Inverts the architecture so Claude Code runs natively on the host (enabling clipboard/Alt+V image paste) while shell commands are proxied to the Docker container via CLAUDE_CODE_SHELL_PREFIX. - Add generate_proxy_script() for command proxying via docker exec - Modify launch() to use npx @anthropic-ai/claude-code on host - Remove Claude Code CLI from Dockerfile (runs on host now) - Add npx preflight check - Rewrite README for v2 architecture Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The proxy script's sed commands used | as a delimiter, but the patterns contain || (bash OR) and >| (force-overwrite), which broke sed parsing. Switch to # as the delimiter. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Piping commands via `printf | docker exec -i bash` produced no output on Windows/Docker Desktop. Switch to `bash -c "$CMD"` which passes the command as an argument instead of via stdin. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Node.js on Windows can't spawn bash scripts directly — it needs a .cmd wrapper. Generate proxy.cmd alongside the bash proxy script and use its Windows path as CLAUDE_CODE_SHELL_PREFIX. Also adds debug logging to /tmp/claude-box-proxy.log for diagnosing proxy issues. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Debug log revealed the real command format from Claude Code:
- No -c flag — command passed as positional args directly
- Preamble uses { shopt ... || setopt ... } not just shopt
- Paths use /c/Users/... format, not /tmp/...
- Includes \< /dev/null for stdin isolation
- CWD tracking path is not single-quoted
Updated proxy to handle all these correctly. Also strip the
\< /dev/null stdin redirect since Docker provides its own stdin.

The sed $ anchor wasn't working correctly, causing the pwd tracking to duplicate instead of replace. Switch to removing the entire suffix and appending a clean replacement. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Upgrade git to 2.48+ via ppa:git-core/ppa (for worktree.useRelativePaths) - Set worktree.useRelativePaths=true in entrypoint.sh so .git files in worktrees use relative paths (work on both host and container) - Document worktree support in README Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
