Also, wouldn't it be better if the encryption and fragmented compression could also be handled on the web client side?

One thing that bothered me is that Skills usually sit outside normal package-manager protections.
Package ecosystems are increasingly using ideas like pnpm’s `minimumReleaseAge` and uv’s `--exclude-newer` to avoid pulling in artifacts that are too new. But Skills often aren’t package-managed at all, even though they may include helper scripts, downloaded artifacts, and even binaries.
Given recent supply-chain incidents like the axios compromise, and research like Snyk’s ToxicSkills report, that felt like a real gap.
So I added a cooldown mechanism based on the Git tree hash of the skill directory.
The CLI now resolves a Skill from Git history, treats the skill directory tree as the release unit, and only installs/updates to a tree that is older than a configured minimum age. If the latest one is too new, it falls back to the newest eligible older tree.
This is implemented as `--min-age` for add/download/update. ex. `sk add https://github.com/remotion-dev/skills --min-age 30`
I’d be especially interested in feedback on whether “directory tree hash” seems like the right trust/version boundary for non-package-managed AI artifacts.
Packaging skills with libraries/CLIs and letting agents discover them from installed packages makes a lot of sense. I see Harbor as addressing a different layer on top of that: organizational collection, cataloging, provenance, governance, and safety.
Yes, I agree that MCP-based prompt/skill delivery would be a very interesting direction.
If tooling vendors broadly supported MCP prompts, an MCP server could become a dynamic distribution layer for team-managed skills, which would remove a lot of sync-oriented workflow.
My current assumption is that we still need something Git-native today because:
- skills are mostly authored and reviewed in Git
- teams need provenance and governance around them
- tool support for MCP prompt delivery is still incomplete
So I see Harbor more as a practical system for the current ecosystem, not necessarily the final shape.
