Cairo — StarkNet Smart Contract Reference

What This Skill Does

The Cairo StarkNet Smart Contract Reference skill acts as an intelligent assistant tailored specifically for developers working within the StarkNet ecosystem. It serves as an on-demand technical manual for the Cairo programming language, providing immediate access to language syntax, type definitions, storage patterns, and event management. By streamlining access to the latest StarkNet standards, this skill eliminates the need to constantly switch between your IDE and browser documentation, keeping your development workflow fluid and error-free.

Installation

To install this skill, run the following command in your terminal within the OpenClaw environment:

clawhub install openclaw/skills/skills/bytesagain1/cairo

Once installed, you can trigger the skill by referencing the cairo command structure. Ensure your environment is properly configured to execute the underlying shell scripts provided by the skill repository.

Use Cases

1. Boilerplate Generation: Quickly spin up standard contract frameworks such as ERC-20 tokens or Ownable patterns, saving time on repetitive setup.
2. Debugging Syntax: Use the syntax command to verify control flow patterns or function modifiers when you run into compilation errors.
3. Architecting State: Consult the storage and events modules to ensure your contract state is optimized for the StarkNet architecture and that your indexing logic follows best practices for off-chain observability.
4. Onboarding: Help developers new to Cairo understand complex types like felt252 and custom structs by providing clear, concise examples on demand.

Example Prompts

1. "cairo template erc20 -- please generate a basic implementation with mint and burn functionality."
2. "cairo storage -- explain how to implement a mapping in a Cairo contract and the correct way to read from it."
3. "cairo syntax -- show me the correct way to handle error propagation and panics in a StarkNet smart contract."

Tips & Limitations

• Tip: Always verify the generated templates against the latest Cairo version requirements, as the StarkNet ecosystem evolves rapidly. The template command provides a baseline, not a production-ready audit.
• Tip: When debugging, use the types command to verify your data structures match the expectations of the StarkNet core library.
• Limitation: This skill provides reference material and boilerplate code; it does not perform automated security audits. Always subject your smart contracts to rigorous testing and formal audits before mainnet deployment. Ensure your environment has the necessary bash execution permissions to allow the skill to function as intended.
