public.skill_version

Columns

Name	Type	Default	Nullable	Children	Parents	Comment
contentHash	varchar(64)		false			sha256 of name, description, instructions, frontmatter and files. Save creates no version when the content matches the latest one
createdAt	timestamp(3) with time zone	CURRENT_TIMESTAMP(3)	false
createdById	uuid		true		public.user	Author. NULL after the author is deleted
description	varchar(1024)		false
frontmatter	json		true			SKILL.md frontmatter fields other than name and description, e.g. allowed-tools
id	uuid		false	public.agent_skill_dependency public.agent_version_skill_dependency public.skill_file
instructions	text		false
name	varchar(128)		false			Free-text skill name, as it was when this version was saved
skillId	varchar(36)		false		public.skill
updatedAt	timestamp(3) with time zone	CURRENT_TIMESTAMP(3)	false
version	integer		false			1..n per skill. A Save that changes the content adds one; none ever changes
