Using AI

AI training data about starknet.js is often outdated. To give your AI coding agent accurate, up-to-date guidance, install the official starknet.js skill (skills/starknet-js/). It works with Claude Code, Codex, Cursor, Gemini CLI, and any other agent supporting the open Agent Skills standard.

npx skills add starknet-io/starknet.js

or copy the skill files directly:

mkdir -p ~/.claude/skills/starknet-js && curl -s --output-dir ~/.claude/skills/starknet-js --remote-name-all "https://raw.githubusercontent.com/starknet-io/starknet.js/develop/skills/starknet-js/{SKILL.md,calldata.md,interacting.md}"

This command installs into Claude Code's skills folder — adapt the target directory for other agents.
