Agent Context Preservation and Recovery(ACP)

Systematic preservation and recovery of agent conversation context, memory state, and reasoning chains during failures

Complexity: mediumFault Tolerance Infrastructure

🎯 30-Second Overview

Pattern: Systematic preservation and recovery of agent conversation context, memory state, and reasoning chains

Why: Enables seamless conversation continuity across failures, 73% reduction in redundant computations, 89% improvement in context relevance

Key Insight: Hierarchical memory (STM/LTM/semantic) + vector search + secure context sharing = persistent agent intelligence

⚡ Quick Implementation

1Define Memory:Establish memory hierarchy (STM, LTM, semantic)
2Implement Storage:Vector DB + knowledge graph for context
3Context Snapshots:Capture conversation state at checkpoints
4Recovery Logic:Rebuild agent state from stored context
5Validate Continuity:Ensure seamless conversation flow
Example: conversation_state → memory_snapshot → failure_recovery → context_reconstruction → seamless_continuation

📋 Do's & Don'ts

✅Use hierarchical memory (short-term, long-term, semantic)
✅Implement vector-based semantic search for context discovery
✅Cache conversation state with TTL based on importance
✅Use knowledge graphs for temporal and multi-hop reasoning
✅Implement secure access controls (SAMEP protocol)
❌Store all conversation history without pruning strategies
❌Ignore semantic validation during context reconstruction
❌Mix episodic and semantic memory without clear boundaries
❌Skip encryption for sensitive conversation context
❌Assume all past context is equally relevant for recovery

🚦 When to Use

Use When
