**Advanced deep research system using Goal-Oriented Action Planning (GOAP) with built-in anti-hallucination and cryptographic source verification**

## 🚀 Quick Start

```bash
# Install and run in under 30 seconds
npx goalie

# Set your Perplexity API key (get one at https://perplexity.ai/settings/api)
export PERPLEXITY_API_KEY="pplx-your-key-here"

# Start researching immediately
goalie test --query "Your research question here"
```

## 🔌 MCP (Model Context Protocol) Integration

Goalie works seamlessly with AI assistants like Claude through MCP:

```bash
# 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 Technology**
- **100% Citation Grounding**: Every claim must have a verifiable source
- **Ed25519 Cryptographic Verification**: Optional digital signatures for source authenticity
- **Cross-Reference Validation**: Important facts verified across multiple sources
- **Contradiction Detection**: Automatically identifies and flags conflicting information
- **Confidence Scoring**: Shows reliability percentage for each finding (avg 89.5%)

### 3. **Deep Research vs Simple Search**

| Feature | Traditional AI Search | Goalie Deep Research |
|---------|----------------------|---------------------|
| **Sources** | 2-5 sources | 20-30+ sources |
| **Planning** | Single query | Multi-step GOAP planning |
| **Verification** | Basic or none | Cryptographic + cross-reference |
| **Hallucination Protection** | Limited | 100% citation grounding |
| **Failure Recovery** | None | Automatic re-planning (3x) |
| **Output** | Simple answer | Structured research report |
| **Contradiction Handling** | Ignored | Detected and flagged |
| **Cost** | $0.001-0.003 | $0.006-0.10 |

## 🛡️ How Anti-Hallucination & Grounding Works

Goalie implements multiple layers of protection against AI hallucination:

### 1. **Mandatory Citation Grounding**
```javascript
// Every factual claim requires a source
{
  "claim": "Tesla's revenue grew 35% in Q3",
  "source": "SEC Filing 10-Q, October 2024",
  "url": "https://sec.gov/Archives/edgar/data/1318605/...",
  "confidence": 0.95
}
```

### 2. **Ed25519 Cryptographic Verification**
- **Digital Signatures**: Sources can be cryptographically signed
- **Chain of Trust**: Mandate certificates verify authenticity
- **Tamper Detection**: Ensures data hasn't been modified
- **Trusted Issuers**: Whitelist authoritative sources

### 3. **Multi-Source Validation**
- **Cross-Reference Engine**: Facts checked across 3+ sources
- **Contradiction Detection**: Flags conflicting information
- **Consensus Building**: Uses majority agreement
- **Confidence Scoring**: 0-100% reliability ratings

### 4. **GOAP Planning with Replanning**
When initial searches fail or return insufficient data:
- **Automatic Re-planning**: Creates alternative research paths
- **Failure Recovery**: Up to 3 re-planning attempts
- **Adaptive Strategies**: Adjusts approach based on failures
- **Graceful Degradation**: Returns partial results if needed

## 🔍 Example: How Goalie Prevents Hallucination

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

Traditional AI: "Common side effects include..."
              [May invent plausible-sounding effects]

Goalie:
1. Searches FDA.gov, clinical trials, medical journals
2. Requires citation for EVERY side effect mentioned
3. Cross-references across 5+ medical sources
4. Flags any contradictions between sources
5. Provides confidence score for each finding
6. Signs results with Ed25519 if enabled
```

## 🎯 Key Features That Prevent Hallucination

### Grounding Capabilities
- **100% Citation Requirement**: No unsourced claims allowed
- **Real-time Verification**: Checks sources as it researches
- **URL Validation**: Ensures all links are real and active
- **Quote Extraction**: Pulls exact quotes from sources
- **Timestamp Tracking**: Records when information was retrieved

### Advanced Reasoning Plugins
- **Chain-of-Thought**: Explores multiple reasoning paths
- **Self-Consistency**: Runs multiple samples for consensus
- **Anti-Hallucination Plugin**: Dedicated fact-checking layer
- **Agentic Research**: Multiple AI agents verify each other

### Cryptographic Security (Optional)
```bash
# Enable full cryptographic verification

## 🔒 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
```bash
# Basic verification - check existing signatures
goalie test --query "Your query" \
  --verify-signatures

# Require all sources to be signed
goalie test --query "Your query" \
  --require-signatures \
  --trusted-issuers "reuters.com,bloomberg.com,sec.gov"

# Sign your research results
goalie test --query "Your query" \
  --sign-results \
  --key-id "your-key-id"
```

### Certificate Chain Example
```javascript
// 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
```bash
# ❌ 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
```bash
# 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
```bash
--recency day    # Breaking news, current events
--recency week   # Recent developments
--recency month  # Current trends
--recency year   # Comprehensive overview
```

### 4. Use Output Formats Wisely
```bash
--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 (search.raw)
```bash
goalie test --raw --query "What is an LLC?"
# Returns: Basic definition, 5-7 sources
# Time: 2-3 seconds
# Best for: Quick facts, definitions
```

### Deep Research (goap.search)
```bash
goalie test --query "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
```
