About ops-voice

ops-voice is a Claude skill for voice-related operations using API calls through curl. It supports phone calls, text-to-speech, audio transcription, and API key setup for Bland AI, ElevenLabs, and Groq.

Key features

  1. 01Places calls through Bland AI
  2. 02Converts text to speech with ElevenLabs
  3. 03Transcribes audio with Groq Whisper
  4. 04Scans and validates API keys

Use cases

  1. 01Make a phone call from a prompt
  2. 02Create an audio file from text
  3. 03Transcribe an audio file
  4. 04Configure and check voice service credentials

MCP support

The skill can use Doppler MCP tools as one source for API credentials; its voice API requests are made with curl.

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/davepoon/buildwithclaude --skill ops-voice

After installing, type/ops-voicein Claude Code to confirm it loaded.

Details

From the project README

OPS:VOICE — Voice Operations

Voice interface commands. All API calls via curl — no SDK dependencies.

Credential resolution order: userConfig → env vars → Doppler MCP tools (mcp__doppler__*) → Doppler CLI fallback (doppler secrets get <KEY> --plain) → password manager


Sub-commands

Parse $ARGUMENTS for the command keyword, then execute:


call [phone] [prompt] — Bland AI phone call

Requires: bland_ai_api_key in userConfig or BLAND_AI_API_KEY env or Doppler.

BLAND_KEY="${BLAND_AI_API_KEY:-$(doppler secrets get BLAND_AI_API_KEY --plain 2>/dev/null || true)}"
PHONE="<extracted from $ARGUMENTS>"
PROMPT="<extracted from $ARGUMENTS or ask user>"
MAX_DURATION="${BLAND_MAX_DURATION:-300}"  # seconds
VOICE="${BLAND_VOICE:-male}"

# Make the call
RESPONSE=$(curl -s -X POST "https://api.bland.ai/v1/calls" \
  -H "authorization: $BLAND_KEY" \
  -H "Content-Type: application/json" \
  -d "{
    \"phone_number\": \"$PHONE\",
    \"task\": \"$PROMPT\",
    \"voice\": \"$VOICE\",
    \"max_duration\": $MAX_DURATION,
    \"record\": true
  }")

CALL_ID=$(echo "$RESPONSE" | python3 -c "import json,sys; print(json.load(sys.stdin).get('call_id',''))" 2>/dev/null)

# Poll for completion (up to 5 min)
if [ -n "$CALL_ID" ]; then
  echo "Call initiated: $CALL_ID"
  for i in $(seq 1 30); do
    sleep 10
    STATUS=$(curl -s "https://api.bland.ai/v1/calls/$CALL_ID" \
      -H "authorization: $BLAND_KEY" | \
      python3 -c "import json,sys; d=json.load(sys.stdin); print(d.get('status',''), d.get('transcripts','')[-1].get('text','') if d.get('transcripts') else '')" 2>/dev/null)
    echo "Status: $STATUS"
    [[ "$STATUS" == completed* ]] && break
  done
fi

Output: Call ID, live status, transcript when complete.


tts [text] [--voice voice_id] [--out file.mp3] — ElevenLabs text-to-speech

Requires: elevenlabs_api_key in userConfig or ELEVENLABS_API_KEY env or Doppler.

EL_KEY="${ELEVENLABS_API_KEY:-$(doppler secrets get ELEVENLABS_API_KEY --plain 2>/dev/null || true)}"
VOICE_ID="${ELEVENLABS_VOICE_ID:-21m00Tcm4TlvDq8ikWAM}"  # Rachel (default)
TEXT="<extracted from $ARGUMENTS>"
OUT_FILE="${OUT_FILE:-/tmp/ops-tts-$(date +%s).mp3}"

# List voices if voice name provided (not an ID)
# Synthesize
curl -s -X POST "https://api.elevenlabs.io/v1/text-to-speech/${VOICE_ID}" \
  -H "xi-api-key: $EL_KEY" \
  -H "Content-Type: application/json" \
  -d "{
    \"text\": \"$TEXT\",
    \"model_id\": \"eleven_monolingual_v1\",
    \"voice_settings\": {\"stability\": 0.5, \"similarity_boost\": 0.75}
  }" \
  --output "$OUT_FILE"

echo "Audio saved to: $OUT_FILE"
# Auto-play on macOS
command -v afplay &>/dev/null && afplay "$OUT_FILE" &

Output: Audio file path. Auto-plays on macOS via afplay.


transcribe [file_path] — Groq Whisper transcription

Requires: groq_api_key in userConfig or GROQ_API_KEY env or Doppler.

GROQ_KEY="${GROQ_API_KEY:-$(doppler secrets get GROQ_API_KEY --plain 2>/dev/null || true)}"
AUDIO_FILE="<extracted from $ARGUMENTS>"

if [ ! -f "$AUDIO_FILE" ]; then
  echo "ERROR: File not found: $AUDIO_FILE"
  exit 1
fi

TRANSCRIPT=$(curl -s -X POST "https://api.groq.com/openai/v1/audio/transcriptions" \
  -H "Authorization: Bearer $GROQ_KEY" \
  -F "file=@$AUDIO_FILE" \
  -F "model=whisper-large-v3" \
  -F "response_format=json" | \
  python3 -c "import json,sys; print(json.load(sys.stdin).get('text',''))" 2>/dev/null)

echo "$TRANSCRIPT"

Output: Transcript text printed to stdout.


setup — Configure voice API keys

Before asking for anything, auto-scan ALL sources in a single background batch:

# Env vars
printenv BLAND_AI_API_KEY BLAND_API_KEY ELEVENLABS_API_KEY GROQ_API_KEY 2>/dev/null

# Shell profiles
grep -h 'BLAND\|ELEVENLABS\|GROQ' ~/.zshrc ~/.bashrc ~/.zprofile ~/.envrc 2>/dev/null | grep -v '^#'

# Doppler — ALL projects
for proj in $(doppler projects --json 2>/dev/null | jq -r '.[].slug'); do
  for cfg in dev stg prd; do
    doppler secrets --project "$proj" --config "$cfg" --json 2>/dev/null | \
      jq -r --arg proj "$proj" --arg cfg "$cfg" 'to_entries[] | select(.key | test("BLAND|ELEVENLABS|GROQ"; "i")) | "\(.key)=\(.value.computed | .[0:12])... (doppler:\($proj)/\($cfg))"'
  done
done

# Dashlane
dcli password bland --output json 2>/dev/null | jq -r '.[] | select(.password != null) | "\(.title): key found"'
dcli password elevenlabs --output json 2>/dev/null | jq -r '.[] | select(.password != null) | "\(.title): key found"'
dcli password groq --output json 2>/dev/null | jq -r '.[] | select(.password != null) | "\(.title): key found"'

# Keychain
security find-generic-password -s "bland-ai-api-key" -w 2>/dev/null
security find-generic-password -s "elevenlabs-api-key" -w 2>/dev/null
security find-generic-password -s "groq-api-key" -w 2>/dev/null

Present all findings. Only prompt for keys NOT found in any source. Then validate each found key in background:

  1. Bland AI: curl -s -H "authorization: $KEY" https://api.bland.ai/v1/me — check balance
  2. ElevenLabs: curl -s -H "xi-api-key: $KEY" https://api.elevenlabs.io/v1/voices?page_size=1 — list voices
  3. Groq: curl -s -H "Authorization: Bearer $KEY" https://api.groq.com/openai/v1/models — list models

Report: [service] ✓ connected or [service] ✗ invalid key — [error]


Execution

  1. Resolve the sub-command from $ARGUMENTS (first word: call / tts / transcribe / setup)
  2. Resolve credentials in order: env → Doppler
  3. Execute the matching curl block above
  4. If a required key is missing and setup was not invoked, suggest /ops:ops-voice setup
