Goalie 🥅 - Goal-Oriented AI Research with Anti-Hallucination

AI-Powered Research Assistant: Goalie uses Goal-Oriented Action Planning (GOAP) to break down complex research questions into manageable steps. It leverages the Perplexity API for web searches and includes anti-hallucination features to improve accuracy.

Created by rUv - Building the future of verifiable AI research

🚀 Quick Start

# Install and run in under 30 seconds
npx goalie

# Or install globally
npm install -g goalie

# Set your Perplexity API key (get one at https://perplexity.ai/settings/api)
export PERPLEXITY_API_KEY="pplx-your-key-here"
# Or add to .env file:
echo 'PERPLEXITY_API_KEY="pplx-your-key-here"' >> .env

# Start researching immediately
goalie search "Your research question here"

🔌 MCP (Model Context Protocol) Integration

Goalie works seamlessly with AI assistants like Claude through MCP:

# Start as MCP server
npx goalie start

# Or add to your Claude MCP config (~/.config/claude/claude_desktop_config.json):
{
  "mcpServers": {
    "goalie": {
      "command": "npx",
      "args": ["goalie", "start"],
      "env": {
        "PERPLEXITY_API_KEY": "your-key-here"
      }
    }
  }
}

Once configured, Claude can use advanced research capabilities directly through natural language!

🎯 What Makes Goalie Different from Traditional Deep Research Systems?

Unlike traditional AI search tools that provide single-shot answers with limited sources, Goalie is a deep research system that:

1. Goal-Oriented Planning (GOAP)

• Decomposes complex questions into multiple research goals
• Creates intelligent action plans using A* pathfinding algorithms
• Dynamically re-plans when actions fail (up to 3 attempts)
• Optimizes research paths for efficiency and completeness

2. Anti-Hallucination Features

• Citation Tracking: Attempts to provide sources for claims
• Ed25519 Cryptographic Signatures: ✅ REAL Ed25519 implementation (v1.2.9+)
• Basic Validation: Checks for obvious false claims
• Contradiction Detection: Flags some conflicting information
• Confidence Scoring: Provides estimated reliability scores

3. Deep Research vs Simple Search

Feature	Traditional AI Search	Goalie Deep Research
Sources	2-5 sources	5-15 sources (typical)
Planning	Single query	Multi-step GOAP planning
Verification	Basic or none	Citation tracking + validation
Hallucination Protection	Limited	Enhanced with multiple checks
Failure Recovery	None	Automatic re-planning (3x)
Output	Simple answer	Structured research report
Contradiction Handling	Ignored	Detected and flagged
Cost	$0.001-0.003	$0.01-0.05 (estimated)

🛡️ How Anti-Hallucination & Grounding Works

Goalie implements multiple layers of protection against AI hallucination:

1. Citation Tracking

// Goalie attempts to provide sources for claims
{
  "claim": "Tesla's revenue grew 35% in Q3",
  "source": "Based on search results",
  "url": "Source URL if available",
  "confidence": 0.75  // Estimated confidence
}

2. Ed25519 Framework (✅ REAL Implementation - v1.2.9+)

• Signature Support: ✅ Real Ed25519 cryptographic signatures using @noble/ed25519
• Verification Logic: ✅ Actual signature verification and tamper detection
• Performance: ✅ ~3ms per sign+verify operation
• Status: ✅ Production-ready - see ED25519-USAGE.md and VALIDATION-REPORT.md

3. Validation Approach

• Multiple Searches: Can query multiple sources via Perplexity
• Basic Contradiction Check: Identifies some conflicts
• Confidence Estimates: Provides reliability scores (not guaranteed accurate)
• Best Effort: Validation quality depends on available sources

4. GOAP Planning

• Action Planning: Breaks down research into steps
• Re-planning Support: Can retry up to 3 times if configured
• Sequential Execution: Runs search steps in order
• Partial Results: Returns what it finds

🔍 How Goalie Works

Query: "What are the side effects of medication X?"

Goalie Process:
1. Uses Perplexity API to search web sources
2. Attempts to extract relevant information
3. Provides citations when available
4. Checks for obvious contradictions
5. Estimates confidence scores
6. Returns structured results

🔒 Advanced Security: Ed25519 Anti-Hallucination

What is Ed25519 Verification?

Ed25519 is a cryptographic signature system that ensures information hasn't been tampered with or made up. Think of it like a tamper-proof seal on important documents.

When to Use It

• Legal Research: Ensure sources are authentic
• Financial Analysis: Verify data hasn't been altered
• Medical Information: Confirm sources are legitimate
• Due Diligence: Create audit trail of verified sources

How to Enable (Experimental)

# Note: These features are partially implemented.
# The CLI accepts these parameters but full cryptographic verification is not yet functional.

# Basic verification attempt
goalie search "Your query" \
  --verify

# Require signatures (experimental - not fully functional)
goalie search "Your query" \
  --verify \
  --strict-verify \
  --trusted-issuers "reuters.com,bloomberg.com,sec.gov"

# Sign results (requires manual key setup - experimental)
goalie search "Your query" \
  --sign \
  --sign-key "base64-encoded-private-key" \
  --key-id "your-key-id"

Certificate Chain Example

// Research with mandate certificates
{
  "ed25519Verification": {
    "enabled": true,
    "requireSignatures": true,
    "certChain": [
      {
        "issuer": "research-lab.org",
        "subject": "financial-data",
        "validUntil": "2025-12-31"
      }
    ]
  }
}

💡 Pro Tips for Better Research

1. Be Specific

# ❌ Too vague
"tax advice"

# ✅ Specific and actionable
"What are the 2024 tax deductions for home-based freelance graphic designers in California?"

2. Use Domain Filters for Authority

# For legal research
--domains "law.cornell.edu,justia.com,findlaw.com"

# For medical research
--domains "nih.gov,mayo.edu,nejm.org"

# For financial research
--domains "sec.gov,federalreserve.gov,imf.org"

3. Set Recency for Current Information

--recency day    # Breaking news, current events
--recency week   # Recent developments
--recency month  # Current trends
--recency year   # Comprehensive overview

4. Use Output Formats Wisely

--format markdown  # For reading and sharing
--format json      # For data analysis
--format both      # For complete documentation

🔍 Understanding the Difference: Deep Research vs Quick Search

Quick Search (raw)

goalie raw "What is an LLC?"
# Returns: Basic definition, 5-7 sources
# Time: 2-3 seconds
# Best for: Quick facts, definitions

Deep Research (search)

goalie search "Complete analysis of LLC vs S-Corp for SaaS startup"
# Returns:
# - Tax implications by state
# - Filing requirements timeline
# - Cost comparisons
# - Case studies
# - Expert recommendations
# - 25-30 sources
# Time: 15-30 seconds
# Best for: Decisions, analysis, comprehensive understanding
