Skills for Codex.

Save to a project

Save complete folders into .agents/skills/<skill>/. The personal scope for all projects is ~/.agents/skills/<skill>/. Download and read the packages first:

context4_skill_tmp="$(mktemp -d)"
for skill in context4 context4-setup; do
  curl --fail --location "https://ctx4.me/skills/$skill/archive.zip" --output "$context4_skill_tmp/$skill.zip"
  unzip -l "$context4_skill_tmp/$skill.zip"
done
# Read SKILL.md and references before installing.
mkdir -p .agents/skills
for skill in context4 context4-setup; do
  unzip -n "$context4_skill_tmp/$skill.zip" -d .agents/skills
done

unzip -n does not overwrite files. If a folder already exists, compare versions: skipping it does not mean an update succeeded. In a new conversation, check that context4 and context4-setup appear. Add context4-workflows in the same way for tasks across systems.

Configure MCP separately. All files. If the agent cannot access files, save them manually or use the instructions in the current chat without claiming persistent installation.

Official specification.
