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 7d 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

openclaw voicecall call --to "+15555550123" --message "Hello from OpenClaw"
openclaw 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.
