The craft of being a Chief of Staff — gatekeeping, force multiplication, executive briefing, organizational sensing, institutional memory, and meeting/calendar triage. Provides the frameworks and templates that make an executive more effective by managing their capacity, information flow, and decision surface.
Use when designing, operating, reviewing, or improving production reliability with SLOs, incident command, observability, error budgets, and operational excellence.
Use when exploring adjacent ideas, overlooked angles, or lateral research paths without prematurely collapsing into a single answer.
Shared decision-making and governance methodology for all C-suite profiles. Covers decision frameworks (RAPID, DACI, decision matrices, pre-mortems, red-teaming), strategic thinking patterns (inversion, first principles, second-order effects), stakeholder communication (executive summaries, board decks, strategy memos), and governance frameworks (risk appetite, delegation levels, escalation paths).
CFO methodology for unit economics, financial modeling, pricing strategy, fundraising, budget frameworks, and SaaS metrics. Covers CAC/LTV/payback analysis, revenue projections, cost structures, runway analysis, scenario planning, value-based pricing, cap tables, term sheets, zero-based budgeting, rolling forecasts, ARR/MRR, churn, NDR, Rule of 40, and Magic Number.
CMO methodology — positioning and messaging frameworks (April Dunford's positioning, message hierarchy), customer acquisition strategy (paid, organic, PLG, SLG), brand architecture (brand house vs house of brands), growth modeling (CAC/LTV by channel, cohort analysis), market entry strategy (beachhead, land-and-expand), competitive response (pricing wars, feature races, brand defense).

Core methodology and reference library for platform engineering work. This skill does not execute operations itself — it provides the frameworks, patterns, and reference material that a platform-engineer profile loads on demand.
Load this skill when the task involves:
| Trigger | What's Needed |
|---|---|
| Design a CI/CD pipeline | Pipeline structure, GitOps sync strategies, release automation |
| Infrastructure as code plan | Terraform/OpenTofu module patterns, state management, Pulumi/Ansible patterns |
| Container orchestration design | K8s pod lifecycle, Helm chart conventions, Kustomize overlays, Docker Compose |
| Service networking / mesh | Traefik/nginx/Caddy config, Tailscale/Headscale ACL, WireGuard, service mesh |
| Observability strategy | Prometheus rules, Grafana dashboards-as-code, Loki logging, tracing |
| Secret management design | Vault, SOPS, External Secrets Operator patterns |
| Cloud architecture assessment | Multi-cloud patterns, provider foundations, cost governance |
| Deployment pipeline review | End-to-end delivery pipeline audit, release engineering patterns |
