Post to YouTube from Codex

Short answer: paste npx scorper@latest init into Codex, sign in with the code it emails you, say “connect my youtube”, approve in your browser, then describe the post. Codex reads it back and publishes to YouTube when you say yes. YouTube is one of five platforms on the same connection, with Instagram, LinkedIn, TikTok, X and YouTube all set up the same way.

How to connect YouTube to Codex

  1. 1

    Paste the install line in Codex

    OpenAI's Codex CLI runs in your terminal, so the install is the same one-line command as everywhere else. It adds the Scorper skills to Codex and links this machine to your account with a scoped key. There is nothing to configure in a JSON file and no API key to paste.

    Type into the Codex chat, or into any terminal
    npx scorper@latest init

    Needs Node 18 or newer. scorper doctor confirms the install afterwards.

  2. 2

    Sign in with the code from your email

    Codex asks for your email. A 6-digit code arrives, you type it into the chat. No account yet? One is created on the spot, no password. You pick a plan and its 7-day free trial starts at checkout.

  3. 3

    Say “connect my youtube”

    Codex opens YouTube's approval page in your browser. Log into the right YouTube account first, approve, come back. Codex confirms the connection.

  4. 4

    Tell it what to post

    upload ./exports/episode-12.mp4 to youtube as a short, title and description from notes.md

    Codex uploads the media, proposes a caption, then reads the whole post back. Say yes and it publishes to YouTube. Say “schedule it for 6pm tomorrow” instead and it queues it.

What you can publish to YouTube from Codex

Video uploads, including Shorts, with title and description, to a connected YouTube channel.

YouTube is the platform where the metadata does the work. A good prompt names the file and the source for the title and description: "upload episode-12.mp4 to youtube, title and description from notes.md, three tags". Your AI drafts both within YouTube's limits, reads them back, and uploads. Vertical clips under three minutes are treated as Shorts. Local files up to 300 MB (MP4 or MOV) upload through the connection.

YouTube's own rules, which your AI works within

RuleYouTube
TitleUp to 100 characters.
DescriptionUp to 5,000 characters.
ShortsVertical video up to 3 minutes is shown as a Short.
VisibilityPublic, unlisted or private is set at upload time.
TitleThrough Scorper, the first line of your caption becomes the video title, so write that line as a title.
File sizeUp to 256 GB or 12 hours, whichever is first.

Prompts that work in Codex

connect my youtube
upload ./exports/episode-12.mp4 to youtube as a short, title and description from notes.md
schedule this video for 4pm thursday on youtube, unlisted

Scheduling: “schedule this for 9am monday on youtube”. The calendar: “what's going out this week?”. Moving things: “move friday's post to saturday”. Everything you schedule from Codex also shows in the dashboard calendar.

Something only Codex users should know

Codex and Claude Code share one Scorper account on the same machine: the install links the machine, not the agent. If you already set up Claude Code, run the same command from Codex to add the Codex-side skills; the existing account link is reused.

What happens before anything posts

The read-back, every time
⏺ Posting to YouTube your channel
   Caption: "Three things I wish someone told me at 21…"

Your machine holds a scoped key. YouTube's own credentials stay on Scorper's side, and Codex never sees a platform token.

Honest limits

  • YouTube publishing goes through the official YouTube API, so YouTube's rules above apply. Scorper does not work around them.
  • The AI-agent connection is on every plan. Pro posts to Instagram only. Max ($25 a month), Studio and Agency post to every social.
  • The install needs Node 18 or newer on the machine.
  • Some things are easier in the dashboard than in chat: bulk-editing a month of scheduled posts, for example. Both views share one calendar.

Frequently asked questions

Can Codex post to YouTube on its own?
Not without a connection. Codex can write a caption but has no permission to publish. Scorper is that permission: one command installs the posting skills and links your machine to your account, then Codex can publish and schedule to YouTube through the official API.
Can it upload YouTube Shorts?
Yes. A vertical video under three minutes is treated as a Short by YouTube. Ask for it explicitly ("as a short") so the title and description are written for the format.
Can I upload as unlisted or private first?
Yes. Say "unlisted" or "private" in the prompt. You can change visibility later on YouTube.
I already set Scorper up in Claude Code. Do I need to do it again for Codex?
Run npx scorper@latest init once more from Codex to install the Codex-side skills. The account link belongs to the machine, so both agents post through the same connected accounts.
Will it post without asking me?
No. Codex reads the exact post back (platform, media, caption) and publishes only after you confirm. Scheduled posts are shown before they are queued.
What does posting to YouTube from Codex cost?
The AI-agent connection is included in Scorper Max ($25 a month, one brand, all five platforms) and Studio ($55 a month, three brands). Every plan starts with a 7-day free trial, card needed to start.
