# Fish completion for CCS (Claude Code Switch)
# Compatible with fish 3.0+
#
# Features:
#   - Categorized completions with [cmd], [model], and [account] prefixes
#   - Dynamic profile loading from config.json and profiles.json
#   - Context-aware subcommand completion
#
# 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.
