Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Access the WhatsApp Business API with managed OAuth authentication. Send messages, manage message templates, handle media, and interact with customers through WhatsApp.

Phone numbers must be in international format without + or leading zeros (e.g., 1234567890) messaging_product must always be set to whatsapp Template messages are required for initiating conversations (24-hour messaging window) Media files must be publicly accessible URLs or uploaded via the Media API Interactive messages support up to 3 buttons or 10 list items Message IDs (wamid) are used to track message status and replies API version v21.0 is current; check Meta docs for latest version IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.
