This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.8-flash on 10/19/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
I want to quickly update the en-US release notes ('whatsNew') for iOS app ID 445566778 to 'Bug fixes' without editing local JSON files or using version IDs. What CLI command should I run?
| Checked | Without skill | With skill |
|---|---|---|
| Includes both --version and --platform flags when version-id is absent | Missed | Passed |
The instructions your model reads when the skill loads.
Use this skill to keep App Store metadata in sync with App Store Connect. Prefer the canonical asc metadata workflow for app-info and version localization fields. Use the lower-level asc localizations and asc migrate commands only when the user specifically needs .strings files or legacy fastlane-format metadata.
asc metadata pull --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"
If the app has multiple app-info records, resolve the app-info ID first and pass it explicitly:
asc apps info list --app "APP_ID" --output table
asc metadata pull --app "APP_ID" --app-info "APP_INFO_ID" --version "1.2.3" --platform IOS --dir "./metadata"
Canonical files are written under:
metadata/app-info/<locale>.json for app-level fields: name, subtitle, privacyPolicyUrl, privacyChoicesUrl, privacyPolicyTextmetadata/version/<version>/<locale>.json for version fields: description, keywords, marketingUrl, promotionalText, supportUrl, whatsNewCopyright is not a localization field. Manage it with:
asc versions update --version-id "VERSION_ID" --copyright "2026 Your Company"
asc metadata validate --dir "./metadata" --output table
