Chain Hub Pro

Chain Hub Pro is an optional add-on on top of the open-source hub. Your library still lives in one place — ~/chain-hub — with no second copy of skills on disk. Pro unlocks Brain (Memory + Pipeline), adds a private skill pack (design, shipping, and stack workflows), and extends Design System with Pro presets and generators.

See the Pro overview for pricing and early-access requests. This page covers activation, pack inventory, and what changes in the local dashboard. For magic-link sign-in and device management, see Account.

Three steps after purchase or approval

A license key alone does not install skills. Follow all three steps:

1. Get your key — Checkout, beta approval, or Account after sign-in. Copy the CHAIN-… key from the dashboard or welcome email.
2. Activate — Registers the license locally and unlocks Brain in the hub.
3. Install pack — Downloads Pro skills, agents, workflows, and rules into ~/chain-hub while the license is active.

In chain hub: paste the key under Settings → Pro, confirm status, then use Install Chain Hub Pro pack on the Dashboard.

What Pro adds in the hub

The sidebar groups Pro routes under a Pro label (after Workflows):

Design System is not fully gated: you can build and export design tokens without Pro. Pro-only actions show an inline upsell when inactive.

Brain requires an active license. The open-source hub still includes chain capture and local learnings files; distillation and the approval UI live behind Pro.

Pro pack inventory

After chain pro install-pack, the pack delivers 44 skills, 15 agents, 19 workflows, and 1 team rule (pack 0.16.1) — structured playbooks with reference files and smoke prompts, from design direction through modern stack build to ship gates.

Full inventory for pack 0.16.1 (44 skills, 15 agents, 19 workflows, 1 team rule). Newer releases may add or rename slugs — run chain pro refresh-pack and chain list after upgrade.

Refresh and delivery

• Refresh pack: chain pro refresh-pack or chain update when the pack is registered in skills-registry.yaml
• HTTPS delivery (default): manifest + tarball from the configured release host (for example packages.chainhub.one/pro-pack/) — no GitHub collaborator invite
• Override manifest URL: chain config set pro_pack_manifest_url <url>
• Legacy GitHub delivery: private chain-hub-pro repo + chain add github:<org>/chain-hub-pro --pack (requires gh auth login or GITHUB_TOKEN)
