Overview

Sage Agent is a self-improving AI system that learns from every interaction. The agent maintains long-term memory, validates responses to prevent hallucinations, and continuously improves its performance through pattern learning and feedback analysis.

Core Capabilities

• Self-Improving AI: Automatically learns from every interaction, tracks mistakes, and improves over time
• Long-Term Memory: Permanently stores all interactions, never forgets, enables instant recall
• No Hallucinations: Validates every response, detects uncertainty indicators, ensures accuracy
• No Duplication: Checks memory before processing, prevents redundant work
• Token Optimization: 30-60% reduction through advanced compression and caching
• Pattern Learning: Learns usage patterns, recommends optimal strategies
• Multi-Provider Support: 12+ LLM providers including OpenAI, Anthropic, DeepSeek, GLM

Key Features

Self-Improvement System

The agent automatically improves with every interaction:

• Automatic Learning: Every query is remembered, validated, and learned from
• Mistake Tracking: Identifies and learns from errors, prevents repetition
• Quality Monitoring: Tracks response quality trends (improving/stable/declining)
• Pattern Recognition: Learns from usage patterns, optimizes strategies
• Feedback Integration: Incorporates user feedback for continuous improvement
• Success Patterns: Identifies what works, applies successful approaches

Long-Term Memory

Never forgets, always learns:

• Permanent Storage: All interactions stored permanently on disk
• Exact Recall: Instant retrieval of previously asked questions (< 1ms)
• Similar Query Learning: Finds and learns from related past interactions
• Pattern Extraction: Automatically extracts and learns patterns from queries
• Conversation Context: Maintains full conversation history
• Learned Insights: Provides insights from accumulated knowledge

Response Validation

Prevents hallucinations and ensures accuracy:

• Hallucination Detection: Identifies uncertainty indicators ("I think", "maybe", "probably")
• Confidence Scoring: Assigns confidence score (0-1) to every response
• Contradiction Detection: Identifies logical contradictions in responses
• Context Validation: Ensures provided context is utilized
• Quality Checks: Validates response length, relevance, and completeness
• Automatic Flagging: Marks low-confidence responses for review

Token Optimization

Advanced strategies for 30-60% savings:

• Advanced Optimizer: 6 optimization strategies (redundancy removal, verbose compression, etc.)
• Adaptive Compression: Learns optimal compression level for each query type
• Smart Caching: LRU cache with TTL, prevents redundant API calls
• Context Prioritization: Intelligently selects most relevant context
• Deduplication: Eliminates redundant information
• Prompt Rewriting: Rewrites prompts for clarity and brevity

Intelligence Engine

AI-powered decision making:

• Usage Pattern Analysis: Tracks and learns from usage patterns
• Provider Recommendations: Suggests best provider based on query type
• Peak Hour Detection: Identifies usage patterns over time
• Category Classification: Automatically categorizes queries
• Performance Tracking: Monitors provider and model performance
• Optimization Suggestions: Recommends improvements based on patterns

Plugin Documentation

Full plugin documentation: opencode-plugin/README.md

Quick Start

Verifying Plugin Visibility

After installation, verify that Sage Agent is visible in both CLIs:

# Verify installation status
python cli.py doctor

# Expected output:
# {
#   "opencode_plugin_registered": true,     ← Plugin visible in OpenCode CLI
#   "claude_mcp_registered": true,          ← MCP tool visible in Claude Code CLI
#   ...
# }

In OpenCode CLI:

• Plugin is listed in the available plugins
• Run sage --interactive to start
• Commands: sage, sage-stats, sage-memory

In Claude Code CLI:

• MCP tool "sage-agent" is available
• Listed in available tools/integrations
• Use directly: "Use sage-agent to process this query"

OpenCode CLI

./run.sh --interactive
# or if installed as a package
sage-agent run --interactive

Available commands:

• models - List all available models
• run <prompt> - Execute a prompt with self-improvement
• stats - Display system statistics
• exit - Exit interactive mode

Claude Code CLI

After installation, the MCP server is automatically configured. Restart Claude Code and use:

User: Can you use sage-agent to process this query?
Query: "Explain JWT authentication implementation"

The agent will:

1. Check if this exact query was asked before
2. Recall similar past interactions
3. Apply advanced optimization
4. Validate the response
5. Remember the interaction for future learning

Available MCP tools:

• process_query - Process queries with full self-improvement
• remember_interaction - Manually store interactions
• provide_feedback - Submit feedback for learning (rating 1-5)
• add_knowledge - Add entries to knowledge base
• get_stats - Retrieve comprehensive statistics
• search_knowledge - Search the knowledge base
• recall_memory - Recall similar past interactions

Programmatic Usage

from src.rlm import EnterpriseRLM

# Initialize the self-improving agent
rlm = EnterpriseRLM()

# Process a query - agent automatically learns and improves
result = rlm.process_query(
    query="How to implement REST API authentication?",
    provider="openai",
    model="gpt-4",
    use_advanced_optimization=True
)

# Check if response came from memory (no duplication)
if result["from_memory"]:
    print(f"Retrieved from memory in {result['processing_time']}s")
    print(f"Tokens saved: {result['tokens_saved']}")
else:
    print(f"New query processed")
    print(f"Similar memories: {result['similar_memories']}")
    print(f"Suggestions: {result['improvement_suggestions']}")

# Interaction is automatically remembered and validated
# No manual remember_interaction needed when using RLMEnabledLLMAgent

# Provide feedback for continuous improvement
rlm.provide_feedback(
    query="How to implement REST API authentication?",
    response=result["response"],
    feedback="Excellent explanation",
    rating=5  # 1-5 scale
)

# Add custom knowledge
rlm.add_knowledge(
    id="jwt_best_practices",
    category="security",
    title="JWT Best Practices",
    content="Use HTTPS, set expiration, validate tokens...",
    tags=["auth", "jwt", "security"],
    priority=9
)

Self-Improvement System

The agent automatically improves with every interaction. No manual intervention required.

How It Works

# First query - agent learns
result1 = rlm.process_query("What is JWT?")
# 1. Checks memory (not found)
# 2. Processes query
# 3. Validates response
# 4. Stores in memory
# 5. Learns patterns

# Provide feedback
rlm.provide_feedback(
    query="What is JWT?",
    response=result1["response"],
    feedback="Good but needs more detail",
    rating=3
)
# Agent learns: "JWT" queries need more detail

# Similar query - agent recalls and improves
result2 = rlm.process_query("Explain JWT authentication")
# 1. Recalls similar query
# 2. Applies learned improvements
# 3. Provides more detailed response
print(result2["improvement_suggestions"])
# ["Be more detailed based on past feedback"]

# Exact query - instant recall
result3 = rlm.process_query("What is JWT?")
print(result3["from_memory"])  # True
print(result3["processing_time"])  # < 0.001s

Automatic Features

Every query automatically triggers:

1. Memory Check: Searches for exact or similar past queries
2. Pattern Learning: Extracts and learns patterns from query
3. Response Validation: Checks for hallucinations and quality
4. Storage: Permanently stores interaction
5. Improvement: Updates optimization strategies

Quality Tracking

# Get quality trend
stats = rlm.get_comprehensive_stats()
trend = stats['improvement']['quality_trend']

print(f"Trend: {trend['trend']}")  # improving/stable/declining
print(f"Quality: {trend['current_quality']}")  # e.g., "85.5%"
print(f"Change: {trend['improvement']}")  # e.g., "+5.2%"

Learned Insights

# Get what the agent has learned
insights = rlm.memory.get_learned_insights()

print(f"Total memories: {insights['total_memories']}")
print(f"Patterns learned: {insights['learned_patterns']}")
print(f"Success rate: {insights['success_rate']}%")
print(f"Top topics: {insights['top_topics']}")
