Agent Context Manager

Intelligent context management for AI agents with cost optimization.

Problem

AI agents have limited context windows (e.g., 128k tokens) but often generate or process more content than fits. Existing solutions:

• Claude Code /compact: Loses important information, black box operation
• Gemini long context: Expensive (price doubles after 200k tokens), vendor-locked
• Simple truncation: Discards potentially critical information

Solution

agent-context-manager provides intelligent, transparent context management:

1. Semantic compression: Understands content importance, not just truncation
2. Priority-based retention: Keeps critical information based on task importance
3. Cost optimization: Integrates with Budget Guard for cost-aware decisions
4. Transparent operation: Developers control what gets kept/discarded
5. Vendor-agnostic: Works with any LLM/framework

Features

• Context monitoring: Real-time token usage tracking
• Intelligent compression: Semantic understanding of content importance
• Priority management: Mark messages as high/medium/low priority
• Cost integration: Works with Budget Guard for cost optimization
• Visual dashboard: Context usage analytics and optimization insights
• Multi-model support: OpenAI, Anthropic, Google, and open-source models

Installation

pip install agent-context-manager

For LLM-powered semantic compression (optional):

pip install agent-context-manager[llm]

Quick Start

from agent_context_manager import ContextManager

# Initialize with your model and budget
manager = ContextManager(
    model="gpt-4",
    max_tokens=128000,
    budget_guard_api_key="your-api-key"  # Optional, for cost optimization
)

# Add messages with priorities
manager.add_message(
    content="System instructions are critical",
    role="system",
    priority="high"
)

manager.add_message(
    content="Recent conversation is important",
    role="user",
    priority="medium"
)

manager.add_message(
    content="Historical data can be compressed",
    role="assistant",
    priority="low"
)

# Get optimized context (automatically compresses if needed)
optimized_context = manager.get_optimized_context()

# Monitor usage
stats = manager.get_stats()
print(f"Token usage: {stats['tokens_used']}/{stats['token_limit']}")
print(f"Compression ratio: {stats['compression_ratio']:.1%}")
print(f"Cost savings: ${stats['cost_savings']:.4f}")

CLI Usage

# Monitor current context usage
agent-context-manager monitor

# Analyze and optimize a conversation file
agent-context-manager optimize conversation.json --output optimized.json

# Generate optimization report
agent-context-manager report --days 7

Integration with AI Agent Monitoring Suite

agent-context-manager is part of the AI Agent Monitoring Suite:

• Budget Guard: Cost tracking and optimization
• Agent Watchdog: Execution monitoring and circuit breaking
• Memory Consolidation: Learning from agent memory logs
• Task Manager: Task switching and time tracking
• Context Manager: Intelligent context optimization (this package)

Use Cases

1. Long-running AI agents: Manage context across days/weeks of operation
2. Cost-sensitive applications: Optimize token usage to reduce costs
3. Complex workflows: Preserve critical information across task switches
4. Multi-agent systems: Coordinate context across multiple agents
5. Development/debugging: Understand what information agents are using

How It Works

1. Monitor: Tracks token usage in real-time
2. Analyze: Identifies important vs redundant information
3. Prioritize: Marks content based on role, recency, and keywords
4. Compress: Applies intelligent compression when needed
5. Optimize: Balances context quality vs cost
6. Report: Provides insights and recommendations

Configuration

manager = ContextManager(
    model="gpt-4",                    # LLM model name
    max_tokens=128000,                # Context window size
    compression_threshold=0.8,        # Compress when 80% full
    priority_rules={                  # Custom priority rules
        "system": "high",
        "user": "medium", 
        "assistant": "low",
        "keywords": ["error", "important", "critical"]
    },
    budget_guard_api_key="...",       # Optional cost integration
    enable_semantic_compression=True  # Use LLM for better compression
)

Performance

• Token reduction: 30-50% typical reduction without losing critical information
• Cost savings: 20-40% reduction in token costs
• Quality preservation: Maintains task completion rates while reducing context
