I saw some other cool projects (lavra and linear-beads, credieted in my repo readme) which added an accumulating knowledge base and linear to the beads concept, so I just stole both ideas and put them into a plugin for myself. I have been dogfooding it for a couple of days.
It works pretty well but I'm the only user and it's opinionated around how I like to do things. It also uses the linear MCP which is way slower and less token-efficient than the linear CLI on homebrew. I might update it in the future.
If this appeals to you, check it out.
