Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.02913 |
| Opus 5 | $0.00016 | $0.01456 |
| Sonnet 5 | $0.00006 | $0.00583 |
| Haiku 4.5 | $0.00003 | $0.00291 |
Grade A, and why
vobiz-audio-streams 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 12d 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.

Vobiz Audio Streams skill
Use this for AI voice agents, real-time transcription, custom STT/TTS pipelines, or any workflow that needs raw audio frames rather than just recordings.
How it works
- During a call, your VobizXML answer handler returns a
<Stream bidirectional="true">wss://your-server/ws</Stream>verb. - Vobiz opens a WebSocket to your server and sends a single
startevent withcallId,streamId, andmediaFormat. - Audio frames flow Vobiz → your server as
mediaevents (~50 per second per track, 20 ms each). - For bidirectional streams, your server sends
playAudioevents back, pluscheckpoint,clearAudio, andstopcontrol messages. - When the call ends, the WebSocket closes - there is no inbound
stopevent.
Two ways to start a stream
| Approach | When to use |
|---|---|
<Stream> XML verb |
The call is being set up by your answer handler. Best for AI agents that own the call from the first ring. Bidirectional playback requires this path. |
REST POST .../Stream/ |
The call is already live and you want to attach (or fork) audio mid-call - e.g. start transcription after a transfer. Returns a stream_id you can later list/get/stop. |
REST streams are forks: bidirectional=true over REST still requires audio_track=inbound. For full duplex voice agents, prefer the XML verb.
REST endpoints
Base: https://api.vobiz.ai/api/v1. Auth headers: X-Auth-ID, X-Auth-Token.
| Op | Method + Path | Notes |
|---|---|---|
| Start stream | POST /Account/{auth_id}/Call/{call_uuid}/Stream/ |
Body needs service_url; returns stream_id (202). |
| List streams | GET /Account/{auth_id}/Call/{call_uuid}/Stream/ |
Active + stopped, paginated (limit/offset). |
| Get stream | GET /Account/{auth_id}/Call/{call_uuid}/Stream/{stream_id}/ |
Full Stream object; 404 if unknown. |
| Stop one stream | DELETE /Account/{auth_id}/Call/{call_uuid}/Stream/{stream_id}/ |
204; leaves other forks running. |
| Stop all streams | DELETE /Account/{auth_id}/Call/{call_uuid}/Stream/ |
204; tears down every fork on the call. |
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.

vobiz-audio-streams is a skill published in the GitHub repository vobiz-ai/Agent-Skills (2 stars, last pushed 23d ago), licensed MIT. It adds 32 tokens to every session and 2,913 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
