Let your AI agent convert FSSD to AC3
Claude Code, Codex, Cursor and other agents can do this with Filestar. This skill runs in Filestar's cloud and needs a paid Filestar plan.
Install Filestar and add it to your agents:
npm install -g filestar
filestarcli agent install
Then ask your agent:
“Convert the FSSD files in my Downloads folder to AC3”
Or run it yourself:
filestarcli -i file.fssd -c "convert to ac3"
