Uninstall

Turn the SSH agent off first, if you had it on, and press Remove Plugin Data on the settings screen. Between them those clear everything this plugin put outside its own folder: the helper stops cleanly and takes its socket, FIFO and routing file with it, and the button clears the keyring entries, the learned suggestions, the exported public keys and the sign-ins of any accounts added beside the first. Both have to happen before the next step, because omarchy plugin remove has no uninstall hook -- once the folder is gone there is no code left to run.

omarchy plugin remove io.github.elevate08.qs-bitwarden-cli

That removes the plugin folder and its bar entry. If you skipped the two steps above, or you are cleaning up after a plugin that is already gone, this is the same work by hand:

# Session key, and the encrypted master password quick unlock uses (plus any
# per-method entries left by 1.10.0 or earlier)
secret-tool clear service qs-bitwarden-cli

# Learned window-title -> vault item suggestions
rm -rf "${XDG_STATE_HOME:-$HOME/.local/state}/qs-bitwarden-cli"

# Settings block: already gone. `omarchy plugin remove` takes the bar entry
# and its settings with it. If a stale one is left -- from a plugin removed
# some other way -- clear it through the shell, never by editing the file:
#   omarchy plugin disable io.github.elevate08.qs-bitwarden-cli

# Accounts added beside the first: their own bw data directories and the list
rm -rf "${XDG_DATA_HOME:-$HOME/.local/share}/qs-bitwarden-cli/accounts"

# SSH agent, if you used it: the exported public keys and the routing file
rm -rf "${XDG_DATA_HOME:-$HOME/.local/share}/qs-bitwarden-cli/ssh"
rm -f ~/.config/uwsm/env.d/50-qs-bitwarden-ssh-agent

Do not hand-edit ~/.config/omarchy/shell.json. On many setups it is not a regular file: Omarchy configs are commonly managed with stow or another dotfile manager, which puts a symlink there pointing into a repository. Deleting "the file" then deletes the link, the shell falls back to its built-in defaults, and every plugin you had configured disappears at once -- not just this one. The config itself is unharmed, sitting in the repository the link pointed at, but working that out from an empty bar is not a pleasant few minutes. Every command above goes through the shell or touches only this plugin's own paths.

The agent's socket, FIFO and lock under $XDG_RUNTIME_DIR are removed when the helper shuts down, which is what turning the agent off does. If the plugin is removed with the agent still running, the helper is killed instead, and the panel removes those three files from a detached script once the helper's lock is released. Deleting the directory by hand is also safe once no helper is running.

Two more paths are written but need no cleaning up, because neither outlives the moment it is used: the session handoff file under $XDG_RUNTIME_DIR, which is read once and deleted and is on a tmpfs that goes with the login session, and a .qsbw- staging directory inside your download folder, which exists only for the length of an attachment download and is removed however that download ends. Saved attachments themselves stay where you saved them, mode 600.

Beyond those, the plugin writes nothing outside the paths above and your shell.json entry, and it never modifies your Bitwarden vault on removal. Your vault is untouched -- log out of the bw CLI separately with bw logout if you also want that cleared.
