name	slidev-deck-pipeline
description	Deterministic pipeline for authoring, verifying, exporting, and deploying OpenCoven Slidev decks (the weekly Show'n Spells system and one-off branded decks). Use whenever asked to build, rebuild, update, export, or publish a Slidev slide deck for OpenCoven — weekly meeting decks, launch decks, or explainer decks.

Slidev Deck Pipeline

The single, repeatable path for turning content into a published OpenCoven Slidev deck. Optimize for determinism: same inputs → same deck → same verified dist → same deploy. Author by writing a real .md file with Node's fs.writeFileSync, then run the repo's own scripts to verify and build. Never eyeball-ship.

When to use

Scenario	Use this skill
Weekly Open Coven / Show'n Spells deck	✅ (the canonical path)
One-off launch / explainer deck in the same house style	✅
Rebuilding an existing deck "the standard way"	✅
Exporting a deck to PDF	✅
Deploying a deck to Vercel (show.opencoven.ai)	✅
Non-Slidev copy (tweets, Discord posts)	❌ use the voice/social skills instead

Repo facts (canonical)

• Repo: OpenCoven/open-coven-weekly (local checkout path varies by machine)
• Decks: slides/YYYY-MM-DD.md (a -slug suffix is allowed: YYYY-MM-DD-slug.md)
• Template: slides/template.md
• Theme: theme/ = @opencoven/slidev-theme-coven; referenced from a deck as theme: ../theme
• Static assets: slides/public/ → served at / (images live in slides/public/img/, referenced as /img/<name>)
• Package manager: pnpm
• Deploy: Vercel project open-coven-weekly, aliased to show.opencoven.ai, auto-deploys on push to main

The scripts (this is the deterministic core — always use them)

Command	What it does
pnpm new (node scripts/new-week.mjs)	Scaffolds next Sunday's slides/YYYY-MM-DD.md from template.md, replacing {{DATE}} and {{MONTH_DAY_YEAR}}
pnpm dev	Live Slidev preview of the latest dated deck (auto-resolved)
pnpm build	Build with GitHub-Pages base /open-coven-weekly/
pnpm build:vercel	Build with root base / → publishes slides/dist (this is what Vercel runs)
pnpm export	Installs Chromium, exports the latest deck to PDF
pnpm verify	pnpm test + verify-week + both builds + verify:dist — the full gate
pnpm verify:dist	Confirms built dist/index.html contains the latest deck's frontmatter title

Deck resolution is automatic and deterministic (scripts/deck-utils.mjs): the latest deck is the one with the highest YYYY-MM-DD; on a date tie, the shorter filename wins (so a bare 2026-07-15.md beats a slugged 2026-07-15-draft.md). To make a deck "the live one," give it the latest date and the shortest name.

The deterministic loop (follow in order)

1. Gather content — merged PRs (gh pr list --state merged --limit 30), releases (gh release list), and any Sage brief. Cluster into topics (one topic ≈ one slide).
2. Scaffold — pnpm new (or copy the newest deck as a starting idiom for a slugged one-off).
3. Author the file with Node fs.writeFileSync — NOT shell heredocs/echo (they truncate long content and mangle escapes). See references/authoring.md.
4. Verify — pnpm verify (or at minimum node scripts/verify-week.mjs). Fix every failure. The verifier enforces: no blank slides, a speaker note on every slide, required strings (theme: ../theme, layout: cover, layout: default, discord.gg/opencoven), a frontmatter title:, and the deck's date present in the body.
5. Preview — pnpm dev, spot-check every slide and every image renders in-browser.
6. Commit & push in OpenCoven/open-coven-weekly — git add slides/YYYY-MM-DD.md slides/public/img/<new> then git commit -m "slides: add YYYY-MM-DD Show'n Spells deck" and git push origin main. Vercel auto-deploys. This repo's weekly-deck workflow commits directly to its main branch.
7. Confirm live — curl the production URL, assert HTTP 200 on index and every referenced image.

House slide idiom (match it exactly)

Non-cover slide skeleton:

---
layout: default
---

<div class="label">Section Label</div>

# Title with one *italic* word

<!-- Full presenter sentences, natural spoken tone.
Use <span class="cue">[stage direction]</span> for cues. -->

• Cover: either layout: cover with a .sub line (Show'n Spells · <time> · discord.gg/opencoven), or layout: full for an absolute-positioned full-bleed hero (see references/full-bleed-hero.md).
• Theme classes: .label (section kicker), .card + .card-title (grid cards), .badge-shipped (green, live/merged), .badge-wip (amber, in progress), .cue (speaker-note stage direction).
• Reveals: v-click on cards/list items for progressive reveal.
• Every slide MUST have a <!-- ... --> speaker note. No exceptions — the verifier rejects blanks.
• Arc: Cover → Agenda ("Tonight's Spells") → Shipped (one per cluster) → Live demo stop → Open-floor stops (2–3, scattered) → optional Architecture → Outro (Discord CTA + next-week teaser).

Hard rules (learned the hard way — see references/gotchas.md)

• Author with fs.writeFileSync, never heredoc/echo for deck bodies.
• Images: put files in slides/public/img/, reference as /img/<name>.jpg. Full URLs must be https://. In-browser (pnpm dev / the live Vercel build) renders all images fine.
• PDF export drops early background images (Slidev export-timing bug): it reliably renders only the last image slides. For a perfect PDF, present from the live URL, or composite the PDF from high-res text-slide renders + the JPEGs at their exact page positions. Do NOT claim a clean PDF without opening it page-by-page.
• Deploy target: reuse the existing open-coven-weekly Vercel project. Do NOT spawn throwaway projects (dist, coven-threads-explainer, etc.). If you accidentally do, delete them.
• "Standard format" means the house idiom above — theme ../theme, .label/.card, v-click, speaker notes, the standard arc. When Val says "rebuild the standard way," this is what she means.
