Auto-publish to Netlify with OG preview to Telegram

A skill that takes a vibe-coded HTML artifact and: (1) deploys it to Netlify, (2) generates a styled web-preview cover image in the brand style, (3) sends the link to the founder's Telegram saved-messages with the cover card preview. Single voice prompt: "Deploy this to Netlify in our brand style. Make a web cover preview card. Send the link to my saved messages." A "scan for leaked secrets before deploy" guardrail runs first.

Internal demos go from "I'll send the link tomorrow" to "you'll have the link in 30 seconds, with a preview card that won't look like a 2010 phpBB forum."

1. Wire a Netlify MCP / personal access token.
2. Wire a Telegram MCP with access to your saved-messages chat.
3. The brand-banner skill (#26) is a prerequisite — the cover comes from it.
4. The deploy skill:

• Reads the target HTML directory
• Runs a grep / gitleaks pass for obvious secret patterns; aborts if found
• Calls Netlify deploy API, captures the URL
• Generates an OG image (1200×630) via the brand-banner skill
• Posts the URL + OG preview to Telegram saved-messages

5. Always include a "no posting to public channel" guardrail in the skill's rules — saved-messages only, unless the user explicitly asks for a channel.

• The "no posting to public channel" guardrail is the case-defining safety. One accidental public post of an internal demo with API keys in the URL kills the pattern for the whole team.
