Major art movements and their historical context for art education. Covers 12 movements from the Renaissance to contemporary art, their defining characteristics, key artists, signature works, and the intellectual/social forces that produced them. Use when analyzing artworks in historical context, understanding stylistic lineages, identifying influences across periods, or connecting studio practice to art-historical precedent.

Service architecture is the discipline of decomposing a large system into cooperating services with explicit contracts, operational boundaries, and failure isolation. The goal is not to have as many s

Triggers for automatically invoking the decision-framework skill before irreversible or high-blast-radius operations. Use as a checkpoint: when a proposed action matches a trigger pattern, pause and run the appropriate framework (first-principles, inversion, decision matrix, second-order thinking) before proceeding. Prevents ad-hoc calls from becoming regret.

LaTeX document authoring with arXiv submission best practices, Overleaf patterns, and academic publishing conventions.

Provides FinOps practices for cloud cost optimization, budget management, and resource rightsizing. Use when analyzing cloud spend, optimizing costs, or when user mentions 'finops', 'cloud cost', 'rightsizing', 'budget', 'cost allocation', 'reserved instance', 'spot instance', 'showback', 'chargeback'.

Provides GitOps best practices for ArgoCD, Flux, Argo Rollouts, and progressive delivery strategies. Use when setting up GitOps workflows, configuring continuous delivery, managing Kubernetes deployments declaratively, or when user mentions 'gitops', 'argocd', 'flux', 'progressive delivery', 'reconciliation', 'argo rollouts', 'canary', 'sealed secrets'.

Agile and Lean software development methodologies for iterative, adaptive project execution. Covers Scrum (roles, ceremonies, artifacts), Kanban (WIP limits, flow metrics), XP (TDD, pair programming, CI), SAFe overview, Lean Software Development (Poppendieck's 7 principles), user stories (INVEST criteria), estimation via story points and velocity, and the Agile Manifesto's values and principles. Includes Cynefin framework for methodology selection and GSD's relationship to Agile as a structured Lean variant.

A postmortem is the work product that converts an incident from a surprise into learning. A *blameless* postmortem does this without punishing the people closest to the incident — not because punishme

Fact-checking and source verification workflow for research documents. Launches parallel fact-checkers, aggregates findings, applies corrections systematically.

Apprenticeship pedagogy for the trades — how craft is actually taught, which is almost nothing like how classroom subjects are taught. Covers the observe/practice/correct loop, the role of the master as model rather than lecturer, the ladder from sweeping the shop to working on real jobs, the honest handling of failure, and the modern adaptations of apprenticeship for contexts where a traditional master-apprentice relationship is not available. Use when designing a training program, diagnosing why a trainee is stuck, or understanding why textbook learning falls short in craft domains.

Tools and machines as the leverage-amplification layer of the trades — how hand tools, powered tools, and programmable machines differ in what they amplify, what they constrain, and what skill they demand. Covers the tool-to-machine progression, the Nasmyth steam-hammer lineage of precision power, the block-making machinery at Portsmouth as the first mass-production machine shop, and the modern CNC/robotics layer. Use when selecting tools for a job, justifying a tool purchase, or teaching a learner why tools are organized the way they are.

Deterministic git operations with state verification for skill-creator managed repos. Use when managing repos, branches, worktrees, or contribution workflows.

Complex systems and emergent behavior — chaos theory, fractals, neural networks, cellular automata, and computability. Analyzes dynamical systems for chaos via Lyapunov exponents, classifies bifurcations, measures fractal dimension, and models emergent phenomena. Use when analyzing chaotic systems, computing Lyapunov exponents, classifying bifurcations, measuring fractal dimension, modeling neural networks, or studying emergent behavior from simple rules.

Use trace-mcp apply_codemod for any bulk mechanical change instead of repeated Edit calls. Activate whenever the same edit pattern would be applied 2+ times, across one file or many.

Defense-in-depth security for AI-assisted development. Pre-commit secret scanning (Gitleaks + native fallback), repo-wide pattern detection, token lifecycle management, and AI agent safety rules. Prevents secret leaks at every stage: write → commit → push → deploy. Use BEFORE any git push or deploy, or when setting up new projects.

Pre-production security audit and vulnerability scanning. Run Snyk + Aikido dependency scans, OWASP analysis, and set up automated GitHub security checks with Jules. Use when asked to 'run security check', 'security audit', 'kiểm tra bảo mật', 'vulnerability scan', 'Snyk', 'OWASP', or before open-sourcing / commercializing a project.

Start the CM Workflow to execute your objective from idea to production code.

You are the **Chair** — John Carmack's philosophy made operational. You coordinate a council of domain experts, each running as an independent subagent via the `Task` tool. Your job is to understand t
