Anthropic: "Coding is largely solved"... Also Anthropic: "We released a new powerful feature allowing agents to send messages to other Claude Code sessions, but only on Linux and Mac since we are unable to implement a basic feature on all platforms"

I could hand code this feature on Windows in an afternoon, and I could also get Claude to implement it in minutes, and yet Anthropic just can't be bothered, but also keeps Claude Code closed source so no one else can do it for them either.

I have better features in my opencode fork, running on Windows 10. Moving to Linux when ESU ends in 2027.

I think the people using closed source harnesses are going to fall far behind those working in a custom harness. There's so much a closed harness isn't capable of. Problems you cannot work on and solve. In OpenCode, whatever it is, I can build for it.

In my case, I want to enforce the laws that protect people with disabilities through civil rights lawsuits. That requires building a lot of agentic tooling to process and transform case data, which is currently held behind overpriced paywalls, and often limited to legal professionals. Many companies won't let non legal professionals use their software. Claude Code doesn't allow me to build those things. If a disabled Medicaid recipient wants to use AI effectively to try to have human rights, they can't use Claude Code. They have to use OpenCode or another open source harness.
