## Conflict Resolution
**security vs axiom-build**: When build fails with signing errors:
- Code signing errors (certificate, profile, entitlement) → **use security**
- Environment issues (Xcode version, simulator, Derived Data) → **use axiom-build**
- If unsure, check the error message: `CODESIGN`, `ITMS-90xxx`, `errSec` → **security**
**security vs shipping**: When preparing for App Store:
- Privacy manifests, submission checklists, rejections → **use shipping**
- Code signing for distribution, certificate management → **use security**
**security vs axiom-data**: When storing sensitive data:
- Tokens, passwords, API keys → **use security** (keychain)
- User preferences, non-sensitive settings → **use axiom-data** (UserDefaults/SwiftData)
- File encryption levels for database files → **use security** (file-protection-ref)
- SQLite-specific Data Protection (`.db`/`-wal`/`-shm` trio, widget-while-locked access) → See axiom-data (skills/grdb-app-groups.md) §4
**security vs axiom-networking**: When securing network communication:
- TLS configuration, certificate pinning → **use axiom-networking**
- Signing API requests, encrypting payloads → **use security** (CryptoKit)
## Critical Patterns
**Keychain** (`skills/keychain.md`):
- SecItem mental model: uniqueness constraints, data protection classes
- Biometric access control (Face ID / Touch ID)
- Keychain sharing between app and extensions
- Background access pitfalls, Mac keychain differences
- Migration from UserDefaults/@AppStorage for sensitive data
**Keychain API** (`skills/keychain-ref.md`):
- SecItemAdd/CopyMatching/Update/Delete signatures
- Item class attributes, uniqueness constraint rules
- kSecAttrAccessible levels and when each applies
- Access control flags, biometric integration
- Complete error code reference
**Keychain Diagnostics** (`skills/keychain-diag.md`):
- errSecDuplicateItem from unexpected uniqueness constraints
- errSecItemNotFound despite item existing (query mismatch)
- errSecInteractionNotAllowed in background contexts
- Access group and entitlement mismatches
- Items disappearing after app updates
**CryptoKit** (`skills/cryptokit.md`):
- AES-GCM and ChaChaPoly authenticated encryption
- ECDSA/EdDSA digital signatures
- Secure Enclave hardware-backed keys
- Key agreement (ECDH) for end-to-end encryption
- HPKE for modern asymmetric encryption
- Post-quantum algorithms (ML-KEM, ML-DSA)
- CommonCrypto migration path
**CryptoKit API** (`skills/cryptokit-ref.md`):
- Hash functions (SHA-256/384/512, SHA-3), HMAC
- Symmetric encryption (AES-GCM, ChaChaPoly)
- Asymmetric signing (P256, P384, P521, Curve25519, Ed25519)
- Key agreement, key derivation (HKDF)
- Secure Enclave key creation and usage
- Swift Crypto cross-platform parity
**Passkeys** (`skills/passkeys.md`):
- ASAuthorizationController registration and assertion flows
- AutoFill-assisted requests (QuickType bar integration)
- Automatic passkey upgrades for existing users (iOS 18+)
- Combined credential requests (passkey + password + Sign in with Apple)
- Associated domains configuration for WebAuthn
**App Attest** (`skills/app-attest.md`):
- DCAppAttestService attestation and assertion flows
- Server-side validation of attestation objects
- macOS support + tampering signals (extensions, key access control) from the 27 cycle
- Fraud metric as an investigation signal
- DeviceCheck 2-bit per-device state
- Gradual rollout strategies for large install bases
- Handling unsupported devices gracefully
**Agentic Security** (`skills/agentic-security.md`):
- Threat modeling agentic features (indirect prompt injection, Lethal Trifecta)
- Deterministic vs probabilistic mitigations (redaction, spotlighting, confirmation, unlock gating)
- Foundation Models lifecycle modifiers (.onToolCall confirmation, .historyTransform)
- App Intents authenticationPolicy and schema risk metadata
**File Protection** (`skills/file-protection-ref.md`):
- NSFileProtection levels (complete, completeUnlessOpen, afterFirstUnlock, none)
- Hardware-accelerated encryption tied to device passcode
- Background file access requirements
- Keychain vs file protection comparison
**Code Signing** (`skills/code-signing.md`):
- Automatic vs manual signing tradeoffs
- Certificate and profile management across teams
- fastlane match for team-wide certificate sharing
- CI/CD signing setup (GitHub Actions, Xcode Cloud)
- Distribution build preparation (App Store, TestFlight, Ad Hoc)
**Code Signing Diagnostics** (`skills/code-signing-diag.md`):
- Certificate issues (expired, missing, wrong type, revoked)
- Provisioning profile issues (expired, missing cert, wrong App ID)
- Entitlement mismatches (capability in Xcode but not in profile)
- Keychain issues in CI (locked keychain, errSecInternalComponent)
- Archive/export failures (wrong export method, wrong cert type)
**Code Signing CLI** (`skills/code-signing-ref.md`):
- `security find-identity`, `security cms -D` for profile inspection
- `codesign -d --entitlements` for entitlement extraction
- Certificate types, validity periods, per-account limits
- fastlane match commands and Keychain management
## Automated Scanning
**Security audit** → Launch `security-privacy-scanner` agent (scans for hardcoded credentials, insecure token storage, Privacy Manifest coverage gaps, ATS violations, missing ATT descriptions, missing export compliance, weak Keychain ACLs, and compound rejection risks; scores posture HARDENED/GAPS/VULNERABLE)

Review before install: Avoid automatic install
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
