@hackproduct9: Most people explain an AI agent as “a model inside a loop.” 🤖🔁 Interviewers want the details: 🧠 Claude chooses the next action ⚙️ The SDK runtime executes it 🛡️ Permissions decide what is allowed 🪝 Hooks validate, block and observe from your application 📦 Tool results become the model’s next input 🏁 The loop stops when no tool calls remain—or a guardrail is hit The production-level answer: “The model decides. The runtime enforces.” 🎯 Save this before your next AI engineering interview. 📌 #ClaudeCode #ClaudeAgentSDK #AIAgents #AgenticAI #AIEngineering
