Usage/Commands

Show current config:

python {skill_path}/update_config.py --show

Update a value (dot-notation for key path):

python {skill_path}/update_config.py --set "llm.deepseek.apiKey" "sk-xxx"

Examples:

# Change LLM provider
python {skill_path}/update_config.py --set "llm.provider" "claude"

# Set Tavily API key
python {skill_path}/update_config.py --set "tavily.apiKey" "tvly-xxx"

python {skill_path}/update_config.py --set "web.port" "8080"

# Set email credentials
python {skill_path}/update_config.py --set "skills.email.senderEmail" "me@gmail.com"
python {skill_path}/update_config.py --set "skills.email.senderPassword" "app-password"

After updating, tell the user the change was saved and whether a restart is needed to take effect.

Notes

  • Uses bundled 
    update_config.py
    to read and update pythonclaw.json
  • API keys, passwords, and tokens are masked when displaying config
  • Only 
    pythonclaw.json
    is modified — no other files
