monetizing-innovation
by wdavidturner
Use when asked about "pricing strategy", "willingness to pay", "value metric", "packaging tiers", "good better best pricing", "subscription vs usage pricing", or "price before product". Helps design products customers will pay for and choose pricing models that capture value. Based on Madhavan Ramanujam's Monetizing Innovation framework from Simon-Kucher.
trace-annotation-tool
by maragudk
Generate a custom trace annotation web app for open coding during LLM error analysis. Use when the user wants to review LLM traces, annotate failures with freeform comments, and do first-pass qualitative labeling (open coding). Also use when the user mentions "annotate traces", "trace review tool", "open coding tool", "label traces", "build an annotation interface", "review LLM outputs", or wants to manually inspect pipeline traces before building a failure taxonomy. This skill produces a tailored Python web application using FastHTML, TailwindCSS, and HTMX.
algorithms
by Tyler-R-Kendrick
Use when selecting algorithms, analyzing complexity, or reasoning about data structure choices. Covers Big-O notation, space vs time tradeoffs, amortized analysis, and algorithmic problem-solving strategy based on Knuth's "The Art of Computer Programming." USE FOR: algorithm selection, Big-O analysis, complexity comparison, choosing data structures, algorithmic problem-solving strategy DO NOT USE FOR: specific algorithm implementations (use sub-skills), system architecture (use dev/architecture), design patterns (use dev/design-patterns)
observability
by serkan-ozal
Monitor and debug web and Node.js applications using OpenTelemetry, console logs, network requests, and distributed tracing. Use when the user asks about distributed tracing, correlating frontend/backend requests, OpenTelemetry, Jaeger, or monitoring application behavior.
chaos-engineering-basics
by KentoShimizu
"Design and execute controlled chaos experiments to validate resilience assumptions with explicit steady-state metrics, blast-radius limits, and abort rules. Use when reliability claims need evidence before wider rollout; do not use for active incident command or postmortem-only reporting."
ab-testing
by KentoShimizu
"Controlled online experiment workflow for product changes with causal inference, randomization integrity checks, and pre-registered decision criteria. Trigger when ship/no-ship decisions require causal evidence under uncertainty and KPI trade-offs must be quantified. Do not use for feature-flag rollout policy without experiment design, deterministic functional verification, or observability-only analysis."
ceo-advisor
by ovachiever
Executive leadership guidance for strategic decision-making, organizational development, and stakeholder management. Includes strategy analyzer, financial scenario modeling, board governance frameworks, and investor relations playbooks. Use when planning strategy, preparing board presentations, managing investors, developing organizational culture, making executive decisions, or when user mentions CEO, strategic planning, board meetings, investor updates, organizational leadership, or executive strategy.
