Solutions

1. Use "true" or "false" (also accepted: 1/0, t/f, T/F, TRUE/FALSE, True/False).
2. Trim whitespace and quotes around the value in config.toml.
3. Convert yes/no style values to true/false before applying.

Example fix

// before
setFunc("yes") // error
// after
setFunc("true")

if _, err := strconv.ParseBool(strings.TrimSpace(v)); err != nil { return fmt.Errorf("invalid boolean: %s", v) }

if err := setThinkingMessages(v); err != nil {
    if strings.Contains(err.Error(), "invalid boolean") { /* re-prompt with true/false */ }
    return err
}

When it happens

Trigger: Setting the thinking-messages option with a value like "yes", "on", "enabled", or "true " (whitespace) that ParseBool rejects.

Common situations: Config file written with YAML-style `yes`/`no` booleans; user typing natural-language booleans in an interactive set command.
