Summary

A user recounts wasting six months using Claude Code inefficiently, treating it merely as an autocomplete tool without leveraging its advanced features. This led to poor context management, repetitive setup, and unexpected costs. The author discovered a hidden control layer accessible via the "/" key, which provides specific commands to optimize interaction. Key among these is "/init", which scans a repository to generate a `CLAUDE.md` file. This file allows Claude to retain project context, including build commands, lint rules, and folder structure, across sessions, thereby preventing "amnesia" and improving overall efficiency and cost control. The article promises to detail 14 such commands that "changed everything."

Key takeaway

For AI Engineers or Software Engineers integrating Claude Code into their development workflow, understanding its command-line interface is crucial for efficiency and cost management. You should prioritize exploring the "/" commands, starting with "/init" for new projects, to establish persistent context and avoid repetitive setup. This approach will prevent unnecessary context window usage and provide better control over session costs, transforming Claude from a basic assistant into a powerful, context-aware coding partner.

Key insights

Leveraging Claude Code's specific "/" commands significantly enhances efficiency and context management, moving beyond basic autocomplete.

Principles

• Read documentation for advanced features.
• Proactive context setup prevents repetition.
• Understand tool's control layer.

Method

At project initiation, run "/init" to scan the repository and generate a `CLAUDE.md` file, establishing persistent project context for Claude Code sessions.

In practice

• Use "/init" for new project setup.
• Consult "/" menu for available commands.
