context-manager（上下文管理器）

Context Manager

Purpose

Provides expertise in AI context management, memory architectures, and context window optimization. Handles conversation history, RAG memory systems, and efficient context utilization for LLM applications.

When to Use

• Designing AI memory and context systems
• Optimizing context window usage
• Implementing conversation history management
• Building long-term memory for AI agents
• Managing RAG retrieval context
• Reducing token usage while preserving quality
• Designing multi-session memory persistence

Quick Start

Invoke this skill when:

• Designing AI memory and context systems
• Optimizing context window usage
• Implementing conversation history management
• Building long-term memory for AI agents
• Reducing token usage while preserving quality

Do NOT invoke when:

• Building full RAG pipelines (use ai-engineer)
• Managing vector databases (use data-engineer)
• Coordinating multiple agents (use agent-organizer)
• Training embedding models (use ml-engineer)

Decision Framework

Memory Type Selection:
├── Single conversation → Sliding window context
├── Multi-session user → Persistent memory store
├── Knowledge-heavy → RAG with vector DB
├── Task-oriented → Working memory + tool results
└── Long-running agent
    ├── Episodic memory → Event summaries
    ├── Semantic memory → Knowledge graph
    └── Procedural memory → Learned patterns

Core Workflows

1. Context Window Optimization

1. Measure current token usage
2. Identify redundant or verbose content
3. Implement summarization for old messages
4. Prioritize recent and relevant context
5. Use compression techniques
6. Monitor quality vs. token tradeoff

2. Conversation Memory Design

1. Define memory retention requirements
2. Choose storage strategy (in-memory, DB)
3. Implement message windowing
4. Add summarization for overflow
5. Design retrieval for relevant history
6. Handle session boundaries

3. Long-term Memory Implementation

1. Define memory types needed
2. Design memory storage schema
3. Implement memory write triggers
4. Build retrieval mechanisms
5. Add memory consolidation
6. Implement forgetting policies

Best Practices

• Summarize old context rather than truncating
• Use semantic search for relevant history retrieval
• Separate system instructions from conversation
• Cache frequently accessed context
• Monitor context utilization metrics
• Implement graceful degradation at limits
