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 | $0.00019 | $0.05443 |
| Opus 5 | $0.00010 | $0.02721 |
| Sonnet 5 | $0.00004 | $0.01089 |
| Haiku 4.5 | $0.00002 | $0.00544 |
Grade A, and why
webhook-setup scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Webhook Setup
When to Use
Use this skill when setting up webhook endpoints to receive inbound messages, delivery status updates, or template approval notifications from Zavu.
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.
Webhook Types
- Sender Webhooks: Message events (inbound, delivery status, templates) - configured per sender
- Project Webhooks: Project-level events (partner invitations) - one per project

message.sent |
Outbound | Message sent to carrier |
message.delivered |

Configure Webhook via SDK
TypeScript - Create Sender with Webhook
const sender = await zavu.senders.create({
name: "My Sender",
phoneNumber: "+15551234567",
webhookUrl: "https://your-app.com/webhooks/zavu",
webhookEvents: ["message.inbound", "message.delivered", "message.failed"],
});
// Store sender.webhook.secret securely - only shown once!
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.

webhook-setup is a skill published in the GitHub repository zavudev/zavu-skills (1 stars, last pushed 10d ago), licensed Apache-2.0.
