# Fish completion for CCS (Claude Code Switch)
# Compatible with fish 3.0+
#
# Installation:
#   Copy to ~/.config/fish/completions/:
#     mkdir -p ~/.config/fish/completions
#     cp scripts/completion/ccs.fish ~/.config/fish/completions/
#
#   Fish will automatically load completions from this directory.
#   No need to source or reload - completions are loaded on demand.
