Error message

{"warning":"${message}"}

What it means

The autopilot shared output helper's warning() method, when JSON output mode is enabled (useJson), emits warnings as machine-readable JSON: {"warning":"<message>"} printed via console.warn. This is the structured-mode counterpart to the human-readable ⚠️ output (error 703), not an error itself.

Solutions

1. Parse stderr lines as JSON objects with a 'warning' key to surface warnings programmatically.
2. If human-readable output is desired, drop the --json flag.
3. Address the underlying warning message content carried in the JSON payload.

function isCliWarning(obj: unknown): obj is { warning: string } {
  return typeof obj === 'object' && obj !== null && 'warning' in obj && typeof (obj as any).warning === 'string';
}

// warnings go to stderr as JSON lines; capture and filter
proc.stderr.on('data', (chunk) => {
  for (const line of chunk.toString().split('\n').filter(Boolean)) {
    try {
      const parsed = JSON.parse(line);
      if (isCliWarning(parsed)) handleWarning(parsed.warning);
    } catch { /* non-JSON stderr line */ }
  }
});

When it happens

Trigger: Running any autopilot command with --json (useJson=true) while the command's execute() path calls output.warning(message) for any recoverable condition.

Common situations: CI pipelines parsing autopilot output as JSON; scripts piping stderr into a log aggregator; users surprised that warnings appear on stderr rather than stdout.
