tari-ootle

tari-ootle is a skill for Claude Code, Codex from tari-project/tari-ootle. It costs 37 tokens per session (13,399 once invoked), scanned A, original, BSD-3-Clause.

Development guidance for Tari Ootle, a platform for building smart contracts—programs that run on a blockchain—in Rust and compiling them to WebAssembly. It explains on-chain components, digital assets, and transactions.

In plain words
What is it for?
It is for writing Rust smart-contract templates, compiling them to WebAssembly, publishing them, and working with assets, components, and signed transactions.
Why use it?
It gives developers the platform-specific concepts and rules needed to build code that can be published and called on the Tari Layer 2 network.

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

tari-ootle 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.

Overview

Tari Ootle is a decentralized application platform built on the Tari Layer 2 network. You build templates (smart contracts) in Rust, compile them to WASM (wasm32-unknown-unknown), publish them to the network, and interact with deployed components (instances of templates) via transactions.

Key concepts:

  • Template — A Rust module annotated with #[template] that defines the logic and state structure. Compiled to WASM and deployed to the network.
  • Component — A live instance of a template on-chain. Holds state (struct fields) and exposes public methods.
  • Resource — A native digital asset (fungible token or non-fungible NFT). Created with ResourceBuilder. Cannot be copied or accidentally destroyed.
  • Vault — An on-chain container that holds exactly one type of resource. Must be stored in a component before the function returns.
  • Bucket — A temporary container for resources during a transaction. Used to move assets between vaults or to/from method calls.
  • Transaction — A set of instructions (CallFunction, CallMethod, etc.) that are signed, submitted, and executed atomically.

Crate ecosystem:

Crate Purpose Used In
tari_template_lib Core template library: prelude, ResourceBuilder, Vault, Bucket, ComponentManager, CallerContext, emit_event, rand, macros (args!, rule!, metadata!) Templates (WASM)
tari_template_lib_types Shared types: Amount, ComponentAddress, ResourceAddress, NonFungibleId, AccessRule, OwnerRule, Metadata Templates & client
tari_ootle_transaction TransactionBuilder and args! macro for constructing transactions Client & tests
ootle-rs Client wallet and Indexer provider: sign, submit, watch transactions; builtin template helpers (faucet) Client apps
tari_template_test_tooling Local test harness (dev-dependency): compile templates to WASM and run against the engine in-process Tests only

Important macro distinction:

  • args! (from tari_template_lib::prelude) — used inside templates for cross-template calls (alias for invoke_args!)
  • args! (from tari_ootle_transaction) — used in test code and client code for TransactionBuilder, TemplateTest::call_function, and call_method. Produces Vec<NamedArg>.

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.

tari-ootle is a skill published in the GitHub repository tari-project/tari-ootle (29 stars, last pushed yesterday), licensed BSD-3-Clause. It adds 37 tokens to every session and 13,399 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-07.
