  EVA installed successfully $VERSION_INFO
  Binary: $INSTALL_DIR/$BINARY_NAME

  Note: For the full experience (agent, hooks, skills), use the plugin:
    claude plugins install theLightArchitect/EVA

  To use this standalone binary, add to Claude Code:

  1. Quick setup:

     claude mcp add EVA -- $INSTALL_DIR/$BINARY_NAME

  2. Or manually add to ~/.claude/mcp.json:

     {
       "mcpServers": {
         "EVA": {
           "command": "$INSTALL_DIR/$BINARY_NAME",
           "env": { "RUST_LOG": "info" }
         }
       }
     }

  3. Restart Claude Code, then try:

     "Hey EVA, what can you do?"
     "EVA, review this code"
