+# ClaudeX Proxy Setup
+
+Idempotent Windows setup for running Claude Code through [CLIProxyAPI](https://github.com/router-for-me/CLIProxyAPI) with Codex OAuth authentication.
+
+The script installs and configures the proxy, adds a `claudex` PowerShell command with model aliases, and keeps the proxy running through Task Scheduler.
+
+## What it does
+
+`setup-claudex-proxy.ps1`:
+
+- Checks whether the `claude` command is installed.
+- Installs Claude Code through its Windows installer when missing.
+- Downloads CLIProxyAPI `v7.2.71` for Windows x64.
+- Extracts it into:
+
+  ```text
+  C:\Program Files\CLIProxyAPI_7.2.71_windows_amd64
+  ```
+
+- Creates a localhost-only `config.yaml` on port `8317`.
+- Stores Codex OAuth credentials under:
+
+  ```text
+  %USERPROFILE%\.cli-proxy-api
+  ```
+
+- Adds a managed `claudex` function to Windows PowerShell and PowerShell 7 profiles.
+- Adds the model aliases `sol`, `terra`, and `luna`.
+- Opens Codex OAuth login only when no existing Codex credential is detected.
+- Creates or updates a Task Scheduler task named `CLIProxyAPI`.
+- Starts the proxy at boot under the current Windows user.
+- Restarts the proxy if it exits.
+- Verifies that port `8317` is listening.
+- Skips completed steps when rerun.
+
+## Requirements
+
+- Windows 10 or Windows 11, x64
+- PowerShell 5.1 or newer
+- Administrator access
+- Internet access
+- A ChatGPT account with Codex access
+
+The script automatically requests elevation through UAC.
+
+## Installation
+
+Download or clone the repository, then open PowerShell in the repository directory:
+
+```powershell
+Unblock-File .\setup-claudex-proxy.ps1
+powershell -ExecutionPolicy Bypass -File .\setup-claudex-proxy.ps1
+```
+
+The script may open a browser for Codex OAuth authentication.
+
+After setup finishes, open a new PowerShell window.
+
+## Usage
+
+Run Claude Code using one of the configured aliases:
+
+```powershell
+claudex sol
+claudex terra
+claudex luna
+```
+
+Additional Claude Code arguments are passed through:
+
+```powershell
+claudex sol --dangerously-skip-permissions
+```
+
+A complete model name can also be used directly:
+
+```powershell
+claudex gpt-5.6-sol
+```
+
+The default model is `sol`, so this also works:
+
+```powershell
+claudex
+```
+
+## Options
+
+Force CLIProxyAPI to be downloaded and installed again:
+
+```powershell
+.\setup-claudex-proxy.ps1 -ForceReinstall
+```
+
+Skip the interactive Codex login:
+
+```powershell
+.\setup-claudex-proxy.ps1 -SkipCodexLogin
+```
+
+Configure everything without starting the scheduled task:
+
+```powershell
+.\setup-claudex-proxy.ps1 -NoStart
+```
+
+Options can be combined:
+
+```powershell
+.\setup-claudex-proxy.ps1 -ForceReinstall -NoStart
+```
+
+## Files created
+
+```text
+C:\Program Files\CLIProxyAPI_7.2.71_windows_amd64\
+├── cli-proxy-api.exe
+├── config.yaml

+├── proxy-watchdog.log
+└── logs\
+```
+
+PowerShell profile blocks are written to the applicable paths below:
+
+```text
+Documents\WindowsPowerShell\profile.ps1
+Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1
+Documents\PowerShell\profile.ps1
+Documents\PowerShell\Microsoft.PowerShell_profile.ps1
+```
+
+The generated section is wrapped in markers so rerunning the setup updates it instead of duplicating it.
+
+## Task Scheduler
+
+The script creates a task named:
+
+```text
+CLIProxyAPI
+```
+
+Check its status:
+
+```powershell
+Get-ScheduledTask -TaskName CLIProxyAPI
+Get-ScheduledTaskInfo -TaskName CLIProxyAPI
+```
+
+Start or stop it manually:
+
+```powershell
+Start-ScheduledTask -TaskName CLIProxyAPI
+Stop-ScheduledTask -TaskName CLIProxyAPI
+```
+
+Check whether the proxy is listening:
+
+```powershell
+Test-NetConnection 127.0.0.1 -Port 8317
+```
+
+## Custom model aliases
+
+Edit the managed alias table in your PowerShell profile:
+
+```powershell
+$global:ClaudeModelAliases = @{
+    sol   = 'gpt-5.6-sol'
+    terra = 'gpt-5.6-terra'
+    luna  = 'gpt-5.6-luna'
+}
+```
+
+Then reload the current profile:
+
+```powershell
+. $PROFILE
+```
+
+Rerunning the setup script restores the aliases defined inside the installer.
+
+## Re-running and existing installations
+
+The setup is intended to be idempotent:
+
+- Existing Claude Code installations are skipped.
+- Existing CLIProxyAPI binaries are skipped unless `-ForceReinstall` is used.
+- Existing Codex credentials are reused.
+- The scheduled task is replaced only when its configuration differs.
+- Managed PowerShell profile blocks are updated in place.
+- A different existing `config.yaml` is backed up before replacement.
+
+Configuration backups use names such as:
+
+```text
+config.yaml.bak-20260712-193000
+```
+
+## Troubleshooting
+
+### `claudex` is not recognized
+
+Open a new PowerShell window or reload the profile:
+
+```powershell
+. $PROFILE
+```
+
+### Port 8317 is not listening
+
+Check the scheduled task and logs:
+
+```powershell
+Get-ScheduledTaskInfo -TaskName CLIProxyAPI
+Get-Content "C:\Program Files\CLIProxyAPI_7.2.71_windows_amd64\proxy-watchdog.log" -Tail 100
+```
+
+CLIProxyAPI application logs are stored under:
+
+```text
+C:\Program Files\CLIProxyAPI_7.2.71_windows_amd64\logs
+```
+
+### OAuth login needs to be repeated
+
+Run:
+
+```powershell
+& "C:\Program Files\CLIProxyAPI_7.2.71_windows_amd64\cli-proxy-api.exe" `
+  -config "C:\Program Files\CLIProxyAPI_7.2.71_windows_amd64\config.yaml" `
+  -codex-login
+```
+
+Then restart the task:
+
+```powershell
+Stop-ScheduledTask -TaskName CLIProxyAPI
+Start-ScheduledTask -TaskName CLIProxyAPI
+```
+
+### Remove the scheduled task
+
+```powershell
+Unregister-ScheduledTask -TaskName CLIProxyAPI -Confirm:$false
+```
+
+The installation directory, OAuth credentials, and profile block must be removed separately.
+
+## Security and compatibility
+
+The generated proxy configuration binds only to `127.0.0.1`. Do not expose port `8317` to your LAN or the public internet without proper authentication and network controls.
