# CoderLap Docs Toolkit — one-line installer
# Usage:  curl -fsSL https://coderv.dev/install.sh | bash
#
# Default: clones the toolkit and runs its installer, which copies the 5
# slash-command skills into ~/.claude/skills/ and wires the coderv-router
# UserPromptSubmit hook into ~/.claude/settings.json (Claude Code only).
#
# Flags pass through to the toolkit installer:
#   --codex / --gemini / --all   install for those CLIs (skills only — no hook)
#   --force                       overwrite existing files
#   --uninstall                   remove the toolkit
#
# --project is handled by THIS script (drops skills into ./.claude/skills/
# of the current directory, no hook).

Hosts (default is Claude Code):
  --codex       Install to ~/.codex/skills/   (skills only — no hook)
  --gemini      Install to ~/.gemini/skills/  (skills only — no hook)
  --all         Install to Claude + Codex + Gemini

Other options:
  --project     Install into ./.claude/skills/ of current dir instead of ~
  --force       Overwrite existing skills without asking
  --uninstall   Remove toolkit skills (and the router hook on Claude Code)
  --help        Show this message

Installs the 5 CoderLap slash commands:
  /docify, /before, /decision, /ship, /session

On Claude Code, also installs the coderv-router hook so the right command
is suggested automatically when your phrasing matches.
