#!/usr/bin/env node
// Picks a "skill of the week" deterministically (rotates through the
// production-tier skills by ISO week), composes ready-to-post copy for X and
// LinkedIn, and:
//   - writes web/skill-of-the-week.json (for the site / README to display)
//   - appends the posts to the GitHub Actions job summary
//   - if POST_WEBHOOK_URL is set, POSTs { text, network } so you can wire it to
//     Zapier / Make / Buffer / a Slack webhook to auto-publish.
//
// Run locally:  node scripts/skill-of-the-week.mjs
