OpenCode as a FOSS/local alternative to Claude Code

[TomLucidor]

Currently, Claude Code is subscription-based, and workarounds like Claude Code Router + ZCF seems to eat up RAM in weird ways. And people are popularizing OpenCode, which uses OpenAI-compatible API tooling, and runs pretty fast with SLMs. Could this app be made to support other CLI tooling?

So this uses the Claude Agent SDK (the typescript version), which is actually just a wrapper around the Claude Code CLI that communicates via a stdin/stdout JSOn protocol. As a result, this style of app isn't affected by the recent 3rd party Claude Max subscription crack down.

@Roasbeef and the workarounds are still kinda painful to deal with (Claude Code Router is abusing RAM for some reason, not sure about alternative routers that can use OpenAI-compatibles). If skills/subagents are compatible across coding agents, that would be a relief. Rules and MCP configs are convertible, but subagents are a new field https://github.com/intellectronica/ruler?tab=readme-ov-file#supported-ai-agents
