line-upload

name	line-upload
description	Uploads a processed sticker pack to LINE Creator Market using Playwright browser automation. Use when the user wants to submit stickers to LINE, resume an interrupted upload, handle LINE login/session, set metadata, upload images, set price tier, or submit for review. Don't use for image processing, Telegram publishing, or packs that contain religious content.

Skill: line-upload

Purpose

Upload a fully processed sticker pack to LINE Creator Market: authenticate, create submission, upload images, set metadata + price, and optionally submit for review.

Prerequisites

• Processed images exist in packs/<pack_id>/final/line/, line_main/, line_tab/.
• LINE_EMAIL and LINE_PASSWORD set in .env (or interactive login available).
• Playwright installed: playwright install chromium.
• For first run: a display is available (headful mode required for QR/OTP login).

Steps

Step 1 — Pre-flight content check

Run the content gate before touching the browser. This prevents wasting time uploading a pack that LINE will reject.

python3 scripts/line_preflight_check.py \
    --pack-dir packs/<pack_id>/final \
    --title "<title>" \
    --description "<description>"

If the check fails, report the exact banned keyword and field to the user. Do not proceed unless the user passes --skip-preflight explicitly. See references/line-content-policy.md for the full banned-keyword list.

Step 2 — Verify image assets

Run the asset checker to confirm all required LINE images are present and within spec before launching the browser:

python3 .opencode/skills/line-upload/scripts/check_line_assets.py "<pack_id>"

Fix any reported errors before continuing.

Step 3 — Determine login mode

Check whether a saved session exists:

ls ~/.line-sticker-automation/storage_state.json 2>/dev/null \
  && echo "SESSION EXISTS" || echo "NO SESSION"

• Session exists → proceed headless (Step 4a).
• No session → must run headful for interactive login (Step 4b).

Step 4a — Upload headless (session exists)

Clear any stale progress from a previous run before starting:

rm -f ~/.line-sticker-automation/progress.json

Then run the upload and submit in one command:

python3 scripts/line_uploader.py \
    --pack-dir packs/<pack_id>/final \
    --title "<title>" \
    --description "<description>" \
    --submit

Step 4b — Upload headful (first login)

python3 scripts/line_uploader.py \
    --pack-dir packs/<pack_id>/final \
    --title "<title>" \
    --description "<description>" \
    --headful --dry-run

Instruct the user to complete the QR code or OTP login in the browser window. Session is saved automatically to ~/.line-sticker-automation/storage_state.json. After login succeeds, rerun without --headful for the actual submission.

Step 5 — Resume interrupted upload

If a previous upload was interrupted, check for saved progress:

cat ~/.line-sticker-automation/progress.json 2>/dev/null

If progress exists and the LINE draft was partially created, resume from the last completed step:

python3 scripts/line_uploader.py --resume --headful

If the LINE draft was not created (the upload failed before the draft step), delete the stale progress file and restart from Step 4a:

rm -f ~/.line-sticker-automation/progress.json

Step 6 — Confirm submission

After a successful run, inform the user:

• Submission is under LINE review (typically 3–7 business days).
• Review status is visible at: https://creator.line.me/my/LQu3ADYzrcqp2KCs/sticker/
• Screenshots of each automation step are saved to automation/screenshots/.

Error Handling

Error	Resolution
Pre-flight banned keyword detected	Fix the title/description, or use --skip-preflight (not recommended)
Session expired / 401 on LINE	Delete ~/.line-sticker-automation/storage_state.json and rerun with --headful
Playwright timeout on selector	Increase SELECTOR_TIMEOUT in automation/config.py; check automation/screenshots/ for visual state
Sticker image dimension mismatch	Rerun process-pipeline skill; LINE requires exactly 370×320 px
Main image size wrong	Must be 240×240 px PNG — check packs/<pack_id>/final/line_main/
Tab icon size wrong	Must be 96×74 px PNG — check packs/<pack_id>/final/line_tab/
Upload stuck at image step	Delete ~/.line-sticker-automation/progress.json and restart
Religious content rejection after submission	Pack was submitted before pre-flight was added; LINE rejects automatically
