XPost is a reusable Codex skill for researching, writing, and auditing posts for X. It supports short posts, X Premium long-form posts, threads, breaking news, frameworks, replies, and other common formats. Drafting follows general, algorithm-aware guidance (reply-weighting, hook timing, link placement) rather than chasing a specific platform update.
XPost also has an optional KOL discovery workflow: point it at a topic and it finds relevant, high-engagement recent posts, then drafts a reviewable reply card for each one. It never auto-posts, auto-likes, or auto-follows, and it never requires or stores credentials, API keys, or a watchlist of accounts — send only what you choose to send.
The skill separates workflow from identity. It ships with a blank voice template and a generic anti-slop check, so the repository contains no personal profile, account history, contact information, private paths, or user-specific persona.
Copy the xpost folder into your Codex skills directory:
~/.codex/skills/xpost
Restart or reload Codex after installation if the skill does not appear immediately.
For better results, create a Voice.md file in the project where you use the skill. Start with xpost/references/voice-template.md.
You can also add an anti-slop.md file with your own banned phrases and style rules. When those files exist, XPost reads them before drafting. Private context stays local and should not be committed to this public repository.
Suggested project layout:
your-project/
|-- Voice.md
|-- anti-slop.md
`-- notes.md
Invoke the skill directly:
Use $xpost to write a contrarian X post about why small AI models will win more production workloads. Audience: technical founders. Use my Voice.md.
Or ask naturally:
Draft a publish-ready X thread from these research notes and run the anti-slop check.
To use KOL discovery:
Use $xpost to find 5 recent posts about on-device AI worth replying to, and draft a suggested reply for each.
XPost does not auto-publish. It produces copy-ready content, sources, and a brief quality report.
Keep identity files, post logs, private analytics, credentials, and contact details outside this repository. Review staged files before pushing changes to any public fork.
