Revyl iOS Auth Bypass Skill

Use this leaf skill when revyl-cli-auth-bypass has selected a native iOS app. This is app code guidance, not a Revyl authentication shortcut.

For the first-pass setup, start from revyl-cli-auth-bypass; it detects the stack, applies the shared safety contract, and delegates here for Swift/iOS implementation details.

Native Agent Behavior

• Ask at most 1-3 concise clarification questions only when the target app, platform, session, URL scheme, token source, or sensitive action cannot be inferred from the repo or Revyl CLI.
• Prefer safe defaults and keep moving when app source, revyl dev list, screenshots, or reports can answer the question.
• When Revyl prints a viewer or local app URL, open it in the native browser/tool surface when available: Codex Browser/in-app browser for local URLs, Revyl viewer URLs, screenshots, and page checks; Claude Code .claude/skills slash-command discovery plus WebFetch/WebSearch or configured MCP/browser tools; Cursor .cursor/skills plus .cursor/rules/revyl-skills.mdc and available MCP/browser tools.
• If no browser tool is exposed, report the URL and verify through revyl device screenshot or revyl device report instead of claiming browser access.
• Confirm before entering sensitive data, submitting forms, uploading files, accepting browser permissions, changing sharing/access, or deleting data.

Contract

Use one app-specific deep link shape:

myapp://revyl-auth?token=<token>&role=<role>&redirect=<allowlisted-route>

Revyl launch variables arrive in iOS simulator apps as launch arguments, for example:

-REVYL_AUTH_BYPASS_ENABLED true -REVYL_AUTH_BYPASS_TOKEN <token>

Files To Add Or Update

• Info.plist: register the app URL scheme.
• SwiftUI app root or app/scene delegate: handle myapp://revyl-auth.
• Auth/session module: create the normal app session for an allowlisted role.
• Router/coordinator: route only to allowlisted destinations.
• Account, debug, or settings screen: show accepted/rejected auth-bypass state in test builds.

URL Scheme

Register an app-specific scheme such as myapp in Info.plist:

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>myapp</string>
    </array>
  </dict>
</array>

Swift Handler

Keep session creation app-specific and explicit:

import Foundation

private let allowedRedirects: [String: AppRoute] = [
    "/account": .account,
    "/checkout": .checkout,
    "/cart": .cart
]
private let allowedRoles: Set<String> = ["buyer", "support"]

func launchValue(_ key: String) -> String? {
    let args = ProcessInfo.processInfo.arguments
    guard let index = args.firstIndex(of: "-\(key)") else { return nil }
    let valueIndex = args.index(after: index)
    return args.indices.contains(valueIndex) ? args[valueIndex] : nil
}

func queryValue(_ name: String, in url: URL) -> String? {
    let items = URLComponents(url: url, resolvingAgainstBaseURL: false)?.queryItems ?? []
    return items.first(where: { $0.name == name })?.value
}

func handleRevylAuthBypass(_ url: URL) throws -> Bool {
    guard url.scheme == "myapp", url.host == "revyl-auth" else { return false }

    guard launchValue("REVYL_AUTH_BYPASS_ENABLED") == "true" else {
        throw AuthBypassError.disabled
    }
    guard queryValue("token", in: url) == launchValue("REVYL_AUTH_BYPASS_TOKEN") else {
        throw AuthBypassError.badToken
    }

    let role = queryValue("role", in: url) ?? "buyer"
    let redirect = queryValue("redirect", in: url) ?? "/account"
    guard allowedRoles.contains(role) else { throw AuthBypassError.badRole }
    guard let route = allowedRedirects[redirect] else { throw AuthBypassError.badRedirect }

    TestSession.signIn(role: role)
    AppRouter.shared.navigate(to: route)
    return true
}

Call the handler from SwiftUI or app delegate URL handling:

.onOpenURL { url in
    do {
        if try handleRevylAuthBypass(url) {
            AuthBypassStatus.shared.accepted()
        }
    } catch {
        AuthBypassStatus.shared.rejected(String(describing: error))
    }
}

Replace TestSession, AppRouter, AppRoute, and AuthBypassStatus with the app's real session and UI surfaces.

Verification

Start a fresh Revyl session with launch vars attached:

export REVYL_AUTH_BYPASS_TOKEN="<test-only-token>"
revyl global launch-var update REVYL_AUTH_BYPASS_TOKEN --value "$REVYL_AUTH_BYPASS_TOKEN"

revyl dev --platform ios --no-build \
  --launch-var REVYL_AUTH_BYPASS_ENABLED \
  --launch-var REVYL_AUTH_BYPASS_TOKEN

Then verify valid and rejected links:

revyl device navigate --url "myapp://revyl-auth?token=$REVYL_AUTH_BYPASS_TOKEN&role=buyer&redirect=%2Fcheckout"
revyl device screenshot --out /tmp/revyl-auth-bypass-ios-valid.png

revyl device navigate --url "myapp://revyl-auth?token=wrong-token&role=buyer&redirect=%2Fcheckout"
revyl device navigate --url "myapp://revyl-auth?token=$REVYL_AUTH_BYPASS_TOKEN&role=admin&redirect=%2Fcheckout"
revyl device navigate --url "myapp://revyl-auth?token=$REVYL_AUTH_BYPASS_TOKEN&role=buyer&redirect=%2Fadmin"
revyl device screenshot --out /tmp/revyl-auth-bypass-ios-rejected.png

Guardrails

1. Never ship an unconditional production bypass.
2. Gate by simulator/debug/staging/test build plus REVYL_AUTH_BYPASS_ENABLED=true.
3. Never put raw tokens in source, YAML, screenshots, or PR copy.
4. Keep role and redirect allowlists small and app-specific.
5. Show rejected state visibly in the app so the agent can diagnose failures.
