## @id update-chattolib
## @name Update Chattolib
## @description Performs a full vendor refresh of chattolib: downloads the newest (or specified) version, refreshes vendor/, updates docs, and verifies.
## @usage update-chattolib [SPEC]
##   e.g.: `update-chattolib "chattolib[realtime]==0.5.0b4"`
##        `update-chattolib` (uses CHATTOLIB_SPEC from vendor_chattolib.sh)
##
## This skill wraps the steps from vendor_chattolib.sh + AGENTS.md
## so that no vendor files are ever edited manually.

# --- Configuration ---

# PLUGIN_DIR is the project root (set by opencode/Paseo)
PLUGIN_DIR="${PROJECT_DIR:-.}"
SPEC="${1:-}"

# --- Execution ---

# 1. Determine the SPEC value

# 7. Commit note
echo "✅ Done! Version is $VERSION."
echo "💡 Now run 'git diff vendor_chattolib.sh' to update the SPEC floor in vendor_chattolib.sh if needed."
