🦖Curated Cursor AI agent skills, slash commands, MCP configs, subagents & rules for full-stack dev — React 19, Next.js 16, Supabase, Tailwind v4, TypeScript
Skill Claude CodeCodex
Wire ETL, ingestion, cron, edge-function, and queue jobs correctly. Use for "build a pipeline", "sync X into Y", "nightly aggregation", "cron double-counts", "dedupe", "backfill", "the numbers are wrong after a retry". Bakes in idempotency, atomic writes, data contracts, dead-letter, and observability.
Skill Claude CodeCodex
Build interactive, accessible charts, graphs, and data dashboards using Recharts, D3, or Victory. Use when the user says "chart", "graph", "data visualization", "analytics dashboard", "metrics display", "D3", "Recharts", "time-series", or "data display".
Skill Claude CodeCodex
Diagnose one error/bug with hypotheses and runtime evidence before fixing. Use when "debug this error", "investigate this bug", or behavior is unexpected. FE↔BE contract mismatch → debug-fe-be-integration. Sentry backlog/monitoring → debug-sentry-monitor. Bug-to-PR lifecycle → workflow-fix-and-ship.
Skill Claude CodeCodex
Diagnose and fix frontend↔backend contract failures by tracing client requests, server logs, validation, auth, and responses on both sides. Use for API 4xx/5xx, mismatched payloads, validation failures, or "frontend and backend disagree". Single-layer errors → debug-error.
Skill Claude CodeCodex
Operate Sentry: triage/fix unresolved issues, reduce noise, audit instrumentation, and monitor after deploy. Use when "check Sentry", "fix Sentry issues", "review production errors", or "improve error tracking". One named bug through PR → workflow-fix-and-ship. Plan-only observability → plan-error-handling.
Skill Claude CodeCodex
Release an npm package: version, CHANGELOG, publish, verify. Use when "publish this package", "release to npm", or "ship a new npm version". Running-app production deploy → workflow-ship-and-observe.
Skill Claude CodeCodex
Post-deploy smoke test across browser, Sentry, Supabase, Langfuse, and the public web. Use when "verify deploy", "smoke test production", "post-release check", or "ship or rollback". Deploy + observation loop → workflow-ship-and-observe. npm package release → deploy-npm.
Skill Claude CodeCodex
Design RESTful and GraphQL APIs following current best practices for naming, versioning, error shapes, and auth patterns. Use when the user says "design an API", "create endpoints", "structure my API responses", "plan API architecture", "REST vs GraphQL", or "API contract".
Skill Claude CodeCodex
Create museum-quality visual art in .png and .pdf formats using design philosophy. Use when user asks for poster, visual design, infographic, certificate, badge, banner, social media graphic, print design, or mentions "create artwork", "design graphic", "visual identity", or "print material".

Design and implement transactional and marketing email templates. Use when asked to "build an email template", "transactional email", "welcome email", "password reset email", "email design", "React Email", "MJML", "dark mode email", or "email copy review". Inbox / SPF / spam → enhance-email-deliverability.
Skill Claude CodeCodex
Create a new production-grade UI from scratch — not a polish pass. Use when "build this UI", "design this page", or "new dashboard layout". Polish existing → enhance-web-ui. Landing → enhance-web-landing. Redesign existing → enhance-web-redesign.
Skill Claude CodeCodex
Create original algorithmic visuals with p5.js, Canvas, or SVG using seeded randomness and interactive controls. Use when "generative art", "procedural visuals", "flow fields", "particle system", or "art from code". Data charts → data-visualization. UI illustration → design-frontend.
Skill Claude CodeCodex
Design mobile-first UIs: touch targets, safe areas, gestures, then enhance up. Use when building for small screens, touch, swipe, PWA, or tablet. Linearized desktop / responsive audit → audit-responsive.
Skill Claude CodeCodex
Design and implement new isolated motion — micro-interactions, page transitions, scroll, hover — with Framer Motion, CSS, or GSAP. Use when adding one animation to a new surface. Existing-app coherent pass → enhance-motion. Do not fire for "motion pass across the app".
Skill Claude CodeCodex
Generate Product Requirements Documents through structured conversation for any project. Use when starting a new feature, documenting requirements, creating specs before implementation, or needing clarity on scope and success criteria.
Skill Claude CodeCodex
Build a new design system (tokens, variants, theming). Use when "create a design system" or "component library from scratch". Drifted existing system → housekeep-design. Plan-only unification → plan-uiux-unification.
Skill Claude CodeCodex
Apply cohesive visual themes to artifacts (slides, docs, landing pages). Provides 11 pre-set themes with colors/fonts. Use when user mentions "apply theme", "color palette", "brand colors", "styling slides", "presentation design", "visual identity", or wants consistent styling across artifacts.
Skill Claude CodeCodex
Create and maintain lightweight Architecture Decision Records as agent-readable decision memory — what was decided, why, and which alternatives were rejected. Use when "record this decision", "set up ADRs", "the agent keeps suggesting Y again". Docs vs code drift → plan-docs-sync. Session state → handoff.
Skill Claude CodeCodex
Co-author structured documents (specs, PRDs, RFCs) through a 3-stage workflow: context gathering, drafting, and reader testing. Use when writing proposals, technical specs, or similar structured content. Repo decision-memory system (INDEX.md, rejected alternatives, agent rules) → docs-adr.
Skill Claude CodeCodex
Build and sharpen a project's domain model — a CONTEXT.md glossary and ubiquitous language. Use when pinning down terminology, or the agent "uses the wrong words". Repo decision-memory system (INDEX.md, rejected alternatives) → docs-adr.
Skill Claude CodeCodex needs its repo
Write developer docs: README content, API references, code comments, changelog entries. Use when "write docs", "document this API", "add code comments", or "explain for contributors". Visual README makeover → enhance-readme. Docs/code drift plan → plan-docs-sync. Collaborative long-form → docs-coauthor.
Skill Claude CodeCodex
Install guardrails-as-code so AI sessions cannot reintroduce leaked secrets, injection, or untested code. Use when "set up guardrails", "stop vibe-coding regressions", "add pre-commit security checks". Gate-logic audit → audit-gate-logic. Gate sprawl → housekeep-gates.
Skill Claude CodeCodex
Install mechanically-enforced architecture boundaries (dependency-cruiser / eslint-boundaries) so layer direction, feature isolation, and forbidden imports fail CI. Use when "enforce module boundaries" or "stop spaghetti imports". Advisory audit → audit-backend-architecture. Rule content → audit-doctrine.
Skill Claude Code
Cross-surface UIUX separation skill for hybrid web apps that ship as PWA + iOS + Android via Capacitor (or Tauri / Expo Web / Ionic / RN-Web). Use when a previous UI/UX sweep "improved one surface and broke the other" — desktop polished but mobile cramped, or mobile native but desktop wastes space.
