# Project Session Manager (PSM) Skill

Every issue, PR and feature in its own clean workspace

## What this does

Working on two things at once in one checkout means stashing, switching and losing your place. This gives each issue, PR or feature its own worktree, and can put a tmux session around it if you like working that way. Reach for it when you juggle more than one piece of work at a time.

### Top 3 things it does for you

- Spin up a workspace for this issue
- Work on a PR without disturbing my main checkout
- Start a feature in its own tree, with tmux if I want it

## About Project Session Manager (PSM) Skill

This manages dev environments with worktrees first: an issue, a PR or a feature each gets its own, so what you are doing in one does not disturb another.

If you like a terminal session wrapped around each workspace, tmux sessions are there as an option. If you do not, the worktrees work on their own.
