WaveCap Alerts Skill

Use this skill to manage keyword alert rules in WaveCap.

Authentication Required

Updating alerts requires editor authentication:

bash
TOKEN=$(curl -s -X POST http://localhost:8000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"password": "YOUR_EDITOR_PASSWORD"}' | jq -r '.token')

View Current Alerts

bash
curl -s http://localhost:8000/api/alerts | jq

Response Format

json
{
  "enabled": true,
  "rules": [
    {
      "id": "rule-1",
      "label": "Emergency",
      "phrases": ["emergency", "urgent", "mayday"],
      "playSound": true,
      "notify": true,
      "caseSensitive": false,
      "enabled": true
    }
  ]
}

Update Alerts

The PUT endpoint replaces the entire alerts configuration:

bash
curl -s -X PUT http://localhost:8000/api/alerts \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "enabled": true,
    "rules": [
      {
        "id": "emergency",
        "label": "Emergency",
        "phrases": ["emergency", "mayday", "urgent"],
        "playSound": true,
        "notify": true,
        "caseSensitive": false,
        "enabled": true
      },
      {
        "id": "fire",
        "label": "Fire",
        "phrases": ["structure fire", "brush fire", "fire alarm"],
        "playSound": true,
        "notify": true,
        "caseSensitive": false,
        "enabled": true
      }
    ]
  }' | jq

Common Operations

Add a New Alert Rule

First get existing alerts, then append the new rule:

bash
# Get current config
CURRENT=$(curl -s http://localhost:8000/api/alerts)

# Add new rule using jq
UPDATED=$(echo "$CURRENT" | jq '.rules += [{
  "id": "medical",
  "label": "Medical Emergency",
  "phrases": ["cardiac arrest", "cpr", "unresponsive"],
  "playSound": true,
  "notify": true,
  "caseSensitive": false,
  "enabled": true
}]')

# Update
curl -s -X PUT http://localhost:8000/api/alerts \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d "$UPDATED" | jq

Disable a Rule

bash
CURRENT=$(curl -s http://localhost:8000/api/alerts)
UPDATED=$(echo "$CURRENT" | jq '(.rules[] | select(.id == "rule-id")).enabled = false')
curl -s -X PUT http://localhost:8000/api/alerts \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d "$UPDATED" | jq

Remove a Rule

bash
CURRENT=$(curl -s http://localhost:8000/api/alerts)
UPDATED=$(echo "$CURRENT" | jq '.rules = [.rules[] | select(.id != "rule-to-remove")]')
curl -s -X PUT http://localhost:8000/api/alerts \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d "$UPDATED" | jq

Add Phrases to Existing Rule

bash
CURRENT=$(curl -s http://localhost:8000/api/alerts)
UPDATED=$(echo "$CURRENT" | jq '(.rules[] | select(.id == "emergency")).phrases += ["crisis", "help"]')
curl -s -X PUT http://localhost:8000/api/alerts \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d "$UPDATED" | jq

Disable All Alerts

bash
curl -s -X PUT http://localhost:8000/api/alerts \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"enabled": false, "rules": []}' | jq

View Triggered Alerts in Transcriptions

Transcriptions that triggered alerts have an alerts array:

bash
curl -s "http://localhost:8000/api/streams/{STREAM_ID}/transcriptions?limit=100" | \
  jq '[.transcriptions[] | select(.alerts | length > 0)] | .[] | {timestamp, text, alerts: [.alerts[].ruleLabel]}'

Tips

  • The entire rules array is replaced on PUT - always include all rules you want to keep
  • Use descriptive id values for easy reference
  • Keep caseSensitive: false for most use cases
  • Test phrases with common variations and misspellings
