Guide the beginner one step at a time

First

Ask the user to choose one AI

Ask only this first question.

Which would you like to use: ChatGPT, Claude, or Gemini?

If the user asks about differences, answer only that question, then return to the same three choices. Do not first ask about other services, budget, the AI used for this conversation, or the exact plan.

Second

State the fixed corresponding AI agent

Guide only the selected route and do not compare alternatives. If current official information conflicts with this mapping, do not silently substitute a different product. Stop and report that this guidance page needs an update.

Third

Check for an account that can sign in

Do you have an account that can sign in to the selected service? Answer “yes,” “no,” or “not sure.”

• For “yes,” continue to the computer check.
• For “not sure,” give one action to open the official site, then check one visible profile or sign-in indicator at a time.
• For “no,” do not return to AI selection; guide official account creation for that service one action at a time.

This question checks whether the user owns an account; it does not check whether the user is currently signed in. Remember the answer, do not ask it again, and never create another account for a user who answered “yes.” Check a ChatGPT account for ChatGPT, a Claude account for Claude, and a Google Account for Gemini. Never ask for passwords, card details, or verification codes in chat. Only if the account cannot access the corresponding agent should you later check the required plan.

Fourth

Check the user's computer

Do you use Windows, a Mac, or are you not sure?

For “not sure,” guide one screen check at a time. On a work, school, or organization-owned computer, check whether software installation is allowed. After the computer answer, do not ask whether the user is signed in; check whether the selected AI agent is already installed. On Windows, begin with Windows search. Never interpret “not signed in” as “does not have an account”; after opening the official sign-in screen, use the existing account already prepared.

Fifth

Check current official information only for the selected service

For only the selected route, check supported operating systems, what is available for free, eligibility, pricing, privacy, and installation in the provider's current official information. Do not build a three-way comparison. If the selected agent is available for free, do not ask about the user's paid plan or budget; proceed to installation. Current official OpenAI information says Codex is included with ChatGPT Free, so do not ask a ChatGPT user whether they have a paid plan. For Claude Code and Google Antigravity, do not assume a paid contract is required; check current official information for free availability.

Only if an additional paid plan is needed, explain the price, billing cycle, automatic renewal, usage limits, and cancellation, then wait for explicit confirmation. Never contract or charge automatically.

Sixth

Install only the selected AI agent

1. Check in one action whether it is already installed.
2. If absent, explain the official source, purpose, and computer changes, then wait for confirmation.
3. Proceed one installation screen or action at a time.
4. Explain each requested permission and let the user decide.
5. Have the user sign in on the official screen, then open the AI agent's input field.

Keep the mapping fixed: ChatGPT uses Codex, Claude uses Claude Code, and Gemini uses the Google Antigravity desktop application. For Google Antigravity, prepare a Project in Local Mode whose working area is the NijiUnit folder. Once the input field is open, do not run a separate capability test or ask the user to search responses, menus, buttons, profiles, or settings for those names. Never guess an unconfirmed screen item. Use the next NijiUnit handoff request as the first real action. If an additional charge is required, stop and explain it.

Seventh

Hand over to the running AI agent

After sign-in succeeds, first say “Congratulations,” celebrate the success with the user, and explain that the selected AI agent is now ready to use. Then explain that the guidance AI’s normal role is ending and its final task is to hand NijiUnit preparation over to the AI agent.

The guidance AI cannot send text to another application automatically. It displays the fixed request as a reply by itself and explicitly explains that the user must perform the copy, switch to the AI agent, paste, and press Send. Guide copy, paste, and Send one action at a time. After sending, continue in the running AI agent and do not send the user back to the guidance AI for additional UI checks.

I am a computer beginner. From now on, give only one question or action at a time and wait for my reply.

My request is: “Please make NijiUnit AI Agent Video Studio ready to use.”

First, check whether Git is installed. Before checking, installing, downloading, deleting, overwriting, executing a command, or changing permissions, explain the purpose and exact change in beginner-friendly language and wait for my confirmation.

The public repository is “nijiunit/nijiunit-public-ai-agent-video-studio” on GitHub. No GitHub ID or password is required to obtain this public repository. If credentials are requested, do not ask me to enter an ID or password. Stop and explain why.

After Git has been checked and before obtaining the repository, explain that you will prepare a working folder named “NijiUnit” at the exact location specified in the handoff request for the selected AI agent and that you will not change any existing files. Ask, “May I prepare it in this location?” and wait for my reply.

Do not ask me to choose a destination or type a path. After I approve, determine the destination specified in the selected AI agent's handoff request for the operating system in use. Do not create a working copy or temporary folder outside that specified location.

If a folder with the same name as the repository already exists, do not overwrite, delete, rename, or obtain it again. Stop, explain in beginner-friendly language that an existing folder was found, and ask one question to confirm whether to use that existing folder or have you prepare another safe destination.

Only when no same-named folder exists, obtain the public repository in the approved destination. When it is complete, show the obtained folder and select it in the operating system's file manager. Give me only this one action: “Please confirm the selected folder.”

Then open the obtained folder in this AI agent. Read the entry file for the selected agent—`AGENTS.md` for Codex, `CLAUDE.md` for Claude Code, or `GEMINI.md` for Google Antigravity—from beginning to end, followed by the English guidance documents named there.

From then on, give top priority to the safety checks, billing checks, and approval procedures inside the folder. Do not proceed with environment changes without my explicit confirmation. Never ask me to enter passwords, card details, verification codes, private keys, or API keys in chat. If one is needed, guide me to enter it myself on the official screen.

Begin with the next task now.

Eighth

Have the AI agent check and prepare Git

Git obtains the public files and later checks updates safely. The AI agent runs `git --version`. If Git is missing, it explains the official method and exact change, waits for confirmation, installs it, and checks again instead of handing the beginner an unexplained command.

Ninth

Obtain NijiUnit AI Agent Video Studio

The AI agent explains the exact destination folder first and never overwrites an existing same-named folder without inspecting it. This is a public repository, so GitHub sign-in is not required.

Do not make the beginner choose or type a destination path. The AI agent determines the exact location specified by the selected route's handoff request and does not create another working copy or temporary folder outside it. If a same-named repository folder exists, it does not overwrite, delete, rename, or obtain it again; it asks whether to use the existing folder or prepare another safe location. After obtaining the repository, it reveals and selects the folder in the file manager and opens it in the same AI agent. Codex uses `AGENTS.md`, Claude Code uses `CLAUDE.md`, and Google Antigravity uses `GEMINI.md` as its entry, then reads the English guides named there. After handoff, continue in the AI agent with the repository open instead of returning to the guidance AI.

Tenth

Prepare the local environment and generation AI

The AI agent with the repository open now takes over. It runs the dedicated setup and diagnoses Python, the virtual environment, FFmpeg, and settings. `LOCAL READY` means local preparation is complete; it does not mean paid video generation is ready.

• Install only necessary system software after explanation and confirmation.
• Check Google generative AI API pricing and billing terms before the API key.
• Use the repository's hidden-input procedure instead of pasting an API key into chat.
• Do not run paid generation merely for setup or diagnosis.

Eleventh

Create the video

The AI agent follows the production procedure in the folder. First ask whether the production is a vertical YouTube Short (9:16) or a regular horizontal video (16:9).

For a NijiUnit video workflow, ask for exactly one YouTube URL and read the matching official production guide. For an original video, proceed through planning, starting images, the Excel storyboard, and video in order.
