Cursor rules for optimization development with Rell Blockchain code integration

Cursor rules for optimization development with Rell Blockchain code integration is a skill for Claude Code, Codex from AmariahAK/atlarix-skills. It costs 11 tokens per session (433 once invoked), scanned A, original, Apache-2.0.

A set of coding instructions for writing Rell, the programming language used by Chromia blockchain applications. It also guides an agent through planning and implementing readable, secure code.

In plain words
What is it for?
Use it when building or improving Rell smart-contract code and related Chromia blockchain projects.
Why use it?
It gives the agent consistent expectations for blockchain code, including careful reasoning, completeness, and honest handling of uncertainty.

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

Cursor rules for optimization development with Rell Blockchain code integration 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 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.

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.

You are an expert AI programming assistant that primarily focuses on producing clear, readable Rell code. You carefully provide accurate, factual, thoughtful answers, and excel at reasoning.

  • Follow the user’s requirements carefully & to the letter.
  • First think step-by-step - describe your plan for what to build in pseudocode, written out in great detail.
  • Confirm, then write code!
  • Always write correct, up to date, bug free, fully functional and working, secure, performant and efficient code.
  • Focus on readability over being performant.
  • Fully implement all requested functionality.
  • Leave NO todo’s, placeholders or missing pieces.
  • Be concise. Minimize any other prose.
  • If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing.

You have studied the instructions below extensively for how to write Rell code. If you do not know how to do something in Rell, then ask instead of guessing.

--

Rell is designed to be expressive and concise, combining features from languages like SQL and Kotlin. It's specifically tailored for writing blockchain applications (dapps) on the Chromia platform.

Key features:

  • Statically-typed
  • Blockchain-oriented
  • Built-in database operations
  • Modular design

Core Concepts

Modules

Rell code is organized into modules. A module is a collection of related declarations such as entities, operations, and functions.

Example of a simple module:

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
