TypeScript is the most common stack in the catalogue. These loadouts teach your agent strict typing and the conventions of the platform underneath, whether that is a Cloudflare Worker with D1 bindings, an Electron or Tauri desktop app, an Expo app, a Phaser 4 game, a Discord bot, an MCP server of your own or a Playwright suite. Most include an example the verifier type-checks or runs.
Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
discord.js v14 rules and an add-a-slash-command skill for building a Discord bot that registers commands properly and never leaks its token.
Rules and an add-a-tool skill for building a Model Context Protocol server in TypeScript that agents can actually use well — clear tools, safe inputs, no stdout noise.
Rules, an RLS audit skill and a read-only Supabase MCP config for vibe-coding a Next.js App Router SaaS without leaking your database.
A launch-check skill and always-on security rules that catch leaked keys, open databases and missing auth before your vibe-coded app goes live.
Astro conventions for fast, zero-JS-by-default sites with content collections, plus a skill for deploying to Cloudflare Pages with headers and redirects.
Manifest V3 rules for service workers, messaging and minimal permissions, plus a skill that gets your extension through Chrome Web Store review.
Workers rules for agents: bindings from env, wrangler types, prepared D1 queries, waitUntil, secrets via wrangler secret, no deploys or --remote writes unasked.
Electron rules for agents: sandboxed renderers, narrow contextBridge APIs, sender-checked IPC, deny-by-default windows, CSP and fuses, with a static security check.
Expo rules for agents plus Expo's official MCP server: npx expo install, Expo Router, no secrets in EXPO_PUBLIC_, no production EAS releases, check on a simulator.
Checks whether an Expo change can ship as an EAS Update or needs a new build, using the native fingerprint; preview by CI, production rollouts by a person.
Move an MCP server to the stateless 2026-07-28 revision on the official SDKs: no sessions or handshake, server/discover, input_required, then a raw stdio probe.
Phaser 4 rules that send the agent to the skills Phaser ships in node_modules, not v3 tutorials: pooled objects, delta movement, play-tested changes.
Rules for agents writing and healing Playwright tests, including Playwright's test agents: role locators, web-first assertions, no sleeps, never weaken a test to pass.
Tauri 2 rules and a permissions skill: capabilities for named windows, scoped fs and http, no shell execute, a CSP kept, plus a checker that flags wide grants.
