This repository is a curated collection of Codex skills referenced in the AI tools for developers training talks. It keeps the skills in one ordinary git repository so they can be reviewed, installed, edited, and used as examples of how skills package reusable agent workflows.

Installation

Run the setup script to symlink each skill directory into your Codex skills folder:

./setup-skills.sh

By default, skills are linked into $HOME/.codex/skills. To install somewhere else:

CODEX_SKILLS_DIR=/path/to/skills ./setup-skills.sh

To preview what would be linked:

./setup-skills.sh --dry-run

The installer discovers every top-level directory that contains a SKILL.md file.

Included Skills

Local / Custom Skills

gitea-issues - work with self-hosted Gitea repositories, issues, pull requests, and issue dependency workflows.

Scope

This repo intentionally includes only the skills referenced in the training talks. Other personal skills may exist elsewhere, but they are left out here so the examples match the material from the presentations.
