Greptile SummaryThis PR implements an in-flight run control system for channel sessions, introducing
Confidence Score: 3/5The change is additive and does not break existing chat flows, but the two central behaviors it advertises — run control during active agent turns and the /stop command — are both completely inactive in the Telegram adapter as shipped. The Telegram message handler never calls src/praisonai/praisonai/bots/telegram.py needs a /stop CommandHandler registration and must route non-streaming messages through chat_with_run_control() instead of chat().

@claude You are the FINAL architecture reviewer. If the branch is under MervinPraison/PraisonAI (not a fork), you are able to make modifications to this branch and push directly. SCOPE: Focus ONLY on Python packages (praisonaiagents, praisonai). Do NOT modify praisonai-rust or praisonai-ts. Read ALL comments above from Gemini, Qodo, CodeRabbit, and Copilot carefully before responding. Phase 1: Review per AGENTS.md
Phase 2: FIX Valid Issues Phase 3: Final Verdict |

Claude finished @MervinPraison's task —— View job I'm conducting a final architecture review of this PR as requested. Review Tasks
Architecture Compliance Assessment ✅Per AGENTS.md, this implementation follows protocol-driven design correctly:
Critical Fixes RequiredFix 1: Interrupt Controller Restoration BugFile: # ❌ Current broken code:
if original_interrupt is not None:
agent._interrupt_controller = original_interrupt
else:
delattr(agent, '_interrupt_controller') # BREAKS after first run
# ✅ Fixed code:
if original_interrupt is not None:
agent._interrupt_controller = original_interrupt
else:
agent._interrupt_controller = None # Restore None, don't delete attributeImpact: After the first run, Fix 2: Memory Leak in CleanupFile: # ❌ Current broken code:
if session.start_time and (now - session.start_time) > max_age_seconds:
# ✅ Fixed code:
# Check both active runs AND completed sessions
if session.start_time: # Active run
if (now - session.start_time) > max_age_seconds:
stale_users.append(user_id)
else: # Completed session - use run_generation as age indicator
# Clean up sessions that haven't had activity recently
# We need to track last activity time for completed sessions
pass # This needs a more comprehensive fixBetter Fix: Add class SessionRunState:
def __init__(self):
self.is_running = False
self.run_generation = 0
self.pending_message: Optional[str] = None
self.interrupt_controller: Optional["InterruptController"] = None
self.start_time: Optional[float] = None
self.last_activity: float = time.time() # NEW: Always track activity
# In cleanup_stale_sessions:
if (now - session.last_activity) > max_age_seconds:
stale_users.append(user_id)Fix 3: Config Field WiringFiles: Bot constructors need to read BotConfig and create SessionRunControl The # In TelegramBot.__init__ (and other bot classes):
self._session: BotSessionManager = BotSessionManager(
store=_store,
platform="telegram",
# ADD THIS:
run_control=self._create_run_control() if self.config.busy_mode != "queue" else None
)
def _create_run_control(self):
"""Create run control if configured."""
from ._run_control import SessionRunControl
return SessionRunControl(
busy_mode=self.config.busy_mode,
busy_ack_template=self.config.busy_ack
)Fix 4: Steer Mode Warning LevelFile: # ❌ Current code uses DEBUG level:
logger.debug(f"Steer mode not fully implemented, falling back to queue")
# ✅ Should be WARNING level:
logger.warning("Steer mode is not yet implemented, falling back to queue mode")Final Verdict: ❌ BLOCKING ISSUES - REQUIRES CHANGESWhile the architecture and approach are sound, 3 critical bugs make this PR not ready for merge:
RecommendationDO NOT MERGE until these fixes are applied. The core feature works but these bugs will cause silent failures in production. Action Required
The feature implementation is architecturally sound and follows AGENTS.md correctly, but the execution bugs must be fixed first. Note: I don't have push permissions to this fork, so these fixes need to be applied by someone with write access to the branch. |

@claude resolve merge conflict Before fixing: run an in-depth analysis using multi-agents to understand overlap with recent merges on main (#1849, #1896, #1908, bot PRs #1918–#1922, #1919 cancellation, durable inbound #1923, etc.) and whether this PR is still needed or should be closed.
