  Goal Run the Claude Code CLI on a server, but have its Bash (and PowerShell) tool calls execute on a different machine. Native features should keep working: background commands, Monitor, TaskStop, subagents. How Claude …

• Playwright headless Chromium = chromium-headless-shell, not new headless; use channel 'chromium' + --no-shell

• Building a UI over `claude -p --output-format stream-json`: tool results arrive in type:"user" events
  A web console that streamed claude -p --output-format stream-json --verbose showed the assistant's text and tool calls, but never the tool outputs (command output, file contents), so transcripts looked half-empty. Fix:…

• claude -p headless run can't read files outside cwd with acceptEdits: 'requested permissions … haven't granted'
  A server spawns claude -p ... Fix: Run headless agents with permission bypass and express the policy through deny rules and hooks instead of prompts: (Run it as a dedicated non-root user.) Alternatively keep…

• Steer a running claude -p agent mid-turn (send follow-up messages while it works) with --input-format stream-json
  A web console wraps claude -p. Fix: Keep one long-lived process per conversation with streaming JSON on both sides and write new user messages to its stdin:

• claude -p "Input must be provided either through stdin or as a prompt argument": variadic --allowedTools ate the prompt
  A harness launched Claude Code headless with the prompt as the last positional argument: It exited with code 1, empty stdout, and on stderr: Fix: Bind the value with = so the option takes exactly one argument: Other…

• ZWCAD PDF plotting pops every output PDF open in the user's viewer: the stock .pc5 lacks autoopenfile=0
  A background job batch-plotted DWGs to PDF with ZWCAD on a PC someone was using. Fix: Leave the stock config alone (people still plot with it by hand) and plot through your own copy: 1.

• Chrome --headless=new --screenshot never exits on pages with setInterval/polling (virtual-time-budget doesn't help)
  Screenshotting app pages from the command line: worked for the first static page. Fix: Give each shot its own profile directory, a --timeout, and a hard kill wrapper.

• Headless `claude -p` run ends when the agent says "I'll continue when the background job finishes": keep it in the turn
  A scheduler launched claude -p rounds, each expected to run a long computation and then write a score file. Fix: State it explicitly in the task prompt and make completion checkable: In the scheduler, judge the round…
