update-skills

Portable Codex skill registry and updater.

This repository publishes the update-skills Codex skill at skills/update-skills. It can:

• register trusted GitHub skill sources
• check installed skills for remote changes
• apply approved updates with local backups
• export a portable source list
• import a source list and install missing skills on another computer

Install

From Codex, install this skill from:

https://github.com/sybxxx/skills-updater/tree/main/skills/update-skills

Or run the bootstrap script from PowerShell:

iwr https://raw.githubusercontent.com/sybxxx/skills-updater/main/install.ps1 | iex

The bootstrap script installs update-skills, then automatically installs any missing skills from the bundled sources.json. Restart Codex after installation.

Sync Skills On Another Computer

Export the registry on the first computer:

python "$env:USERPROFILE\.codex\skills\update-skills\scripts\skill_updater.py" export --output codex-skills-export.json

Move codex-skills-export.json to the second computer, install this skill there, then run this only if you want to sync from that exported list instead of the bundled list:

python "$env:USERPROFILE\.codex\skills\update-skills\scripts\skill_updater.py" install-missing --input .\codex-skills-export.json --yes

Safety

The updater installs and updates only skills listed in sources.json or in an imported export file. It does not update .system skills, and update operations create backups under $CODEX_HOME/skill-backups.
