Overview

AURORA is a cognitive architecture framework that provides intelligent context management, reasoning, and agent orchestration capabilities for AI systems. Built on principles inspired by cognitive science research (SOAR, ACT-R), AURORA enables AI agents to maintain persistent memory, learn from experience, and efficiently coordinate complex tasks.

Key Features

v0.2.0 - MCP Integration:

• Claude Desktop Integration: 5 MCP tools for seamless codebase interaction in Claude
• Single Package Installation: One command to install all AURORA components
• Cross-Platform Support: Windows, macOS, and Linux fully supported
• Installation Verification: Health checks and diagnostics with aur --verify
• Improved Error Handling: Actionable error messages with recovery steps
• Flexible CLI Syntax: Support for both aur --headless and aur headless patterns

Phase 1 Foundation:

• Intelligent Context Management: Adaptive chunking and retrieval of code and reasoning contexts
• Persistent Memory: SQLite-based storage with activation-based retrieval
• Code Understanding: Tree-sitter powered parsing for Python (extensible to other languages)
• Agent Registry: Discover and orchestrate AI agents based on capabilities
• Flexible Configuration: JSON schema validated configuration with environment overrides
• Comprehensive Testing: Unit, integration, and performance testing framework

Phase 2 SOAR Pipeline:

• 9-Phase SOAR Orchestrator: Assess → Retrieve → Decompose → Verify → Route → Collect → Synthesize → Record → Respond
• Multi-Stage Verification: Self-verification (Option A) and adversarial verification (Option B) with retry loops
• LLM Integration: Abstract LLM client supporting multiple providers (Anthropic Claude, OpenAI, Ollama)
• Cost Management: Token tracking, budget enforcement with soft/hard limits, provider-specific pricing
• ReasoningChunk System: Full ACT-R pattern caching with success scoring and learning updates
• Conversation Logging: Markdown formatted logs with full execution traces
• Performance: Simple queries <2s, complex queries <10s, keyword-based optimization bypasses LLM for 60-70% of queries

Phase 3 Advanced Memory & Features:

• ACT-R Activation Engine: BLA (frequency/recency), spreading activation, context boost, decay penalty - cognitively-inspired memory retrieval
• Semantic Embeddings: sentence-transformers integration, hybrid scoring (60% activation + 40% semantic similarity)
• Headless Reasoning Mode: Autonomous goal-driven execution with safety (git branch enforcement, budget limits, iteration caps)
• Multi-Tier Caching: Hot cache (LRU 1000 chunks) + persistent cache + activation scores cache (10min TTL) → 30%+ hit rate
• Query Optimization: Type pre-filtering, threshold filtering, batch activation calculation → <500ms for 10K chunks
• Production Resilience: Retry handler (exponential backoff), rate limiter (token bucket), metrics collector, alerting system → 95%+ recovery rate

MCP Integration with Claude Desktop (Primary Workflow)

AURORA v0.2.0 integrates with Claude Desktop via the Model Context Protocol, enabling Claude to search and analyze your codebase directly.

1. Install and Index

# Install AURORA
pip install aurora[all]

# Initialize configuration (optional - sets API keys)
aur init

# Index your codebase
cd /path/to/your/project
aur mem index .

2. Configure Claude Desktop

Add AURORA to Claude Desktop's MCP configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "aurora": {
      "command": "python",
      "args": ["-m", "aurora.mcp.server"]
    }
  }
}

3. Use in Claude Desktop

Restart Claude Desktop and ask questions about your code:

• "Search my codebase for authentication logic"
• "Find all usages of the DatabaseConnection class"
• "What does the UserService module do?"
• "Show me error handling in payment processing"

Claude will automatically use AURORA's tools to search your indexed codebase and provide contextual answers.

See: MCP Setup Guide for detailed configuration and troubleshooting.

Standalone CLI Usage

You can also use AURORA's CLI directly without Claude Desktop:

Basic Queries

# Simple query (uses direct LLM - fast)
aur query "What is a Python decorator?"

# Complex query (uses full AURORA pipeline with memory context)
aur query "How does the authentication system work?"

# Force specific mode
aur query "Explain classes" --force-aurora --verbose

# Show escalation reasoning
aur query "Design API endpoints" --show-reasoning

# Test configuration without API calls
aur query "test" --dry-run

Memory Management

# Index current directory
aur mem index

# Search indexed code
aur mem search "authentication"

# View statistics
aur mem stats

# Advanced search
aur mem search "database" --limit 10 --show-content --format json

Headless Mode (Autonomous Experiments)

# Run autonomous experiment (both syntaxes work)
aur headless experiment.md
aur --headless experiment.md

# Custom budget and iterations
aur headless experiment.md --budget 10.0 --max-iter 20

# Dry run (validation only)
aur headless experiment.md --dry-run

Verification and Troubleshooting

# Check installation health
aur --verify

# Check MCP server status
aurora-mcp status

# View help
aur --help
aur mem --help

Python API Usage

Example 1: Parse and Store Code

from aurora_core.store import SQLiteStore
from aurora_context_code import PythonParser

# Initialize storage
store = SQLiteStore("aurora.db")

# Parse Python code
parser = PythonParser()
chunks = parser.parse_file("example.py")

# Store chunks with metadata
for chunk in chunks:
    store.save_chunk(chunk)
    print(f"Stored: {chunk.metadata.get('name')} "
          f"(complexity: {chunk.metadata.get('complexity', 0)})")

# Example output:
# Stored: authenticate_user (complexity: 5)
# Stored: validate_token (complexity: 3)
# Stored: UserManager (complexity: 8)

Example 2: Context Retrieval with Scoring

from aurora_core.context import CodeContextProvider
from aurora_context_code.registry import ParserRegistry

# Initialize provider with automatic parser discovery
registry = ParserRegistry()
provider = CodeContextProvider(store, registry)

# Query for relevant code chunks
results = provider.retrieve(
    query="authentication logic",
    max_results=5
)

for chunk in results:
    name = chunk.metadata.get('name', 'unknown')
    score = chunk.metadata.get('_score', 0.0)
    file_path = chunk.metadata.get('file_path', 'unknown')

    print(f"{name} (score: {score:.2f})")
    print(f"  File: {file_path}")
    print(f"  Lines: {chunk.start_line}-{chunk.end_line}")
    print(f"  Signature: {chunk.metadata.get('signature', 'N/A')}\n")

# Example output:
# authenticate_user (score: 0.85)
#   File: /app/auth/manager.py
#   Lines: 45-67
#   Signature: def authenticate_user(username: str, password: str) -> bool
#
# validate_token (score: 0.72)
#   File: /app/auth/tokens.py
#   Lines: 23-41
#   Signature: def validate_token(token: str) -> dict[str, Any]

Example 3: Agent Discovery and Selection

from aurora_soar import AgentRegistry

# Initialize registry with discovery paths
registry = AgentRegistry(
    discovery_paths=[
        "./config/agents",
        "~/.aurora/agents",
        "/etc/aurora/agents"
    ]
)

# Find agents by capability
code_agents = registry.find_by_capability("code-generation")
for agent in code_agents:
    print(f"{agent.name} ({agent.agent_type})")
    print(f"  Capabilities: {', '.join(agent.capabilities)}")
    print(f"  Endpoint: {agent.endpoint or agent.path}\n")

# Get agent for specific domain
python_agent = registry.get_agent_for_domain("python")
if python_agent:
    print(f"Using {python_agent.name} for Python tasks")

# Example output:
# CodeLlama (remote)
#   Capabilities: code-generation, code-explanation, refactoring
#   Endpoint: http://localhost:8000/api/v1
#
# Local Python Expert (local)
#   Capabilities: code-generation, code-review
#   Endpoint: /usr/local/bin/python-agent

Example 4: Configuration Management

from aurora_core.config import Config
import os

# Set environment overrides
os.environ['AURORA_STORAGE_PATH'] = '/custom/data/aurora.db'
os.environ['AURORA_PARSER_CACHE_TTL'] = '3600'

# Load configuration with override hierarchy
config = Config.load(
    config_files=[
        "/etc/aurora/config.json",      # Global defaults
        "~/.aurora/config.json",         # User overrides
        "./aurora.config.json"           # Project overrides
    ],
    cli_overrides={
        'logging.level': 'DEBUG'
    }
)

# Access configuration with type safety
storage_path = config.get_string('storage.path')
cache_ttl = config.get_int('parser.cache_ttl')
log_level = config.get_string('logging.level')

print(f"Storage: {storage_path}")
print(f"Cache TTL: {cache_ttl}s")
print(f"Log Level: {log_level}")

# Example output:
# Storage: /custom/data/aurora.db
# Cache TTL: 3600s
# Log Level: DEBUG

Example 5: End-to-End Workflow

from aurora_core.store import SQLiteStore
from aurora_core.config import Config
from aurora_context_code.registry import ParserRegistry
from aurora_core.context import CodeContextProvider
from pathlib import Path

# 1. Load configuration
config = Config.load()

# 2. Initialize components
store = SQLiteStore(config.get_string('storage.path'))
parser_registry = ParserRegistry()
context_provider = CodeContextProvider(store, parser_registry)

# 3. Parse project files
project_root = Path('./my_project')
python_files = project_root.rglob('*.py')

parsed_count = 0
for py_file in python_files:
    parser = parser_registry.get_parser(str(py_file))
    if parser:
        chunks = parser.parse_file(str(py_file))
        for chunk in chunks:
            store.save_chunk(chunk)
        parsed_count += len(chunks)

print(f"Parsed {parsed_count} chunks from project")

# 4. Query for specific functionality
query = "database connection pooling"
results = context_provider.retrieve(query, max_results=10)

print(f"\nFound {len(results)} relevant chunks for: '{query}'")
for chunk in results[:3]:  # Show top 3
    print(f"  - {chunk.metadata.get('name')} "
          f"in {Path(chunk.metadata.get('file_path')).name}")

# 5. Update activation (track usage)
for chunk in results[:5]:
    context_provider.update(chunk.chunk_id)

# Example output:
# Parsed 247 chunks from project
#
# Found 8 relevant chunks for: 'database connection pooling'
#   - DatabasePool in db_manager.py
#   - create_pool in connection.py
#   - get_connection in pool_handler.py

# Initialize cost tracker with monthly budget
tracker = CostTracker(
    monthly_limit_usd=10.0,
    config_path="~/.aurora/budget_tracker.json"
)

# Check budget before query
budget_ok, status = tracker.check_budget(estimated_cost_usd=0.50)
if not budget_ok:
    print(f"Budget exceeded: {status}")
else:
    # Execute query
    result = orchestrator.execute(query="...", budget_tracker=tracker)

    # Cost automatically tracked by orchestrator
    print(f"Query cost: ${result['metadata']['cost_usd']:.4f}")

# Budget Status:
#   Consumed: $6.78
#   Remaining: $3.22
#   Limit: $10.00
#   Usage: 67.8%

Example 9: ReasoningChunk Pattern Caching

from aurora_core.chunks import ReasoningChunk

# Orchestrator automatically creates ReasoningChunks after successful queries
result = orchestrator.execute(query="Implement JWT authentication")

# Pattern cached if success_score >= 0.5
if result['metadata']['pattern_cached']:
    print("Pattern cached for future reuse")
    print(f"Success score: {result['metadata']['success_score']:.2f}")

# Later queries with similar patterns retrieve cached reasoning
similar_result = orchestrator.execute(query="Add OAuth2 authentication")
