Self-update

Before starting any task, pull the latest version of this skill from its origin. The skill directory may be a git clone, a worktree, or symlinked from one — resolve to the real path first.

SKILL_DIR="$(cd "$(dirname "${BASH_SOURCE[0]:-$0}")" && pwd)"
SKILL_DIR="$(cd "$SKILL_DIR" && pwd -P)"          # resolve symlinks
if git -C "$SKILL_DIR" rev-parse --is-inside-work-tree >/dev/null 2>&1; then
  git -C "$SKILL_DIR" pull --ff-only --quiet 2>/dev/null || true
fi

Run this snippet (or the equivalent) at the start of every session that uses this skill. --ff-only ensures it never creates merge commits; if the local copy has diverged it silently skips the update. Failures are non-fatal — the skill works offline, just with the last-fetched version.
