What

A new week in docs/weekly-updates.mdx now posts itself. When the Monday digest merges to main, .github/workflows/changelog-announce.yml runs scripts/changelog-announce.ts, which reads the newest <Update> and posts:

• Slack: the week label, the summary line, the top highlights, "Watch the video" and "Read the notes" links.
• Discord: the video URL (so it plays inline) and an embed with the summary and highlights.

Why

Today the weekly video stops at the docs PR and is never posted anywhere. Auto-posting every release to the community is one of the Discord growth levers we agreed on (Nov 4).

How

• Triggers on pushes to main that touch docs/weekly-updates.mdx, plus a manual run.
• Reposts only when the first <Update> label changed against HEAD^, so fixing a typo in a week that already went out does not post again.
• Each webhook is optional: a missing secret is skipped, so this is safe to merge before the secrets exist.
• Highlights come from **1. Headline.** lines when the digest has a top-5 list, else the first five ## sections (today's format).
• No new dependencies; runs with npx tsx@4, same action pins as the other workflows.

Needs from a repo admin: two secrets, CHANGELOG_SLACK_WEBHOOK_URL (for #changelog-whatsnew-releasenotes) and CHANGELOG_DISCORD_WEBHOOK_URL (Discord #changelog).

Related work

Refs #7453 (the Nov 2-9 digest the dry run below uses). A follow-up updates the changelog-video skill to the v2 look.

Test plan

• Unit tests added: scripts/changelog-announce.test.ts (4 pass), registered in test:scripts
• Dry run on main's real digest (npx tsx scripts/changelog-announce.ts): label "Week of November 2, 2026", the nov02-09 video, the summary and five highlights, in both payloads
• oxfmt --check and oxlint clean on the changed files
• After the secrets are added: workflow_dispatch once to see both posts land
