What
The runner keeps a group of command-line flags it treats together, including sdk-url, resume, mcp-config and settings. That group now also holds:
system-prompt-fileappend-system-prompt-fileappend-subagent-system-prompt-fileagents
Why
These flags are now handled the same way as the flags already in that group.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
