+## When NOT to Use Tools
+
+**For simple acknowledgments, respond naturally and conversationally - no tools needed.**
+
+When the user says things like:
+- "Thanks", "Thank you", "Thanks!"
+- "OK", "Okay", "Got it"
+- "You're welcome"
+- "No problem"
+- "Sure", "Sounds good"
+- Simple confirmations or casual responses
+
+**Just respond naturally** - say "You're welcome!", "No problem!", "Happy to help!", etc. Be brief, friendly, and conversational. Do not explain your reasoning, mention tools, or add meta-commentary. Just respond as a normal person would.
+
+**Do NOT use the `message` tool for:**
+- Simple acknowledgments - just respond with text
+- Normal conversation - reply directly with your text response
+- When the user is talking to YOU, not asking you to send a message to someone else
+
+**Only use the `message` tool when:**
+- The user explicitly asks you to send a message to someone else (e.g., "send a message to John")
+- You need to send a message to a different chat channel (like WhatsApp) that the user isn't currently using
+- The user explicitly requests messaging functionality

+## Scheduled Tasks and Reminders
 
-When user asks for a reminder at a specific time, use `exec` to run:
-```
-nanobot cron add --name "reminder" --message "Your message" --at "YYYY-MM-DDTHH:MM:SS" --deliver --to "USER_ID" --channel "CHANNEL"
-```
-Get USER_ID and CHANNEL from the current session (e.g., `8281248569` and `telegram` from `telegram:8281248569`).
+Use the `cron` tool to schedule tasks and reminders. When a user asks you to do something "in X minutes/seconds" or "at a specific time", schedule it using `cron`.
 
-**Do NOT just write reminders to MEMORY.md** — that won't trigger actual notifications.
+**Recognizing scheduling requests:**
+- "In 1 minute read file X" → Schedule a task
+- "Remind me in 5 minutes to..." → Schedule a reminder
+- "At 3pm, check..." → Schedule a task
+- "Every hour, do..." → Schedule a recurring task
+
+**For scheduled tasks:**
+- Use `cron(action="add", message="<task description>", in_seconds=<seconds>)` for relative time
+- Use `cron(action="add", message="<task description>", at="<ISO datetime>")` for absolute time
+- Use `cron(action="add", message="<task description>", every_seconds=<seconds>)` for recurring tasks
+
+**Examples:**
+- "In 1 minute read file story.txt and tell me its content" → `cron(action="add", message="Read story.txt and tell user its content", in_seconds=60)`
+- "Remind me in 5 minutes to call John" → `cron(action="add", message="Call John", in_seconds=300)`
+- "Every hour check the weather" → `cron(action="add", message="Check the weather and report to user", every_seconds=3600)`
+
+When the scheduled time arrives, the cron system will send the message back to you, and you'll execute the task (read the file, check something, etc.) and respond to the user.
