Greptile SummaryThis PR adds real-time message steering to PraisonAI agents, allowing callers to queue guidance messages that are injected into the agent's LLM prompt between execution turns, with high-priority messages able to interrupt in-progress tool calls.
Confidence Score: 4/5Safe to merge with the understanding that LOW/NORMAL priority steering messages arriving during tool execution will be silently dropped rather than delivered. The steering hook in tool_execution.py calls _check_steering_messages(), which dequeues the message unconditionally. For non-urgent messages the formatted string is returned but never injected into any prompt — the guidance is consumed and lost. execution_mixin.py already ran its pre-chat check before the tool fired, so no subsequent check will pick it up. tool_execution.py — the steering check before each tool call dequeues non-urgent messages without using them.

There was a problem hiding this comment.
process_steering only dequeues a single message per invocation, but _check_steering_messages is called once before each LLM call, so any messages queued after the first one accumulate and are returned to the agent one-per-chat-turn. If users queue several steering messages rapidly during a slow task, all but the oldest remain pending for potentially many turns. Consider draining all queued messages (or at least a bounded batch) in a single call so guidance is not arbitrarily delayed.

In `@src/praisonai-agents/praisonaiagents/agent/execution_mixin.py`:
- Around line 809-816: Wrap the steering check and chat invocation in a
try/except around the call to _check_steering_messages() and the creation of
prompt_with_steering so exceptions are caught and surfaced with context; on
exception set current_status[0] to a clear failure message and set
result_holder[0] to the exception (or raise a RuntimeError from the original)
including remediation hints and any agent/context identifiers, then re-raise to
fail fast. Also fix prompt formatting when creating prompt_with_steering by
trimming input and joining prompt and steering_msg with a clear separator (e.g.,
double newline and a short “Steering Guidance” delimiter) rather than simple
concatenation, and ensure you call self.chat(prompt_with_steering, **kwargs)
only after successful formatting. Include references to the symbols
_check_steering_messages, prompt_with_steering, current_status, result_holder,

semantics but is clamped to the same numeric level as URGENT when enqueued (see
MessageSteering.queue_message and MessagePriority in message_queue.py), so
INTERRUPT doesn't outrank URGENT end-to-end; fix by either
removing/degeneralizing INTERRUPT from SteeringPriority or by updating the
queuing logic to special-case INTERRUPT (e.g., treat SteeringPriority.INTERRUPT
as an immediate interrupt path or map it to a distinct MessagePriority value not
clamped by MessagePriority.URGENT) so that messages created with
SteeringPriority.INTERRUPT truly preempt URGENT messages in
MessageSteering.queue_message and the underlying message_queue handling.
In `@src/praisonai-agents/praisonaiagents/agent/message_steering.py`:
- Around line 165-257: The mixin currently assumes more than
MessageSteeringProtocol guarantees: update either the protocol or the mixin;
preferred fix is to extend MessageSteeringProtocol to include the status/message
surface used here (add enabled: bool, get_pending_messages() -> List[Dict],
has_pending_messages() -> bool, and make process_steering(context: Dict) -> bool
populate context["steering_messages"] with dicts containing "content" and
"priority"), then ensure _init_message_steering accepts MessageSteeringProtocol
implementations that implement those symbols; alternatively (if you cannot
change the protocol) make get_steering_status(), message_steering_enabled and
_check_steering_messages() defensive by using getattr/hasattr and calling only
protocol methods (e.g., a process_steering() return value that directly returns
messages) so the mixin no longer assumes .enabled, .get_pending_messages(),

message if it raises, then inspect the returned steering message's priority
field using the SteeringPriority enum (e.g., compare steering_msg.priority or
steering_msg.get("priority") to SteeringPriority.INTERRUPT) instead of searching
for the substring "INTERRUPT"; if the priority equals INTERRUPT (or equivalent

them.
- Around line 18-88: The test suite is missing a mandatory live agentic test
that actually runs the LLM and verifies steering injection; add a new test
(e.g., test_message_steering_live_execution) that creates an Agent with
message_steering=True and a real LLM (llm="gpt-4o-mini"), starts execution via
Agent.start("Summarize the benefits of async programming") in a background
thread, calls Agent.steer("Keep it under 50 words", priority=HIGH) while the
agent is running, waits for the thread to finish, then assert the returned
response is non-empty and that the steering guidance appears in the response or
in the agent’s prompt/tracing/hook output (use Agent._check_steering_messages or
any tracing hook to validate injection); ensure timing (sleep) and thread join
timeout are used so the steer call occurs during execution and the test cleans
up reliably.

Add error handling and improve prompt formatting for steering integration.
The steering check lacks defensive error handling and could produce malformed prompts:
- If
_check_steering_messages()raises an exception, the entire chat thread fails with no recovery - The f-string concatenation
f"{prompt}{steering_msg}"directly appends steering text without a separator, potentially causing parsing issues for the LLM

INTERRUPT does not actually outrank URGENT end-to-end.
src/praisonai-agents/praisonaiagents/agent/message_queue.py only supports priorities up to URGENT=20, and MessageSteering.queue_message() later clamps the enqueued value with min(priority, MessagePriority.URGENT.value). So an INTERRUPT message is queued with the same priority as URGENT, which means an earlier urgent message can still be processed first. That breaks the stronger interruption semantics exposed by this public enum.

The custom steering backend contract is stricter than MessageSteeringProtocol.
_init_message_steering() accepts any MessageSteeringProtocol, but get_steering_status() / message_steering_enabled read .enabled, and _check_steering_messages() assumes process_steering() mutates context["steering_messages"] with content and priority keys. Neither requirement exists in the published protocol, so a backend that satisfies the public type can still raise AttributeError or silently drop steering during execution. Please either extend the protocol with the status/message surface the mixin needs, or make the mixin depend only on protocol methods.

Use priority-level check instead of string matching for steering interruption.
The current implementation searches for the string "INTERRUPT" in the steering message content, which is fragile and doesn't align with the protocol-driven design. According to the PR objectives and review stack context, SteeringPriority enum exists with priority levels (LOW, NORMAL, HIGH, URGENT, INTERRUPT), and the steering message should contain priority metadata.
Additionally, the check lacks error handling—if _check_steering_messages() raises, tool execution fails entirely.

Move test file to proper test directory.
The test file is located at the repository root instead of within the tests/ subdirectory. According to coding guidelines, tests should be organized into unit/, integration/, e2e/ subdirectories.
Suggested location:
src/praisonai-agents/tests/integration/test_message_steering.py
This change will:
- Follow project conventions for test organization
- Allow test discovery tools to find it automatically
- Separate test code from production code
Based on coding guidelines: organize tests into unit/, integration/, e2e/ subdirectories with fixtures/ for shared test data.

Add mandatory real agentic test with actual LLM execution.
The current tests are smoke tests that only validate object construction and state checks. According to coding guidelines, real agentic tests are MANDATORY for every feature: the agent must call agent.start() with a real prompt, call the LLM, and produce actual text response.
Missing test case:
- Create agent with
message_steering=True - Start execution with
agent.start("Summarize the benefits of async programming") - During execution, call
agent.steer("Keep it under 50 words", priority=HIGH)from a background thread - Verify the agent's response respects the steering guidance
- Validate that steering was actually injected into the prompt via hooks or tracing
Example structure:
def test_message_steering_live_execution():
"""Test steering injection during live LLM execution."""
agent = Agent(
name="steering_test",
instructions="You are a helpful assistant",
message_steering=True,
llm="gpt-4o-mini"
)
# Start execution in background thread
import threading
result_holder = [None]
def run_agent():
result_holder[0] = agent.start("Explain quantum computing")
thread = threading.Thread(target=run_agent)
thread.start()
# Send steering while running
time.sleep(0.5) # Let execution start
msg_id = agent.steer("Be very concise", priority=10)
thread.join(timeout=30)
result = result_holder[0]
# Validate result contains response
assert result, "Should return LLM response"
# Additional assertions based on actual behaviorBased on coding guidelines: Real agentic tests are MANDATORY for every feature—Agent must call agent.start() with a real prompt, call the LLM, and produce actual text response, not just smoke tests of object construction.

In `@test_message_steering.py` around lines 18 - 88, The test suite is missing a
mandatory live agentic test that actually runs the LLM and verifies steering
injection; add a new test (e.g., test_message_steering_live_execution) that
creates an Agent with message_steering=True and a real LLM (llm="gpt-4o-mini"),
starts execution via Agent.start("Summarize the benefits of async programming")
in a background thread, calls Agent.steer("Keep it under 50 words",
priority=HIGH) while the agent is running, waits for the thread to finish, then
assert the returned response is non-empty and that the steering guidance appears
in the response or in the agent’s prompt/tracing/hook output (use
Agent._check_steering_messages or any tracing hook to validate injection);
ensure timing (sleep) and thread join timeout are used so the steer call occurs
during execution and the test cleans up reliably.

_check_steering_messages() calls process_steering(), which dequeues the message before returning. When the returned string does not match [URGENT USER GUIDANCE], execution falls through — the message is consumed and permanently lost. A LOW or NORMAL priority message that arrives while a tool is running will never reach the LLM prompt: it was dequeued here, and execution_mixin.py already ran its own check (before chat() started), so it will not pick it up again. The fix is to skip the steering dequeue entirely for non-interrupt cases in tool_execution.py — let the message remain queued so execution_mixin.py can inject it on the next turn, and only interrupt the tool for genuinely high-priority messages.
