Decide where files live in an ML experimentation project: reusable code in `src/<pkg>/`, one `# %%` script per experiment in `experiments/`, design notes + index in `journal/`, reports in `reports/`, agent-only probes in `scratch/`, narrative digest in `overview/summary.md`. Owns the layout, the file-creation rules (one file per experiment, ask before editing), and the jupytext `# %%` script convention. Never imposes `data/` — the user owns that. TRIGGER — any of: - Starting a new ML project / scaffolding a workspace. - About to create the first experiment file in a project. - About to create `src/<pkg>/data.py` / `features.py` / `pipeline.py` / `evaluate.py` for the first time. - About to write a `.ipynb` for experimentation — redirect to a `# %%` script under `experiments/`. - User asks where something should live, how to organize the project, or how to set up the workspace. - About to add a new experiment iteration — decide new file vs edit existing (ask the user). SKIP when: the file is clearly part of an already-populated module (e.g., adding a function to existing `features.py`); pure refactor inside a single existing file; pipeline declaration mechanics (`build-ml-pipeline`); evaluation mechanics (`evaluate-ml-pipeline`); skore symbol lookup (`python-api`). HOW TO USE: **first run the Detection table** below — if any signal matches, glue to existing conventions (do not rename or move folders). If no signal matches, scaffold the default layout. **Emit the Pre-flight checklist as visible text and read the Stop conditions before any file is created or edited.** Use templates in `templates/`; copy and adapt, do not rewrite from scratch.
Comprehensive backend development skill for building scalable backend systems using NodeJS, Express, Go, Python, Postgres, GraphQL, REST APIs. Includes API scaffolding, database optimization, security implementation, and performance tuning. Use when designing APIs, optimizing database queries, implementing business logic, handling authentication/authorization, or reviewing backend code.
Domain-Driven Design system for software development. Use when designing new systems with DDD principles, refactoring existing codebases toward DDD, generating code scaffolding (entities, aggregates, repositories, domain events), facilitating Event Storming sessions, creating bounded context maps, or performing code reviews with a DDD lens. Covers both strategic design (bounded contexts, subdomains, context maps, ubiquitous language) and tactical design (entities, value objects, aggregates, domain services, repositories). Supports all major architecture patterns (Hexagonal/Ports & Adapters, CQRS, Event Sourcing, Clean Architecture) with language-agnostic guidance and concrete examples in Python and TypeScript.
Build Next.js 16 + React 19 + TinaCMS sites with visual editing, blocks-based page builder, and complete SEO. Use this skill whenever the user mentions TinaCMS, Tina CMS, Next.js with a CMS, visual editing with Next.js, click-to-edit, content-managed Next.js site, blocks pattern page builder, or migrating to Next.js + TinaCMS. Also trigger for TinaCMS schema design, self-hosted TinaCMS, TinaCMS media configuration, or any TinaCMS troubleshooting. Covers Day 0-2 setup from scaffolding through production deployment on Vercel.
Interactive wizard for creating Claude Code skills. Use when scaffolding new skills, validating skill structure, managing dependencies, or editing skill configuration files.
Generate production-ready monorepo structures for full-stack applications including frontends (Next.js, React), APIs (Hono, Express), and data pipelines. Use when creating new monorepo projects, scaffolding multi-project architectures (web apps, APIs, workers, CLI tools), setting up shared packages, or configuring workspace tooling with Bun, PNPM, or Yarn.
This skill should be used when the user asks to "deploy to castari", "deploy my agent", "deploy agent to production", "castari deploy", "push agent to castari", "ship my agent", "set up castari", or needs help with Castari CLI installation, authentication, agent scaffolding, or deployment to cloud sandboxes.
Production-ready starter project for React + Cloudflare Workers + Hono with core services (D1, KV, R2, Workers AI) and optional advanced features (Clerk Auth, AI Chat, Queues, Vectorize). Complete with planning docs, session handoff protocol, and enable scripts for opt-in features. Use when: starting new full-stack project, creating Cloudflare app, scaffolding web app, AI-powered application, chat interface, RAG application, need complete starter, avoid setup time, production-ready template, full-stack boilerplate, React Cloudflare starter. Prevents: service configuration errors, binding setup mistakes, frontend-backend connection issues, CORS errors, auth integration problems, AI SDK setup confusion, missing planning docs, incomplete project structure, hours of initial setup. Keywords: cloudflare scaffold, full-stack starter, react cloudflare, hono template, production boilerplate, AI SDK integration, workers AI, complete starter project, D1 KV R2 setup, web app template, chat application scaffold, RAG starter, planning docs included, session handoff, tailwind v4 shadcn, typescript starter, vite cloudflare plugin, all services configured
Use when scaffolding a new Nuxt 4 project with standard config files (prettier, eslint, gitignore, husky, vitest, tsconfig, sops) and bun scripts.
Guides the agent through creating a new Ionic app using the Ionic CLI. Covers project scaffolding with ionic start, framework selection (Angular, React, Vue), template selection (blank, tabs, sidemenu), Capacitor integration, and optional Tailwind CSS setup. After app creation with Capacitor integration, delegates to the capacitor-app-creation skill for further Capacitor setup. Do not use for existing Ionic projects, migrating Ionic apps, upgrading Capacitor versions, or non-Ionic mobile frameworks.
Project scaffolding templates for new applications. Use when creating new projects from scratch. Contains 12 templates for various tech stacks.
Add gateable features to an existing browser game — skin picker, continue-after-death, bonus mode, save slots, daily challenge. Monetization-agnostic scaffolding that leaves clean hooks for any paywall, subscription, or entitlement layer. Features are scaffolded at silver and gold tiers only (bronze is the default everyone gets). Use when the user says "add gateables", "scaffold monetizable features", "add skin picker", "add continue-after-death", "make my game monetizable", or "add premium hooks". Do NOT use for Play.fun SDK integration (use monetize-game) or generic gameplay features (use add-feature).
