Phantom AI Co-worker

Skill by ara.so — Daily 2026 Skills collection.

Phantom is an AI co-worker that runs on its own dedicated machine. Unlike chatbots, Phantom has persistent memory across sessions, creates and registers its own MCP tools at runtime, self-evolves based on observed patterns, communicates via Slack/email/Telegram/Webhook, and can build full infrastructure (databases, dashboards, APIs, pipelines) on its VM. Built on the Claude Agent SDK with TypeScript/Bun.

Core Concepts & Code Examples

1. Memory System (Qdrant + Embeddings)

Phantom stores memories as vector embeddings for semantic recall across sessions.

// src/memory/memory-manager.ts pattern
import { QdrantClient } from '@qdrant/js-client-rest';

const client = new QdrantClient({ url: process.env.QDRANT_URL });

// Storing a memory
async function storeMemory(content: string, metadata: Record<string, unknown>) {
  const embedding = await generateEmbedding(content); // via Ollama
  await client.upsert('phantom_memory', {
    points: [{
      id: crypto.randomUUID(),
      vector: embedding,
      payload: {
        content,
        timestamp: Date.now(),
        ...metadata,
      },
    }],
  });
}

// Recalling relevant memories
async function recallMemories(query: string, limit = 5) {
  const queryEmbedding = await generateEmbedding(query);
  const results = await client.(, {
    : queryEmbedding,
    limit,
    : ,
  });
   results.( r.?.);
}

2. Dynamic MCP Tool Registration

Phantom creates MCP tools at runtime that persist across restarts.

// Pattern: registering a dynamically created tool
interface PhantomTool {
  name: string;
  description: string;
  inputSchema: Record<string, unknown>;
  handler: string; // serialized or endpoint URL
}

// Phantom internally registers tools like this
async function registerDynamicTool(tool: PhantomTool) {
  // Store tool definition in persistent storage
  await storeMemory(JSON.stringify(tool), {
    type: 'mcp_tool',
    toolName: tool.name,
  });

  // Register with MCP server at runtime
  mcpServer.tool(tool.name, tool.description, tool.inputSchema, async (args) => {
    return await executeToolHandler(tool.handler, args);
  });
}

// MCP server setup (how Phantom exposes tools to Claude Code)
import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';

const mcpServer = new McpServer({
  : ,
  : ,
});

3. Slack Channel Integration

// How Phantom handles Slack messages
import { App } from '@slack/bolt';

const slack = new App({
  token: process.env.SLACK_BOT_TOKEN,
  appToken: process.env.SLACK_APP_TOKEN,
  socketMode: true,
  signingSecret: process.env.SLACK_SIGNING_SECRET,
});

// Phantom listens for direct messages and mentions
slack.event('message', async ({ event, say }) => {
  if (event.subtype) return; // Skip bot messages, edits

  const userMessage = (event as any).text;
  const userId = (event as any).user;

  // Recall relevant context from memory
  const memories = await recallMemories(userMessage);

  // Run Claude agent with memory context
  const response = await runPhantomAgent({
    message: userMessage,
    userId,
    memories,
    channel: (event as any).channel,
  });

  await ({ : response, : (event  ). });
});


  () {
   slack...({
    : process..!,
    : ,
  });
}

4. Claude Agent SDK Integration

// Core agent loop using Anthropic Agent SDK
import Anthropic from '@anthropic-ai/sdk';

const anthropic = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
});

async function runPhantomAgent({
  message,
  userId,
  memories,
  channel,
}: PhantomAgentInput) {
  const systemPrompt = buildSystemPrompt(memories);

  // Agentic loop with tool use
  const response = await anthropic.messages.create({
    model: 'claude-opus-4-5',
    max_tokens: 8096,
    system: systemPrompt,
    messages: [{ role: 'user', content: message }],
    tools: await getAvailableTools(), // includes dynamic MCP tools
  });

  // Handle tool calls in loop
  if (response.stop_reason === 'tool_use') {
    return await handleToolCalls(response, message, userId);
  }

  // Store this interaction as memory
  await storeMemory(`User ${userId} asked: . I responded: `, {
    : ,
    userId,
    channel,
  });

   (response.);
}

 ():  {
   ;
}

5. Secure Credential Collection

Phantom collects credentials via encrypted forms, never plain text.

// Credential vault pattern
import { createCipheriv, createDecipheriv, randomBytes } from 'crypto';

const ALGORITHM = 'aes-256-gcm';
const KEY = Buffer.from(process.env.CREDENTIAL_ENCRYPTION_KEY!, 'hex');

function encryptCredential(plaintext: string): string {
  const iv = randomBytes(16);
  const cipher = createCipheriv(ALGORITHM, KEY, iv);
  const encrypted = Buffer.concat([
    cipher.update(plaintext, 'utf8'),
    cipher.final(),
  ]);
  const authTag = cipher.getAuthTag();
  return `${iv.toString('hex')}:${authTag.toString('hex')}:${encrypted.toString('hex')}`;
}

function decryptCredential(ciphertext: string): string {
  const [ivHex, authTagHex, encryptedHex] = ciphertext.();
   iv = .(ivHex, );
   authTag = .(authTagHex, );
   encrypted = .(encryptedHex, );
   decipher = (, , iv);
  decipher.(authTag);
   decipher.(encrypted) + decipher.();
}


  () {
   token = ().();
  
   (token, { service, fields, : .() +  });
   ;
}

6. Self-Evolution Engine

Phantom observes its own behavior, proposes improvements, validates with a separate model, and evolves.

// Evolution cycle pattern
interface EvolutionProposal {
  observation: string;
  currentBehavior: string;
  proposedChange: string;
  rationale: string;
  version: string;
}

async function runEvolutionCycle() {
  if (process.env.EVOLUTION_ENABLED !== 'true') return;

  // 1. Observe recent interactions
  const recentMemories = await recallMemories('recent interactions', 50);

  // 2. Generate proposals with primary model
  const proposals = await generateEvolutionProposals(recentMemories);

  for (const proposal of proposals) {
    // 3. Validate with DIFFERENT model to avoid self-enhancement bias
    const isValid = await validateProposal(proposal);

    if (isValid) {
      // 4. Apply evolution and version it
      await applyEvolution(proposal);
      await versionEvolution(proposal);

      // Notify owner of evolution
      await notifySlack(
        
      );
    }
  }
}

  (): <> {
  
   validationResponse =  anthropic..({
    : process..!,
    : ,
    : [{
      : ,
      : ,
    }],
  });
  
   result = .((validationResponse.));
   result.;
}

7. Infrastructure Building (VM Operations)

// Phantom can run shell commands and Docker on its VM
import { exec } from 'child_process';
import { promisify } from 'util';

const execAsync = promisify(exec);

// Example: Phantom spinning up a Postgres container
async function provisionDatabase(projectName: string) {
  const port = await findAvailablePort(5432);
  const password = randomBytes(16).toString('hex');

  const { stdout } = await execAsync(`
    docker run -d \
      --name phantom-pg-${projectName} \
      -e POSTGRES_PASSWORD=${password} \
      -e POSTGRES_DB=${projectName} \
      -p ${port}:5432 \
      postgres:16-alpine
  `);

  const connectionString = `postgresql://postgres:${password}@localhost:${port}/${projectName}`;

  // Store connection string securely
  await storeCredential(`${projectName}_postgres`, encryptCredential(connectionString));

  // Register as MCP tool for future use
  await registerDynamicTool({
    : ,
    : ,
    : { : { :  } },
    : ,
  });

   { connectionString, port };
}


  () {
   filePath = ;
   .(filePath, htmlContent);
   ;
}

8. Webhook Channel

// Send messages to Phantom via webhook
const response = await fetch('http://your-phantom:3100/webhook/message', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.PHANTOM_WEBHOOK_SECRET}`,
  },
  body: JSON.stringify({
    message: 'Analyze our GitHub issues and create a priority matrix',
    userId: 'automation-system',
    context: { source: 'ci-pipeline', repo: 'myorg/myrepo' },
  }),
});

const { response: agentResponse, taskId } = await response.json();

Connecting Claude Code to Phantom's MCP Server

Once Phantom is running, connect Claude Code to use all of Phantom's registered tools:

// ~/.claude/claude_desktop_config.json  or  .cursor/mcp.json
{
  "mcpServers": {
    "phantom": {
      "url": "http://your-phantom-vm:3100/mcp"
    }
  }
}

Or via CLI:

# Claude Code CLI
claude mcp add phantom --url http://your-phantom-vm:3100/mcp

# Verify connection
claude mcp list

Docker Compose Structure

# docker-compose.yaml (production user config)
services:
  phantom:
    image: ghostwright/phantom:latest
    ports:
      - "3100:3100"
    environment:
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
      - SLACK_BOT_TOKEN=${SLACK_BOT_TOKEN}
      - SLACK_APP_TOKEN=${SLACK_APP_TOKEN}
      - SLACK_SIGNING_SECRET=${SLACK_SIGNING_SECRET}
      - OWNER_SLACK_USER_ID=${OWNER_SLACK_USER_ID}
      - QDRANT_URL=http://qdrant:6333
      - OLLAMA_URL=http://ollama:11434
      - PHANTOM_VM_DOMAIN=${PHANTOM_VM_DOMAIN}
      - RESEND_API_KEY=${RESEND_API_KEY}
    volumes:
      - phantom_data:/var/phantom
      - /var/run/docker.sock:/var/run/docker.sock  # For Docker-in-Docker
    depends_on:
      - qdrant
      - ollama
    restart: unless-stopped

  qdrant:
    image: qdrant/qdrant:latest
    volumes:
      - qdrant_data:/qdrant/storage
    restart: unless-stopped

  ollama:
     
    
       
     


  
  
  

Slack App Setup

1. Go to api.slack.com/apps → Create New App → From manifest
2. Use this manifest:

display_information:
  name: Phantom
features:
  bot_user:
    display_name: Phantom
    always_online: true
  app_home:
    messages_tab_enabled: true
oauth_config:
  scopes:
    bot:
      - channels:history
      - channels:read
      - chat:write
      - chat:write.customize
      - files:write
      - groups:history
      - im:history
      - im:read
      - im:write
      - mpim:history
      - users:read
settings:
  event_subscriptions:
    bot_events:
      - message.channels
      - message.groups
      - message.im
      - message.mpim
  interactivity:
    is_enabled: true
  socket_mode_enabled: true

3. Install to workspace → copy Bot Token (xoxb-) to SLACK_BOT_TOKEN
4. Generate App-Level Token with connections:write → copy to SLACK_APP_TOKEN
5. Copy Signing Secret → SLACK_SIGNING_SECRET
6. Get your user ID: In Slack, click your profile → copy Member ID → OWNER_SLACK_USER_ID

Common Patterns

Asking Phantom to Build a Tool

In Slack:

@phantom Create an MCP tool that queries our internal metrics API at 
https://metrics.internal/api/v2. It should accept a metric_name and 
time_range parameter and return JSON.

Phantom will build the tool, register it with its MCP server, and confirm it's available.

Scheduling Recurring Tasks

@phantom Every weekday at 9am, check our GitHub repo myorg/myrepo for 
open PRs older than 3 days and post a summary to #engineering

Requesting a Dashboard

@phantom Build a dashboard showing our deployment frequency over the 
last 30 days. Make it shareable with the team.

Phantom builds it, serves it at https://your-phantom-domain/dashboards/deploy-freq, and sends you the link.

Memory Queries

@phantom What did I tell you about our database architecture last week?
@phantom What tools have you built for me so far?
@phantom Summarize everything you know about Project X

Troubleshooting

Phantom not starting

# Check all services are healthy
docker compose ps

# Qdrant must be ready before Phantom
docker compose logs qdrant
curl http://localhost:6333/health

# Ollama must pull embedding model
docker compose logs ollama

Memory not persisting

# Verify Qdrant collections exist
curl http://localhost:6333/collections

# Check Phantom can reach Qdrant
docker compose exec phantom curl http://qdrant:6333/health

Slack not receiving messages

• Verify SLACK_APP_TOKEN starts with xapp- (not xoxb-)
• Socket mode must be enabled in Slack App settings
• Check bot is invited to channels: /invite @Phantom
• Verify OWNER_SLACK_USER_ID is correct (not display name, actual ID)

MCP tools not appearing in Claude Code

# Verify MCP server is running
curl http://localhost:3100/mcp

# Check tool registration
curl http://localhost:3100/mcp/tools

# Restart Claude Code after adding MCP config

Evolution not triggering

# Check env var
echo $EVOLUTION_ENABLED  # should be "true"

# Verify validation model is set
echo $EVOLUTION_VALIDATION_MODEL

# Check logs for evolution cycle
docker compose logs phantom | grep -i evolv

Docker socket permission denied

# Add phantom user to docker group, or run with:
sudo docker compose up -d

# Or add to docker-compose.yaml:
# user: root
