Install
Skills CLI
npx skills add kajitiluna/erd-designer
Asks which skills and agents to install. Just one: npx skills add kajitiluna/erd-designer --skill update-changelog — add -g for every project.
Claude Code
git clone https://github.com/kajitiluna/erd-designercp -r "erd-designer/.claude/skills/update-changelog" ~/.claude/skills/
Copies the update-changelog skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add kajitiluna/erd-designer
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md.
-
update-changelog
Generate and insert a new CHANGELOG.md version entry from git changes between main and the current branch. Use this skill whenever the user wants to update CHANGELOG.md, write release notes, document what changed since branching from main, or add a new version entry. Trigger on phrases like "update changelog", "add changelog entry", "document changes".
.claude/skills/ on GitHub (opens in a new tab)update-changelog/ SKILL.md -
erd-designer
Create and edit ERD Designer .erd files (database entity-relationship diagrams). Use when the user asks to design database tables, add or modify tables, columns, relations, indexes or memos in a .erd file, to export DDL from a .erd file, or to check whether a .erd design matches another revision or a live database.
agent-plugin/skills/ on GitHub (opens in a new tab)erd-designer/ SKILL.md

Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
