Autonomous V2 System - Fixes Applied

Date: November 23, 2025
Status: All fixes completed including critical spam prevention ✅

---

🚨 CRITICAL Production Fixes (Added After Testing)

0a. Channel Filtering - SPAM PREVENTION ✅

File: bot/utils/autonomous.py

Issue: Bot was processing messages from ALL channels, not just the autonomous channel. This caused:

• Reactions to messages in wrong channels
• Privacy concerns (tracking all messages)
• Wasted processing

Fix: Added server config check to only process messages from the configured autonomous channel:

# Get server config to check if this is the autonomous channel
server_config = server_manager.get_server_config(guild_id)
if not server_config:
    return  # No config for this server

# CRITICAL: Only process messages from the autonomous channel
if message.channel.id != server_config.autonomous_channel_id:
    return  # Ignore messages from other channels

Impact:

• ✅ Only tracks messages from autonomous channel
• ✅ Won't react to messages in other channels
• ✅ Privacy protection

---

0b. Startup Cooldown - SPAM PREVENTION ✅

File: bot/utils/autonomous_engine.py

Issue: On bot startup, Miku immediately sent 3 messages back-to-back within 6 seconds. This happened because the engine saw message history and immediately triggered actions.

Fix: Added 2-minute startup cooldown:

# STARTUP COOLDOWN: Don't act for first 2 minutes after bot startup
time_since_startup = time.time() - self.bot_startup_time
if time_since_startup < 120:  # 2 minutes
    return None

Impact:

• ✅ Prevents spam on bot restart
• ✅ Gives context time to build naturally
• ✅ Much better user experience

---

0c. Rate Limiting - SPAM PREVENTION ✅

File: bot/utils/autonomous.py

Issue: Even with decision logic, multiple rapid messages could trigger multiple actions in quick succession.

Fix: Added hard rate limit of 30 seconds minimum between ANY autonomous actions:

_MIN_ACTION_INTERVAL = 30  # Minimum 30 seconds between actions

# Check if we're within rate limit
if time_since_last < _MIN_ACTION_INTERVAL:
    return  # Too soon, skip

Impact:

• ✅ Prevents rapid-fire messages
• ✅ Extra safety net beyond engine cooldowns
• ✅ Natural conversation pacing

---

🐛 Critical Fixes (Original)

1. Presence Update Event Handler ✅

File: bot/bot.py

Issue: Comment was misleading about what parameters are being passed.

Fix: Updated comment to accurately describe that Discord.py passes before/after Member objects with different states.

Impact: No functional change, but clarifies the implementation for future maintainers.

---

2. Activity Tracking with Debug Logging ✅

File: bot/utils/autonomous.py

Issue: No debug output to verify presence tracking was working.

Fix: Added detailed logging for status changes and activity starts:

print(f"👤 [V2] {member.display_name} status changed: {before.status} → {after.status}")
print(f"🎮 [V2] {member.display_name} started activity: {activity_name}")

Impact: Easier to verify that presence tracking is functioning correctly.

---

3. Decay Factor Calculation ✅

File: bot/utils/autonomous_engine.py

Issue: Decay factor was 0.95 instead of the correct value for 1-hour half-life with 15-minute intervals.

Before: decay_factor = 0.95 (gives ~81.5% after 1 hour, not 50%)

After: decay_factor = 0.5 ** (1/4) ≈ 0.841 (gives exactly 50% after 1 hour)

Impact: Events now decay at the correct rate as documented.

---

⚠️ Important Fixes

4. Activity Timestamps and Expiration ✅

File: bot/utils/autonomous_engine.py

Issue: Activities were stored without timestamps and never expired.

Before: users_started_activity: List[str]

After: users_started_activity: List[tuple] with (activity_name, timestamp) tuples

New Method: _clean_old_activities() removes activities older than 1 hour

Impact:

• Activities automatically expire after 1 hour
• More accurate tracking of current user activities
• Prevents engaging users about activities they stopped hours ago

---

5. Activity Deduplication ✅

File: bot/utils/autonomous_engine.py

Issue: Same activity could be tracked multiple times if user stopped and restarted.

Fix: Before adding an activity, remove any existing entries with the same name:

ctx.users_started_activity = [
    (name, ts) for name, ts in ctx.users_started_activity 
    if name != activity_name
]

Impact: Each unique activity appears only once in the tracking list.

---

6. Cap messages_since_last_appearance ✅

File: bot/utils/autonomous_engine.py

Issue: Counter could grow indefinitely during long sleep periods, causing inappropriate FOMO triggers.

Fix: Cap the counter at 100 messages:

if ctx.messages_since_last_appearance > 100:
    ctx.messages_since_last_appearance = 100

Impact: Prevents Miku from immediately feeling massive FOMO after waking up from sleep mode.

---

✨ Nice-to-Have Improvements

7. Defensive Dictionary Iteration ✅

File: bot/utils/autonomous.py

Issue: Iterating over server_manager.servers directly could fail if dict changes during iteration.

Fix: Create a copy of keys before iterating:

guild_ids = list(server_manager.servers.keys())
for guild_id in guild_ids:
    # Safe iteration

Impact: Prevents potential runtime errors if servers are added/removed during decay task.

---

8. Periodic Decay Task Monitoring ✅

File: bot/utils/autonomous.py

Issue: No way to verify the decay task was running or how many times it executed.

Fix: Added comprehensive logging:

iteration_count += 1
uptime_hours = (time.time() - task_start_time) / 3600
print(f"🧹 [V2] Decay task completed (iteration #{iteration_count}, uptime: {uptime_hours:.1f}h)")
print(f"   └─ Processed {len(guild_ids)} servers")

Impact: Easy to verify the task is running and monitor its health.

---

9. Comprehensive Debug Logging ✅

Files:

• bot/utils/autonomous_engine.py
• bot/utils/autonomous.py
• bot/globals.py

Issue: No way to understand why the engine made specific decisions.

Fix: Added optional debug mode with detailed logging:

New Environment Variable: AUTONOMOUS_DEBUG=true (default: false)

Debug Output Example:

🔍 [V2 Debug] Decision Check for Guild 123456
   Mood: bubbly (energy=0.90, sociability=0.95, impulsiveness=0.80)
   Momentum: 0.75
   Messages (5min/1hr): 15/42
   Messages since appearance: 8
   Time since last action: 450s
   Active activities: 2
   
   [Join Conv] momentum=0.75 > 0.63? True
   [Join Conv] messages=8 >= 5? True
   [Join Conv] cooldown=450s > 300s? True
   [Join Conv] impulsive roll? True | Result: True
   
✅ [V2 Debug] DECISION: join_conversation

Impact:

• Easy to debug decision logic
• Understand why actions are/aren't taken
• Tune thresholds based on real behavior
• No performance impact when disabled (default)

---

📊 Error Handling Improvements

Added Try-Catch Blocks

File: bot/utils/autonomous.py

In periodic_decay_task():

• Wraps decay_events() call for each guild
• Wraps save_context() call
• Prevents one server's error from breaking the entire task

Impact: Decay task is more resilient to individual server errors.

To adjust, edit bot/utils/autonomous_engine.py line ~238:

if time_since_startup < 120:  # Change to desired seconds

Rate Limit (NEW)

Default: 30 seconds minimum between actions

To adjust, edit bot/utils/autonomous.py line ~15:

_MIN_ACTION_INTERVAL = 30  # Change to desired seconds

Debug Mode (Optional)
