# Web Environment Setup

You are helping set up the Umbraco.AI repository for building in Claude Code web environment.

## Task

Run the web environment setup script to prepare the environment for .NET development.

## Quick Start

```bash
# One-command setup
source .claude/scripts/setup-web-environment.sh

# Build
dotnet build Umbraco.AI.sln
```

## Workflow

1. **Run the setup script**:

    ```bash
    source .claude/scripts/setup-web-environment.sh
    ```

2. **Verify the setup** by checking:
    - `dotnet --version` returns 10.x
    - Proxy environment variables are set
    - Git is not a shallow clone

3. **Test the build**:
    ```bash
    dotnet build Umbraco.AI.sln
    ```

## Problem

Claude Code web runs in a sandboxed environment with restrictions:

1. **Proxy Authentication** - Network requests go through a JWT-authenticated proxy
2. **Package Feed Restrictions** - Only certain hosts are allowed (e.g., `api.nuget.org` but not `www.myget.org`)
3. **Shallow Git Clones** - May break Nerdbank.GitVersioning
4. **.NET SDK** - May not be pre-installed

## Scripts

| Script                     | Purpose                   | Usage                                             |
| -------------------------- | ------------------------- | ------------------------------------------------- |
| `setup-web-environment.sh` | Full environment setup    | `source .claude/scripts/setup-web-environment.sh` |
| `setup-dotnet-proxy.sh`    | Proxy + NuGet config only | `source .claude/scripts/setup-dotnet-proxy.sh`    |
| `dotnet-with-proxy.sh`     | Run dotnet with proxy     | `.claude/scripts/dotnet-with-proxy.sh restore`    |

## What `setup-web-environment.sh` Does

1. **Installs .NET SDK 10.0** via apt (if not present)
2. **Starts px-proxy** to handle JWT-authenticated proxy for NuGet
3. **Creates user-level NuGet.Config** that uses only `api.nuget.org` (bypasses restricted MyGet feeds)
4. **Unshallows git clone** so Nerdbank.GitVersioning can calculate version height

## Environment Detection

All scripts automatically detect if they're running in Claude Code web by checking for JWT proxy patterns:

```bash
if [[ "$HTTP_PROXY" =~ "jwt_" ]] && [[ "$HTTP_PROXY" =~ "@" ]]; then
    # Claude Code web environment - run setup
else
    # Local environment - do nothing
fi
```

| Environment             | `HTTP_PROXY` value               | Detection       |
| ----------------------- | -------------------------------- | --------------- |
| Claude Code web         | `http://...jwt_eyJ...@host:port` | ✅ Detected     |
| Local (no proxy)        | _(unset)_                        | ❌ Not detected |
| Local (corporate proxy) | `http://proxy.corp:8080`         | ❌ Not detected |

**On local machines, the scripts do nothing** - they're safe to run anywhere.

## Troubleshooting

| Issue                | Solution                                   |
| -------------------- | ------------------------------------------ |
| Proxy errors         | Check `/tmp/px-proxy.log`                  |
| NuGet restore fails  | Verify proxy: `pgrep -f px`                |
| GitVersioning errors | Run `git fetch --unshallow origin`         |
| MyGet warnings       | Safe to ignore - nuget.org is used instead |

```

The px-proxy handles the JWT authentication transparently, allowing standard .NET tooling to work through the sandbox proxy.
