tari-ootle: Instructions file for Claude Code

CLAUDE.md

tari-ootle CLAUDE.md is an instructions file for Claude Code from tari-project/tari-ootle. It costs 1,387 tokens per session, scanned A, original, BSD-3-Clause.

Project guidance for Tari Ootle, a Rust codebase with wallet applications, transaction components, and supporting libraries. It explains the repository layout, naming, and rules for useful code comments.

In plain words
What is it for?
Use it when changing the wallet daemon, wallet command-line tool, transaction parser, transaction types, template types, or CBOR serialization code.
Why use it?
It helps an agent find the right package and avoid incorrect names or comments that merely describe past changes.

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 CLAUDE.md 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 today.

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.

Tari Ootle - Claude Code Cheatsheet

Project Structure

  • The project is called "Ootle" or "Tari Ootle" (not "DAN" or "Tari DAN")
  • Crates are in crates/, applications in applications/, clients in clients/
  • Wallet daemon package: tari_ootle_walletd (in applications/tari_walletd/)
  • Wallet CLI: tari_wallet_cli (in applications/tari_wallet_cli/)
  • Transaction manifest parser: tari_transaction_manifest (in crates/transaction_manifest/)
  • Transaction types/instructions: tari_ootle_transaction (in crates/transaction/)
  • Template lib types (OwnerRule, RistrettoPublicKeyBytes, etc.): tari_template_lib_types (in crates/template_lib_types/)
  • CBOR serialization: tari_bor (in crates/tari_bor/) - wraps ciborium, re-exports serde

Code Comments

IMPORTANT: Comments must help a future reader understand code that isn't self-explanatory — non-obvious invariants, the reason for a non-obvious approach, tricky edge cases. They must NOT narrate changes.

  • When fixing a bug, lint, or doing a refactor, do not add a comment explaining what was wrong or why you changed it. The corrected code no longer has the issue, so such a comment describes a problem that isn't in the code — it serves no future reader.
  • Rationale for a fix belongs in the commit message and PR description, not in the source.
  • Never answer a reviewer in a code comment. When addressing review feedback, the justification goes in the reply on the review thread; the source gets only what a reader who never saw the review needs. A comment that argues for the new code over what the reviewer objected to is narrating a change — the thing it contrasts against isn't in the file.
  • Write present-tense statements of intent/invariant ("X must be Y because Z"), never history ("changed this from A to B", "without this guard X would happen", "previously this did A").

Key Facts

Token Amounts

  • All amounts in code/manifests are in microtari: 1 TARI = 1,000,000 microtari
  • In manifests, use TARI as the resource identifier (not XTR, which is deprecated)
  • User-facing: use tTARI (testnet) or $TARI (mainnet)

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.
