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.
This repo runs on API credits — every coffee keeps it alive and updated.
Perplexity + Anthropic APIs power the weekly research agent that keeps every guide current.
If this guide saved you time, a coffee goes a long way.

Make Claude Code Behave Like a Senior Engineer
Reading this guide teaches you what to prompt. 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 |
