Ein Agent Harness ist nicht Claude Code selbst. Es ist die Schicht drumherum, die Multi-Agent Workflows orchestriert, State Management handhabt, und Production-Ready macht.

Was ist ein Agent Harness?

Claude Code allein kann:

  • Eine Task abarbeiten
  • Eine Datei bearbeiten
  • Ein Shell-Kommando ausführen

Ein Harness kann:

  • 5+ Agents gleichzeitig coordinieren
  • State zwischen Agents synchronisieren
  • Fehler automatisch beheben
  • Git Branches isolieren
  • Test-Suites ausführen
  • Monitoring & Logging
  • Retry Logic

Common Patterns

Pattern 1: Analyst → Builder → Reviewer

// Everything Claude Code Config
const agents = [
  {
    name: "analyst",
    role: "Analyse Requirements & Design",
    skills: ["code-analysis", "architecture-review"]
  },
  {
    name: "builder",
    role: "Implementiert Code",
    skills: ["code-generation", "testing"]
  },
  {
    name: "reviewer",
    role: "Code Review & QA",
    skills: ["code-review", "security-scan"]
  }
];

// Workflow: analyst → builder → reviewer

Pattern 2: Parallel Workers + Coordinator

# Composio Framework
agents = [
  ParallelAgent("worker-1", tasks["module-a"]),
  ParallelAgent("worker-2", tasks["module-b"]),
  ParallelAgent("worker-3", tasks["module-c"]),
  SequentialAgent("coordinator", ["merge", "test", "deploy"])
]

Pattern 3: Slack-Driven

// Your Claude Engineer
slack.onMessage("@claude build feature X", () => {
  agent.run("Build feature X");
  // Posts to GitHub issues
  // Responds in Slack
});

Häufige Fehler

Fehler 1: Zu viele Agents für falschem Harness

  • Problem: 50 Agents mit Framework = Chaos
  • Lösung: Everything Claude Code oder Ruflo für Scale

Fehler 2: Kein State Management

  • Problem: Agents arbeiten aneinander vorbei
  • Lösung: Memory System wie in Everything Claude Code

Fehler 3: Credentials hardcoded

  • Problem: Git enthält API Keys
  • Lösung: Vault Integration (alle Harnesses unterstützen)

Monitoring & Debugging

Jeder Harness hat unterschiedliche Debugging-Tools:

Everything Claude Code:

node index.js --debug
# → Logs: Agent State, Memory, Tool Calls

Ruflo:

Dashboard: http://localhost:3000
→ Real-Time Agent Status, Resource Usage

Composio:

composio status
# → Parallel Agents, PR Status, Test Results
