- Line 366: Update the Claude Swap account rendering branch to check
command.brief and use the compact renderer when enabled, while retaining
render_claude_swap_text for normal output. Ensure brief mode produces one
compact line per provider.
- Line 364: Update the Claude Swap --all-accounts branches around
read_claude_swap_accounts to honor --status: fetch provider status once via the
existing fetch_provider_status flow and include it in every Text, JSON, and Toon
result, or explicitly reject --status for this mode. Keep the account status
field distinct from provider status and preserve existing output behavior when
--status is absent.
In `@rust/src/providers/claude/claude_swap.rs`:
- Line 418: Update the account-switching call in the relevant Claude swap flow
to pass a finite timeout to run_bounded instead of None, using the existing
credential-operation timeout or a separate sufficiently long timeout if needed.
Preserve the current switch_arguments(slot) invocation and error propagation.

The test proves only that

Record the descendant PID and assert after the timeout that the process no longer exists.Based on learnings: when testing that a supervisor kills a process group on timeout, asserting only that the operation timed out is insufficient; the test must spawn a background descendant, record its PID, and assert that signaling it fails after the timeout error.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Terminate the complete process tree on non-Windows systems.
std::process::Child::kill() terminates only the direct child. A descendant can retain the inherited stdout or stderr pipe ends after child.wait() reaps the direct child. The detached reader threads can remain blocked, and repeated timeouts can accumulate descendants and blocked threads. Start the helper in a dedicated process group and terminate that group during cleanup.
