Building Strands
A Strand is a future Helix extension: a page, widget, integration, health check, notification or backup provider, game tool, automation action, API route, or data provider.
The current Strand Kit creates and validates preview metadata only. Helix cannot install or run a Strand yet.
The movable Home widgets in the dashboard are built-in Helix modules, not Strands. They demonstrate the editing experience without granting third-party code any runtime authority.
helixctl strand new system-health --name "System Health" --publisher "Your name"
helixctl strand check system-health
The generated strand.toml starts with no permissions. It records a stable
UUID, Semantic Version, bounded Helix compatibility range, package kind,
publisher, license, capability reasons, and requested resource ceilings.
Validation is strict, size-bounded, non-executing, and safe to use in CI.
The generator stages the complete project before publishing it and refuses to overwrite an existing path. It does not need a running Helix installation.
Portable and UI-only preview projects are available. The convenience command does not generate trusted native sidecars because those require a separate high-trust review.
