Metadata Sync

Use this skill when you need to update store listings, manage screenshots and graphics, or sync metadata from local directories.

Store listings

List all locales

gpc listings list --package com.example.app

Get a specific locale

gpc listings get --locale en-US --package com.example.app

Update listing fields

gpc listings update --locale en-US \
  --title "My App" \
  --short-description "A short tagline" \
  --full-description "Full store description here" \
  --package com.example.app

Sync from directory

gpc listings sync --dir ./metadata --package com.example.app

Images and screenshots

Image types

phoneScreenshots, sevenInchScreenshots, tenInchScreenshots, tvScreenshots, wearScreenshots, featureGraphic, icon, tvBanner, promoGraphic

List images

gpc images list --locale en-US --type phoneScreenshots --package com.example.app

Upload image

gpc images upload --locale en-US --type phoneScreenshots --file screenshot1.png --package com.example.app
gpc images upload --locale en-US --type featureGraphic --file feature.png --package com.example.app
gpc images upload --locale en-US --type icon --file icon.png --package com.example.app

Delete specific image

gpc images delete --locale en-US --type phoneScreenshots --sha1 abc123 --package com.example.app

Delete all images of a type

gpc images delete-all --locale en-US --type phoneScreenshots --package com.example.app

Sync images from directory

gpc images sync --dir ./screenshots --package com.example.app

Multi-language workflow

1. Export current listings:

gpc listings list --package com.example.app -o json > listings.json

2. Update each locale:

gpc listings update --locale ja --title "マイアプリ" --package com.example.app
gpc listings update --locale de --title "Meine App" --package com.example.app

3. Upload locale-specific screenshots:

gpc images upload --locale ja --type phoneScreenshots --file ja_screenshot1.png --package com.example.app

Agent behavior

• Show current listing before overwriting (gpc listings get --locale <locale>).
• Confirm with user before bulk updates across multiple locales.
• Use --dry-run when syncing from directories if available.
• Validate image dimensions match Google Play requirements before uploading.

Notes

• Google Play requires at least 2 phone screenshots per locale.
• Feature graphic must be 1024x500 pixels.
• Icon must be 512x512 pixels.
• Use gpc listings sync --dir for Fastlane-compatible directory structures.
