**Before writing ANY code, you MUST check:**

### Step 1: Library Catalog
- Location: `.claude/library/catalog.json`
- If match >70%: REUSE or ADAPT

### Step 2: Patterns Guide
- Location: `.claude/docs/inventories/LIBRARY-PATTERNS-GUIDE.md`
- If pattern exists: FOLLOW documented approach

### Step 3: Existing Projects
- Location: `D:\Projects\*`
- If found: EXTRACT and adapt

### Decision Matrix
| Match | Action |
|-------|--------|
| Library >90% | REUSE directly |
| Library 70-90% | ADAPT minimally |
| Pattern exists | FOLLOW pattern |
| In project | EXTRACT |
| No match | BUILD (add to library after) |

## SOP Framework: 5-Phase RL Training Deployment

### Phase 1: Initialize Learning Environment (1-2 hours)

**Objective:** Setup AgentDB learning infrastructure with environment configuration

**Agent:** ml-developer

**Steps:**

1. **Install AgentDB Learning Module**
```bash
npm install agentdb-learning@latest
npm install @agentdb/rl-algorithms @agentdb/environments
```

2. **Initialize learning database**
```typescript
import { AgentDB, LearningPlugin } from 'agentdb-learning';

const learningDB = new AgentDB({
  name: 'rl-training-db',
  dimensions: 512, // State embedding dimension
  learning: {
    enabled: true,
    persistExperience: true,
    replayBufferSize: 100000
  }
});

await learningDB.initialize();

// Create learning plugin
const learningPlugin = new LearningPlugin({
  database: learningDB,
  algorithms: ['q-learning', 'dqn', 'ppo', 'actor-critic'],
  config: {
    batchSize: 64,
    learningRate: 0.001,

    bounds: [[0, 10], [0, 10]]
  },
  actionSpace: {
    type: 'discrete',
    actions: ['up', 'down', 'left', 'right']
  },
  rewardFunction: (state, action, nextState) => {
    // Distance to goal reward

      Math.pow(nextState[0] - 9, 2) +
      Math.pow(nextState[1] - 9, 2)
    );
    return -goalDistance + (goalDistance === 0 ? 100 : 0);
  },
  terminalCondition: (state) => {
    return state[0] === 9 && state[1] === 9; // Reached goal
  }
});

```typescript
async function trainAgent() {
  console.log('Starting RL training...');

  const trainingStats = {
    episodes: [],
    totalReward: [],
    episodeLength: [],
    loss: [],
    explorationRate: []
  };

  for (let episode = 0; episode < trainingConfig.episodes; episode++) {
    let state = await environment.reset();
    let episodeReward = 0;
    let episodeLength = 0;
    let episodeLoss = 0;

    for (let step = 0; step < trainingConfig.stepsPerEpisode; step++) {
      // Select action
      const action = await dqnAgent.selectAction(state, {
        explore: true
      });

      // Execute action
      const { nextState, reward, done } = await environment.step(action);

      // Store experience
      await dqnAgent.storeExperience({
        state,
        action,
        reward,
        nextState,
        done
      });

      // Train if enough experiences
      if (dqnAgent.canTrain()) {
        const loss = await dqnAgent.train();
        episodeLoss += loss;
      }

      episodeReward += reward;
      episodeLength += 1;
      state = nextState;

      if (done) break;
    }

    // Update target network
    if (episode % trainingConfig.targetUpdateFrequency === 0) {
      await dqnAgent.updateTargetNetwork();
    }

    // Decay exploration
    dqnAgent.decayExploration();

    // Log progress
    trainingStats.episodes.push(episode);
    trainingStats.totalReward.push(episodeReward);
    trainingStats.episodeLength.push(episodeLength);
    trainingStats.loss.push(episodeLoss / episodeLength);
    trainingStats.explorationRate.push(dqnAgent.getExplorationRate());

    if (episode % 100 === 0) {
      console.log(`Episode ${episode}:`, {
        reward: episodeReward.toFixed(2),
        length: episodeLength,
        loss: (episodeLoss / episodeLength).toFixed(4),
        epsilon: dqnAgent.getExplorationRate().toFixed(3)
      });
    }

    // Save checkpoint
    if (episode % trainingConfig.saveFrequency === 0) {
      await dqnAgent.save(`checkpoint-${episode}`);
    }

    // Evaluate
    if (episode % trainingConfig.evalFrequency === 0) {
      const evalReward = await evaluateAgent(dqnAgent, environment);
      console.log(`Evaluation at episode ${episode}: ${evalReward.toFixed(2)}`);
    }

    // Early stopping
    if (checkEarlyStopping(trainingStats, episode)) {
      console.log('Early stopping triggered');
      break;
    }
  }

  return trainingStats;
}

const trainingStats = await trainAgent();
```

2. **Monitor training progress**
```typescript
monitor.on('training-update', (stats) => {
  // Calculate moving averages
  const window = 100;
  const recentRewards = stats.totalReward.slice(-window);
  const avgReward = recentRewards.reduce((a, b) => a + b, 0) / recentRewards.length;

  // Store metrics
  agentDB.memory.store('agentdb/learning/training-progress', {
    episode: stats.episodes[stats.episodes.length - 1],
    avgReward: avgReward,
    explorationRate: stats.explorationRate[stats.explorationRate.length - 1],
    timestamp: Date.now()
  });

  // Plot learning curve (if visualization enabled)
  if (monitor.visualization) {
    monitor.plot('reward-curve', stats.episodes, stats.totalReward);
    monitor.plot('loss-curve', stats.episodes, stats.loss);
  }
});
```

3. **Handle convergence**
```typescript
function checkConvergence(stats, windowSize = 100, threshold = 0.01) {
  if (stats.totalReward.length < windowSize * 2) {
    return false;
  }

  const recent = stats.totalReward.slice(-windowSize);
  const previous = stats.totalReward.slice(-windowSize * 2, -windowSize);

  const recentAvg = recent.reduce((a, b) => a + b, 0) / recent.length;
  const previousAvg = previous.reduce((a, b) => a + b, 0) / previous.length;

  const improvement = (recentAvg - previousAvg) / Math.abs(previousAvg);

  return improvement < threshold;
}
```

4. **Save trained model**
```typescript
await dqnAgent.save('trained-agent-final', {
  includeReplayBuffer: false,
  includeOptimizer: false,
  metadata: {
    trainingStats: trainingStats,
    hyperparameters: hyperparameters,
    finalReward: trainingStats.totalReward[trainingStats.totalReward.length - 1]
  }
});

console.log('Training complete. Model saved.');
```

**Memory Pattern:**
```typescript
await agentDB.memory.store('agentdb/learning/training-results', {
  algorithm: 'dqn',
  episodes: trainingStats.episodes.length,
  finalReward: trainingStats.totalReward[trainingStats.totalReward.length - 1],
  converged: checkConvergence(trainingStats),
  modelPath: 'trained-agent-final',

});
```

**Validation:**

  const results = {
    rewards: [],
    episodeLengths: [],
    successRate: 0
  };

  for (let i = 0; i < numEpisodes; i++) {
    let state = await env.reset();
    let episodeReward = 0;
    let episodeLength = 0;
    let success = false;

    for (let step = 0; step < 1000; step++) {
      const action = await agent.selectAction(state, { explore: false });
      const { nextState, reward, done } = await env.step(action);

      episodeReward += reward;
      episodeLength += 1;
      state = nextState;

      if (done) {
        success = env.isSuccessful(state);
        break;
      }
    }

    results.rewards.push(episodeReward);
    results.episodeLengths.push(episodeLength);
    if (success) results.successRate += 1;
  }

  results.successRate /= numEpisodes;

  return {
    meanReward: results.rewards.reduce((a, b) => a + b, 0) / results.rewards.length,
    stdReward: calculateStd(results.rewards),
    meanLength: results.episodeLengths.reduce((a, b) => a + b, 0) / results.episodeLengths.length,
    successRate: results.successRate,
    results: results
  };
}

const evalResults = await evaluateAgent(trainedAgent, environment, 100);
console.log('Evaluation results:', evalResults);
```

3. **Compare with baseline**
```typescript
// Random policy baseline
const randomAgent = learningPlugin.createAgent({ algorithm: 'random' });
const randomResults = await evaluateAgent(randomAgent, environment, 100);

// Calculate improvement
const improvement = {
  rewardImprovement: (evalResults.meanReward - randomResults.meanReward) / Math.abs(randomResults.meanReward),
  lengthImprovement: (randomResults.meanLength - evalResults.meanLength) / randomResults.meanLength,
  successImprovement: evalResults.successRate - randomResults.successRate
};

console.log('Improvement over random:', improvement);
```

4. **Run comprehensive benchmarks**
```typescript
const benchmarks = {
  performanceMetrics: {
    meanReward: evalResults.meanReward,
    stdReward: evalResults.stdReward,
    successRate: evalResults.successRate,
    meanEpisodeLength: evalResults.meanLength
  },
  algorithmComparison: {
    dqn: evalResults,
    random: randomResults,
    improvement: improvement
  },
  inferenceTiming: {
    actionSelection: 0,
    totalEpisode: 0
  }
};

// Measure inference speed
const timingTrials = 1000;
const startTime = performance.now();
for (let i = 0; i < timingTrials; i++) {
  const state = await environment.randomState();
  await trainedAgent.selectAction(state, { explore: false });
}
const endTime = performance.now();
benchmarks.inferenceTiming.actionSelection = (endTime - startTime) / timingTrials;

await agentDB.memory.store('agentdb/learning/benchmarks', benchmarks);
```

```typescript
await agentDB.memory.store('agentdb/learning/validation', {
  evaluated: true,
  meanReward: evalResults.meanReward,
  successRate: evalResults.successRate,
  improvement: improvement,
  timestamp: Date.now()
});
```

**Validation:**
- Evaluation completed (100 episodes)
- Mean reward exceeds threshold
- Success rate acceptable
- Improvement over baseline demonstrated

### Phase 5: Deploy Trained Agents (1-2 hours)

  includeMetadata: true
});
```

2. **Create inference API**
```typescript
import express from 'express';

const app = express();
app.use(express.json());

// Load production agent
const productionAgent = await learningPlugin.loadAgent('production-agent');

app.post('/api/predict', async (req, res) => {
  try {
    const { state } = req.body;

    const action = await productionAgent.selectAction(state, {
      explore: false,
      returnProbabilities: true
    });

    res.json({
      action: action.action,
      probabilities: action.probabilities,
      confidence: action.confidence
    });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

app.listen(3000, () => {
  console.log('RL agent API running on port 3000');
});
```

3. **Setup monitoring**

import { ProductionMonitor } from '@agentdb/monitoring';

const prodMonitor = new ProductionMonitor({
  agent: productionAgent,
  metrics: ['inference-latency', 'action-distribution', 'reward-feedback'],
  alerting: {
    latencyThreshold: 100, // ms
    anomalyDetection: true
  }
});

await prodMonitor.start();
```

      ]
    }
  ]
};

This skill operates using AgentDB's npm package and API only. No additional MCP servers required.

All AgentDB learning plugin operations are performed through:
- npm CLI: `npx agentdb@latest create-plugin`
- TypeScript/JavaScript API: `import { AgentDB, LearningPlugin } from 'agentdb-learning'`

## Core Principles

AgentDB Reinforcement Learning Training operates on 3 fundamental principles:

### Principle 1: Experience Replay - Learn from Past Mistakes Without Catastrophic Forgetting

Naive online learning suffers from correlation bias (agent learns from consecutive similar experiences) and catastrophic forgetting (new experiences overwrite old knowledge). Prioritized experience replay stores diverse experiences in a buffer, samples uniformly to break correlations, and prioritizes high-error transitions to focus learning on difficult scenarios.

In practice:
- Maintain replay buffer with 100K+ experiences to ensure diverse sampling across state space
- Use prioritized replay (alpha=0.6) to oversample transitions with high TD-error, accelerating convergence 2-3x
- Apply importance sampling correction (beta=0.4->1.0) to prevent bias from non-uniform sampling
- Start training only after 1000+ warm-up experiences to ensure sufficient diversity

### Principle 2: Exploration-Exploitation Balance - Decay Epsilon to Shift from Discovery to Refinement

The exploration-exploitation dilemma is fundamental to RL: explore too much and waste time on suboptimal actions, exploit too much and miss better strategies. Epsilon-greedy with decay starts high (explore aggressively to map state space) and decays toward zero (exploit learned policy once confident).

In practice:
- Initialize epsilon=1.0 to ensure comprehensive state space exploration in early episodes
- Decay epsilon geometrically (multiply by 0.995 each episode) to smoothly transition from exploration to exploitation
- Set epsilon_min=0.01 to maintain 1% exploration indefinitely, preventing policy stagnation from environment changes
- Monitor reward variance - high variance indicates insufficient exploration, consider slower decay

### Principle 3: Target Network Stabilization - Decouple Policy from Value Estimation

Q-learning suffers from instability when the target (expected future reward) shifts while training. Using the same network for both action selection and target computation creates a moving target problem. Target networks freeze value estimates periodically, stabilizing training and improving convergence reliability.

In practice:
- Update target network every 1000 training steps (hard update) or use soft updates (tau=0.001) every step
- Soft updates provide smoother convergence for continuous control tasks (robotics, game AI)
- Hard updates work better for discrete action spaces with sparse rewards
- Monitor TD-error convergence - diverging errors indicate target network update frequency needs adjustment

## Common Anti-Patterns

| Anti-Pattern | Problem | Solution |
|--------------|---------|----------|
| **Reward Hacking - Agent Finds Unintended Policy Shortcuts** | Poorly designed reward functions incentivize agents to exploit loopholes rather than solve the intended task. Classic example: agent learns to pause game indefinitely to avoid losing instead of playing well. | Use shaped rewards with multiple components (task completion + efficiency + constraints). Validate reward function with adversarial testing - manually identify shortcuts and penalize them. Prefer sparse terminal rewards over dense step rewards when task definition is clear. |
| **Training Convergence Blindness - Run Fixed Episode Count Without Monitoring** | Training for arbitrary 10K episodes wastes compute if convergence happens at 3K or fails to converge at all. Agents either plateau early or train indefinitely without improvement. | Implement early stopping with patience threshold (stop if no improvement in 500 episodes). Monitor moving average reward over 100-episode window. Track loss curves alongside rewards - diverging loss indicates hyperparameter tuning needed before continuing training. |
| **Hyperparameter Lottery - Use Default Values Without Task-Specific Tuning** | RL algorithms are notoriously sensitive to hyperparameters. Default learning_rate=0.001 may be 10x too high for high-dimensional state spaces or 10x too low for simple tasks. | Start with baseline hyperparameters from algorithm papers for similar task domains. Run hyperparameter sweeps on key parameters (learning_rate, discount_factor, exploration_rate) using small-scale experiments (1K episodes).

## Conclusion

AgentDB Reinforcement Learning Training provides a production-ready framework for training autonomous agents across 9 RL algorithms, from classic Q-Learning to state-of-the-art Decision Transformers. The 5-phase SOP systematically guides you from environment initialization and algorithm configuration through training iterations, performance validation, and production deployment, with comprehensive monitoring and benchmarking at each stage. By integrating experience replay, exploration-exploitation balancing, and target network stabilization, the framework implements proven RL best practices that accelerate convergence and improve final policy quality.

This skill is essential when building self-learning agents for game AI, robotics control, resource optimization, or any domain where optimal behavior must be discovered through trial-and-error rather than explicitly programmed. The key differentiator is systematic validation - rather than blindly training for arbitrary episode counts, the framework monitors convergence, validates against baselines, and implements early stopping to prevent wasted computation. The deployment pipeline ensures trained policies are properly exported, optimized (quantization, format conversion), and monitored in production with latency and action distribution tracking.

The choice of RL algorithm matters critically. Q-Learning and SARSA suit discrete action spaces with full observability. DQN scales to high-dimensional state spaces (images, sensor data). Policy gradient methods (PPO, A2C) handle continuous control and partial observability. Decision Transformers enable offline RL from logged data without environment interaction. The framework provides all 9 algorithms with unified interfaces, allowing rapid experimentation to find the optimal approach for your specific task complexity, state/action space characteristics, and data availability constraints. With proper validation against baselines and comprehensive benchmarking, you can confidently deploy RL agents that genuinely learn and improve rather than memorizing fixed policies.
