The composer routed everything through tmux paste-buffer -p (bracketed
paste), and Claude's TUI deliberately doesn't parse a leading slash on
pasted input — so /command and /skill arrived as literal text instead of
running. Now a recognised command (single-line, leading slash, token in
ClaudeConfig's slash list) is delivered via send-keys -l (typed) so the
TUI fires it; everything else keeps the bracketed-paste path, which also
leaves a stray leading slash (e.g. a /tmp path) as literal text rather
than mis-parsing it. The slash list is warmed lazily when a Claude pane
opens so custom commands are recognised.
