Give your agent a voice. Send text to a Mac running VoxClaw and hear it spoken aloud with OpenAI neural voices or Apple TTS.
Run an offline ASO audit on canonical App Store metadata under `./metadata` and surface keyword gaps using Astro MCP. Use after pulling metadata with `asc metadata pull`.
Guidance for using asc cli in this repo (flags, output formats, pagination, auth, and discovery). Use when asked to run or design asc commands or interact with App Store Connect via the CLI.
Automatically translate and sync App Store metadata (description, keywords, what's new, subtitle) to multiple languages using LLM translation and asc CLI. Use when asked to localize an app's App Store listing, translate app descriptions, or add new languages to App Store Connect.
Sync and validate App Store metadata and localizations with asc, including legacy metadata format migration. Use when updating metadata or translations.
Determine whether an app is ready to submit, then drive the App Store release flow with asc, including first-time submission fixes for availability, in-app purchases, subscriptions, Game Center, and App Privacy.

macOS screenshots often contain hidden Unicode characters (e.g., U+202F narrow no-break space) that cause sips and other tools to fail with "not a valid file". Always sanitize first:
python3 -c "
import os
for f in os.listdir('.'):
clean = f.replace('\u202f', ' ')
if f != clean:
os.rename(f, clean)
print(f'Renamed: {clean}')
"
sips -g pixelWidth -g pixelHeight screenshot.png
Check for alpha channel and color space issues before uploading:
sips -g hasAlpha -g space screenshot.png
App Store Connect rejects screenshots with alpha transparency. Remove it by round-tripping through JPEG:
sips -s format jpeg input.png --out /tmp/temp.jpg
sips -s format png /tmp/temp.jpg --out output.png
rm /tmp/temp.jpg
Batch-strip alpha from all PNGs in a directory:
for f in *.png; do
if sips -g hasAlpha "$f" | grep -q "yes"; then
sips -s format jpeg "$f" --out /tmp/temp.jpg
sips -s format png /tmp/temp.jpg --out "$f"
rm /tmp/temp.jpg
echo "Stripped alpha: $f"
fi
done
