Tools

scripts/hifly_client.py

The main entry point for all operations.

Usage

# List available public avatars
python scripts/hifly_client.py list_public_avatars

# List available public voices
python scripts/hifly_client.py list_public_voices

# Create a video with a public avatar (TTS)
python scripts/hifly_client.py create_video --type tts --text "Hello world" --avatar "avatar_id_or_alias" --voice "voice_id_or_alias"

# Create a video with a public avatar (Audio URL or File)
python scripts/hifly_client.py create_video --audio "https://... or path/to/audio.mp3" --avatar "avatar_id_or_alias"

# Create a talked photo video using bundled assets
python scripts/hifly_client.py create_talking_photo --image assets/avatar.png --title "Bundled Avatar"

# Clone a voice using bundled assets
python scripts/hifly_client.py clone_voice --audio assets/voice.MP3 --title "Bundled Voice"

# Check status of generated tasks
python scripts/hifly_client.py check_task --id "TASK_ID"

# Manage local aliases (saved in memory.json)
python scripts/hifly_client.py manage_memory add my_avatar "av_12345"
python scripts/hifly_client.py manage_memory list

Examples

1. Create a simple greeting video

# First find a voice and avatar
python scripts/hifly_client.py list_public_avatars
python scripts/hifly_client.py list_public_voices

# Generate
python scripts/hifly_client.py create_video --type tts --text "Welcome to our service." --avatar "av_public_01" --voice "voice_public_01"

2. Use a custom talking photo

# Create the avatar from an image URL
python scripts/hifly_client.py create_talking_photo --image "https://mysite.com/photo.jpg" --title "CEO Photo"
# Output will give you an Avatar ID, e.g., av_custom_99

# Save it to memory
python scripts/hifly_client.py manage_memory add ceo av_custom_99

# Generate video using the new avatar
python scripts/hifly_client.py create_video --type tts --text "Here is the quarterly report." --avatar ceo --voice "voice_public_01"

Agent Behavior Guidelines

When assisting users with video generation, follow these guidelines:

Voice Selection Required

Video generation requires both text AND a voice. If the user provides text but no voice:

  1. Check local memory first: Run manage_memory list to see if the user has saved any voice aliases.

  2. Ask the user to choose:

    • "I see you want to create a video with the text '[text]'. Which voice would you like to use?"
    • If they have saved voices: "You have these saved voices: [list]. Or would you prefer a public voice?"
    • If no saved voices: "Would you like to use a public voice, or clone your own voice from an audio sample first?"

  3. Help them select:

    • To see public voices: list_public_voices
    • To clone a voice: clone_voice --audio [file] --title [name]

Complete Workflow Example

For a prompt like "Create a talking photo video from my photo saying 'this is my AI twin'":

  1. Ask: "Which voice would you like for your AI twin? You can use a public voice or clone your own."
  2. If they want to clone: Help them with clone_voice
  3. Create the talking photo with both text and voice: 
    python scripts/hifly_client.py create_talking_photo \
  --image user_photo.jpg \
  --text "this is my AI twin" \
  --voice SELECTED_VOICE_ID \
  --title "My AI Twin"

Saving for Later

After creating avatars or cloning voices, offer to save them:

python scripts/hifly_client.py manage_memory add my_avatar AVATAR_ID --kind avatar
python scripts/hifly_client.py manage_memory add my_voice VOICE_ID --kind voice
