voice-call

voice-call is a skill for Claude Code, Codex from SeanHogg/Builderforce.ai. It costs 15 tokens per session (345 once invoked), scanned A, a copy of voice-call, MIT.

A voice-calling interface for starting and managing phone calls through Twilio, Telnyx, Plivo, or a simulated provider. It can send messages during a call and report the call status.

In plain words
What is it for?
Use it to start a call, continue or speak during an existing call, end it, or check its status. A mock provider supports development without network calls.
Why use it?
It removes the need to integrate each phone service separately when an agent needs to communicate by voice.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

voice-call scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Voice Call

Use the voice-call plugin to start or inspect calls (Twilio, Telnyx, Plivo, or mock).

CLI

builderforce voicecall call --to "+15555550123" --message "Hello from BuilderForceAgents"
builderforce voicecall status --call-id <id>

Tool

Use voice_call for agent-initiated calls.

Actions:

  • initiate_call (message, to?, mode?)
  • continue_call (callId, message)
  • speak_to_user (callId, message)
  • end_call (callId)
  • get_status (callId)

Notes:

  • Requires the voice-call plugin to be enabled.
  • Plugin config lives under plugins.entries.voice-call.config.
  • Twilio config: provider: "twilio" + twilio.accountSid/authToken + fromNumber.
  • Telnyx config: provider: "telnyx" + telnyx.apiKey/connectionId + fromNumber.
  • Plivo config: provider: "plivo" + plivo.authId/authToken + fromNumber.
  • Dev fallback: provider: "mock" (no network).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
