avail by hairyf/blockchain-master

Skill based on Avail Node (availproject/avail), generated from sources/avail. Doc path: sources/avail/README.md, sources/avail/client/basic-authorship/README.md, sources/avail/e2e/README.md, and node/rpc/runtime source (cli, command, kate-rpc, apis).

Avail is a data-availability layer. The Avail Node is the official Substrate-based client. It supports multiple chains (dev, turing, mainnet), Kate RPC for DA queries (rows, proofs, block length, per-tx data proof), and optional custom block authoring via the basic-authorship client. Use this skill to run nodes, script Kate RPC, integrate with light clients or explorers, and reason about runtime APIs.
