This is the Day 1 companion exercise for the AI Path L1→L2 Upgrade Guide. Read Part 1 first, then come back here to practice. Today you do exactly one thing: run hello_api.py from Part 1 and see AI reply in your terminal. Prerequisites Complete these steps from Part 1 (skip if already done): Register a DeepSeek developer account (Part 1, “Register for API Accounts”) Get your API key and save it to a .env file (Part 1, “API Key Safety”) Install uv and Python 3.12 (Part 1, “Install Python”) Create a virtual environment and install dependencies (Part 1, “Create a Virtual Environment”) Confirm your project directory looks like this: ...

TL;DR: This is Part 1 of the “AI Path L1→L2 Upgrade Guide” series. Four parts total, one per week of practice. This article takes you from chat windows to APIs, automating your AI interactions through code, laying the foundation for batch processing and autonomous task-execution AI. Introduction: From “I Ask AI” to “Programs Ask AI” If you finished the L0→L1 graduation checklist, you might remember one line from the graduation post: “Register for an API account and use Python to print your first AI reply.” Today is that day. ...

The biggest obstacle to building a Prompt library isn’t the tool. It’s knowing how to organize it. Yesterday you picked 5 Prompts; today I’ll show you a complete real template. Directory Structure This structure uses the Markdown folder approach. You can copy it directly: prompt-library/ ├── writing/ │ ├── email.md │ ├── article-summary.md │ └── ... ├── analysis/ │ ├── data-interpretation.md │ ├── case-breakdown.md │ └── ... ├── daily/ │ ├── meeting-notes.md │ └── ... └── README.md (global notes) The record format for each Prompt: ...

Today’s Practice From your recent AI conversations (coding, writing, analysis), pick 5 prompts that actually worked well. Record them using the template from Part 4: Original Prompt + Effectiveness + Iteration. Where you record them doesn’t matter. A notes app, Notion, or a plain text file all work. Don’t overthink the tool. If you can’t find your chat history, spend 20 minutes creating 5 prompts you’ll definitely use at work. For example: “Check the edge cases in this code,” “Rewrite this technical article for beginners,” “Extract the 3 main issues from these 100 pieces of user feedback.” ...

📖 This is Part 4 of 5 in the “AI Path L0→L1 Upgrade Guide” series. Part 1: Understanding Your Tools · Part 2: From Vague Questions to Precise Instructions · Part 3: Turning AI Into Your Collaboration Partner · Part 4: Building Your Personal System · Part 5: Graduation & Next Steps Over three weeks you’ve picked up follow-up questions, context management, role-playing… the skills are piling up, and here’s the problem: how do you manage all these scattered abilities in one place? Week 4 is about exactly that: building a prompt library, choosing the right tools, and setting up knowledge management. Turning what you’ve learned into a personal system. ...

Yesterday’s discussion covered follow-up questions: three questions to dig out the hidden assumptions behind an AI answer. The catch is, you need to know what to ask. Some blind spots you simply can’t see from your own perspective. That’s when you give AI a different identity. The Devil’s Advocate Please act as a strict reviewer. Go through this plan point by point and identify every risk and weakness. Don’t hold back — the sharper, the better. ...

The previous post was about how long conversations drift. After writing it, I noticed something else: drift does not only happen after a conversation gets long. It can also happen inside any answer that looks complete. AI answers quickly, and its conclusions often sound smooth. But it rarely says upfront: what assumptions does this conclusion depend on? If those assumptions are not checked, I end up accepting them by default. Accept enough unchecked assumptions, and the later analysis may be built on the wrong foundation. ...

The previous exercise was to run a 15-turn conversation with AI, using progress summaries and new conversations as checkpoints. If you actually did it, you probably noticed something else too: drift doesn’t always look the same. The three cases below are all failures I’ve run into myself. Here’s what happened, why it happened, and how to avoid it. Failure 1: Work Directions Got Mixed Together What Happened I was figuring out the approach for a project. I first discussed Approach A with AI, building a data dashboard. After 4 turns, it didn’t feel deep enough, so I switched to Approach B, automated reports, for another 3 turns. Then I thought maybe I could combine Approach C’s real-time push capability. Three directions kept jumping around in the same conversation for a dozen turns. ...

Today’s Practice Pick a real multi-step task you have on hand, and hold a conversation with AI for at least 15 turns (one question + one answer = one turn). Example tasks: “Help me plan a family trip (destination, itinerary, budget, packing list)” “Help me set up a personal blog from scratch (pick a platform, choose a theme, write the first post)” “Help me analyze a career decision (take stock of where I am, pros and cons, action plan)” Let the conversation unfold naturally without forcing strict structure at first, but do pause around turn 10 and run the progress-summary checkpoint.
