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

Support This Project

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
