+Enforces deployment compliance by analyzing PRs against SOP policies:
 
-## OpsMate Extension (Coming Soon)
+- **Linear-GitHub Integration**: Links PRs to Linear issues
+- **SOP Compliance**: Validates against deployment policies
+- **Risk Scoring**: Calculates risk from graph context (Neo4j)
+- **LLM-Powered**: Uses OpenRouter + local Ollama models with fallback
 
-The following agents are being added for AWS cost optimization:
+### Watchman: Night Watchman
 
-| Agent | Purpose |
-|-------|---------|
-| **Watchman** | Auto-shutdown staging when team is offline |
-| **Hunter** | Find and cleanup unattached EBS volumes |
-| **Guard** | Revoke IAM access on team departure |
+Auto-shutdown staging instances when:
+- Team is offline (no commits in 30 min)
+- Within quiet hours (configurable, default 8PM-8AM)
+- No urgent tickets in progress
 
-### Compliance Rules
+### Hunter: Zombie Hunter
 
-| Rule | Condition | Decision |
-|------|-----------|----------|
-| Linear Issue | No issue linked | BLOCK |
-| Issue State | Not IN_PROGRESS or REVIEW | WARN |
-| Needs Spec | Issue has "Needs Spec" label | WARN |
-| Valid PR | All checks pass | PASS (auto-approve) |
+Finds unattached AWS resources:
+- EBS volumes with no attached instances
+- Old snapshots not referenced by volumes
+- Reports monthly waste with Slack alerts
+
+### Guard: Access Guard
+
+Detects departed team members:
+- IAM users not in Slack/GitHub
+- Inactive users (90+ days no activity)
+- Revoke access with Slack approval workflow
 
-### Project Structure
+## Intelligence Infrastructure
+
+### Persistent Memory (Redis)
+- Key-value storage with TTL support
+- Pattern-based memory recall
+- Agent memory mixin for easy integration
+
+### Fallback Chain (LLM)
+```
+Request → OpenRouter → [rate limit/error] → Ollama (local) → [fail] → Rule-based
+```
+
+### Circuit Breaker
+- Prevents cascading failures
+- Auto-recovery after timeout
+- Three states: CLOSED → OPEN → HALF_OPEN
+
+### Evaluation Framework
+- Decision tracking with human feedback
+- Accuracy metrics over time
+- Confidence calibration

+
+## Core Components
+
+### 1. Agents (`src/ai_service/agents/`)
+
+| Agent | Purpose | Capabilities |
+|-------|---------|--------------|
+| **Sentinel** | PR compliance & deployment policies | Linear-GitHub integration, SOP validation, risk scoring |
+| **Watchman** | Night Watchman | Auto-shutdown staging, quiet hours, team availability |
+| **Hunter** | Zombie Hunter | AWS resource cleanup, EBS volumes, snapshots |
+| **Guard** | Access Guard | IAM revocation, departed user detection |
+| **CFO** | Budget analysis | Invoice approval, spending patterns |
+| **CTO** | Tech debt analysis | Code review, debt tracking |
+
+#### Agent Structure
+```
+agents/
+├── sentinel/           # PR compliance agent
+│   ├── graph.py        # LangGraph definition
+│   ├── nodes.py        # Agent nodes (analyze, decide, act)
+│   ├── state.py        # Pydantic state model
+│   └── __init__.py
+├── watchman/           # Staging auto-shutdown
+├── hunter/             # AWS cleanup
+├── guard/              # Access management
+└── multi_agent.py      # Multi-agent supervisor/orchestrator
+```
+
+### 2. Memory System (`src/ai_service/memory/`)
+
+#### Redis Memory Store
+- **Hot storage** for agent context and recent decisions
+- TTL-based expiry for automatic cleanup
+- Pattern-based recall for searching memories
+- Connection pooling and singleton pattern
+
+```python
+from ai_service.memory.redis_store import RedisMemoryStore, AgentMemoryMixin
+
+class MyAgent(AgentMemoryMixin):
+    pass
+
+agent = MyAgent()
+agent.remember("user_preference", {"theme": "dark"})
+agent.recall("user_preference")
+```
+
+#### Neo4j Graph Memory
+- **Cold storage** for entity relationships
+- Temporal context tracking
+- Graph-based reasoning
+
+### 3. LLM Stack (`src/ai_service/llm/`)
+
+#### Fallback Chain Architecture
+```
+Request → OpenRouter → [FAIL] → Ollama (local) → [FAIL] → Rule-based
+              │              │               │
+              ▼              ▼               ▼
+         (Primary)     (Fallback 1)    (Fallback 2)
+```
+
+#### Circuit Breaker
+- Prevents cascading failures
+- States: CLOSED → OPEN → HALF_OPEN
+- Auto-recovery after timeout
+
+#### ResilientLLMClient
+```python
+from ai_service.llm.fallback import ResilientLLMClient
+
+client = ResilientLLMClient()
+result = await client.chat(messages=[...])
+# Automatically falls back if OpenRouter fails
+```
+
+### 4. Evaluation Framework (`src/ai_service/evaluation/`)
+
+#### Decision Tracking
+```python
+from ai_service.evaluation.metrics import DecisionRecord, DecisionStore
+
+# Record a decision
+decision = DecisionRecord(
+    decision_id="dec_123",
+    agent="sentinel",
+    event_type="pr_opened",
+    action="APPROVE",
+    confidence=0.85,
+    reasoning="All checks passed"
+)
+
+# Add human feedback
+decision.record_feedback("correct", "Agent made right call")
+```
+
+#### Metrics
+- **Accuracy**: Percentage of decisions approved by humans
+- **Confidence Calibration**: How well confidence matches actual accuracy
+- **A/B Testing**: Compare agent variants
+
+### 5. Integrations (`src/ai_service/integrations/`)
+
+| Integration | Purpose |
+|-------------|---------|
+| **GitHub** | PR events, status checks, repository access |
+| **Slack** | Alerts, approval workflows, notifications |
+| **AWS** | EC2 management, EBS volumes, cost analysis |
+| **Stripe** | Invoice processing, payment verification |
+| **Neo4j** | Graph database for relationships |
+
+### 6. SOP System (`src/ai_service/sop/`)
+
+Policy-based decision making:
+- `deployment_policy.md`: PR requirements, Friday rules, risk thresholds
+- `finance_policy.md`: Invoice approval limits, spending rules
+

+# Developer Guides
+
+## Adding a New Agent
+
+### 1. Create Agent Directory
+```bash
+mkdir -p src/ai_service/agents/new_agent
+```
+
+### 2. Define State Model (`state.py`)
+```python
+from pydantic import BaseModel
+from typing import Optional
+
+class NewAgentState(BaseModel):
+    event_data: dict
+    decision: Optional[str] = None
+    confidence: float = 0.0
+    reasoning: str = ""
+```
+
+### 3. Define Nodes (`nodes.py`)
+```python
+from langgraph.graph import StateGraph
+
+async def analyze(state: NewAgentState) -> NewAgentState:
+    # Analysis logic
+    return state
+
+async def decide(state: NewAgentState) -> NewAgentState:
+    # Decision logic
+    return state
+
+def create_graph() -> StateGraph:
+    graph = StateGraph(NewAgentState)
+    graph.add_node("analyze", analyze)
+    graph.add_node("decide", decide)
+    graph.set_entry_point("analyze")
+    graph.add_edge("analyze", "decide")
+    return graph.compile()
+```
+
+### 4. Register in Multi-Agent (`src/ai_service/agents/multi_agent.py`)
+```python
+from .new_agent import create_graph as create_new_agent
+
+AGENT_REGISTRY = {
+    "new_agent": create_new_agent,
+    # ... existing agents
+}
+```
+
+### 5. Add Tests
+```python
+# tests/test_new_agent.py
+import pytest
+from ai_service.agents.new_agent import create_graph
+
+@pytest.mark.asyncio
+async def test_new_agent_decision():
+    graph = create_graph()
+    result = await graph.ainvoke({"event_data": {...}})
+    assert result.decision is not None
+```
+
+## Writing LLM Evaluations
+
+### 1. Create Evaluation Test
+```python
+# tests/test_llm_eval.py
+import pytest
+from ai_service.llm.service import OllamaClient
+
+@pytest.mark.asyncio
+async def test_pr_decision():
+    client = OllamaClient()
+    result = await client.analyze_pr({
+        "title": "feat: add new feature",
+        "body": "This adds...",
+    })
+    assert result.decision in ["APPROVE", "WARN", "BLOCK"]
+```
+
+### 2. Run with Specific Model
+```bash
+OLLAMA_MODEL=tomng/lfm2.5-instruct:1.2b pytest tests/test_llm_eval.py -v
+```
+
+## Using Redis Memory Store
+
+### Basic Usage
+```python
+from ai_service.memory.redis_store import RedisMemoryStore
+
+store = RedisMemoryStore()
+
+# Store with TTL (24 hours)
+await store.store("user:123", {"name": "John"}, ttl_seconds=86400)
+
+# Recall by key
+value = await store.recall("user:123")
+
+# Pattern-based recall
+memories = await store.recall_by_pattern("user:*")
+```
+
+### Adding Memory to Agent
+```python
+from ai_service.memory.redis_store import AgentMemoryMixin
+
+class MyAgent(AgentMemoryMixin):
+    pass
+
+agent = MyAgent()
+agent.remember("context", {...})
+agent.recall("context")
+```
+
+## Circuit Breaker Usage
+
+### Manual Control
+```python
+from ai_service.llm.fallback import CircuitBreaker, CircuitState
+
+breaker = CircuitBreaker(failure_threshold=3, recovery_timeout=30.0)
+
+try:
+    await breaker.call(my_function)
+    await breaker.record_success()
+except Exception:
+    await breaker.record_failure()
+```
+
+### Using Decorator
+```python
+from ai_service.llm.fallback import with_circuit_breaker
+
+@with_circuit_breaker(breaker)
+async def risky_operation():
+    return await external_service_call()
+```
+
+## Recording Feedback
+
+### Submit Decision Feedback
+```python
+from ai_service.evaluation.metrics import DecisionStore
+
+store = DecisionStore()
+await store.record_feedback(
+    decision_id="dec_123",
+    feedback="correct",  # or "incorrect"
+    reasoning="Agent made the right call"
+)
+```
+
+### Calculate Accuracy
+```python
+from ai_service.evaluation.metrics import AccuracyCalculator
+
+accuracy = await AccuracyCalculator.calculate(
+    agent="sentinel",
+    time_window_days=30
+)
+print(f"Accuracy: {accuracy.percentage:.1%}")
+```
+
+## Running Tests
+
+### All Tests
+```bash
+pytest tests/ -v
+```
+
+### By Category
+```bash
+pytest tests/unit/ -v          # Unit tests
+pytest tests/integration/ -v    # Integration tests
+pytest tests/test_redis_memory.py -v  # Specific file
+```
+
+### With Coverage
+```bash
+pytest tests/ --cov=ai_service --cov-report=term-missing
+```
+
+### LLM Evaluation Tests
+```bash
+# Full evaluation
+pytest tests/test_llm_eval.py -v
+
+# Quick smoke test
+pytest tests/test_llm_eval_quick.py -v
+```
+
+## Debugging Tips
+
+### Enable Verbose Logging
+```bash
+LOG_LEVEL=DEBUG python -m ai_service.main
+```
+
+### Check Circuit Breaker Status
+```python
+from ai_service.llm.fallback import CircuitBreaker
+
+breaker = CircuitBreaker()
+print(f"State: {breaker.state}")
+print(f"Failures: {breaker.failure_count}")
+```
+
+### Redis Connection Test
+```python
+from ai_service.memory.redis_store import RedisClientSingleton
+
+connected = await RedisClientSingleton.health_check()
+print(f"Redis connected: {connected}")
+```

+## Implementation Order (TDD)
+
+### Phase 1: Core Infrastructure
+1. **Redis Memory Store** - Persistent key-value for agent memory
+2. **Circuit Breaker/Fallback** - Resilient LLM calls
+3. **Pydantic Structured Output** - Type-safe responses
+
+### Phase 2: API Endpoints
+4. **Enhanced FastAPI** - Events, feedback, agent status, history
+
+### Phase 3: LangGraph Integration
+5. **Checkpointer Setup** - Redis-backed state persistence
+6. **Evaluation Framework** - Metrics and tracking
+
+### Phase 4: Autonomous Execution
+7. **Scheduler** - Proactive background tasks

+
+## Key Design Decisions
+
+1. **Redis Checkpointer**: Use `langgraph.checkpoint.memory` for dev, Redis for prod
+2. **Structured Output**: Pydantic models for all LLM responses
+3. **Fallback Strategy**: OpenRouter → Ollama (local) → Rule-based
+4. **Memory Hierarchy**: Hot (Redis) → Cold (Neo4j) → Warm (In-memory cache)
+5. **Evaluation**: Track all decisions with human feedback for accuracy metrics
