log-entity-actions-pattern
by igbuend
Security pattern for implementing security logging and audit trails. Use when designing logging systems for security events, implementing non-repudiation, creating audit trails, or addressing security monitoring and incident response needs. Addresses "Entity repudiates action request" problem.
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.
ab-test-setup
by ngxtm
"Structured guide for setting up A/B tests with mandatory gates for hypothesis, metrics, and execution readiness."
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."
wide-events
by front-depiction
Conceptual guide to wide events (canonical log lines) for observability. Use when thinking about instrumentation strategy, span annotations, or designing what context to capture.
hierarchy-of-marketplaces
by wdavidturner
Use when asked about "marketplace strategy", "chicken and egg problem", "liquidity", "two-sided market", "tipping a marketplace", "GMV growth", or "Sarah Tavel marketplaces". Helps founders and product leaders build defensible marketplace businesses by sequencing supply and demand. The Hierarchy of Marketplaces framework (created by Sarah Tavel / Benchmark) provides a progression from focused launch to market dominance.
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.
trustworthy-experiments
by wdavidturner
Use when asked to "run an A/B test", "design an experiment", "check statistical significance", "trust our results", "avoid false positives", or "experiment guardrails". Helps design, run, and interpret controlled experiments correctly. Based on Ronny Kohavi's framework from "Trustworthy Online Controlled Experiments".
hierarchy-of-engagement
by wdavidturner
Use when asked to "define our core action", "North Star metric", "accruing benefits", "improve retention mechanics", "hierarchy of engagement", or "Sarah Tavel framework". Helps consumer products identify the actions and benefits that drive long-term retention. The Hierarchy of Engagement framework (created by Sarah Tavel at Benchmark) maps progression from core action to mounting loss.
checkpoint-workflow-builder
by jackspace
Build resumable state-machine workflows with checkpoint patterns, progress preservation, and automatic recovery for complex multi-phase operations that need to survive interruptions, timeouts, and failures.
log-work
by MichaelVessia
Log work activity to today's journal
autoresearch
by chrisliu298
Autonomous experiment loop faithful to Karpathy's autoresearch. Set up a branch, establish a baseline, then loop forever: edit, commit, run, measure, keep or revert. Use when asked to "run autoresearch", "optimize X in a loop", or "start experiments".
secret-scanning-investigator
by swannysec
Investigate GitHub secret scanning alerts to trace provenance, gather context, assess risk, and produce a structured report for security professionals. Handles one or more alerts in a single investigation using only open-source tools.
my-logs
by ex3ndr
Explain how to do logging
web-perf
by nicholasgriffintn
Audits web performance using Chrome DevTools MCP. Measures Core Web Vitals, finds render-blocking resources, dependency chains, layout shifts, caching issues, and accessibility gaps. Use for audits, profiling, debugging, or optimising page load performance and Lighthouse scores.
update-study
by iamseungpil
This skill should be used when the user asks to "update study", "analyze new experiments", "update experiment document", or "refresh study notes". Produces academic-paper-quality experiment reports with matplotlib plots, executive summary with comparison tables, implementation structure, experimental results with figure interpretation, proposed improvements with code examples, hypotheses, limitations, and LaTeX PDF export with figures. Features incremental detection (only analyze NEW experiments), data extraction to DataFrame, automated plot generation, iterative writing improvement loop with quality criteria, zero-hallucination verification, and LaTeX PDF export. Usage - /update-study logs/experiment.log study.md or /update-study "logs/exp1.log logs/exp2.log" results/ablation_study.md
decision-log
by mkdir700
"MANDATORY pre-commit workflow for vibe coding. ALWAYS trigger when user says 'commit', 'git commit', or any commit-related command. Forces diff review and decision log generation BEFORE allowing commit to proceed."
work-management
by ajshedivy
"Query, monitor, and analyze jobs on IBM i using SQL table functions via ibmi-mcp-server. Use when user asks about: (1) finding jobs by status, user, subsystem, or type, (2) monitoring active job performance (CPU, I/O, memory), (3) detecting long-running SQL statements, (4) analyzing lock contention, (5) checking job queues, (6) replacing WRKACTJOB, WRKUSRJOB, WRKSBSJOB, WRKSBMJOB commands, or (7) any IBM i work management task."
observability-specialist
by k1lgor
Use this for setting up monitoring, logging, distributed tracing, and alerting for applications and infrastructure.
regex-pattern-builder
by Dexploarer
Builds and explains regex patterns from natural language, tests patterns, and provides examples. Use when user asks to "create regex", "regex pattern", "match pattern", "validate email/phone", or "regex help".
kubernetes-orchestration
by spjoshis
Master Kubernetes with pods, deployments, services, ingress, ConfigMaps, secrets, and production cluster management.
iterative-code-evolution
by aaronjmars
Systematically improve code through structured analysis-mutation-evaluation loops. Adapted from ALMA (Automated meta-Learning of Memory designs for Agentic systems). Use when iterating on code quality, optimizing implementations, debugging persistent issues, or evolving a design through multiple improvement cycles. Replaces ad-hoc "try and fix" with disciplined reflection, variant tracking, and principled selection of what to change next.
