codeck export — @export lane

Minimum conversation, maximum output. Export the deck to the user's format.

@export owns PDF/PPTX output and export QA.

Write boundaries:

• May write final PDF/PPTX files in the user's project directory
• May write export QA notes to $DECK_DIR/review.md or $DECK_DIR/MEMORY.md
• May update $DECK_DIR/roles/export.md, $DECK_DIR/tasks/tasks.md, and $DECK_DIR/channel/YYYY-MM-DD.md
• Must not edit deck.md, DESIGN.md, custom.css, slides.html, or speech.md
• Export defects that require source changes become proposals in $DECK_DIR/threads/threads.md

Step 1: Status

DECK_DIR="$HOME/.codeck/projects/$(basename "$(pwd)")"
CODECK_SKILL_DIR="${CODECK_SKILL_DIR:-}"
if [ -z "$CODECK_SKILL_DIR" ]; then
  for d in \
    "${CLAUDE_PLUGIN_ROOT}/skills/codeck" \
    "$HOME"/.claude/plugins/cache/*/codeck/*/skills/codeck \
    "$HOME"/.codex/plugins/cache/*/codeck/*/skills/codeck \
    "$HOME/.agents/skills/codeck" \
    "$HOME/.codex/skills/codeck" \
    "$HOME/.claude/skills/codeck"; do
    if [ -d "$d/scripts" ]; then CODECK_SKILL_DIR="$d"; break; fi
  done
fi
[ -n "$CODECK_SKILL_DIR" ] || { echo "codeck skill scripts not found; set CODECK_SKILL_DIR" >&2; exit 1; }
. "$CODECK_SKILL_DIR/scripts/resolve-dirs.sh"
mkdir -p "$DECK_DIR"
mkdir -p "$DECK_DIR/channel" "$DECK_DIR/tasks" "$DECK_DIR/threads" "$DECK_DIR/roles"
bash "$CODECK_SKILL_DIR/scripts/init-room.sh" "$DECK_DIR"
bash "$CODECK_SKILL_DIR/scripts/status.sh" "$DECK_DIR"

Read $DECK_DIR/MEMORY.md, active rows in $DECK_DIR/tasks/tasks.md, and open rows in $DECK_DIR/threads/threads.md. Do not read channel/YYYY-MM-DD.md unless debugging history.

Gate check: if no assembled HTML exists (./*-r*.html), run /codeck to generate/rebuild the deck first.

Before export, claim the work ticket:

@orchestrator
Owner: @export. Task: export latest HTML and run export QA.

@export
I claim the export pass. I will write PDF/PPTX outputs and record any source defects as threads.

Append the exchange to today's channel file and update tasks/tasks.md.

Step 2: Format

Export Format is one allowed Decision Ask moment under /codeck.

Use the shared /codeck Decision Ask Policy. Skip Decision Ask when the user names a target:

• PDF, print, save as PDF → export PDF
• PPTX, PowerPoint, slides file → export PPTX
• all, both → export PDF and PPTX

If the user only says "export", create a non-blocking D-YYYYMMDD-NN decision in threads/threads.md and render once:

codeck needs the export format.

Current read: HTML already exists as the audience preview.

I suggest PDF because it preserves the visual layout and is easiest to share.

A) PDF (recommended)
B) PPTX
C) PDF + PPTX

If the user does not answer or structured AskUser UI is unavailable, export PDF and write assumed default to MEMORY.md.

Do not offer HTML as an export choice. HTML is the preview/source artifact.

Step 3: Export

Find the HTML file (./*-r*.html in the user's project directory), derive baseName.

HTML

Already exists. Open in browser, F for fullscreen, arrows to navigate.

PDF — print from HTML

Use Playwright for WYSIWYG PDF:

npx playwright install chromium 2>/dev/null || true

import { chromium } from 'playwright';
import { resolve } from 'path';
import { readdirSync } from 'fs';
import { pathToFileURL } from 'url';

const html = readdirSync('.').find(f => /-r\d+\.html$/.test(f));
const baseName = html.replace('.html', '');
const browser = await chromium.launch();
const page = await browser.newPage();
await page.goto(pathToFileURL(resolve(html)).toString(), { waitUntil: 'networkidle' });
await page.emulateMedia({ media: 'screen' });
await page.pdf({
  path: `${baseName}.pdf`,
  printBackground: true,
  preferCSSPageSize: true,
  margin: { top: '12mm', right: '12mm', bottom: '12mm', left: '12mm' }
});
await browser.close();
console.log(`done: ${baseName}.pdf`);

Poster assets

.media-poster elements in slides.html are video/audio placeholders. Original file paths are in the caption and deck.md asset manifest.

Default: keep placeholders in export. If user says "embed video", extract path from caption, use slide.addMedia({ path: "..." }) for PPTX.

PPTX — from HTML

Option A (recommended): LibreOffice

CODECK_SKILL_DIR="${CODECK_SKILL_DIR:-}"
if [ -z "$CODECK_SKILL_DIR" ]; then
  for d in \
    "${CLAUDE_PLUGIN_ROOT}/skills/codeck" \
    "$HOME"/.claude/plugins/cache/*/codeck/*/skills/codeck \
    "$HOME"/.codex/plugins/cache/*/codeck/*/skills/codeck \
    "$HOME/.agents/skills/codeck" \
    "$HOME/.codex/skills/codeck" \
    "$HOME/.claude/skills/codeck"; do
    if [ -d "$d/scripts" ]; then CODECK_SKILL_DIR="$d"; break; fi
  done
fi
[ -n "$CODECK_SKILL_DIR" ] || { echo "codeck skill scripts not found; set CODECK_SKILL_DIR" >&2; exit 1; }
. "$CODECK_SKILL_DIR/scripts/resolve-dirs.sh"
[ -n "${CODECK_EXPORT_DIR:-}" ] || { echo "codeck-export not found; set CODECK_EXPORT_DIR" >&2; exit 1; }
EXPORT_SCRIPTS="$CODECK_EXPORT_DIR/pptx/scripts"
python "$EXPORT_SCRIPTS/office/soffice.py" --headless --convert-to pdf ./*-r*.html
python "$EXPORT_SCRIPTS/office/soffice.py" --headless --convert-to pptx ./*-r*.html

Option B (fallback): screenshot embed

If soffice unavailable, use Playwright to screenshot each page, then PptxGenJS to embed screenshots as slides. Read $CODECK_EXPORT_DIR/pptx/pptxgenjs.md for the API.

Step 4: QA (required for PDF/PPTX)

Assume the export has problems. Find them.

PDF

Check: pages complete (no truncation), backgrounds render, fonts display correctly.

PPTX

Generate thumbnails:

CODECK_SKILL_DIR="${CODECK_SKILL_DIR:-}"
if [ -z "$CODECK_SKILL_DIR" ]; then
  for d in \
    "${CLAUDE_PLUGIN_ROOT}/skills/codeck" \
    "$HOME"/.claude/plugins/cache/*/codeck/*/skills/codeck \
    "$HOME"/.codex/plugins/cache/*/codeck/*/skills/codeck \
    "$HOME/.agents/skills/codeck" \
    "$HOME/.codex/skills/codeck" \
    "$HOME/.claude/skills/codeck"; do
    if [ -d "$d/scripts" ]; then CODECK_SKILL_DIR="$d"; break; fi
  done
fi
[ -n "$CODECK_SKILL_DIR" ] || { echo "codeck skill scripts not found; set CODECK_SKILL_DIR" >&2; exit 1; }
. "$CODECK_SKILL_DIR/scripts/resolve-dirs.sh"
[ -n "${CODECK_EXPORT_DIR:-}" ] || { echo "codeck-export not found; set CODECK_EXPORT_DIR" >&2; exit 1; }
EXPORT_SCRIPTS="$CODECK_EXPORT_DIR/pptx/scripts"
python "$EXPORT_SCRIPTS/thumbnail.py" ./*-r*.pptx

Convert to images for detailed check:

python "$EXPORT_SCRIPTS/office/soffice.py" --headless --convert-to pdf ./*-r*.pptx
pdftoppm -jpeg -r 150 *.pdf slide-check

Use subagent to visually inspect screenshots. Focus on: overlapping elements, text overflow, uneven spacing, low-contrast text, differences from HTML original.

Fix loop

1. Find issue → adjust export params or HTML
2. Re-export → re-screenshot → re-check
3. Until one full check finds no new issues

At least one fix-verify cycle before declaring done.

If QA finds a source defect, do not edit source files directly. Add a thread with the affected artifact and suggested owner, then hand off to @design or @review.

After export:

1. Update MEMORY.md Active Context, Latest Channel Summary, Task Index, and Artifacts.
2. Mark the @export task done in tasks/tasks.md.
3. Append the handoff to today's channel file.

Step 5: Done

Export done. Output: {baseName}.pdf / {baseName}.pptx

@export I exported the latest HTML, ran QA, and recorded output paths in memory.
