What's inside

The instructions your model reads when the skill loads.

SKILL.md432 lines2 files

vc-update

Output style: Follow process/development-protocols/communication-standards.md — answer-first, plain language, no unexplained jargon, TL;DR on long responses.

Pull the latest agent harness improvements from the remote vibecode-pro-max-kit repository into the current project.

When to Use

After being told a new harness version is available
Periodically to check for updates
After bootstrapping a project with vc-setup and wanting the latest improvements

Workflow

Follow these steps exactly. Do NOT skip the dry-run or confirmation step.

Step 1: Check Worktree Status

Run git status --porcelain in the project root.

If output is non-empty: warn the user that they have uncommitted changes and suggest git stash or committing first. Do not block -- continue after warning.
If output is empty: proceed silently.

Step 2: Read Current Version

Read the file .vc-version in the project root.

If it exists: store its contents as currentVersion (a semver string like 2.0.4).
If it does not exist: set currentVersion to "0.0.0" (treat as first update).

Step 3: Clone Remote Repository

# Respect VC_KIT_SOURCE override (local path or alternate URL).
# When unset, defaults to the official remote.
KIT_SOURCE="${VC_KIT_SOURCE:-https://github.com/withkynam/vibecode-pro-max-kit.git}"
VC_UPDATE_TMPDIR="/tmp/vc-update-$(date +%s)"
git clone --local --depth 1 --quiet "$KIT_SOURCE" "$VC_UPDATE_TMPDIR" 2>/dev/null \
  || git clone --depth 1 --quiet "$KIT_SOURCE" "$VC_UPDATE_TMPDIR"
# Note: --local is a no-op for remote URLs (git ignores it); the fallback covers all cases.
