concurrent-session-checkout-clobbers-shared-worktree skillA
concurrent-session-checkout-clobbers-shared-worktree is agent-read markdown (skill) from wan-huiyan/agent-traffic-control: A second Claude Code session (or agent/person) sharing the same working directory runs `git checkout`/`git switch`, flipping the branch for the whole working tree underneath your session and clobbering your uncommitted work. Use when: (1) a file you just edited has silently reverted — often with a "file was modified, either by the user or by a linter" system reminder, (2) `git branch --show-current` shows a branch you didn't switch to, (3) `git reflog` shows a `checkout: moving from X to Y` you .
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add wan-huiyan/agent-traffic-control/concurrent-session-checkout-clobbers-shared-worktree@v1.2.0mdr add wan-huiyan/agent-traffic-control/concurrent-session-checkout-clobbers-shared-worktree@sha256:e9138c707caf8605Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
