This task is specific to per-agent UI conventions and log readability.

Acceptance Criteria

• Shell commands render as plain text without bash -lc wrappers.
• Role labels and message content appear on the same line, separated by a space.
• Command-result annotations show a checkmark and duration for zero exit codes, or exit code: N and duration for nonzero codes, in the format <icon or exit code> <duration>ms.
• Existing functionality remains unaffected beyond formatting changes.
• Verbose background event logs (e.g. sandbox‑denied exec errors, retries) collapse into a single command execution entry showing command start, running indicator, and concise completion status.
• Automated examples or tests verify the new rendering behavior.

Implementation

This change will touch both the event-processing and rendering layers of the Rust TUI:

• Event processing (codex-rs/exec/src/event_processor.rs):

  • Strip any bash -lc wrapper when formatting shell commands via escape_command.
  • Replace verbose BackgroundEvent logs for sandbox-denied errors and automatic retries with a unified exec-command begin/end sequence.
  • Annotate completed commands with either a checkmark (✅) and <duration>ms for success or exit code: N <duration>ms for failures.

• TUI rendering (codex-rs/tui/src/history_cell.rs):

  • Collapse consecutive BackgroundEvent entries related to exec failures/retries into the standard active/completed exec-command cells.
  • Update new_active_exec_command and new_completed_exec_command to use the new inline format (icon or exit code + duration, with $ <command> on the same block).
  • Ensure role labels and plain-text messages render on a single line separated by a space.

• Tests (codex-rs/tui/tests/):

  • Add or update test fixtures to verify:
    • Commands appear without any bash -lc boilerplate.
    • Completed commands show the correct checkmark or exit-code annotation with accurate duration formatting.
    • Background debugging events no longer leak raw debug strings and are correctly collapsed into the exec-command flow.

Notes

• Improves readability of interactive sessions and logs by reducing boilerplate.
• Ensure compatibility with both live TUI output and persisted log transcripts.
