install.sh

#!/bin/bash
# install.sh - put housebroken where the current user's agent can reach it.
#
# Two destinations and nothing else: the gate scripts, the `housebroken`
# dispatcher and a VERSION file go into $HOUSEBROKEN_HOME/bin, and the skill
# directory goes into $HOME/.claude/skills/housebroken, which is where Claude
# Code looks for a user skill. No profile is edited, no PATH is changed, no
# state is written anywhere else; when the bin directory is not on PATH the
# one line to add is printed for the operator to add by hand.
#
# Other agent hosts (Codex, Cursor, Copilot) are not wired up yet.
# skills/housebroken/SKILL.md is the source of truth for every future adapter:
# an adapter converts that file, it does not restate its rules.
#
# Usage:
#   bash install.sh              # install
#   bash install.sh --dry-run    # print what it would do, change nothing
#   bash install.sh --uninstall  # remove exactly what install put there
#   bash install.sh --help
#
# Environment:
#   HOUSEBROKEN_HOME  install root, default $HOME/.housebroken. The scripts and
#                     the dispatcher go in its bin/ subdirectory.
#   HOME              the user home; $HOME/.claude/skills is the skill root.
#
# Assumes bash and a writable HOME. Works from any working directory: the repo
# root is resolved from this file's own location.
