This page is the PowerShell-first path for installing, verifying, and safely switching providers on Windows. It is intentionally copyable without embedding live secrets.
## Choose an install path
### Option A: build from source in PowerShell
Use this when you are developing Claw Code or testing a local checkout.
Use this when a GitHub release publishes a Windows artifact. The release workflow publishes `claw-windows-x64.exe` plus `claw-windows-x64.exe.sha256`; if a future release wraps the binary in a ZIP, prefer the `windows-x86_64` / `pc-windows-msvc` asset and its matching checksum file.
`doctor`, `status`, `config`, and `version` support `--output-format json`; do not use a separate `--json` suffix.
## Safe credential setup
Set keys only in your local environment or a private `.env` file. Do not paste real keys into shell history shared with others, issue trackers, or documentation.
Current PowerShell session only:
```powershell
$env:ANTHROPIC_API_KEY = "sk-ant-REPLACE_ME"
```
Persist for future PowerShell windows:
```powershell
setx ANTHROPIC_API_KEY "sk-ant-REPLACE_ME"
```
Open a new terminal after `setx`. To remove a session-local key while testing provider switching:
.\target\debug\claw.exe --model "openai/gpt-4.1-mini" prompt "reply with ready"
```
For the default OpenAI-compatible API, omit `OPENAI_BASE_URL` or set it to `https://api.openai.com/v1`, and keep the `openai/` or `gpt-` model prefix explicit.
### Local OpenAI-compatible server
Use a loopback URL and a placeholder token unless your local server requires a real one:
.\target\debug\claw.exe --model "qwen-plus" prompt "reply with ready"
```
## Windows and WSL notifications
Notification support is exposed through the `notifications` slash command in the interactive REPL. Use JSON/status commands first to confirm the CLI runs, then configure notifications from the REPL if your workflow needs them.
Native PowerShell smoke path:
```powershell
Set-Location .\claw-code\rust
.\target\debug\claw.exe
# inside the REPL:
/notifications
```
WSL smoke path:
```bash
cd claw-code/rust
./target/debug/claw
# inside the REPL:
/notifications
```
When moving between PowerShell and WSL, keep provider keys in the environment where `claw` is actually running; Windows user env vars set with `setx` are not automatically the same as WSL shell exports.
## Troubleshooting checklist
-`claw` not found: use `claw.exe` on Windows or run the binary by full path (`.\target\debug\claw.exe`).
-`cargo` not found: reopen PowerShell after installing Rust from <https://rustup.rs/>.
-`401 Invalid bearer token`: put `sk-ant-*` values in `ANTHROPIC_API_KEY`, not `ANTHROPIC_AUTH_TOKEN`.
- Wrong provider selected: add an explicit model prefix such as `openai/gpt-4.1-mini`, `qwen-plus`, or `grok`.
- Release ZIP extracted but command still fails: open a new terminal after updating the user `Path`, or call `& "$env:LOCALAPPDATA\Programs\claw\claw.exe"` directly.
