Video Codex Claude Code Registration Guide is an English video tutorial note from Hooosberg. It keeps the Bilibili lesson link, cleaned-up course structure, prompts, and workflow notes together.

The original Chinese note is tagged with video tutorial, Claude Code, Claude Pro, AI coding, build note, build note, build note. The goal is not a transcript, but a clearer companion note for people who want slides, prompts, and repeatable steps.

Future course updates can add the episode URL at the top, then summarize the goal, materials, prompts, checks, and reusable workflow.

Lesson approach

This companion note follows the same order as the video: understand the work problem first, prepare the files and rules, run the prompts in sequence, then verify the output before treating it as usable.

The Chinese source lesson covers 一、背景痛点：为什么大家纷纷转向 Claude Code？, 二、前期准备条件, 三、购买美区礼品卡与充值（解决支付问题）, 四、下载 Claude App 并开通 Pro 会员, 五、电脑端登录与 Claude Code 终端命令行环境配置, 六、实战选型心得：Claude 模型梯队与性价比深度剖析, 七、长期稳定使用防封规范（避坑指南）, 八、延伸探索：全球大模型竞技场实时排行榜. It is designed as a practical workflow note, not a detached summary: the reader should be able to pause the video, complete one step, and return to the next step with evidence of what changed.

How to study with the video

On the first pass, watch for the inputs, constraints, and expected outputs. On the second pass, reproduce the workflow in a separate test folder. Keep source files unchanged and save generated reports, cleaned data, drafts, or exports in the designated output location.

Do not treat an AI response as a final decision. Check whether the task was fully specified, whether uncertain values were labelled, whether the result can be traced back to source material, and whether a human approval is needed before any submission, purchase, application, or external action.

Copy-ready source prompts

The original prompts are kept below in Chinese so that the operational meaning used in the video is not weakened by translation. Replace every sample file name, person, company, amount, rule, and destination with verified information from your own task.

# 1. 全局安装 Claude Code CLI
npm install -g @anthropic-ai/claude-code

# 2. 进入你的项目文件夹并启动
cd /path/to/your/project
claude

Knowledge points and checks

The transferable skill is not a single prompt. It is the ability to turn scattered materials into a repeatable system: inputs have fixed locations, rules are written down, intermediate work is separated from final deliverables, and exceptions are visible instead of silently invented.

Before closing the task, verify four things: the input set is complete; unknown information is marked rather than guessed; the output is saved where the workflow expects it; and a small sample can be checked against the original files. High-impact decisions always remain subject to human review.

Wrap-up

Reuse the structure rather than copying the example blindly: define the objective and boundary, organize files and rules, run the steps in order, verify the result, and keep the workflow for the next similar task.

That is the central lesson behind this WorkBuddy series: AI becomes more reliable when work is expressed as a clear, inspectable process instead of a vague request for a finished answer.
