AB capacitor-ios-security-hardening

Audits and progressively hardens Xcode security build settings for a Capacitor iOS app (ios/App/App.xcodeproj, scheme App) and native plugin code (Swift/ObjC/C, Package.swift, podspec). Covers `xcodebuild -showBuildSettings -json`, security compiler warnings, static analyzer checkers (`xcodebuild analyze`), Xcode Enhanced Security (ENABLE_ENHANCED_SECURITY, com.apple.security.hardened-process entitlements, pointer authentication / arm64e, memory tagging soft mode), what is safe for a WKWebView hybrid app vs what breaks CocoaPods, SPM binary xcframeworks or Cordova plugins, staged adoption, and a decision log. Use for "harden my iOS build", "enable Enhanced Security", security build settings audit, arm64e link errors after enabling pointer authentication, or Build and Analyze setup. Do not use for ATS/TLS, signing, secrets or WebView rules (capacitor-security), or App Store review (capacitor-apple-review-preflight).

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Process rating: all ten parameters 67/100

    • 0Result and completion. Does not say what the result is
    • 0Inputs and preconditions. Does not say what the process needs to start
    • 30Running it twice. 7 mutating operations with no state check
    • 50Failures and branches. 0 branches, has a failure section

    • 100Progress reporting. Reports progress

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
