Carina Hub

The Carina Hub at hub.carinaai.uk is the public registry for domain packs: optional skill and knowledge bundles that extend the free Carina kernel.

Think of it like a package index for the agent kernel. The current public package (carina-agent) ships without domain packs; you choose what to install.

Hub vs kernel vs packs​

LayerWhat it isCost
Carina kernelTools, memory, routing, channels, CLI (carina-agent)Free, MIT
Domain packsOptional bundles (skills + knowledge + prompts)Free or premium on Hub
Labyrinth ScoutCommercial security product (separate brand)Paid plans

Installing the kernel does not enable any domain pack. Packs are opt-in via Hub install, web UI, or ACTIVE_SKILL_PACKS in config.

Browse and install​

Web​

  1. Open hub.carinaai.uk
  2. Search or browse packs
  3. Open a pack for version, author, skill count, and verified badge (official VERLOX packs)
  4. Run the install command shown on the pack page

CLI​

Install the kernel first:

npm install -g carina-agent
carina setup

Then install a pack:

carina pack search property
carina pack install property-uk
carina pack list

Set HUB_URL or SKILLS_HUB_URL if you use a local hub during development (pnpm hub in the monorepo).

Verified badge​

Official VERLOX-maintained packs (for example property-uk, core-engineering) show a verified badge on the Hub. Community submissions are welcome; verification is manual in v1.

Publish a pack (authors)​

Free to publish. You need a Hub publish token (CARINA_HUB_TOKEN or SKILLS_HUB_PUBLISH_KEY).

carina pack publish ./my-healthcare-pack

Requirements:

  • Valid pack.json (see Creating packs)
  • At least one .md knowledge file
  • No .env or secrets in the pack directory

Developer reference: Stable public API.

Hub v1 supports free and premium packs. Premium packs use Stripe Checkout on the Hub; free packs install with carina pack install only.

Developer guide: Selling a pack.

Hub vs in-app pack UI​

SurfaceWhereUse case
Hubhub.carinaai.ukPublic discovery, CLI tarball downloads, author publish
Web /packsYour Carina instanceEnable/disable packs already installed on that host
Ops panelops.carinaai.uk (VERLOX internal)Operator pack audit, not public

Self-hosting the Hub​

Production Docker stack: docker-compose.prod.yml includes a carina-hub service on port 3001, proxied by nginx at hub.carinaai.uk.

Local dev:

cd core.carinaai.uk
pnpm hub
curl -s http://localhost:3001/api/packs | jq .

DNS checklist for production:

  1. hub.carinaai.uk A/AAAA record to your VPS
  2. TLS certificate (certbot or existing carinaai.uk SAN)
  3. skills.carinaai.uk redirects to hub.carinaai.uk for backward compatibility
