appstore-metadata-sync: Data & Analytics for AI Agents | OpenAgentSkill

Overview

App Store metadata JSON: edit, validate, push, or sync canonical `./metadata`, plus legacy fastlane migration via `asc migrate`. Excludes translation-first work, standalone release notes, and IAP/subscription names.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

App Store Metadata Sync

Prefer canonical asc metadata JSON for app-info and version fields. Use .strings or fastlane flows only when specifically needed.

Use appstore-metadata-localizer when the main work is translation/adaptation across locales. Use appstore-release-notes-writer for What's New copy. Use appstore-subscription-localizer for subscription, group, or IAP display-name localizations.

Command Plan Helper

For a deterministic dry-run command plan, run the helper from the plugin root:

python3 "$PLUGIN_ROOT/skills/appstore-metadata-sync/scripts/metadata_sync_plan.py" \
  --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" \
  --app-info "APP_INFO_ID" --version-id "VERSION_ID" \
  --include-keywords --keywords-csv "./keywords.csv"

The helper prints commands only; it does not call ASC, mutate metadata, or read credentials. Pass --json for machine-readable output. Pass --confirming-actions only after manually verifying generated --confirm commands.

Workflow

Pull canonical metadata JSON into ./metadata before editing unless the user already provided a fresh metadata tree.
Resolve APP_INFO_ID when multiple app-info records exist.
Edit the owning JSON fields: app-info fields for name/subtitle/privacy text and version fields for description, keywords, marketing URL, promotional text, support URL, and What's New.
Validate locally, then run push --dry-run; apply/push without dry-run only after the diff and target app/version are confirmed.
Use alternate .strings or fastlane migration flows only for legacy repos or explicit user requests.

Limits: name/subtitle 30, keywords 100, description/What's New 4000, promotional text 170. Use table output for human verification and JSON for automation.

# App Store Metadata Sync

Prefer canonical `asc metadata` JSON for app-info and version fields. Use `.strings` or fastlane flows only when specifically needed.

Use `appstore-metadata-localizer` when the main work is translation/adaptation across locales. Use `appstore-release-notes-writer` for What's New copy. Use `appstore-subscription-localizer` for subscription, group, or IAP display-name localizations.

## Command Plan Helper

For a deterministic dry-run command plan, run the helper from the plugin root:

```bash
python3 "$PLUGIN_ROOT/skills/appstore-metadata-sync/scripts/metadata_sync_plan.py" \
--app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" \
--app-info "APP_INFO_ID" --version-id "VERSION_ID" \
--include-keywords --keywords-csv "./keywords.csv"
```

The helper prints commands only; it does not call ASC, mutate metadata, or read credentials. Pass `--json` for machine-readable output. Pass `--confirming-actions` only after manually verifying generated `--confirm` commands.

## Workflow

1. Pull canonical metadata JSON into `./metadata` before editing unless the user already provided a fresh metadata tree.
2. Resolve `APP_INFO_ID` when multiple app-info records exist.
3. Edit the owning JSON fields: app-info fields for name/subtitle/privacy text and version fields for description, keywords, marketing URL, promotional text, support URL, and What's New.
4. Validate locally, then run `push --dry-run`; apply/push without dry-run only after the diff and target app/version are confirmed.
5. Use alternate `.strings` or fastlane migration flows only for legacy repos or explicit user requests.

Limits: name/subtitle 30, keywords 100, description/What's New 4000, promotional text 170. Use table output for human verification and JSON for automation.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: MIT

Dependency or permission surface needs review
Permission surface may require sandboxing
SKILL.md does not include a prerequisites section for installing/configuring the `asc` CLI or handling authentication before running commands.
SKILL.md implies dry-run and confirmation are required, but it does not explicitly mark live mutating commands such as push, apply, keyword apply, or migrate import with a clear 'requires human approval' warning.
Low GitHub adoption signal
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
GitHub adoption: 45 GitHub stars
