The Four Real Barriers

01

Claude Code — The Real Usage

CLAUDE.md engineering, Hooks automation, custom slash commands, parallel sub-agents — these are the capabilities that actually create the gap.

CLAUDE.md Hooks Slash Commands Multi-Agent

02

MCP: Model Context Protocol

Give Claude sensors and actuators. Those who can build MCP Servers turn Claude into a company's intelligent hub. Everyone else pastes text.

03

Context Engineering

Prompt engineering is a 2023 concept. The real battle is designing layered information structures — system-level, session-level, immediate-level — three clear layers unlock a qualitative leap.
