Example prompt template:

Install npx skills add google-gemini/gemini-skills --skill gemini-api-cli -y and test the voice or audio feature in this project end-to-end without a physical mic. Find how the app opens microphone capture, generate spoken WAV test files with gemini-api tts, and launch headless Chrome with --use-fake-ui-for-media-stream --use-fake-device-for-media-stream --use-file-for-fake-audio-capture=/abs/path/voice.wav%noloop. Click the mic button so getUserMedia streams the WAV from 0.0s and verify the feature works.
