Chiropractic practice operations & compliance team — agents (chiropractic-practice-lead, chiro-billing-compliance-specialist) across the two engines of a DC office: the practice (capacity & scheduling to the care plan, the cash / insurance / wellness-plan model, membership pricing, patient-visit-average & plan-completion retention) and coding/compliance (CMT vs E&M by region, documented medical necessity via the PART exam, the active-vs-maintenance plateau call, ABN workflow, audit-defensible notes). skills, a decision-tree knowledge bank (a billing-and-medical-necessity Mermaid tree + a dated 2026 payer/coding reference), best-practices. Operations & coding decision-support, NOT medical/legal/billing advice and NOT a coding certification; no PHI; scope/coverage/coding rules are state/payer-specific + volatile — retrieval-dated + verify-at-use, flagged for a licensed professional. Seams: physical-therapy-rehab-clinic, medical-revenue-cycle. Requires ravenclaude-core@>=0.7.0.

Data governance & privacy team — agents (data-governance-architect, privacy-compliance-engineer, data-catalog-lineage-engineer) for making data discoverable, trustworthy, and lawfully used: the governance operating model (ownership/stewardship, policies, classification scheme), privacy mechanics (GDPR/CCPA/-style data-subject rights — access/erasure/portability, consent + lawful basis, data minimization, retention, pseudonymization vs anonymization), and a data catalog with lineage + sensitive-data/PII discovery + access governance/DLP. The ENGINEERING of governance, not legal advice. skills, a decision-tree knowledge bank (classification + DSR-handling trees + a dated 2026 map), best-practices, templates, commands, an advisory hook. Seams: financial-regulatory -> regulatory-compliance, warehouse RLS -> data-platform, Purview-in-Fabric -> microsoft-fabric, security verdicts -> security-engineering. Requires ravenclaude-core@>=0.7.0.

E-commerce & DTC specialist team — agents (ecommerce-lead, merchandising-specialist, performance-marketing-strategist, retention-analytics-analyst), skills, templates, commands, an advisory hook, best-practice rules, and a research-grounded knowledge bank. A growth-and-unit-economics team for a DTC brand operator — it protects the LTV:CAC ratio (the 3:1 line below which a brand bleeds), reads conversion against the 1.4–1.8% average, attacks the retention gap (the average brand keeps just ~28% for a second purchase), and reads contribution margin after the real cost of acquisition and returns. Inherits ravenclaude-core protocols.

Game Development specialist team — agents (gamedev-producer, game-designer, gameplay-engineer, live-ops-analyst), skills, templates, commands, an advisory hook, best-practice rules, a research-grounded knowledge bank with Mermaid decision trees (production/design/live-ops + runtime-performance frame/GC/draw-call/memory budgets + engine-selection/ECS-vs-OOP/networking-model), a scenarios bank (frame-time GC hitch, draw-call batching, netcode rollback, save-system migration), a stdlib frame/CPU-GPU/memory budget calculator (scripts/gamedev_budget.py), and a bundled C# (Roslyn, stdio) LSP config. Scopes to a vertical slice, designs core loops and economies that retain, runs production on milestones and risk burn-down, reads live-ops on retention/monetization, and diagnoses frame-budget/draw-call/netcode/save-migration problems. Inherits ravenclaude-core protocols.

Higher-education administration operations team — agents (higher-ed-administration-lead, enrollment-management-strategist, student-success-advisor) across the three engines of a college/university admin operation: institutional strategy (enrollment strategy, the budget/net-tuition-revenue model, retention/completion, cross-functional coordination, accreditation), enrollment management (the inquiry->apply->admit->yield->melt funnel, yield & discount-rate modeling, financial-aid leveraging), and student success (persistence, early-alert, advising, at-risk intervention, DFW-course analysis). Ships skills, a decision-tree knowledge bank (Mermaid trees + a dated 2026 reference), best-practices, templates, commands. ADVISORY operations knowledge, not legal, financial-aid-compliance, or academic-policy advice; volatile specifics (funnel benchmarks, discount-rate norms, metric definitions) carry a retrieval date + verify-at-use; FERPA-aware — no student PII. Requires ravenclaude-core@>=0.7.0.

Memory engineering team — agents (memory-architect-lead, memory-retention-and-erasure-engineer, memory-eval-cost-analyst) for the decisions behind a durable memory store: what earns a write, which paradigm, which surface holds the bytes, what makes it forget, what a delete leaves behind, cost per correct answer. skills, commands, dated knowledge files, best-practices, templates, scenarios, an advisory hook, a stdlib calculator. Advisory only — it never reads or mutates a real store. Seams: ai-agent-engineering decides whether an agent should remember at all and where state sits in its topology, this engineers the memory system itself; ai-red-teaming owns the ASI06 attack taxonomy and offensive testing, this owns the defensive design half; data-governance-privacy owns DSAR and legal basis, this owns erasure residue in embeddings and version history; retrieval → ai-rag-engineering; evals → llm-evaluation-engineering; the Claude app → claude-app-engineering. Requires ravenclaude-core@>=0.238.0.

People Operations / HR specialist team — agents (people-ops-lead, talent-acquisition-strategist, total-rewards-comp-analyst, people-analytics-engagement-specialist), skills, templates, commands, an advisory hook, best-practice rules, and a research-grounded knowledge bank. A People-Ops team for an HRBP, People-Ops leader, or founder accountable for headcount, attrition, comp, and engagement — it quantifies attrition cost and cause before acting, pays to a defensible band rather than the counteroffer, treats time-to-fill and quality-of-hire as a hiring system, and reads engagement segmented as a leading indicator of regretted exits. Inherits ravenclaude-core protocols.
