+- Duplicate-message handling may be tightened through profile prompts only.
 - Keep prompt text short enough for small local models to follow.
 - Treat continuation requests such as `proceed` or `continue` as commands to execute the next unfinished step, not as prompts for another status response.
 - Do not include user-specific provider names, API keys, local paths, or secrets.

+When the warning says you sent the same message again, do not resend the same JSON. Change the tool, action, arguments, or final answer so the next message is meaningfully different.
