We've been working on this for a while actually. Hear you on standards and OSS, it's something we discuss often within the team. There's lots of tradeoffs. We support some standards (eg. MCP, Skills); other standards don't make as much sense for us currently (eg. plugins, agents, hooks, and http://CLAUDE.md -- we want to optimize for the ability to evolve+extend these quickly). I personally have ~100 open source projects, and people on the team have worked a lot on open source (Adam worked on ReactJS and GraphQL, Fiona founded TypeScript and VSCode, Jarred built Bun, I created Undux, etc.). I originally wanted to make Claude Code OSS, and we decided not to open source (for now) in order to move faster. Once Claude Code's feature set is fairly locked in, I think we'd be open to changing this. That said, many components of Claude Code are already open source today: - Bun, which is committed to stay open source - Agent sandbox (https://github.com/anthropic-experimental/sandbox-runtime) - Plugins (https://github.com/anthropics/claude-plugins-official) - Devcontainers (https://github.com/anthropics/claude-code/tree/main/.devcontainer) We feel strongly that it's important to support the OSS community, and hope to do even more in the future.
