dag-library

dag-library is an open-source workflow skill for Claude Code and compatible agents, published by code-yeongyu. Its author describes it as: “Store a dag definition once and re-run it in one or two lines, instead of pasting the full definition JSON into every eval cell. MUST USE whenever the user wants to save a DAG for reuse, run a previously saved/named D…”. The project has 68k stars on GitHub and ships custom license terms, so review them before reuse. Add it to your setup with `git clone https://github.com/code-yeongyu/oh-my-openagent ~/.claude/skills/dag-library`.

What dag-library does
