AURORA: Adaptive Unified Reasoning and Orchestration Architecture with MCP Integration

Aurora

Memory-First Planning & Multi-Agent Orchestration Framework

Version 0.6.5 | PyPI | Commands | Docs

Aurora is a local-first development automation framework that uses ACT-R memory, SOAR decomposition, and multi-agent orchestration to systematically break down goals and coordinate specialized agents—all without requiring API access.

Built on planning principles adapted from OpenSpec.

---

What Aurora Actually Is

Aurora provides three core capabilities:

Memory (ACT-R)

Intelligent code indexing that learns from usage patterns. Your codebase's memory works like human memory—frequently accessed code stays "hot", rarely used code fades.

Technology:

• ACT-R activation scores (chunks strengthen/weaken with use)
• BM25 keyword search (fast, reliable, local)
• Git-aware indexing (respects .gitignore, tracks changes)
• Tree-sitter parsing (understands code structure)
• Optional semantic search (if you want it)

Use case: aur mem index . ->aur mem search "authentication"

Planning (SOAR + OpenSpec)

Systematic goal decomposition with agent matching and gap detection. Breaks high-level goals into actionable subgoals with automatic agent assignment.

Technology:

• SOAR 9-phase pipeline (assess ->retrieve ->decompose ->verify ->route)
• Agent capability matching with LLM fallback
• Gap detection (identifies missing agent capabilities early)
• Memory-aware (uses indexed code to inform planning)
• OpenSpec-inspired workflow (goals ->PRD ->tasks)

Use case: aur goals "Add OAuth2 auth" ->/plan ->/implement

Orchestration (Multi-Agent)

CLI-agnostic agent execution with parallel/sequential coordination. Routes tasks to specialized agents without API lock-in.

Technology:

• Works with 20+ CLI tools (claude, cursor, aider, etc.)
• Subprocess-based execution (local-first)
• Dependency-aware scheduling (parallel + sequential)
• Agent specialization (right tool for right job)

Use case: /implement executes tasks sequentially, aur spawn tasks.md executes in parallel

---

What Aurora Is NOT

Not deep reasoning - Aurora uses structured decomposition, not chain-of-thought reasoning like o1 Not API-dependent - Core functionality works locally with any CLI tool Not magical AI - It's systematic orchestration, not AGI Not a replacement for thinking - It's a framework for organizing development work

---

Quick Start

# Install
pip install aurora-actr

# Initialize project
cd your-project/
aur init

# Index your codebase
aur mem index .

# Search indexed memory
aur mem search "authentication logic"

# Answer complex questions with SOAR reasoning
aur soar "How does the payment flow work?"

# Planning flow: Goal ->PRD ->Tasks ->Implementation
aur goals "Add Stripe payment processing" \
  --context src/checkout/ \
  --verbose

# Output: .aurora/plans/0001-add-stripe-payment/goals.json
# Contains: 5 subgoals, agent assignments, memory context, gaps

# Navigate to plan directory
cd .aurora/plans/0001-add-stripe-payment/

# Generate PRD and tasks (in Claude Code/Cursor/etc.)
/plan

# Execute tasks sequentially with specialized agents
/implement

# Alternative: Execute tasks in parallel (faster but less controlled)
aur spawn tasks.md --verbose

# Health check
aur doctor

The Planning Flow

+---------------+     +---------------+     +---------------+

|               |     |               |     |               |
| SOAR          |     | OpenSpec      |     | Sequential    |
| decomposes    |     | generates     |     | execution     |
| goal into     |     | PRD +         |     | with          |
| subgoals      |     | tasks.md      |     | specialized   |
| with agents   |     |               |     | agents        |
+---------------+     +---------------+     +---------------+
      |                     |                      |
      v                     v                      v
  goals.json           PRD + tasks            Implemented
  (structured)         (detailed)             (tested)

Alternative parallel execution:
                                          +---------------+
                                          |  aur spawn    |
                                          |               |
                                          | Parallel      |
                                          | execution     |
                                          | (faster)      |
                                          +---------------+

Primary workflow:

• aur goals ->SOAR decomposition with agent matching
• /plan ->Generate PRD and tasks (Claude Code skill)
• /implement ->Execute tasks sequentially, one by one

Alternative:

• aur spawn tasks.md ->Execute tasks in parallel (faster, less control)

Configuration

• Multi-tier resolution - CLI flag ->env var ->project config ->global config ->default
• Tool/model selection - Per-command configuration
• Project-local - .aurora/config.json overrides global settings

---

Installation

Standard (Lightweight)

pip install aurora-actr  # ~520KB, BM25 + activation only

With Semantic Search (Optional)

pip install aurora-actr[ml]  # +1.9GB, adds sentence-transformers

Note: The ML package uses all-MiniLM-L6-v2 by default. To use different embedding models (OpenAI, Cohere, custom models), see the ML Models Guide.

Development

git clone https://github.com/amrhas82/aurora.git
cd aurora
./install.sh

---

What Gets Indexed

Aurora indexes three types of chunks:

• code - Functions, classes, methods (tree-sitter AST parsing)
• kb - Markdown documentation (README.md, docs/, PRDs)
• soar - Reasoning patterns (auto-saved from aur soar queries)

Default exclusions: .git/, venv/, node_modules/, tasks/, CHANGELOG.md, LICENSE*, build/, dist/

Custom exclusions: Create .auroraignore (gitignore-style patterns):

# .auroraignore example
tests/**
docs/archive/**
*.tmp

---

Retrieval Strategy

Hybrid scoring (default, no ML required):

• 40% BM25 keyword matching
• 30% ACT-R activation (usage frequency + recency)
• 30% Git signals (modification patterns)

With ML option ([ml]):

• 30% BM25 keyword matching
• 40% Semantic similarity (sentence-transformers)
• 30% ACT-R activation

Speed: Sub-500ms on 10K+ chunks.

Custom models: See ML Models Guide for using OpenAI, Cohere, or custom embedding models.

Architecture

SOAR Pipeline (9 Phases)

Two execution modes:

1. Query Mode (aur soar) - Answer questions about code

• Uses all 9 phases to gather info and synthesize answers
• Executes research agents to collect data
• Returns natural language answer with citations

2. Goals Mode (aur goals) - Decompose goals for planning

• Uses phases 1-5, 8-9 (skips execution/synthesis)
• Matches subgoals to agents, detects gaps
• Returns structured goals.json for /plan skill

9 Phases:

1. Assess - Determine complexity (keyword + optional LLM)
2. Retrieve - Get relevant context from ACT-R memory
3. Decompose - Break goal into subgoals with agent assignments
4. Verify - Validate decomposition (self or adversarial)
5. Route - Match agents, detect capability gaps
6. Collect - Execute agents (query mode only)
7. Synthesize - Combine outputs (query mode only)
8. Record - Cache successful patterns
9. Respond - Format output (answer or goals.json)

OpenSpec-Inspired Planning

Aurora's planning workflow is inspired by and adapted from OpenSpec:

Core workflow:

• goals.json - Structured goal representation with subgoals
• PRD generation - Detailed product requirements from goals
• Task breakdown - Actionable tasks with agent assignments
• Implementation tracking - Sequential execution with validation

Aurora's extensions:

• ACT-R memory integration for context-aware planning
• SOAR decomposition for systematic goal breakdown
• Agent capability matching with gap detection
• CLI-agnostic multi-agent orchestration

Design Principles

1. Memory-First - ACT-R activation as cognitive foundation
2. Local Execution - No cloud APIs required for core features
3. CLI-Agnostic - Works with any tool, no vendor lock-in
4. Systematic Over Magical - Structured pipelines, not black boxes
5. Honest Capabilities - We decompose and orchestrate, we don't "reason deeply"
6. OpenSpec-Inspired - Proven planning workflow patterns
