What's new in each skill

emulate 0.5.0

Clerk emulator added (auth + sessions) → 13 total
portless integration: emulators run embedded under portless URLs (no dedicated port needed)
Stripe Checkout example + Resend magic-link example shipped
Google OAuth hd claim support
AWS S3 emulator now matches the official SDK wire format (was a compat bug)

portless 0.12.0 (via 0.11)

--tailscale shares apps over your tailnet with auto-HTTPS on 443
--funnel exposes apps publicly via Tailscale Funnel
Bare portless auto-discovers package.json dev scripts; multi-app monorepos get auto subdomains; Turborepo task-graph aware
portless.json config file supported; --script overrides default "dev"
portless prune removes orphaned dev servers + stale Tailscale registrations
State dir moved to ~/.portless (was scattered)
Rsbuild + VitePlus auto-port injection (on top of existing Vite/Next)

agent-browser 0.26.0

agent-browser doctor — one-shot diagnostic. Flags: --offline, --quick, --fix, --json. Run before opening an issue
Stable string tab IDs (t1, t2, ...) with optional --label for memorable names. Survives daemon restart
core skill expanded with comprehensive snapshot-ref-act loop guide
Config $schema reference for IDE auto-completion (https://agent-browser.dev/schema.json)
Fixed: --state not loading saved cookies/localStorage at launch

@json-render/core 0.18.0

5 new devtools packages: @json-render/devtools + adapters for React, Vue, Svelte, Solid
Inspector panel: 6 tabs (Spec, State, Actions, Stream, Catalog, Pick) with DOM element-picking → spec key
Devtools tree-shake to null in production builds
Action observer + devtools flag exposed for adapter integration
Companion Next.js demo app with AI-chat + catalog integration
Zod 4 fix: formatZodType handles z.record(), z.default(), z.literal() correctly (was empty/wrong)

Sibling: wterm research issue

User asked about wterm too. Vercel Labs released vercel-labs/wterm at @wterm/{dom,react,core}@0.2.1 — terminal emulator for the web (Zig + WASM, ~12KB). Not currently used in OrchestKit. Issue #1557 opened to decide: defer / track-only (add to version watcher) / build a terminal-emulator skill.
