skillsctl-usage@0.2.0 in registry is stale; upstream already has the fix

[dcmcand]

The skillsctl-usage skill served by the registry is at v0.2.0 and documents --file for skillsctl publish. The actual CLI flag is --dir, so running the published instructions verbatim fails with unknown flag: --file.

Upstream skills/skillsctl-usage.md already has the fix (plus docs for --project and multi-file skills) as of commit 5df43bc (2026-04-15). The registry has not been re-seeded since, so skillsctl install skillsctl-usage still pulls the old content.

Ask

Redeploy the backend (or otherwise bump the seeded version) so skillsctl install skillsctl-usage returns the current file.

Reproduce

$ skillsctl explore show skillsctl-usage
Name: skillsctl-usage
Version: 0.2.0   # content still uses --file

$ skillsctl publish --name foo --version 1.0.0 --description x --file ./foo.md
Error: unknown flag: --file
