Hi @jwei-ant — gentle nudge on this one. @yamz8's force-push on 2026-01-15 resolved the signing blocker (current head c018844 shows verification.verified: true, reason: valid), but the PR has been sitting in BLOCKED state since, likely because the earlier approval was invalidated by the force-push and it needs a fresh review pass.

Context for why this is worth unblocking: the skill is referenced in the official tutorial at https://claude.com/resources/tutorials/how-to-use-the-scientific-problem-selection-skill-with-claude, so anyone following the docs currently hits not found in marketplace when they run the exact command the tutorial tells them to run.

As backup, I've mirrored the same fix on my fork with a signed commit crediting @yamz8 via Co-authored-by (sanxiong-liu/life-sciences@3208ba9). Happy to open a superseding PR if that's easier than re-reviewing #30, but #30 is the original fix and the preferred merge path.

Thanks!
