Claude Custom Subagents (Build Your Own AI Workers) | CampusX

This video dives into Custom Subagents in Claude Code and shows how to go beyond built-in agents by creating specialized, task-specific workflows. It starts by explaining why custom subagents are needed, especially when built-in agents cannot follow project-specific rules (like security audits or testing standards). Then it breaks down how subagents are created using markdown files, YAML configuration, tools, and system prompts. The video also covers how to trigger subagents (automatically and manually using slash commands) and integrates everything into a real project. A full workflow is built using multiple subagents for testing, code review, and validation—demonstrating how to create scalable, modular AI development pipelines. 📱 Grow with us: CampusX' LinkedIn:   / campusx-official   CampusX on Instagram for daily tips:   / campusx.official   My LinkedIn:   / nitish-singh-03412789   Discord:   / discord   E-mail us at [email protected] Chapters 00:00:00 - Introduction & Recap of Subagents 00:01:14 - Why Custom Subagents are Needed (vs Built-in) 00:02:26 - Real Example: Security Audit Use Case 00:04:17 - Concept: Specialized vs Generic Agents 00:05:47 - How to Create Custom Subagents (Core Idea) 00:06:30 - Subagent Structure (Markdown + YAML + Instructions) 00:08:10 - Project vs Personal Subagents 00:09:00 - How Subagents are Triggered (Auto vs Manual) 00:10:00 - Using Slash Commands to Trigger Subagents 00:10:48 - Project Setup & Feature Goal (Profile Page Enhancement) 00:12:00 - Spec-Driven Workflow Recap 00:14:00 - New Workflow: Testing + Code Review Added 00:15:00 - Designing Subagent Workflow (Testing Pipeline) 00:15:30 - Test Writer + Test Runner Subagents 00:16:30 - Code Review Subagents (Security + Quality) 00:18:00 - Practical: Creating Custom Subagents 00:19:00 - Creating Test Writer Subagent 00:26:00 - Creating Test Runner Subagent 00:28:50 - Connecting Subagents via Slash Command
