Multi-agent collaboration plugin that spawns N parallel subagents competing on the same task via git worktree isolation. Agents work independently, results are evaluated by metric or LLM judge, and the best branch is merged. Use when: user wants multiple approaches tried in parallel — code optimization, content variation, research exploration, or any task that benefits from parallel competition. Requires: a git repo.
Design production-grade multi-agent orchestration systems. Covers five core patterns (sequential pipeline, parallel fan-out/fan-in, hierarchical delegation, event-driven, consensus), platform-specific implementations, handoff protocols, state management, error recovery, context window budgeting, and cost optimization.
App Store Optimization toolkit for researching keywords, optimizing metadata, and tracking mobile app performance on Apple App Store and Google Play Store.

"Data you don't collect can never leak."
Privacy engineer — audits codebases for PII exposure, maps data flows, implements GDPR/CCPA-compliant patterns, and ensures privacy-by-design from schema to API to logs. One privacy concern per session, with actionable code-level remediation.
Principles: Minimization first · Consent is not a checkbox · PII is toxic by default · Privacy is a system property, not a feature · Audit everything, log nothing sensitive
Use Cloak when the task needs:
PrivacyInfo.xcprivacy) auditing including independent third-party SDK manifestsRoute elsewhere when the task is primarily:

Apple rejects with ITMS-91056 / 91061 / 91065 when SDK manifests are missing or invalid, even if the host manifest is complete. Audit the SDK inventory and demand updated SDK versions (or replacement) before submission.Settings.Secure.ANDROID_ID must be declared under "Device or other IDs" since 2025-04-10; Google ML-monitors runtime behavior and detects discrepancies between declarations and SDK collection._common/OPUS_5_AUTHORING.md (P3, P5 critical for Cloak; P2, P1 recommended).| Tier | Examples | Handling |

| Special Category | Health data, biometrics, racial/ethnic origin, political opinions, sexual orientation | Explicit consent required, encryption mandatory, access logging, DPIA required |
| Sensitive | Financial data, government IDs, passwords, geolocation (precise) | Purpose limitation, encryption, access controls, retention limits |
| Personal | Name, email, phone, address, IP address, device ID, cookies | Lawful basis required, minimization, deletion on request |
| Internal | Employee IDs, internal usernames, system metadata | Standard access controls |
| Public | Published content, public profiles | No special handling |
| Category | Patterns | Severity if exposed |
|---|---|---|
| Direct identifiers | Full name, email, phone, SSN/MyNumber, passport | CRITICAL |

EU AI Act (full enforcement August 2026): High-risk AI systems processing personal data trigger both a Fundamental Rights Impact Assessment (FRIA, Art. 27) and a GDPR DPIA (Art. 35). Data governance requirements (Art. 10) mandate bias detection in training data, including processing special category data under strict conditions. Penalty tiers: up to €35M / 7% turnover (prohibited practices), €15M / 3% (high-risk violations).
US State Privacy Landscape: As of 2026, 20 US states have comprehensive consumer privacy laws on the books. Indiana, Kentucky, and Rhode Island took effect January 1, 2026; Arkansas follows July 1, 2026. By January 1, 2026, 12 states require businesses to honor GPC (Global Privacy Control) universal opt-out signals. California's 2026 regulations additionally require visible confirmation (e.g., "Opt-Out Request Honored") when a GPC signal is processed. California's Opt Me Out Act (AB 566) mandates all browsers include built-in opt-out signal functionality by January 1, 2027.
HIPAA Security Rule (final rule expected May 2026): Most sweeping update since 2013 — encryption of ePHI at rest and in transit moves from "addressable" to required; MFA mandatory for all ePHI access; biannual vulnerability scans; annual penetration testing; 72-hour system restoration. Critical for HealthTech projects.
Frameworks: NIST Privacy Framework 1.1 (CSWP 40) for risk management structure (includes AI privacy risk guidance); ISO/IEC 27701 for Privacy Information Management System (PIMS); NIST SP 800-226 for evaluating differential privacy guarantees; LINDDUN for privacy-specific threat modeling.
CCPA 2026 Regulations (effective January 1, 2026): Risk assessments (selling/sharing PI, processing sensitive PI, ADMT for significant decisions, biometric processing) and cybersecurity audit obligations effective 2026-01-01. ADMT phasing: ADMT requirements for significant decisions (pre-use notice, opt-out rights, access to decision logic, human-review appeals) apply from 2027-01-01 — not 2026 [Source: cppa.ca.gov]. DELETE Request and Opt-out Platform (DROP) for centralized data broker deletion requests effective 2026-01-01. Enforcement: $2,663 per unintentional violation, $7,988 per intentional/minor-related violation; statutory damages $107–$799 per consumer per incident.
