Basher83 Agent Auditor Multi Agent Composition

Multi-Agent Composition

Master Claude Code's components, patterns, and principles to build effective agentic systems.

When to Use This Knowledge

Use this knowledge when:

• Learning Claude Code - Understanding what each component does
• Making architectural decisions - Choosing Skills vs Sub-Agents vs MCP vs Slash Commands
• Building custom solutions - Creating specialized agents or orchestration systems
• Scaling agentic workflows - Moving from single agents to multi-agent orchestration
• Debugging issues - Understanding why components behave certain ways
• Adding observability - Implementing hooks for monitoring and control

Quick Reference

The Core 4 Framework

Every agent is built on these four elements:

1. Context - What information does the agent have?
2. Model - What capabilities does the model provide?
3. Prompt - What instruction are you giving?
4. Tools - What actions can the agent take?

"Everything comes down to just four pieces. If you understand these, you will win."

Component Overview

Composition Hierarchy

Skills (Top Layer)
  ├─→ Can use: Sub-Agents, Slash Commands, MCP Servers, Other Skills
  └─→ Purpose: Orchestrate primitives for repeatable workflows

Sub-Agents (Execution Layer)
  ├─→ Can use: Slash Commands, Skills
  └─→ Cannot nest other Sub-Agents

Slash Commands (Primitive Layer)
  └─→ The fundamental building block

MCP Servers (Integration Layer)
  └─→ Connect external systems

Golden Rules

1. Always start with prompts - Master the primitive first
2. "Parallel" = Sub-Agents - Nothing else supports parallel execution
3. External = MCP, Internal = Skills - Clear separation of concerns
4. One-off = Slash Command - Don't over-engineer
5. Repeat + Management = Skill - Only scale when needed
6. Don't convert all slash commands to skills - Huge mistake
7. Context, Model, Prompt, Tools - Never forget the foundation

Documentation Structure

This skill uses progressive disclosure. Start here, then navigate to specific topics as needed.

Reference Documentation

Architecture fundamentals - What each component is and how they work

• architecture.md - Component definitions, capabilities, restrictions
• core-4-framework.md - Deep dive into Context, Model, Prompt, Tools

Implementation Patterns

How to use components effectively - Decision-making and implementation

• decision-framework.md - When to use Skills vs Sub-Agents vs MCP vs Slash Commands
• hooks-in-composition.md - Implementing hooks for observability and control
• orchestrator-pattern.md - Multi-agent orchestration at scale
• context-management.md - Managing context across agents
• context-in-composition.md - Context handling in multi-agent systems

Anti-Patterns

Common mistakes to avoid

• common-mistakes.md - Converting all slash commands to skills, using skills for one-offs, context explosion, and more

Examples

Real-world case studies and progression paths

• progression-example.md - Evolution from prompt → sub-agent → skill (work tree manager example)
• case-studies.md - Scout-builder patterns, orchestration workflows, multi-agent systems

Workflows

Visual guides and decision trees

• decision-tree.md - Decision trees, mindmaps, and visual guides for choosing components

Getting Started

If you're new to Claude Code

1. Start with reference/architecture.md to understand components
2. Read reference/core-4-framework.md to grasp the foundation
3. Use patterns/decision-framework.md to make your first architectural choice
4. Check anti-patterns/common-mistakes.md to avoid pitfalls

If you're making an architectural decision

1. Open patterns/decision-framework.md
2. Follow the decision tree to identify the right component
3. Review the specific component in reference/architecture.md
4. Check examples/ for similar use cases

If you're adding observability

1. Read patterns/hooks-in-composition.md to understand available hooks and implementation
2. Use isolated scripts pattern (UV, bun, or shell)

If you're scaling to multi-agent orchestration

1. Ensure you've mastered custom agents first
2. Read patterns/orchestrator-pattern.md
3. Study examples/case-studies.md
4. Review patterns/context-management.md

Key Principles from the Field

Prompts Are the Primitive

"Do not give away the prompt. The prompt is the fundamental unit of knowledge work and of programming. If you don't know how to build and manage prompts, you will lose."

Everything is prompts in the end. Master slash commands before skills. Have a strong bias toward slash commands.

Skills Are Compositional, Not Replacements

"It is very clear this does not replace any existing feature or capability. It is a higher compositional level."

Skills orchestrate other components; they don't replace them. Don't convert all your slash commands to skills—that's a huge mistake.

Observability is Everything

"When it comes to agentic coding, observability is everything. How well you can observe, iterate, and improve your agentic system is going to be a massive differentiating factor."

If you can't measure it, you can't improve it. If you can't measure it, you can't scale it.

Context Window Protection

"200k context window is plenty. You're just stuffing a single agent with too much work. Don't force your agent to context switch."

Create focused agents with single purposes. Delete them when done. Treat agents as temporary, deletable resources.

The Agentic Engineering Progression

Level 1: Base agents       → Use agents out of the box
Level 2: Better agents     → Customize prompts and workflows
Level 3: More agents       → Run multiple agents
Level 4: Custom agents     → Build specialized solutions
Level 5: Orchestration     → Manage fleets of agents
