What are subagents? Subagents are like focused teammates for your IDE Each one: - Has a specific purpose - Uses a separate context window - Can be limited to selected tools - Follows a custom system prompt It works independently and returns focused results.

Now let's build a team of sub agents and see them in actions. Here are 4 agents we're building: 1. Code-reviewer 2. Debugger 3. Data-scientist 4. Web-researcher Next we'll see detailed description for each one-by-one...👇

Here's a blueprint to create a subagent. Each has it's own: - context window - system prompt - tools and tasks Juts add them to .claude/agents/my_agent. md Check this out👇

1️⃣ Code reviewer This subagent reviews your code for quality, security, and maintainability. Can also do semantic search over the entire code base using Claude Index MCP by Ziliz (open-source) Check this out👇

Finally when done we asked out system to create a leaderboard for trending GitHub repos. Created a real time leaderboard in one shout! Automatically handled: - Web scraping logic - writing the code for ranking - creating the leaderboard Check this out👇

Best practices: - Start with Claude-generated agents, then customize - Focus each agent on a single task - Use detailed system prompts with examples - Restrict tool access for security - Write precise, action-oriented descriptions for better routing
