Asc Marketing Manager

Workflow

Use this skill to update App Store Connect text metadata and screenshot assets with a dry-run-first workflow.

Text Metadata Workflow

1. Confirm the target app, version, and credential env file.
2. If using Google Sheets, read references/google-sheet-localizations.md first.

• sheet ID from ASC_SHEET_ID
• tab from ASC_SHEET_NAME; if omitted, use the confirmed target version
• if ASC_SHEET_ID is missing or the spreadsheet cannot be found, create a native Google

Sheet with the Google Sheets connector before asking the user to fill copy

• after reading sheet values through the connector, use the dependency-free mapper in

lib/sheet-mapper.mjs to convert the 2D range into desired JSON

• new sheets should follow the default localization layout: a Pages tab plus one version tab

with headers Name, Subtitle, Promotional Text, Description, What's new, Keywords

• compare the sheet-derived locales against the exact ASC locales already present on the target

app/version before apply; if ASC has sibling locales such as es-MX vs es-ES, pt-PT vs pt-BR, or en-GB vs en-US that the sheet did not cover, stop and clarify whether to add explicit rows or reuse copy through appInfo.fallbacks / version.fallbacks

1. Build a transient desired-state JSON in /private/tmp.

• If the sheet is edited manually after JSON generation or after a dry-run, re-read the sheet,

rerun the mapper, and regenerate JSON before another dry-run or apply.

• For newly added locales, include both appInfo.locales (name, subtitle) and

version.locales in the first desired JSON. Default name from the primary English row unless the app intentionally localizes its brand/title; localize the subtitle.

• App name and subtitle must not include Apple device names such as iPhone, iPad,

Apple Watch, Apple TV, Apple Vision, or Vision Pro; use generic wording like phone, watch, or localized equivalents.

• If App Store Connect rejects app-info create/update because of app state, report the blocked

name/subtitle fields explicitly, then retry/apply a version-locales-only JSON so promotional text, description, what's new, and keywords can still sync.

1. Run the bundled script with --dry-run.

• the dry run now fails on implicit locale-reuse gaps so omitted sibling locales are handled

explicitly instead of being skipped silently

1. Require explicit user confirmation before running --apply. If the user already gave explicit

apply intent before the dry-run, a clean dry-run immediately before apply is sufficient.

1. After apply, rely on the script's re-fetch verification before reporting success.

If the user's prompt does not specify which App Store version to edit or create, stop and ask for the target version before reading sheets or running the script. Use --ensure-version only when the user wants to start a new editable release. Dry-run reports the version creation; apply creates it.

Screenshot Asset Workflow

Use this workflow for App Store screenshots only. App previews, review attachments, build selection, submission, phased release, routing coverage, and rating reset remain future scope.

1. Confirm the target app, version, credential env file, and local screenshot asset folder.
2. Read references/asset-folder-screenshots.md before interpreting folder structure.
3. Run scripts/asc-sync-assets.mjs with --dry-run first.

• The script infers one ASC locale and one screenshot display type from each screenshot path.
• Supported shapes include assets/en-US/APP_IPHONE_67/01-home.png and

assets/APP_IPHONE_67/en-US/01-home.png.

• Use --folder-shape locale-first or --folder-shape display-first when the user wants a

stricter convention; default auto accepts mixed nested folders when each path is unambiguous.

• Filenames with leading numbers determine order, for example 01-home.png, 02-search.png,

10-settings.png.

1. If folder inference is ambiguous, stop and ask the user how locale/display folders should map

before applying.

1. Require explicit user confirmation before running --apply. Apply mode replaces each targeted

ASC screenshot set with the files found in the matching local folder target.

1. After apply, rely on the script's upload commit, ordering, and processing verification before

reporting success.

Scripts

Use scripts/asc-sync-metadata.mjs.

node scripts/asc-sync-metadata.mjs \
  --env ~/.appstoreconnect/my-app.env \
  --desired /private/tmp/asc-desired-metadata.json \
  --version 2.3.0 \
  --ensure-version \
  --dry-run

node scripts/asc-sync-metadata.mjs \
  --env ~/.appstoreconnect/my-app.env \
  --desired /private/tmp/asc-desired-metadata.json \
  --version 2.3.0 \
  --ensure-version \
  --apply

The script syncs App Store Connect only. It does not read or create Google Sheets directly.

Use scripts/asc-sync-assets.mjs for screenshots:

node scripts/asc-sync-assets.mjs \
  --env ~/.appstoreconnect/my-app.env \
  --assets ./AppStoreScreenshots \
  --version 2.3.0 \
  --dry-run

node scripts/asc-sync-assets.mjs \
  --env ~/.appstoreconnect/my-app.env \
  --assets ./AppStoreScreenshots \
  --version 2.3.0 \
  --apply

Desired JSON

Read references/desired-json-schema.md before creating desired-state JSON by hand. The current nested shape separates appInfo.locales, version.locales, version attributes, and review fields. The old top-level locales shape remains supported for promotionalText and whatsNew.

appInfo.locales (name, subtitle) and version.locales (promotional text, description, keywords, What's New, URLs) are separate ASC resources. If app-level name or subtitle changes are rejected due to App Store Connect state, rerun a version-locales-only dry-run/apply so allowed version metadata can still sync.

Credentials

Read references/app-store-connect-credentials.md before helping a user set up credentials. Never print full key IDs, issuer IDs, JWTs, .p8 contents, or env files containing secrets. Tell users to follow the least privilege principle for App Store Connect API keys. Recommend the Marketing role for this skill's current metadata workflows, and do not request or recommend Full Access.

Safety Rules

• Always dry-run first.
• Do not run --apply until the user explicitly asks for it after a clean dry-run.
• Screenshot apply mode replaces targeted ASC screenshot sets; make the destructive replacement

explicit when summarizing a dry run.

• Keep .env and .p8 files outside repos.
• Do not commit desired JSON if it contains unreleased marketing copy.
• Do not print review passwords, JWTs, .p8 contents, or env files containing secrets.
• Treat app preview, build selection, review attachment, submission, phased-release creation,

routing coverage, and rating reset as future/planning scope.
