Inline comments:
In `@src/praisonai-agents/praisonaiagents/agent/agent.py`:
- Around line 3238-3250: The sync entrypoint run_autonomous() currently ignores
interrupt_controller so add the same cooperative-cancellation guard used in
run_autonomous_async(): before invoking self.chat(prompt) check if
self.interrupt_controller and self.interrupt_controller.is_set(), capture reason
= self.interrupt_controller.reason or "unknown", and return an AutonomyResult
with success=False, output like f"Task interrupted: {reason}",
completion_reason="interrupted", and preserve iterations, stage, actions_taken,
duration_seconds (time_module.time() - start_time) and started_at so the sync
loop mirrors the async behavior.
- Line 554: Ruff flags undefined names InterruptController and MemoryManager in
the signature; update the static types by adding InterruptController to the
TYPE_CHECKING imports (so it’s available only for typing) and replace the
MemoryManager union/type with typing.Any (and import Any if not present) in the
function/class where interrupt_controller: Optional['InterruptController'] =
None and any parameters/attributes typed as MemoryManager; this removes the
unresolved MemoryManager symbol and ensures InterruptController is recognized
for static analysis.

In `@src/praisonai-agents/praisonaiagents/agent/interrupt.py`:
- Around line 43-45: The request() method currently overwrites the existing
interrupt reason; modify it so the first reason is preserved by only setting
self._reason if it is not already set (do this inside the existing with
self._lock block to keep thread-safety), then still call self._flag.set() to
signal the interrupt; update the code that assigns self._reason in request()
(refer to method request and attributes _reason, _flag, _lock) to guard
assignment so subsequent calls do not clobber the original reason.
- Around line 15-16: Add a lightweight typing.Protocol for the interrupt
extension point (e.g., name it InterruptControllerProtocol) in the same module
and import Protocol from typing; define the protocol with the same public method
signatures used by Agent and the existing class (match methods declared on
InterruptController), then have the concrete InterruptController class formally
implement/extend that protocol so Agent can accept the protocol type as its
pluggable cancellation surface. Ensure the protocol is exported/available for
type hints (and update any Agent type annotations to use
InterruptControllerProtocol where appropriate).

In `@src/praisonai-agents/praisonaiagents/llm/llm.py`:
- Around line 653-685: The new G5 error classifier
(_classify_error_and_should_retry) must be invoked from the sync and async retry
wrappers (e.g., the retry_with_backoff_sync / retry_with_backoff_async code
paths referenced near lines 711-720 and 772-780) so classifier decisions drive
retry behavior instead of the legacy-only logic; update those wrappers to call
self._classify_error_and_should_retry(error) on each failure, honor the returned
(category, should_retry, retry_delay) to decide whether to retry, and use the
returned retry_delay instead of legacy parsing. Also remove the hard-coded
attempt=1 in get_retry_delay: make _classify_error_and_should_retry accept and
forward the current attempt count (or pass attempt into get_retry_delay) so
category-specific backoff scales with the retry attempt, and ensure
rate-limit-specific extract_retry_after still takes precedence when present.

In `@src/praisonai-agents/praisonaiagents/llm/sanitize.py`:
- Around line 47-110: The sanitize_messages function currently only sanitizes
top-level message fields, the content list items' "text", and direct string
fields, but it must recursively sanitize any nested dict/list string values
(e.g., tool_calls[].function.arguments or other provider-specific nested
strings). Update sanitize_messages to walk each message value recursively (for
dicts and lists) and call strip_surrogates on every string encountered, updating
the structure in-place and setting changed = True when any replacement occurs;
keep the existing special-casing for content but delegate deep traversal to the
new recursive sanitizer helper (e.g., sanitize_value or similar) that handles
dicts, lists, and strings and is invoked for message["content"], other message
fields, and nested items.
- Around line 38-44: The current surrogate-stripping logic in the try block
encodes text with 'utf-16'/'surrogatepass' then decodes using 'replace', which
leaves lone surrogates as U+FFFD; change the decode call to use 'ignore' so lone
surrogates are dropped entirely (i.e., replace decode(..., 'replace') with
decode(..., 'ignore')) so inputs like "User\uD801Name" become "UserName"; update
the try/except block around the encode/decode sequence that operates on the
variable text accordingly.

In `@src/praisonai-agents/praisonaiagents/session/hierarchy.py`:
- Around line 493-529: The auto-title routine currently calls the sync
self._load_extended_session on the event loop, awaits generate_title_async, then
writes back with self._save_extended_session which can clobber concurrent
updates; change to non-blocking I/O and a reload-before-save pattern: use an
async I/O variant (or run the sync I/O in a thread executor) instead of calling
self._load_extended_session directly on the event loop, await
generate_title_async(user_msg, assistant_msg) as before, then re-load the latest
session state from disk (e.g., an async _load_extended_session_async or via
run_in_executor) and only write back using an async _save_extended_session_async
(or run_in_executor) if the reloaded session still has an empty/title-less
session.title (trimmed) to avoid overwriting concurrent updates; also ensure all
disk I/O is off the event loop and use the same unique symbols seen here
(self._load_extended_session / generate_title_async /
self._save_extended_session / session.title) when locating and updating the
code.
- Around line 508-516: The code treats SessionMessage objects like dicts (using
msg.get) and performs blocking file I/O inside the async auto_title() while also
swallowing exceptions; fix by replacing msg.get("role")/msg.get("content") with
attribute access via getattr(msg, "role", None) or isinstance checks
(SessionMessage) in the loop that extracts user_msg/assistant_msg, and move
_load_extended_session()/_save_extended_session() file operations off the event
loop (either implement async file I/O or call the existing sync functions via
asyncio.to_thread/run_in_executor) inside auto_title(); also remove the silent
except block and log/raise the caught exception with context so failures are
visible.

In `@src/praisonai-agents/praisonaiagents/tools/call_executor.py`:
- Around line 141-150: The current ImportError try/except swallows
missing-module errors and also masks implementation errors; change it to first
import has_write_conflicts (catch only ImportError from the import), and if the
import fails immediately fall back to sequential execution using
SequentialToolCallExecutor().execute_batch(tool_calls, execute_tool_fn) while
logging a clear message via logger; if import succeeds, call
has_write_conflicts(tool_calls) outside the import try and, if it returns True,
log the conflict and return the sequential_executor.execute_batch(...) as
before. Ensure only ImportError is caught for the import and do not wrap the
has_write_conflicts(...) call in that try so implementation errors surface.

In `@src/praisonai-agents/praisonaiagents/tools/path_overlap.py`:
- Around line 15-44: extract_paths currently only runs for tools whose
function_name is in _WRITE_TOOLS, letting custom write tools bypass conflict
checks; update extract_paths (or the code path that calls it) to also treat a
ToolCall as a potential writer when either ToolCall has explicit
side-effect/write metadata (e.g., a boolean like ToolCall.mutates_files or
ToolCall.has_side_effects) or when the call contains any argument name from
_PATH_ARG_NAMES (e.g., check tool_call.arguments.keys() ∩ _PATH_ARG_NAMES) and
then extract/resolve those paths; keep explicit _WRITE_TOOLS as preferred but
fall back to path-hint detection and prioritize honoring any new ToolCall
metadata flag if present (reference extract_paths, _WRITE_TOOLS,
_PATH_ARG_NAMES, and ToolCall).
- Around line 49-53: The loop that collects path-like args (iterating
args.items() and checking _PATH_ARG_NAMES) currently calls
pathlib.Path(arg_value).resolve() even for empty strings which resolve to CWD;
change the condition so empty or whitespace-only strings are skipped before
resolving (e.g., ensure arg_value is a non-empty string via something like
isinstance(arg_value, str) and arg_value.strip() != ""), then only call
pathlib.Path(arg_value).resolve() and append to paths; update the block around
the for loop that references _PATH_ARG_NAMES, pathlib.Path(...).resolve(), and
paths to implement this guard.

In `@src/praisonai-agents/tests/unit/llm/test_error_classifier.py`:
- Around line 115-147: The tests expect get_retry_delay to use factor ** attempt
(not factor ** (attempt - 1)), so update the implementation of get_retry_delay
in error_classifier.py to compute delays as base_delay * (factor ** attempt) for
the RATE_LIMIT and TRANSIENT categories (keeping existing factors, caps and
base_delay parameter), and update the get_retry_delay docstring examples to
match the new formula; ensure no other off-by-one logic remains (references:
get_retry_delay function and ErrorCategory enum names).

In `@src/praisonai-agents/tests/unit/llm/test_sanitize.py`:
- Around line 47-157: Add an end-to-end integration test that verifies malformed
Unicode is sanitized before an actual LLM request: create a new test that
instantiates your Agent (use the same Agent class used elsewhere), call
agent.start() with a prompt containing a lone surrogate (e.g., "\uD800") and
assert the call completes without provider encoding errors and returns a text
response; ensure the test exercises the sanitize_messages/sanitize_text path by
sending a messages payload (not just constructing objects) and verifying the
returned response is a string and the agent did not raise encoding/serialization
exceptions when contacting the real LLM provider configured for tests.

In `@src/praisonai-agents/tests/unit/session/test_title_gen.py`:
- Around line 40-68: Current unit tests only exercise fallback paths for
generate_title and generate_title_async and do not run a real agentic flow; add
an integration/e2e test that constructs an Agent (use the real Agent class),
calls agent.start("A clear prompt for title generation") so the LLM is actually
invoked, waits for the session to complete, then assert that the session title
(e.g., session.title or agent.session.title) is a non-empty string and derived
from the first exchange (contains keywords from the prompt/assistant response);
ensure the test uses the real LLM-backed flow (not mocking generate_title),
cleans up the agent/session after run, and mirrors async behavior if needed (use
pytest.mark.asyncio for async start).

Minor comments:
In `@src/praisonai-agents/praisonaiagents/llm/error_classifier.py`:
- Line 12: The module's public API list __all__ is missing the documented/tested
helpers extract_retry_after and get_error_context, causing import-* and IDE
tooling to be inaccurate; update the __all__ declaration (which currently lists
"ErrorCategory", "classify_error", "should_retry", "get_retry_delay") to also
include "extract_retry_after" and "get_error_context" so those symbols are
exported.
- Around line 187-203: The extract_retry_after logic over-matches because the
last regex r"(\d+).*second" is too loose; tighten the patterns in the patterns
list used by extract_retry_after to require proximity and units (e.g. use a
pattern like (\d+)\s*seconds?\b for seconds) and add word boundaries to the
other patterns (e.g. \bretry[:\s]+(\d+)\b, \bwait[:\s]+(\d+)\b) so stray numbers
like "HTTP 500 error at second attempt" are not captured; update the patterns
list in extract_retry_after and add a unit-specific negative test case such as
"HTTP 500 error at second attempt" (expect None) plus a positive case like
"retry after 5 seconds" to lock behavior.

In `@src/praisonai-agents/praisonaiagents/session/hierarchy.py`:
- Around line 531-533: Replace the silent "except Exception: pass" in the
title-generation block with a debug log that preserves the non-critical
fallback: catch the exception and call the module/logger's debug method (e.g.,
logger.debug or processLogger.debug) including the exception details
(exc_info=True or str(err)) and the session context by including session_id (use
the existing session_id variable or self.session_id), then continue to return
the fallback title as before.

In `@src/praisonai-agents/praisonaiagents/session/title.py`:
- Around line 108-120: Replace the silent "pass" handlers in the title
generation flow by using the module logger (e.g., logger =
logging.getLogger(__name__)) and emitting messages with context and exception
details: in the asyncio.TimeoutError handler inside the title generation
function/method log a warning/debug with exc_info=False and a remediation hint
(e.g., "title generation timed out; consider increasing timeout or using a
smaller model"); in the inner except Exception (LLM-specific) log logger.warning
or logger.debug with exc_info=True and include the model/config name from that
scope; for the ImportError handler log logger.error with exc_info=True and a
remediation hint to install/enable the required LLM module; and for the outer
except Exception use logger.exception to capture unexpected failures (and keep
the fallback title logic intact); ensure all logs include unique context
(function name or model identifier) to aid interception/hooks.

In `@src/praisonai-agents/tests/unit/agent/test_interrupt.py`:
- Around line 51-80: The test_thread_safety uses sleep-based coordination which
is flaky; change it to use threading.Event to deterministically synchronize the
worker and checker. Specifically, in the test_thread_safety for
InterruptController replace the sleep/wait loops in the nested worker and
checker functions with two threading.Event instances (e.g., start_event and
done_event) so the worker waits on start_event before calling
controller.request("thread_cancel") and then sets done_event, while the checker
waits on the same events (or controller.is_set combined with a wait on
done_event) to observe the interrupt; update the assertions to rely on the
events-driven ordering instead of timing and keep the results list and thread
joins as before.
- Around line 108-127: Replace the flaky microbenchmark in
test_zero_overhead_when_not_used: remove the time.perf_counter loops and the "<
1ms" assertions and instead perform a deterministic functional check that
creating an InterruptController and calling controller.is_set() returns the
expected default (e.g., False) and does not raise; reference the test function
name test_zero_overhead_when_not_used and the InterruptController and is_set()
symbols when locating the code to change.

In `@src/praisonai-agents/tests/unit/tools/test_path_overlap.py`:
- Around line 20-262: Replace hard-coded "/tmp/..." literals in the tests with
pytest's tmp_path (or a shared synthetic Path) so Ruff S108 is avoided: update
calls to ToolCall and direct pathlib.Path uses in tests referencing "/tmp/..."
to use tmp_path / "name" (or str(tmp_path / "name") where a string is expected),
add the tmp_path fixture as a parameter to any test method that builds paths,
and update tests that construct pathlib.Path("/tmp/...") (e.g., in
TestPathConflicts methods using paths_conflict) to use tmp_path / "..." or
tmp_path.joinpath(...); look for usages around extract_paths,
detect_path_conflicts, group_by_conflicts, has_write_conflicts, and
paths_conflict to make consistent replacements.

Nitpick comments:
In `@src/praisonai-agents/praisonaiagents/llm/error_classifier.py`:
- Around line 26-90: The current _ERROR_PATTERNS mapping and matching order
causes less-specific RATE_LIMIT and TRANSIENT regexes to preempt CONTEXT_LIMIT
or AUTH matches; update the classifier so specificity wins by either reordering
_ERROR_PATTERNS to: ErrorCategory.CONTEXT_LIMIT, ErrorCategory.AUTH,
ErrorCategory.INVALID_REQUEST, ErrorCategory.RATE_LIMIT,
ErrorCategory.TRANSIENT, or change the matching logic in the classification
function (e.g., classify_error) to evaluate all patterns, score/category-rank
matches, and return the highest-priority category (use ErrorCategory as the
priority reference) instead of returning on first regex hit.

In `@src/praisonai-agents/praisonaiagents/session/title.py`:
- Around line 146-147: The current truncation logic uses clean_msg.split('.')
which breaks decimals, ellipses, abbreviations and URLs; replace that with a
regex-based split that only treats a period as a sentence terminator when
followed by whitespace or end-of-string (e.g. use re.split with a pattern like
r'\.(?:\s|$)' and take the first element) so the variable clean_msg is truncated
only at real sentence-ending periods while preserving numeric decimals, domain
names, and other internal dots.

In `@src/praisonai-agents/tests/unit/llm/test_error_classifier.py`:
- Around line 228-260: The test's backward-compatibility block in
TestBackwardCompatibility.test_rate_limit_backward_compat silently skips on any
ImportError/AttributeError; replace the broad try/except with a
pytest.importorskip('praisonaiagents.llm.llm') at the top of the block and then
instantiate LLM and use getattr(llm, '_is_rate_limit_error', None) to check
presence—if the method is None call pytest.skip with a clear reason; keep the
assertions comparing llm._is_rate_limit_error(error) and classify_error(error)
== ErrorCategory.RATE_LIMIT when present so the check either runs or is
explicitly skipped with a message.
