<!-- Auto-Update Notice -->
> This repository is automatically kept up to date. Every week, an AI agent researches the latest Claude, Anthropic, MCP, and AI news — then opens a PR with updates across all guides, skills, and templates. I review and merge it manually. You're always reading current information.

## Make Claude Code Behave Like a Senior Engineer
Reading this guide teaches you *what* to prompt. **[claude-kopitiam](https://github.com/ThamJiaHe/claude-kopitiam)** makes Claude *automatically act on it* — without you having to ask every time.
It's a companion config layer: 7 rules files that install into `~/.claude/rules/` and load on every Claude Code session.
| Without kopitiam | With kopitiam |
|---|---|
| Write Python — generic response | `router.md` auto-triggers `python-reviewer` |
| Start planning — Claude dives into code | Routes to `brainstorming` then `writing-plans` first |
| Touch auth or tokens — no safety net | `security.md` guards fire by default |
| Any commit message accepted | Conventional commits enforced automatically |
| Hit 85% context — silent degradation | `/save-session` + `/compact` discipline triggers |
```bash
git clone https://github.com/ThamJiaHe/claude-kopitiam
cd claude-kopitiam && bash INSTALL.sh
```

This guide is **free and always will be** — but keeping it accurate costs real money. Every week, an AI agent queries Perplexity to research the latest news, then uses Claude Opus to update every guide. That automation runs on API credits.
| What | Why it matters |
|---|---|
| **Perplexity API** | Powers the weekly internet research agent |
| **Anthropic API** | Claude Opus rewrites and updates the guides |
| **Weekly automation** | Keeps every section current as AI evolves fast |
