tippyentertainment Skill

The ability to design and develop a Timesheet Application that enables users (individuals or teams) to track work hours, manage time entries, monitor productivity, and generate reports for billing, payroll, or analytics purposes. This skill combines frontend user experience, backend data management, and system integration expertise.

zsutxz Bundle

Implements any user intent, requirement, story, bug fix or change request by producing clean working code artifacts that follow the project's existing architecture, patterns and conventions. Use when the user wants to build, fix, tweak, refactor, add or modify any code, component or feature.

tippyentertainment Skill

Diagnose and fix Vite + React 19 configuration issues for TypeScript SPA and WASM preview builds. Specializes in React 19’s JSX runtime, @vitejs/plugin-react, path aliases, SPA routing, and dev-server behavior so the app and in-browser preview bundle cleanly without manual trial-and-error.

tippyentertainment Skill

Meticulously detect and fix missing React/TSX imports, undefined components, and bundler runtime errors in the WASM SPA build/preview pipeline. Ensures JSX components, icons, and hooks are properly imported or defined before running the browser preview, so the runtime safety-net rarely triggers.

thecraighewitt Bundle

Generate a polished, presentation-ready HTML slide deck from a topic, document, or set of notes. Use this whenever the user says 'make a slide deck,' 'build a presentation,' 'turn this into slides,' 'create a deck for,' 'pitch deck,' 'investor deck,' 'training deck,' or asks for slides on any topic. Outputs a single self-contained HTML file with scroll-snap navigation and a clean visual system. The deck should look like a designer made it, not a default template.

thecraighewitt Bundle

Process the user's email inbox: triage everything unread, classify by importance, draft replies for things that need one, and produce an HTML report of what was handled. Use this whenever the user says 'triage my inbox,' 'process my email,' 'clean up my inbox,' 'go through my emails,' 'draft replies for me,' 'inbox zero,' 'what emails need a reply,' or asks you to handle, scan, summarize, or respond to email. Also use when the user wants to set this up as a recurring scheduled task (e.g., 3x a day inbox sweeps). Requires Gmail connector.

jaykim88 Skill

Build forms with correct loading, success, and error UX using Server Actions + react-hook-form + Zod. Use when adding a new form, after QA reports form bugs, when errors aren't announced or input is lost on submit, or before shipping. Not for general state-store selection (use state-management-decisions) or non-form error/empty UI states (use async-ux-states).

jaykim88 Skill

Build a backend CI/CD pipeline — containerized builds, type-check/lint/test gates, DB migration as an explicit gate, SHA-tagged images, and blue-green/canary deploy with rollback. Use at project init, when deploys are manual/risky, or when migrations break production. Not for designing the migration itself (use migration-strategy) or the test pyramid (use test-strategy).

jaykim88 Skill

Backend testing pyramid — unit for pure logic, integration against a real DB (Testcontainers), and consumer-driven contract testing (Pact) for service boundaries. Use before a feature, after a bug fix, or when services break each other on deploy. Not for load testing (use performance-profiling) or security testing (use backend-security-audit).

thecraighewitt Bundle

Generate a daily briefing dashboard that pulls calendar, email, and news into one interactive HTML page. Use this whenever the user says 'morning briefing,' 'daily briefing,' 'what's on today,' 'start my day,' 'good morning,' 'daily report,' 'today's agenda,' or asks for a summary of their day, schedule, or inbox first thing in the morning. Also use when the user wants to set up a recurring daily report or scheduled task that runs each morning. Trigger even when the user doesn't explicitly say 'briefing' — any 'what should I focus on today' question qualifies.

jaykim88 Skill

Build LLM features on the backend — deterministic agent loops (round-trip every tool call by id), RAG over a vector store, token/cost accounting, streaming, eval harness, and prompt-injection defense (treat all model context as untrusted). Use when adding an AI feature, building RAG, or wiring an agent loop. Not for the AI streaming UI on the frontend (use frontend-toolkit's AI integration) or general boundary input parsing (use data-validation).

jaykim88 Skill

OWASP Top 10 audit for frontend — XSS via dangerouslySetInnerHTML, env-var leaks, token storage, CSRF, broken access control (IDOR), open redirect, CSP, Supabase RLS, CORS, Zod env validation. Use when adding auth, after handling external input, before shipping, or quarterly. Not for the initial env-validation setup (use developer-experience) or wiring npm audit / CSP regression tests into CI (use cicd-pipeline).

jaykim88 Skill

Design a cache layer — cache-aside read/write/invalidate, TTL + jitter, stampede prevention (single-flight / probabilistic refresh), and explicit invalidation. Use when read latency is high, the DB is read-bound, or a hot key causes thundering-herd load. Not for fixing the slow query at its source (use query-optimization first) or HTTP/browser caching (a frontend concern).

jaykim88 Skill

Ensure every async view handles loading, error, and empty states correctly with proper Suspense boundaries and custom 404/500 pages. Use when QA reports blank screens, infinite spinners, or undefined exposure, or before shipping. Not for choosing route render strategy (use render-strategy-decision) or form-specific error handling (use form-ux).

jaykim88 Skill

Refactor TypeScript/React code for readability and maintainability — remove `any`, name compound conditions, apply guard clauses, extract magic literals to constants, deduplicate shared logic. Use during PR review, before a feature touches a complex area, or on a weekly cadence. Not for component-level extraction (use component-quality) or cross-file/module restructuring (use architecture-improvement).

jaykim88 Skill

Write RFC and ADR documents to capture technical decisions (including rejected alternatives) — Context / Options / Decision / Consequences format. Use before a hard-to-reverse architecture decision, when designing a large feature, when technical choices spark debate, or when PR reviewers request rationale. Not for evaluating a library to adopt (use new-tech-evaluation) or prioritizing debt migrations (use tech-debt-management) — this records the resulting decision.

jaykim88 Skill

Audit and improve animations for 60fps, prefers-reduced-motion compliance, motion-feel (duration/easing), and accessibility. Use when jank appears in scroll/interaction, INP regresses, an animation auto-plays/loops or flashes, or before shipping. Not for diagnosing broad Core Web Vitals regressions (use rendering-performance) or full WCAG conformance auditing (use accessibility-audit).

thecraighewitt Bundle

Build an interactive HTML dashboard from any data source — a CSV file, a folder of files, a spreadsheet, or pasted numbers. The dashboard shows KPIs, charts, and lets the user filter and explore. Use this whenever the user says 'build a dashboard,' 'visualize this data,' 'turn this into a dashboard,' 'KPI dashboard,' 'metrics dashboard,' 'show me trends in,' or has data they want to see and explore visually rather than as a table. Works for business KPIs, financial data, project tracking, personal metrics, survey results, anything tabular.

thecraighewitt Bundle

Generate an interactive HTML diagram of the user's business systems, workflows, or tooling — showing how everything connects, where data flows, which AI agents / scheduled tasks run when, and how processes hang together. Use this whenever the user says 'visualize my workflow,' 'map my systems,' 'show me how this all connects,' 'business OS,' 'system diagram,' 'workflow map,' or wants to see the architecture of their work as a picture rather than a list. Output is a single self-contained HTML file with clickable nodes and progressive disclosure of detail.

thecraighewitt Bundle

Generate an animated, interactive HTML page that explains a complex concept through real-world analogies, visual diagrams, and progressive disclosure. Use this whenever the user says 'explainer infographic,' 'explain how X works,' 'make an explainer for,' 'visualize this concept,' 'turn this into a visual,' 'help me understand X visually,' or asks to break down a topic in a bite-sized visual format. Output is a single self-contained HTML file the user can open in a browser, scroll through, or share as a link. Topics can be anything — finance concepts, technical systems, scientific processes, business frameworks.

jaykim88 Skill

Improve React component design — split Container/Presentational, add useEffect cleanup, extract custom hooks, apply cva + cn() consistently, decide extraction with explicit criteria. Use when a pattern repeats 2+ times, a file exceeds 500 LOC, or PR review flags component complexity. Not for non-component code changes (use code-refactoring) or extraction into the shared component library (use design-system-construction).

jaykim88 Skill

Build mobile-first responsive layouts — breakpoint strategy, fluid type/space with clamp(), container queries, mobile viewport units (dvh) + overflow robustness, touch-target testing, responsive images. Use when adding a layout, when mobile bugs appear, or before shipping a public page. Not for codifying breakpoint/fluid scales as design tokens (use design-system-construction) or auditing touch-target size and zoom against WCAG (use accessibility-audit).

jaykim88 Skill

Instrument a backend with the three signals unified by one correlation context — structured logs, metrics (RED for services, USE for resources), and distributed tracing (OpenTelemetry + W3C Trace Context). Use before production, when debugging is blind, or when an incident has no trail. Not for diagnosing specific bottlenecks (use performance-profiling) or AI-specific token/cost metrics (use ai-llm-backend on top of this backbone).

jaykim88 Skill

Reduce initial JS bundle size via Bundle Analyzer, optimizePackageImports, code splitting, and unused-dep removal. Use when bundle exceeds target, after adding a large dependency, when Lighthouse Performance drops, or before shipping. Not for diagnosing runtime Core Web Vitals (use rendering-performance) or evaluating a library's size before adopting it (use new-tech-evaluation).

jaykim88 Skill

Evaluate a new library, framework version, or AI integration with bundle size, TypeScript support, maintenance status, security/supply-chain, and migration + exit cost. POC + benchmark before adoption. Use at quarterly tech review, when a new library could solve a pain point, on a React/Next.js major version release, or on AI API major updates. Not for recording the resulting decision (use decision-records) or shrinking an already-adopted dependency (use bundle-optimization).

jaykim88 Skill

Audit and optimize third-party scripts — analytics, tag managers, chat widgets, embeds — with the right loading strategy, performance budget, facades, and CSP/consent controls. Use when adding a script, when TBT/INP regress, when a GDPR/CCPA consent requirement arises, or before shipping. Not for first-party bundle size (use bundle-optimization) or broad Core Web Vitals diagnosis (use rendering-performance).

jaykim88 Skill

Set up DX baseline — ESLint + Prettier + husky + lint-staged + commitlint, strict TypeScript, path alias, t3-env for typed env vars, Node/package-manager pinning, .editorconfig, .vscode/extensions.json, CONTRIBUTING.md. Use at project start, during team onboarding, when ESLint warnings pile up, or local builds slow down. Coordinates with cicd-pipeline (local pre-commit gating complements CI) and security-audit (typed env validation hardens the secret-leak surface).

jaykim88 Skill

Inventory and prioritize technical debt — TODO/FIXME/HACK, any usage, deprecated APIs, untested logic — with impact × effort matrix. Use at quarter start, before a refactoring sprint, when a new teammate joins, or when feature velocity slows. Not for actually paying down debt (use code-refactoring) or recording a migration approach (use decision-records) — this only inventories and prioritizes.

jaykim88 Skill

Diagnose and fix Core Web Vitals (LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1) with measurement-first methodology. Use when Lighthouse drops, CWV field data fails, users report slowness, or before shipping. Not for when JS payload is the bottleneck (use bundle-optimization) or moving work to the server (use render-strategy-decision).

Patterns and utilities for building React components in house-maint-ai

caphtech Bundle

Use this skill for UI/UX, frontend visual design, product flow, landing page, dashboard, component, or design-system-aware work where design reasoning should be traceable, isolable, and retractable. It orchestrates context reading, relation mapping, hypothesis generation, artifact design, critique, and trace archival. This is about the reasoning process, not visual output methodology — for HIG/Material Design/Atomic Design-driven UI or design-system construction without a trace/retraction workflow, use design-plugin's web-app-designer, mobile-app-designer, or design-system-builder instead.
