• Actions Taken:

    • Changed jail implementation from interactive bash (bash -li) to non-interactive bash (bash -l) in jail/run.sh
    • Applied the fix to both the agent service (port 12001) and monitoring service (port 12002)
    • Added comprehensive tests in jailClient.output-cleaning.test.ts to validate clean output behavior
    • Verified existing output cleaning logic properly handles trimming and EOC marker detection

  • Friction/Success Points:

    • Success: The fix was minimal and surgical - only 2 character changes in the shell script (-li to -l)
    • Success: No changes needed to the output cleaning logic as it was already working correctly
    • Success: All existing tests continue to pass, showing backward compatibility is maintained

  • Lessons Learned:

    • Interactive bash shells produce unwanted prompts and warnings when used programmatically without a TTY
    • Non-interactive login shells (bash -l) provide clean I/O for programmatic control while still loading user environment
    • The existing EOC marker approach combined with substring() and trim() already provided robust output cleaning
    • Comprehensive test coverage helps validate that minimal changes don’t break existing functionality
