### Key Architectural Principles
2025-11-23 20:12:09 -03:00
2025-11-24 09:49:25 -03:00
The system adheres to four fundamental design principles that govern its implementation:
2025-11-23 20:12:09 -03:00
2025-11-24 09:49:25 -03:00
1. **Infrastructure Autonomy**: Complete ownership of the technology stack, from persistent storage layers to natural language processing engines. All components operate within your controlled environment, ensuring data sovereignty and regulatory compliance.
2025-11-23 20:12:09 -03:00
2025-11-24 09:49:25 -03:00
2. **Deterministic Bootstrap**: The initialization sequence follows a predictable, idempotent process that guarantees consistent deployment outcomes across heterogeneous environments. Each bootstrap operation validates prerequisites, provisions resources, and verifies operational readiness through comprehensive health checks.
2025-11-21 12:13:48 -03:00
2025-11-24 09:49:25 -03:00
3. **Economic Efficiency**: The platform's architecture optimizes for total cost of ownership (TCO) by leveraging commodity hardware, open-source components, and efficient resource utilization patterns. Operational costs typically achieve 10x reduction compared to equivalent cloud-based solutions at scale.
4. **Privacy by Design**: Data residency, processing, and storage remain exclusively within your infrastructure perimeter. The system implements defense-in-depth security layers, including encryption at rest, transport layer security, and role-based access control (RBAC).

## Creating Your First Bot - Implementation Guide
### Package Structure and Organization
The bot package system implements a convention-over-configuration approach with hierarchical resource organization:
```
templates/
└── my-bot.gbai/ # Package root (mandatory .gbai extension)
├── my-bot.gbdialog/ # Dialog scripts container
│ ├── start.bas # Entry point (required)
│ ├── handlers/ # Event handlers
│ │ ├── welcome.bas # User onboarding
│ │ └── error.bas # Error handling
│ └── tools/ # Custom tools
│ ├── scheduler.bas # Appointment booking
│ └── calculator.bas # Calculations
├── my-bot.gbkb/ # Knowledge base
│ ├── policies/ # Document collection
│ │ ├── hr-manual.pdf # Human resources
│ │ └── it-security.pdf # IT policies
│ └── products/ # Product information
│ ├── catalog.pdf # Product catalog
│ └── pricing.xlsx # Pricing matrix
├── my-bot.gbot/ # Configuration
│ └── config.csv # Bot parameters
├── my-bot.gbtheme/ # Visual customization
│ └── default.css # Style definitions
└── my-bot.gbdrive/ # File storage
└── templates/ # Document templates
```
### Dialog Script Implementation
BASIC dialog scripts orchestrate conversational flows with minimal complexity:
```basic
' start.bas - Primary conversation entry point
' This script executes when users initiate conversation
' Initialize conversation context
SET CONTEXT "greeting_shown" = FALSE
' Load knowledge resources
USE KB "policies" ' HR and IT policy documents
USE KB "products" ' Product catalog and pricing
' Enable tool extensions
USE TOOL "scheduler" ' Appointment booking capability
USE TOOL "calculator" ' Mathematical computations
' Conversation state machine
main_loop:
IF GET CONTEXT "greeting_shown" = FALSE THEN
TALK "Welcome! I'm your intelligent assistant."
TALK "I have access to company policies and product information."
TALK "I can also schedule appointments and perform calculations."
SET CONTEXT "greeting_shown" = TRUE
END IF
TALK "How may I assist you today?"
' Capture user input with intent classification
user_input = HEAR
' The system AI automatically processes the input using:
' - Loaded knowledge bases for information retrieval
' - Enabled tools for action execution
' - Context history for coherent responses
' Continue conversation loop
GOTO main_loop
```
### Knowledge Base Integration
Document collections are automatically indexed for semantic retrieval:
#### Document Processing Pipeline
1. **Ingestion**: Documents are parsed from supported formats (PDF, DOCX, XLSX, TXT, MD)
2. **Chunking**: Content is segmented into semantic units (typically 256-512 tokens)
3. **Embedding**: Each chunk is converted to vector representation using the embedding model
4. **Indexing**: Vectors are inserted into the vector database with metadata
5. **Retrieval**: Semantic search identifies relevant chunks based on query similarity
#### Supported Document Formats
| Format | Extensions | Processing Method | Metadata Extraction |
|--------|------------|------------------|-------------------|
| PDF | .pdf | Apache PDFBox | Title, Author, Creation Date |
| Word | .docx, .doc | Apache POI | Properties, Styles |
| Excel | .xlsx, .xls | Apache POI | Sheets, Named Ranges |
| Text | .txt, .md | Direct | File Properties |
| HTML | .html, .htm | JSoup | Meta Tags, Structure |
| CSV | .csv | Native Parser | Headers, Schema |
### Tool Development
Tools extend bot capabilities with parameterized functions:
```basic
' scheduler.bas - Meeting scheduling tool
PARAM person AS STRING DESCRIPTION "Person to meet"
PARAM date AS DATE DESCRIPTION "Meeting date"
PARAM time AS TIME DESCRIPTION "Meeting time"
PARAM duration AS INTEGER DEFAULT 30 DESCRIPTION "Duration in minutes"
PARAM location AS STRING DEFAULT "Conference Room" DESCRIPTION "Meeting location"
DESCRIPTION "Schedule a meeting with specified parameters"
' Validate scheduling constraints
IF date < TODAY() THEN
TALK "Cannot schedule meetings in the past."
EXIT
END IF
IF time < "08:00" OR time > "18:00" THEN
TALK "Meetings must be scheduled during business hours (8 AM - 6 PM)."
EXIT
END IF
' Check availability (simplified example)
conflicts = FIND "meetings", "date=" + date + " AND time=" + time
IF conflicts.COUNT > 0 THEN
TALK "Time slot unavailable. Suggesting alternatives..."
' AI generates alternative suggestions
EXIT
END IF
' Create meeting record
meeting_id = GENERATE_ID()
SAVE "meetings", meeting_id, person, date, time, duration, location
' Send confirmation
TALK "Meeting scheduled successfully!"
TALK "Details: " + person + " on " + FORMAT(date, "MMMM dd, yyyy")
TALK "Time: " + FORMAT(time, "h:mm a") + " for " + duration + " minutes"
TALK "Location: " + location
' Optional: Send calendar invitation
IF GET BOT MEMORY "send_invites" = TRUE THEN
SEND MAIL person, "Meeting Invitation", "You're invited to a meeting..."
END IF
2025-11-21 12:13:48 -03:00
```
