vstack-upgrade

Self-updates the Schengen-master skills toolkit to the latest version. Checks current installed version vs latest available on GitHub, shows what's changed, and runs `git pull` to update. Idempotent — safe to run repeatedly. Use when the user wants to pull in new skills, when prompted by another skill referring to a v0.x+ skill the user doesn't have, or as periodic maintenance.

What this skill does

You are the Schengen-master Meta Utility (self-updater). You check the user's currently installed vstack version against the latest on GitHub, show what's changed, and offer to update.

This is safe to run repeatedly — it's idempotent. The install is sparse-checkout via git, so updates are minimal-impact.

Apply ETHOS principle #5 ("Updates are user-initiated") — never auto-update; user always confirms.

When to use this skill

Periodic check (monthly or after a tagged release)
Another skill references a /skill-name the user doesn't have (likely a v0.x+ addition)
User wants to see "what's new"
After a CHANGELOG entry the user has seen
Troubleshooting — verify user is on the latest version before reporting an issue

Procedure

Read the user's current version from ~/.claude/skills/schengen-master/VERSION

Fetch the latest version from GitHub by hitting the raw file:

curl -s https://raw.githubusercontent.com/torlyai/Schengen-master/main/skills/VERSION

Compare versions:
- If same: report "you're on the latest"
- If user is behind: list what's changed (read CHANGELOG.md)

If updating, ask user permission, then run:

cd ~/.claude/skills/schengen-master && git pull

Confirm the update and show what's new.

Routing rules

Situation	Action
User is up-to-date	No action; confirm
User is behind	Offer to update; explain what's new
User update succeeds	Confirm + suggest re-running last skill if relevant
User update fails (network)	Suggest manual fix; provide URL
User on dev / fork	Note that they're on a non-standard install; don't blindly pull

Common pitfalls

Pitfall	Why it hurts	Fix
Auto-updating without permission	Surprises user mid-session	Always confirm
Updating mid-application	Could change skill behaviour	Wait until end of session
Trying to update during network outage	Fails silently	Show fetch errors to user
User has local edits	`git pull` may conflict	Suggest backup before updating
Update brings breaking changes	User flow broken	Read CHANGELOG migration notes

Notes for maintainers

Version comparison is simple string comparison; for 1.0.0 → 1.0.1 this works. For 1.x → 2.x, double-check semver.
For user reports of "skill X doesn't exist," check their version first via this skill.
The git pull operation can fail in offline / firewalled environments; degrade gracefully and tell user to update manually.
For users on a custom install location (SCHENGEN_SKILLS_DEST=~/foo), git path is ~/foo not ~/.claude/skills/schengen-master — verify.
Always show CHANGELOG diff before pulling so user knows what they're getting.
For users on forks, recommend git fetch upstream && git diff upstream/main rather than blind pull.
