# radin: Update `install.sh` covers fresh interactive install only. Skill re-applies against already-installed radin so `~/.claude/agents/` and `~/.claude/skills/` overwrite with the latest changes. Companion-tool installers in `install.sh` already skip-if-installed, so re-run safe. `install.sh`'s source resolution has two modes — check which one applies before doing anything else: - **Downloaded tarball** (the normal `curl | bash` path): source lives at `~/.claude/radin` (or `RADIN_ROOT_OVERRIDE`), marked by a `.radin-version` file, no `.git` dir. Nothing to pull — just re-run `install.sh`, which re-downloads the latest release (or `main`) itself. - **Manual dev clone** (someone hacking on radin itself, ran `git clone` + `./install.sh`): source has a `.git` dir. Needs an explicit `git pull` before re-running `install.sh`. ## Step 1: Locate source Read `~/.claude/.radin/install_root` — `install.sh` writes the resolved source path there each run. File missing (install predates this skill): ask user for the path instead of guessing. ## Step 2: Branch on source mode ```bash SRC="$(cat "$HOME/.claude/.radin/install_root")" if [ -d "$SRC/.git" ]; then MODE=git-clone elif [ -f "$SRC/.radin-version" ]; then MODE=tarball else echo "unrecognized source at $SRC, stop"; exit 1 fi ``` ### git-clone mode Confirm clean working tree before touching anything: ```bash cd "$SRC" git status --porcelain ``` Anything printed: stop, report — don't pull over uncommitted l
