Config Update

When the operator wants to change system configuration, use this skill.

Supported Configuration Changes

• mode: "warmup" or "steady_state"
• quiet_hours_start / quiet_hours_end: hour (0-23)
• active_hours_start / active_hours_end: hour (0-23)
• daily_post_limit / daily_comment_limit / daily_like_limit: integer
• topics: comma-separated list of topic keywords
• timing_randomization_range_minutes: min-max (e.g., "15-60")

Parse Operator Commands

Examples:

• "Switch to steady-state mode" → {"mode": "steady_state"}
• "Set quiet hours to 10pm-7am" → {"quiet_hours_start": 22, "quiet_hours_end": 7}
• "Change daily like limit to 15" → {"daily_like_limit": 15}

Update via Webhook

WEBHOOK_URL="http://localhost:5678/webhook/config-update"
TIMESTAMP=$(date +%s)
BODY='{"action":"update_config","variables":'"$VARIABLES_JSON"'}'

SIGNATURE="sha256=$(echo -n "$BODY" | openssl dgst -sha256 -hmac "$N8N_WEBHOOK_SECRET" | awk '{print $2}')"

RESPONSE=$(curl -s -X POST "$WEBHOOK_URL" \
  -H "Content-Type: application/json" \
  -H "X-Signature: $SIGNATURE" \
  -H "X-Timestamp: $TIMESTAMP" \
  -d "$BODY")

"Updated configuration: [list of changed variables and new values]."

Note: Configuration is stored in n8n Custom Variables. The n8n API key stays inside n8n — this skill calls the config-update webhook, not the n8n REST API directly.
