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 | $0.00036 | $0.03227 |
| Opus 5 | $0.00018 | $0.01614 |
| Sonnet 5 | $0.00007 | $0.00645 |
| Haiku 4.5 | $0.00004 | $0.00323 |
Grade A, and why
voice-agent 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 317 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Voice Agents
A voice agent answers a phone call, holds a conversation, calls your code when
it needs to do something, and hands off to a person when it should. It is the
same agent object as a messaging agent, with a voice block on it.
Zavu runs the whole pipeline: speech recognition, the agent's model, speech synthesis, and interruption handling. You supply the prompt and the skills.
One thing to know before anything else: voice is the channel where tools
actually run. On plain text the model is not offered tools at all (see
ai-agent). If your agent has to do something, voice and flows are where
that works today.
Senders vs accounts (one paragraph)
A Sender is the API handle you pass as Zavu-Sender; accounts (a WhatsApp Business Account, a Facebook Page, a Telegram bot, a phone number) are the connections it routes — and what bills. Senders are free. Connecting an account in the dashboard auto-creates its sender; find it with GET /v1/senders and trust its channels array for what it can send. See the channel-setup skill for the full model.
Fastest path: take a factory agent
Zavu ships working voice agents. Talking to one on zavu.dev and then owning its code is the same agent.
npx zavudev agents catalog # what's available
npx zavudev agents pull kepler --dir kepler # scaffold it locally
# booking agents: add --calendar calcom for a working Cal.com client
cd kepler
npm install # types + local runs
npx zavudev senders list # find your sender id
npx zavudev fn secrets set SENDER_ID <senderId>
npx zavudev deploy
npx zavudev agents list # confirm what actually landed
An agent can answer on more than one number. Connect them by id:
npx zavudev agents senders connect --agent <agentId> --sender <senderId>
agents pull writes a real TypeScript project: index.ts with the agent and
its skills, a tsconfig.json, and a local stand-in for @zavudev/functions so the
project typechecks and runs on your machine. Edit it freely — the file is yours,
and npx zavudev deploy reconciles whatever it declares.
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.
- 11d ago First seen · 317 lines · 36 tokens per session scan A c0e568ddd9fd
voice-agent is a skill published in the GitHub repository zavudev/zavu-skills (1 stars, last pushed yesterday), licensed Apache-2.0. It adds 36 tokens to every session and 3,227 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.
