• High-Level Request:

    • The resolve-python-dependency gauntlet test was failing because it expected completely empty stdout (stdout === "") but flake.nix shellHook output "✅ DOCKER_HOST automatically set to Colima's socket." polluted the stdout.

  • Actions Taken:

    • Applied stdout cleaning logic: Modified the resolve-python-dependency successCondition to clean flake.nix shellHook pollution using the same regex pattern already used in cleanStdoutForJSON:
      • Added: const cleanStdout = stdout.replace(/^.*✅.*$/gm, '').trim();
      • Changed comparison from stdout === "" to cleanStdout === ""
    • Added comprehensive test coverage: Created test cases to verify the cleaning logic works for empty stdout scenarios
    • Validated fix: All 143 tests pass, confirming no regressions introduced

  • Lessons Learned:

    • Reusing existing cleaning patterns reduces complexity and maintains consistency
    • The flake.nix shellHook output can pollute stdout in any command that uses nix develop, so similar issues may occur in other gauntlet tests
    • Minimal surgical fixes that leverage existing code are preferable to creating new cleaning functions
