What’s New in v0.16.0

askable-ui v0.16.0 makes Qwik integrations genuinely resumable, expands the MCP package into a command-line server with live resources, and publishes the Context Packet Protocol as a first-class specification. It also includes a broad reliability and security pass across the framework adapters, MCP bridge, and browser sources.

Highlights

Resumable Qwik actions

Imperative actions returned by @askable-ui/qwik hooks are now Qwik QRL values. They can be invoked safely from optimizer-generated event handlers and after browser resume without capturing non-serializable closures.

import { $, component$, sync$ } from '@builder.io/qwik';
import { useAskableStream, useAskableTableSource } from '@askable-ui/qwik';

export default component$(() => {
  const stream = useAskableStream({
    sanitizeText: sync$((text) => text.trim()),
  });
  const table = useAskableTableSource({
    rows: $(() => [{ id: 'order-1', total: 42 }]),
  });

  return (
    <button onClick$={async () => {
      await table.notifyChanged();
      await stream.stream(
        'Summarize the visible orders',
        $(async (_request, emit, signal) => {
          if (!signal.aborted) emit('Ready');
        }),
      );
    }}>
      Ask
    </button>
  );
});

Qwik callback options use $() for asynchronous callbacks and sync$() for synchronous callbacks. Mutation actions are asynchronous because a resumed QRL may need to load its implementation chunk. The package now requires Qwik 1.6 or newer so its public declarations can use SyncQRL.

The Qwik lifecycle also now:

• creates browser-owned contexts only from visible tasks;
• keeps runtime objects behind NoSerialize references;
• suppresses stale stream/chat results when a newer request takes ownership;
• aborts active handlers during cleanup;
• prevents late asynchronous source factories from registering after release;
• unregisters source handles exactly once.

See the Qwik guide for the complete callback and lifecycle model.

MCP command-line server and live resources

@askable-ui/mcp now ships a stdio CLI for command-based MCP clients. Point it at an HTTP endpoint or a Context packet file:

npx @askable-ui/mcp --url http://localhost:3000/api/context
npx @askable-ui/mcp --file ./context-packet.json --require-redacted

The MCP server adds a live askable://current resource and a list_context_sources tool, while preserving prompt-ready formatting and redaction enforcement. The package also ships a schema-validated MCP Registry manifest for registry submission and downstream distribution.

Context Packet Protocol and source guides

The documentation now treats Context packets as a versioned, framework-neutral protocol rather than only a library implementation detail. New guides cover:

• the Context Packet Protocol specification;
• custom context sources;
• cart and multistep sources;
• React Native integration;
• browser-local and remote MCP integration.

The React, Vue, Svelte, SolidJS, and Qwik packages also re-export a11yTextExtractor so accessible text extraction is discoverable without a separate core import.

Reliability and security

This release includes fixes for:

• stale React navigation callbacks after option changes;
• adapter context option leakage between independently configured hooks;
• Qwik context access before the browser-visible lifecycle;
• byte-based MCP request limits for multibyte payloads;
• unsafe storage masking defaults and page-bridge target-origin handling;
• production dependency vulnerabilities;
• verified issues across create-app, Svelte, React, Vue, MCP, and Context packet handling.

Upgrade

Keep all Askable packages on the same release line:

npm install @askable-ui/core@^0.16.0 @askable-ui/react@^0.16.0

For Qwik applications:

npm install @askable-ui/qwik@^0.16.0 @builder.io/qwik@^1.6.0

Update Qwik callback options to $() or sync$() and await imperative hook actions where ordering matters. No migration is required for the other framework packages beyond updating their aligned package versions.
