What this skill does


# Compliance Engineering

## Framework Overview

| Framework | Scope | Key Requirements |
|-----------|-------|-----------------|
| **SOC 2** | Service organizations | Security, availability, confidentiality, privacy, processing integrity |
| **HIPAA** | Healthcare data (PHI) | Encryption, access controls, audit logging, BAAs |
| **GDPR** | EU personal data | Consent, data minimization, right to erasure, DPIAs |
| **PCI-DSS** | Payment card data | Network segmentation, encryption, access controls, logging |
| **FedRAMP** | US government cloud | NIST 800-53 controls, continuous monitoring, authorization |

## SOC 2 Controls in Code

### Audit Logging
```typescript
interface AuditEvent {
  timestamp: string;
  actor: { id: string; role: string; ip: string };
  action: string;
  resource: { type: string; id: string };
  outcome: 'success' | 'failure';
  metadata: Record<string, unknown>;
}

async function auditLog(event: AuditEvent): Promise<void> {
  // Write-once, append-only storage (immutable)
  await auditStore.append({
    ...event,
    timestamp: new Date().toISOString(),
    hash: computeChainHash(event), // tamper detection
  });
}
```

### Access Control
```typescript
// RBAC with principle of least privilege
const permissions = {
  admin: ['read', 'write', 'delete', 'manage_users'],
  editor: ['read', 'write'],
  viewer: ['read'],
} as const;

function authorize(user: User, action: string, resource: Resource): boolean {
  const allowed = permissions[user.role];
  if (!allowed?.includes(action)) {
    auditLog({ action, outcome: 'failure', actor: user, resource });
    return false;
  }
  return true;
}
```

## HIPAA Technical Safeguards

- **Encryption at rest:** AES-256 for PHI storage, AWS KMS / GCP KMS for key management
- **Encryption in transit:** TLS 1.2+ mandatory, certificate pinning for mobile
- **Access controls:** Unique user IDs, automatic logoff, MFA required
- **Audit controls:** Log all PHI access, retain logs 6+ years, tamper-evident
- **Data backup:** Encrypted backups, tested restore procedures, geographic redundancy

## GDPR Implementation

### Consent Management
```typescript
interface ConsentRecord {
  userId: string;
  purpose: string;
  granted: boolean;
  timestamp: string;
  source: 'explicit' | 'legitimate_interest';
  withdrawable: boolean;
}

// Data Subject Access Request (DSAR)
async function handleDSAR(userId: string, type: 'access' | 'erasure' | 'portability') {
  switch (type) {
    case 'access': return await exportUserData(userId); // JSON/CSV
    case 'erasure': return await deleteUserData(userId); // Right to be forgotten
    case 'portability': return await exportPortableData(userId); // Machine-readable
  }
}
```

### Data Minimization
- Collect only what's needed for the stated purpose
- Set retention policies with automatic deletion
- Pseudonymize where possible (replace PII with tokens)
- Anonymize for analytics (k-anonymity, differential privacy)

## PCI-DSS Key Controls
- **Never store CVV/CVC** — ever, in any form
- **Tokenize card numbers** — use Stripe/Braintree tokens instead of raw PANs
- **Network segmentation** — isolate cardholder data environment (CDE)
- **Quarterly vulnerability scans** — ASV-approved external scans
- **Penetration testing** — annual at minimum, after significant changes

## Compliance as Code
- **Policy as code:** Open Policy Agent (OPA), AWS Config Rules, Azure Policy
- **Infrastructure compliance:** Terraform Sentinel, Checkov, tfsec
- **Runtime compliance:** Falco for container monitoring, AWS GuardDuty
- **Evidence collection:** Automated screenshot/log collection for audit evidence

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

Designscripts

react-native-skia

Included

Design, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.

Designscripts

plaid

Included

Product Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".

Designscripts

nextjs-framer-motion-animations

Included

Adds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
