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

Prerequisites Python 3.10+ OpenAI API key (latest version) Familiarity with machine learning concepts What We're Building In this tutorial, we will embark on a journey to fine-tune a large language model (LLM) to cater to the specific communication needs of homeless shelters. By leveraging a bespoke dataset compiled from the Youth Spirit Artworks (YSA) Tiny House Empowerment Village website, we aim to create a model that can effectively assist in the nuances of communication required in such environments. The finished project will result in a model capable of generating contextually relevant and empathetic responses to inquiries typical within the homeless shelter community. This involves structuring data into a standardized question-and-answer format to enhance the training process, ensuring the model's outputs are aligned with the communication style and needs of the target audience. Setup and Installation To begin, we need to set up our development environment with the necessary tools and libraries for model fine-tuning. We'll be using Python along with the OpenAI library to interact with the LLMs. pip install openai pandas numpy Additionally, you'll need to configure environment variables to securely store your API keys. This ensures that sensitive information is not hardcoded into your scripts. .env file OPENAI_API_KEY=your_openai_api_key Step 1: Data Collection and Preparation The first step in fine-tuning our model involves collecting and
Coding agents draft specs, architecture docs, changelogs, and README updates in seconds — but a human still has to judge the quality of all that output. The bottleneck shift A year ago, the typical workflow was: you write a spec, you get comments, you revise, then you implement and get code review. Humans did most of the writing and coding. Now, agents produce first drafts of design docs, API references, runbooks, and onboarding guides — and they do it in seconds. Code implementation and code review can now be handled by agents, so those are no longer the bottleneck. What surfaced instead is the step right before: document review. A human has to read 2,000 lines of generated markdown and decide what's wrong. The writing part got dramatically faster. LLMs can assist with document review too, but compared to code implementation and code review, the human judgment required is still larger. This asymmetry compounds fast. Every agent-assisted project now has a stack of "needs human review" documents growing in a shared folder. If you're running multiple agent loops in parallel — one for the spec, one for the implementation plan, one for the test strategy — review becomes a pipeline stall. GitHub PRs remain the right tool when you need third-party review. But the step before that — the fast local self-review loop where you and your agent iterate on a draft — doesn't belong in a PR. Branching, diffing, and assigning reviewers is a lot of process for a first draft the agent wrote in seconds. Why prose feedback is lossy The most common workaround today is to have the agent read the document and then fix things based on natural-language feedback: "The error handling in section 3.2 is too vague — be specific about what happens on timeout." This looks reasonable. The agent reads it, searches for something about error handling, and makes a change. But several things go wrong: Position is ambiguous. If section 3.2 has three paragraphs about error handling, which one did the revie
The deployment should have taken a few minutes. The application was running, DNS was configured correctly, and the domain was already pointing to the server's public IP. Caddy was configured as a reverse proxy and was listening on ports 80 and 443. Every item on my deployment checklist appeared healthy. Yet every Let's Encrypt validation attempt kept failing. The error looked simple enough: authorization failed timeout during connect likely firewall problem At first, I believed it. I checked DNS resolution, verified firewall rules, confirmed that Caddy was listening on the expected ports, and made sure the application itself was reachable. Every check came back clean. That was the first clue that the problem might not be where the logs were pointing. The Obvious Things The first assumption was DNS. I verified that the domain resolved to the correct public IP. dig +short my-domain.com Everything looked correct. Next came the firewall. sudo ufw status Ports 80 and 443 were open. There were no unexpected deny rules, and nothing suggested inbound traffic was being blocked. Then I checked whether Caddy was actually listening. sudo ss -tulpn | grep -E ':80|:443' Again, everything looked normal. The application itself was healthy too. curl http://localhost:3001 returned a valid response. At this point I had checked most of the things engineers typically check when certificate validation fails. DNS looked good, the firewall looked good, the reverse proxy was healthy, and the application was running. Yet the validation errors continued. The Part That Sent Me In The Wrong Direction The error messages kept mentioning connectivity problems and possible firewall issues. That wording influenced my thinking more than it should have. I spent time investigating firewall rules, reverse proxy configuration, TLS settings, and domain configuration. Every new hypothesis felt reasonable, but none of them explained why local tests consistently succeeded while external validation continued
vibe citing: how KPMG used AI to write a report about AI and AI made them look like fools by t474-r0b07 There are companies that charge you to tell you how to use AI responsibly. KPMG is one of them. 250,000 employees. 138 countries. Decades advising governments and corporations on how to avoid costly mistakes. In October 2025 they published a report titled "Total Experience: Redefining Excellence in the Age of Agentic AI" . They wrote it with AI. The AI invented 88% of the sources. Nobody verified anything. They published it anyway. // what is "agentic AI" — because the title matters An agentic AI is not a chatbot. Not the assistant that answers your questions. It's a system that makes decisions and executes actions on its own, without a human approving each step. You give it an objective and it acts, corrects, moves forward. It's the product everyone in the tech sector was selling in 2025. KPMG was selling it too. That's why they needed a report proving their clients were already using it. Spoiler: they weren't. And the report invented it anyway. // the forensic analysis GPTZero — a company specialized in detecting AI-generated content — ran a full audit on the report. First: what is an AI hallucination, because the term is going to come up a lot. When a language model doesn't have the information you ask for, it doesn't say "I don't know." It generates a response that sounds correct. It invents with the same confidence it would use if it actually knew the truth. Perfect format. False content. No warning. That's a hallucination. Now the numbers from the KPMG report: TOTAL CITATIONS: 45 REAL CITATIONS: 5 INVENTED CITATIONS: 40 ACCURACY RATE: 11.1% 40 of 45 citations have invented titles, authors that don't exist, or sources that don't say what KPMG claimed they said. Half of the factual claims in the report are false or misattributed. A firm that charges for intellectual rigor published a document with 11% accuracy. // the organizations that read the report and sai
Few-shot learning with large language models is one of the most practical ways to steer model behavior without updating weights. By embedding task-specific examples directly into the prompt, developers can turn a general-purpose foundation model into a domain-specific classifier, parser, or reasoning engine. The technique relies on in-context learning, where the model infers patterns from exemplars rather than from gradient updates. Because it requires no training pipeline, few-shot prompting is ideal for rapid prototyping and production tasks where data volumes are too small for fine-tuning or where model weights must remain frozen. The Mechanics of In-Context Learning In-context learning is an emergent capability of transformer-based language models. During inference, the model attends to the full context window, using the provided examples as a dynamic prior. Each example adjusts the hidden-state activations for subsequent tokens, effectively conditioning the output distribution without any parameter change. Research suggests that the model locates latent task representations within its pretrained weight space and uses the few-shot examples to activate the appropriate subspace. The result is a flexible interface: change the examples, and the model adapts its behavior immediately. Zero-Shot, One-Shot, and Few-Shot Prompting These three patterns describe how much guidance you provide before the actual task input. Zero-shot: You describe the task in natural language with no examples. This works best for simple, well-known tasks that the model has seen frequently during pretraining. One-shot: You prepend a single example. This is often enough to communicate output format or tone. Few-shot: You prepend three to ten examples, sometimes more for complex schema extraction or multi-label classification. The marginal gain from each additional example typically diminishes, but for tasks with rigid output schemas, a larger set of exemplars can substantially improve consisten
