How I Use Qwen Code Slash Commands to Build Achu App

In this blog post, we will see how I use Qwen Code's slash commands and workflow strategies to build Achu my screenshot beautifier app without burning through tokens or losing context mid-session. If you haven't heard of Achu , it's a desktop app built with Electron + React + TypeScript. It does screenshot beautification, Privacy Guard (offline OCR redaction), Auto-Vibe (palette-extracted backgrounds), and an AI Bug Agent with GitHub integration. It's a side project I'm genuinely proud of, and Qwen Code has become my go-to agentic coding CLI for it. A developer shares their day-to-day workflow for using Qwen Code, an open-source agentic coding CLI, to build Achu, a desktop screenshot beautification app built with Electron, React, and TypeScript. The post covers how slash commands like /init, /plan, /compress, /remember, and /btw are used to manage context, reduce token costs, and maintain consistent output across sessions. The core approach centers on spec-driven planning through iterative /plan sessions before any code is written, combined with parallel subagents for independent tasks and strict context hygiene using /compress and /clear. Additional practices include pointing the model at library source code instead of documentation and using /remember to persist architectural decisions across sessions. This isn't a tutorial about what Qwen Code is. It's about how I actually use it day-to-day, the slash command tricks I rely on, and the discipline it takes to get real work done with an LLM in a terminal. It all started with Google Antigravity, but the 5 hours reset and weekly limits is killing my productivity and thinking flow. I had to switch to more affordable and open source model where I chose Qwen. Why Qwen Code? I've tried Claude Code, Gemini CLI, and a bunch of others. Qwen Code is open source, has excellent subagent support, a rich slash command system, and Qwen Max is genuinely strong at reasoning through complex TypeScript and Electron internals. My go-to
