3. If only some artifacts exist, report partial state and resume verification before retrying any publish action. Never republish a version already on npm. Missing binaries never need an npm action: re-run `binaries.yml` with `workflow_dispatch` and the release tag to attach them.
4. Once all artifacts exist, read [references/release-notes.md](references/release-notes.md), polish the GitHub Release, and verify the saved title/body.

Deploy the /cli/install.ps1 route before merging the Windows command.

The README now points Windows users to https://openspec.dev/cli/install.ps1. That URL returned HTTP 404 when checked. The PR description names only the openspec.dev/cli/install.sh redirect as a prerequisite, so nothing in the PR establishes that the PowerShell route will exist at merge. If it stays absent, the Windows Quick Start command in README.md fails. Confirm that /cli/install.ps1 serves the intended script before this change merges. Keep the GitHub-hosted PowerShell command until the route is live.

## Install

OpenSpec installs as a single `openspec` file. It needs no Node.js.

On macOS or Linux, in your terminal:

```bash
curl -fsSL https://raw.githubusercontent.com/Fission-AI/OpenSpec/main/scripts/binary/install.sh | sh
curl -fsSL https://openspec.dev/cli/install.sh | sh
```

On Windows, in PowerShell:

```powershell
irm https://raw.githubusercontent.com/Fission-AI/OpenSpec/main/scripts/binary/install.ps1 | iex
```

- **Where it goes**: `~/.local/bin`; on Windows, `%LOCALAPPDATA%\Programs\openspec`, which it adds to your user PATH.
- **What it checks**: it picks the file for your machine and verifies it against the release's `SHA256SUMS` before installing.
- **Which release**: the newest one whose files are all attached. For the few minutes after a release is published while its files upload, it installs the previous one and says so.
- **Alpine Linux**: run `apk add libstdc++ libgcc` first.
- **Options**: set `OPENSPEC_INSTALL_DIR` to install elsewhere, or `OPENSPEC_VERSION=v1.15.0` to pin a release.

If the installer says the folder isn't on your PATH, add it as it shows. Then [check it worked](#check-it-worked).

The workflow itself runs inside an AI coding tool: Claude Code, Cursor, or any other tool on the [supported list](../reference/supported-tools.md).

### Download it yourself

Each [release](https://github.com/Fission-AI/OpenSpec/releases/latest) has one file per platform:

| Platform | File |
|---|---|
| macOS 13+ (Apple silicon / Intel) | `openspec-darwin-arm64` / `openspec-darwin-x64` |
| Linux, glibc 2.17+ (arm64 / x64) | `openspec-linux-arm64` / `openspec-linux-x64` |
| Alpine 3.17+ (arm64 / x64) | `openspec-linux-arm64-musl` / `openspec-linux-x64-musl` |
| Windows 10+ (arm64 / x64) | `openspec-windows-arm64.exe` / `openspec-windows-x64.exe` |

Rename it to `openspec` (`openspec.exe` on Windows), run `chmod +x openspec` on macOS or Linux, and put it in a folder on your PATH.

> [!NOTE]
> macOS blocks a file downloaded in a browser until you run `xattr -d com.apple.quarantine openspec`. The install command above doesn't need this.

### Verify a download

Each release binary comes with a signed record of the workflow run that built it. With the [GitHub CLI](https://cli.github.com), in your terminal:

```bash
gh attestation verify openspec-darwin-arm64 --repo Fission-AI/OpenSpec
irm https://openspec.dev/cli/install.ps1 | iex
```

It confirms the file is the one that release's workflow built, or fails. This is optional; the installer already checks every download against `SHA256SUMS`.
If the installer prints an `export PATH=...` line, run it. Then [check it worked](#check-it-worked).

Next, [set up your project](setup.md). If your assistant already ran init, that page shows what it wrote and how to adjust it.

## Install options

To pick a version or a folder, set a variable before `sh`:

```bash
curl -fsSL https://openspec.dev/cli/install.sh | OPENSPEC_VERSION=v1.15.0 sh
```

- **`OPENSPEC_VERSION`**: the release to install, such as `v1.15.0`. The default is the newest release.
- **`OPENSPEC_INSTALL_DIR`**: the folder to install to. The default is `~/.local/bin` (Windows: `%LOCALAPPDATA%\Programs\openspec`).

On Windows, set the variable first:

```powershell
$env:OPENSPEC_VERSION = 'v1.15.0'
irm https://openspec.dev/cli/install.ps1 | iex
```

On Alpine Linux, run `apk add libstdc++ libgcc` before installing.

### Download by hand

Each release has one file per computer:

| Computer | File |
|---|---|
| Mac, Apple silicon | `openspec-darwin-arm64.tar.gz` |
| Mac, Intel | `openspec-darwin-x64.tar.gz` |
| Linux, arm64 | `openspec-linux-arm64.tar.gz` |

| Windows, arm64 | `openspec-windows-arm64.zip` |
| Windows, x64 | `openspec-windows-x64.zip` |

1. **Download** your file from the [latest release](https://github.com/Fission-AI/OpenSpec/releases/latest). Files are attached a few minutes after a release is published. If yours isn't listed yet, wait and reload, or take it from the previous release.
2. **Unpack** it. In your terminal: `tar -xzf openspec-darwin-arm64.tar.gz`. On Windows, right-click the `.zip` and choose Extract All.

```bash
gh attestation verify openspec-darwin-arm64.tar.gz --repo Fission-AI/OpenSpec
```

It fails if the workflow didn't build the file. The install command already checks each download against the release's `SHA256SUMS`, so this step is optional.
