Angular playbook for internal enterprise and forms-heavy admin apps — standalone components, typed reactive forms, signals, DI services, routing, and testing. Use when the app class is internal enterprise/admin.
Astro playbook for content/marketing/mostly-static sites — islands architecture, content collections, zero-JS by default, and selective hydration. Use when the app class is content/marketing.

Deploy an app to Railway — build/start command detection, service config, environment variables, private networking, databases, and health checks. Use when deploying any web app or service to Railway.
React Router v7 framework mode (Remix) playbook for chat/realtime/collaborative apps — loaders/actions, nested routes, streaming, optimistic UI, and why not Next. Use when the app class is chat/realtime.
SvelteKit playbook — routing, load functions, form actions, runes-based state, adapters, and testing. A defensible deviation when bundle size and authoring ergonomics are the priority. Use when the team picks Svelte.
On-demand install of long-tail stacks in a fresh environment — Angular CLI, Rust, uv/Python, Bun, Go, SvelteKit, via apt and mise. Use when the doctrine stack is not preinstalled on the box.
The all-encompassing default for the Paxeer/Matrix runtime. One skill that builds software (files + shell + supervised services + git), runs research (web search + fetch + full Playwright browser), and operates the Paxeer network end-to-end (reads across RPC/explorer/portfolio/price/precompiles, and wallet-gated writes: transfers, DEX swaps, perps, token launches, payment streams, staking, scheduled txs). Verbs build/modify/deliver are lifecycle stages, not domains. Every outcome is grounded in a real tool result — file bytes, exit code, service log, commit hash, fetched content, a quote, or a tx hash — never asserted from memory. Destructive, irreversible, or value-moving actions stop to confirm when unbounded, unauthorized, or unclear.
