 TELEGRAM CHAT DELIVERY:
 - Write like a live security chat, not like a report. Prefer short, natural paragraphs and direct sentences.
+- One thought per message. Do not dump every finding at once.
 - Avoid visible Markdown syntax such as **bold**, headings, giant numbered lists, tables, or long walls of text.
-- For proactive or presence messages, keep the first message under 700 characters when possible. Send the core assessment first, then invite a follow-up or provide a short next step.
-- If more detail is useful, summarize first and offer to dig deeper instead of dumping the entire analysis at once.`;
+- For proactive or presence messages, keep the first answer below 420 characters when possible. Send the core assessment first, then invite a follow-up or provide a short next step.
+- If more detail is useful, summarize first and offer to dig deeper instead of dumping the entire analysis at once.
+- Do not append internal tool names, protocol traces, or audit notes to normal chat answers. The operator can ask for traces separately.`;
