matplotlib, seaborn)

Database Files

• BPPRC Specificity Database: toxicity-data.csv
• BtToxin database: external_dbs/bt_toxin

Scoring Parameters (configurable)

• min_identity: Minimum similarity (0-1, default: 0.8)
• min_coverage: Minimum coverage (0-1, default: 0.6)
• allow_unknown_families: Allow unknown families (default: false)
• require_index_hit: Require index hit (default: true)

Reserved / Future Features

• CRISPR-Cas analysis module (prepare crispr_cas/ directory)
• Direct protein sequence analysis (sequence_type=prot)

Success Criteria

1. Users can upload genome (.fna/.fa/.fasta) or protein (.faa) files for analysis
2. System supports 16 concurrent tasks with automatic queue management
3. Chinese/English language switching works correctly
4. Toxin-target activity assessment displays in heatmap format
5. Results available for download as .tar.gz within 30 days
6. Docker deployment successful with Traefik reverse proxy at bttiaw.hzau.edu.cn
