Cadence

Claude Code Skills

Install Flow's official Claude Code plugin for expert-level Cadence and Flow knowledge — the full Cadence + Flow skill suite in one install.

Flow ships an official Claude Code plugin marketplace at onflow/flow-ai-tools. The flow-dev plugin bundles the full Cadence + Flow skill suite — covering language fundamentals, NFT/FT token development, smart-contract auditing, code scaffolding, testing, the Flow React SDK, project setup, the Flow CLI, the dev environment, DeFi architecture, and tokenomics.

Install

In Claude Code:

/plugin marketplace add onflow/flow-ai-tools
/plugin install flow-dev@flow-ai-tools
/reload-plugins

The /reload-plugins step refreshes the active session so the new skills register without a restart.

Or use the one-line installer that also installs the Flow CLI and configures the Cadence MCP server:

sh -ci "$(curl -fsSL https://raw.githubusercontent.com/onflow/flow-ai-tools/main/scripts/install.sh)"
