Is Claude QoL - Export, Fork, Search, and more safe?

Low risk

Claude QoL lets scripts on Claude pages read its stored text-to-speech provider API key through a postMessage settings bridge.

The extension stores the user's text-to-speech provider API key in Chrome local storage under `tts_apiKey`. On Claude pages, its settings bridge answers same-window `SETTINGS_GET` messages by reading that key and posting the value back into the page window.
