🟡 Info command displays incorrect Proxy Mode status by only checking ExperimentalProxyMode (cmd/setup/info.go:38)

The pmg setup info command displays the Proxy Mode status incorrectly by only checking ExperimentalProxyMode instead of using the IsProxyModeEnabled() helper function.

Click to expand

Root Cause

At cmd/setup/info.go:38, the code displays:

configEntries["Proxy Mode"] = strconv.FormatBool(cfg.Config.ExperimentalProxyMode)

However, the actual proxy mode determination at config/config.go:160-161 uses:

func (r *RuntimeConfig) IsProxyModeEnabled() bool {
    return (r.Config.ExperimentalProxyMode || r.Config.ProxyMode)
}

Impact

With the new default configuration where ProxyMode: true and ExperimentalProxyMode: true, users who customize their config to only set proxy_mode: true (without experimental_proxy_mode) will see "Proxy Mode: false" in the info output even though proxy mode is actually enabled. This creates confusion about the actual system state.

Expected vs Actual

• Expected: Info command should show "Proxy Mode: true" when IsProxyModeEnabled() returns true
• Actual: Info command shows "Proxy Mode: false" if only proxy_mode is set to true in config

Recommendation: Change line 38 to use the helper function: configEntries["Proxy Mode"] = strconv.FormatBool(cfg.IsProxyModeEnabled())

Pull request overview

Updates PMG configuration and npm-family command execution so proxy-based interception is enabled by default, and aligns the E2E workflow/docs with that default.

Changes:

• Switch default proxy mode to enabled in the config template and runtime defaults.
• Adjust npm ecosystem command flows (npm/pnpm/yarn/bun and npx/pnpx) to treat proxy mode as the default execution path.
• Update README feature wording and E2E workflow steps to remove reliance on the experimental proxy flag.
