# Bash Script Installer for Zsh
The "Bash Script Installer" simplifies the setup of Zsh.

## Zsh
### Ubuntu
```zsh
bash -c "$(curl -fsSL https://tinyurl.com/y6fhb594)"
```
### WSL
```zsh
bash -c "$(curl -fsSL https://tinyurl.com/ycyct6wp)"
```
### MacOS
```zsh
bash -c "$(curl -fsSL https://tinyurl.com/yptybtpa)"
```

### Configuration
```zsh
bash -c "$(curl -fsSL https://tinyurl.com/y8vf753j)"
```

### Shell framework and prompt
The installers use Oh My Zsh for framework features and plugins, with the OMZ theme disabled:

```zsh
ZSH_THEME=""
source "$ZSH/oh-my-zsh.sh"
eval "$(starship init zsh)"
```

Starship owns the prompt and loads after Oh My Zsh. The managed Starship config is installed at `~/.config/starship.toml`. A Nerd Font is required for the Powerline symbols.

## Plan-build workflow

The local `plan_build` function is a thin cached launcher for the canonical public [plan-build gist](https://opengist.resetrix.work/weehong/plan-build). When curl is available, each invocation stages `plan_build.zsh`, `SKILL.md`, and `ARCHITECT.md`, requires all three to be non-empty, and syntax-checks the executable. It then moves the complete bundle into a unique immutable release directory and atomically switches one `current` symlink. Refresh activation is serialized with a kernel-backed Zsh file lock so concurrent callers cannot mix releases and crashes cannot leave a stale lock. If refresh fails, the launcher preserves and uses the last complete, validated release and repairs its skill links. Zsh is always required; curl is required only when no valid cached release exists.

```zsh
plan_build
plan_build --prompt
plan_build --writing-plan
plan_build --prompt --brainstorm
plan_build --yolo --writing-plan
plan_build --architect
plan_build --architect --new
plan_build --architect --yolo
```

The canonical executable defines the current command behavior and options. Each invocation binds the executable and both skills to its selected immutable release. The launcher also points the installed Claude Code skill paths through the active `current` release:

- `SKILL.md` → `~/.claude/skills/plan-build/SKILL.md`
- `ARCHITECT.md` → `~/.claude/skills/plan-build-architect/SKILL.md`

The launcher defaults to `https://opengist.resetrix.work/weehong/plan-build/raw/HEAD` and `${XDG_CACHE_HOME:-$HOME/.cache}/plan-build`. Override these with `PLAN_BUILD_BASE_URL` and `PLAN_BUILD_CACHE_DIR`. Installed skill paths remain fixed at `~/.claude/skills`; cached invocations receive immutable release paths through environment variables. The downloaded script is remote executable code: syntax validation catches malformed Zsh but is not a security sandbox, so only point `PLAN_BUILD_BASE_URL` at a source you trust. Remote code is executed in a child Zsh process and is never sourced into the caller shell.

Invoking `plan_build` once installs or repairs both skill links. To install standalone files without the cached launcher, follow the installation instructions in the canonical gist instead.
