Phase 4: Advanced Cognitive Capabilities

4.1 Sophisticated Grammar Systems

Objectives

• Expand cognitive grammar beyond basic GBNF
• Implement context-sensitive grammar parsing
• Create grammar evolution and learning

Actionable Steps

Week 1-2: Advanced Grammar Parser

• Extend GBNF with context sensitivity
• Implement grammar composition and inheritance
• Add dynamic grammar modification
• Create grammar optimization algorithms

Week 3-4: Grammar Learning

• Implement grammar induction from examples
• Add grammar evolution through usage patterns
• Create grammar sharing between agents
• Add grammar validation and testing

Success Criteria

• Context-sensitive parsing for complex cognitive expressions
• Grammar learning from agent interactions
• Grammar sharing improves communication efficiency
• Grammar evolution creates more expressive cognitive languages

4.2 Multi-Modal Cognitive Processing

Objectives

• Integrate text, image, and audio processing
• Create cross-modal reasoning capabilities
• Enable multi-modal agent communication

Actionable Steps

Week 5-6: Multi-Modal Foundation

• Integrate whisper.cpp for audio processing
• Add image processing using ggml vision models
• Create unified multi-modal tensor representations
• Implement cross-modal attention mechanisms

Week 7-8: Cross-Modal Reasoning

• Add multi-modal pattern matching
• Implement cross-modal analogical reasoning
• Create multi-modal memory integration
• Add multi-modal cognitive grammar extensions

Success Criteria

• Processing of text, audio, and visual inputs
• Cross-modal reasoning and analogy detection
• Multi-modal communication between agents
• Unified cognitive processing across modalities
