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 | $0.01511 |
| Opus 5 | $0.00010 | $0.00756 |
| Sonnet 5 | $0.00004 | $0.00302 |
| Haiku 4.5 | $0.00002 | $0.00151 |
Grade A, and why
zavu-rules 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zavu API Context
Zavu is a unified multi-channel messaging API. One API to send messages via SMS, WhatsApp, Telegram, Email, Instagram, and Voice with ML-powered intelligent routing.
SDK Ecosystem

Tooling
| Tool | Purpose | Install |
|---|---|---|
zavu CLI |
Interact with the API from the terminal; manage Zavu Functions (serverless TypeScript on Zavu Cloud) | npx zavudev@latest (no install), or npm install -g zavudev |
@zavudev/functions |
Runtime package for Zavu Functions. Provides defineAgent, defineTool, defineFunction declarative APIs. |
Pre-installed in the function runtime — import { defineAgent } from "@zavudev/functions" (no install needed). |
The CLI is the primary interface for Zavu Functions: serverless TypeScript that runs on Zavu Cloud and lets you declare AI agents + tool handlers in code. See the functions skill for full coverage.

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.

zavu-rules is a skill published in the GitHub repository zavudev/zavu-skills (1 stars, last pushed yesterday), licensed Apache-2.0. It adds 19 tokens to every session and 1,511 once invoked, about $0.0001 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.
