Production-ready authentication framework for TypeScript with first-class Cloudflare D1 support. Use this skill when building auth systems as a self-hosted alternative to Clerk or Auth.js, particularly for Cloudflare Workers projects.

Pre-ticket Fibonacci sizing for a paste-mode batch of user stories. Default mode is advisory-only (writes a Story Sizing Report). Opt-in `--auto-create` delegates ticket creation to mk:jira-issue + mk:jira-collaborate with mandatory dry-run + single batch confirmation gate. NOT for single-ticket estimation (mk:jira-estimator); NOT for sprint capacity (mk:planning-engine).

Review a technical specification through expert lenses. Use to identify gaps, risks, and missing considerations in an existing spec. Works on any tech spec, not just those created with tech-spec:create.

GitOps workflows and patterns using ArgoCD and Flux for declarative Kubernetes deployments. Use when implementing CI/CD for Kubernetes, managing multi-environment deployments, or adopting declarative infrastructure practices.

Enforces KISS/DRY/YAGNI during authoring and ad-hoc quality reviews. Pragmatic standards: concise, direct, no unnecessary comments. NOT for post-hoc diff/PR review (see mk:review); NOT for behavior-preserving simplification passes (see mk:simplify).

Aplica os princípios SOLID para desenvolvimento em Ruby 3.3+ e Rails 8, com foco em arquitetura modular, módulos obrigatórios, arquivos com menos de 100 linhas e contratos separados.

Use MeMesh to remember, recall, and manage AI knowledge across sessions. Triggers when the user asks to remember something, recall past decisions, forget outdated info, learn from mistakes, or analyze work patterns. Also triggers proactively when you make important decisions, fix bugs, or learn lessons worth preserving.

Use when starting any conversation - establishes mandatory workflows for finding and using skills, including using Skill tool before announcing usage, following brainstorming before coding, and creating TodoWrite todos for checklists

Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses

Periodic journal review — scans daily entries to surface unlogged decisions, unlogged learnings, untracked action items, and recurring themes. Use when the user says "journal audit", "review my entries for promotion", "extract decisions", "unlogged items", "what should I formalize", "untracked items", or wants to promote daily notes into formal entries. NOT for weekly summaries — use /journal-reca

Use quando o usuário solicitar a análise de issues/PRs de um repositório GitHub para identificar oportunidades de demanda comercial de alto valor. Gera cartões de demanda pontuados com análise JTBD, pontuação RICE, evidências de soluções alternativas e rascunhos de sondas fake-door, além de identificar lacunas de mercado em PRs rejeitados/estagnados.
