Greptile SummaryThis PR addresses three architectural gaps in the wrapper layer: separating sync/async SQLite stores, replacing manual framework dispatch with a unified
Confidence Score: 3/5Not safe to merge until the deadlock and invalid-SQL bugs in SyncSQLiteConversationStore are fixed. The new SyncSQLiteConversationStore has two distinct, confirmed defects on its core write/read paths. First, any write method called before explicit store.init() will hang permanently: the method acquires self._lock (a non-reentrant threading.Lock), calls _get_connection, which then calls init(), which tries to acquire the same lock on the same thread. Second, passing offset without limit to list_sessions or get_messages generates ORDER BY … OFFSET ? SQL that SQLite rejects with a syntax error. The rest of the PR — the unified integration registry, the adapter-based AutoGen resolution, and the observability hooks — is architecturally sound and appears correct. src/praisonai/praisonai/persistence/conversation/sync_sqlite.py requires fixes before merging.

15-20:⚠️ Potential issue | 🔴 Critical | ⚡ Quick winAsyncSQLiteConversationStore remains abstract because it doesn’t implement ConversationStore’s required sync methods
ConversationStoredefines abstract sync methods (create_session,get_session,update_session,delete_session,list_sessions,add_message,get_messages,delete_messages,close), butAsyncSQLiteConversationStoreonly implementsasync_*equivalents (andasync_close) without providing the required sync method overrides.- Since the registry’s
async_sqlitefactory instantiatesAsyncSQLiteConversationStore, this will trigger abstract-method instantiation errors.- Fix by adding sync stubs that raise clear “async-only” errors (or by switching to an async-specific base/protocol).

Inline comments:
In `@src/praisonai/praisonai/agents_generator.py`:
- Around line 647-660: After resolving the adapter, call the centralized
validator assert_framework_available(adapter.name) immediately before invoking
init_observability(...) and adapter.setup(...); specifically, move the
assert_framework_available(adapter.name) call to just after adapter resolution
(and before init_observability and adapter.setup) so framework availability is
guaranteed prior to running init_observability and adapter.setup.
In `@src/praisonai/praisonai/integrations/_unified_registry.py`:
- Around line 118-147: The registrations are storing loader callables (e.g.,
_claude_code, _managed_agent, _local_managed_agent, _anthropic_managed_agent,
_managed_config, _local_managed_config, _sandboxed_agent,
_sandboxed_agent_config, _hosted_agent, _hosted_agent_config, _local_agent,
_local_agent_config, etc.) so __getattr__ / get_by_attr returns the loader
instead of the actual symbol; to fix, change those self.register(...) calls to
pass the result of invoking the loader (e.g., use _claude_code(),
_managed_agent(), _local_managed_agent(), etc.) so the registry stores the
actual ClaudeCodeIntegration/ManagedAgent/etc. objects rather than their factory
functions, keeping function-like exports (actual callables meant to be exported)
unchanged.
In `@src/praisonai/praisonai/persistence/conversation/sync_sqlite.py`:
- Around line 248-257: The synchronous store method signatures must match the
ConversationStore protocol: change add_message(self, message) to
add_message(self, session_id, message) and update its implementation
(referencing add_message) to use the provided session_id when inserting into the
messages table; similarly change get_messages(self, session_id, *, before=None,
after=None, limit=...) (replace the current offset-based signature) and update
its query construction (referencing get_messages) to filter on session_id and
optional before/after timestamps rather than offset, preserving existing return
types and locking/connection handling so other polymorphic callers continue to
work.
- Around line 223-224: The pagination SQL generation in list_sessions and
get_messages can produce "ORDER BY ... OFFSET ?" which SQLite rejects when LIMIT
is omitted; change the logic that builds limit_clause and offset_clause so that
if offset is provided but limit is None you emit " LIMIT ?" with a value of -1
(to act as unbounded) followed by " OFFSET ?" and add -1 into the bound
parameters before the offset value; otherwise keep the existing "LIMIT ?"
behavior when limit is provided and only add " OFFSET ?" when offset is
provided; ensure the parameter ordering in the calls that build params for
list_sessions and get_messages (the same functions named list_sessions and
get_messages) is updated so the -1 is inserted immediately before the offset
parameter when used.
- Around line 56-58: SQLite connections created in init (where conn =
sqlite3.connect(self.path)) and in _get_connection must enable foreign key
enforcement so the ON DELETE CASCADE in _create_tables (messages.session_id)
actually works; after each sqlite3.connect(...) call (both in init and
_get_connection) execute the PRAGMA "foreign_keys = ON" on that connection (and
ensure the command runs before any operations/returns) so delete_session will
cascade and avoid orphaned messages.
- Line 24: SyncSQLiteConversationStore is missing the required abstract method
close(self) -> None from ConversationStore, so add a concrete close(self) ->
None implementation on SyncSQLiteConversationStore that cleanly closes its
SQLite resources (e.g., call self._conn.close() or self._connection.close() and
set the attribute to None), make it idempotent (no-op if already closed), and
ensure any related cleanup used by clear_session is handled; implement this
method inside the SyncSQLiteConversationStore class so the class is no longer
abstract and can be instantiated.
In `@src/praisonai/praisonai/persistence/factory.py`:
- Around line 52-60: The current backend selection logic silently accepts
unknown mode values and falls back to using backend as-is; update the logic
around mode/backend_name (the branches that set backend_name based on mode ==
"sync", mode == "async", and mode == "auto") to explicitly validate mode against
the allowed set ("sync","async","auto") and raise a ValueError (or similar) when
mode is invalid, including the invalid mode value in the error message; apply
the same validation and error behavior to the other identical branch later in
the file where backend_name is computed so typos no longer silently disable
sync/async routing.
In `@src/praisonai/praisonai/persistence/registry.py`:
- Around line 124-127: The helper _sync_sqlite currently calls
SyncSQLiteConversationStore(path=url or path, **kwargs) which can pass path=None
and override the class default; change _sync_sqlite to compute the resolved_path
= url or path and only include the path argument in the call when resolved_path
is truthy (e.g., build call_kwargs = dict(kwargs); if resolved_path is not None:
call_kwargs["path"]=resolved_path) and then return
SyncSQLiteConversationStore(**call_kwargs) so the constructor default is
preserved when no path/url is provided.

Validate resolved framework availability before init_observability() and adapter.setup().
adapter.setup() can execute framework-specific initialization before assert_framework_available(...) runs, which can produce less actionable errors than the centralized validator. Move the availability assertion immediately after resolve.

Built-ins are being registered as loader factories, so exports resolve to the wrong object type.
self.register(...) currently stores _claude_code, _managed_agent, etc. directly. Because __getattr__ returns get_by_attr(...) as-is, consumers receive loader functions instead of ClaudeCodeIntegration/ManagedAgent symbols, which breaks attribute imports and instantiation paths.
Suggested minimal correctness fix
- self.register("ClaudeCodeIntegration", _claude_code)
+ self.register("ClaudeCodeIntegration", _claude_code())Apply the same pattern to all registrations that currently pass loader callables.

Add close() to SyncSQLiteConversationStore to satisfy ConversationStore
ConversationStore declares close(self) -> None as an @abstractmethod, but SyncSQLiteConversationStore defines no close() method (the class ends after clear_session), so the store remains an abstract class and will fail to instantiate.

SyncSQLiteConversationStore is missing the required abstract method close(self)
-> None from ConversationStore, so add a concrete close(self) -> None
implementation on SyncSQLiteConversationStore that cleanly closes its SQLite
resources (e.g., call self._conn.close() or self._connection.close() and set the
attribute to None), make it idempotent (no-op if already closed), and ensure any
related cleanup used by clear_session is handled; implement this method inside
the SyncSQLiteConversationStore class so the class is no longer abstract and can
be instantiated.

Enable SQLite foreign-key enforcement for every connection (PRAGMA foreign_keys = ON).
_create_tables() defines ON DELETE CASCADE on messages.session_id, but the SQLite connections created in init() (~56) and _get_connection() (~107) don’t enable PRAGMA foreign_keys = ON, so cascades won’t fire and delete_session() can leave orphan messages rows.

56 - 58, SQLite connections created in init (where conn =
sqlite3.connect(self.path)) and in _get_connection must enable foreign key
enforcement so the ON DELETE CASCADE in _create_tables (messages.session_id)
actually works; after each sqlite3.connect(...) call (both in init and
_get_connection) execute the PRAGMA "foreign_keys = ON" on that connection (and
ensure the command runs before any operations/returns) so delete_session will
cascade and avoid orphaned messages.

Fix SQLite pagination when offset is set without limit.
In src/praisonai/praisonai/persistence/conversation/sync_sqlite.py (list_sessions lines ~223-224 and get_messages ~282-283), the query can end up as ... ORDER BY <col> DESC OFFSET ? when limit is None, which SQLite rejects. Keep bound params, but when offset is not None and limit is None, emit LIMIT ? with -1 before adding the OFFSET ?.

223 - 224, The pagination SQL generation in list_sessions and get_messages can
produce "ORDER BY ... OFFSET ?" which SQLite rejects when LIMIT is omitted;
change the logic that builds limit_clause and offset_clause so that if offset is
provided but limit is None you emit " LIMIT ?" with a value of -1 (to act as
unbounded) followed by " OFFSET ?" and add -1 into the bound parameters before
the offset value; otherwise keep the existing "LIMIT ?" behavior when limit is
provided and only add " OFFSET ?" when offset is provided; ensure the parameter
ordering in the calls that build params for list_sessions and get_messages (the
same functions named list_sessions and get_messages) is updated so the -1 is
inserted immediately before the offset parameter when used.

Keep method signatures protocol-compatible with ConversationStore.
Line 248 defines add_message(self, message) and Line 272 defines get_messages(..., offset=...); this diverges from the sync store contract used elsewhere (add_message(session_id, message) and get_messages(..., before, after)), risking polymorphic call breakage.

248 - 257, The synchronous store method signatures must match the
ConversationStore protocol: change add_message(self, message) to
add_message(self, session_id, message) and update its implementation
(referencing add_message) to use the provided session_id when inserting into the
messages table; similarly change get_messages(self, session_id, *, before=None,
after=None, limit=...) (replace the current offset-based signature) and update
its query construction (referencing get_messages) to filter on session_id and
optional before/after timestamps rather than offset, preserving existing return
types and locking/connection handling so other polymorphic callers continue to
work.

Reject invalid mode values instead of silently falling back.
Lines 59–60 treat unknown modes as normal backend selection, so typos in config (Line 131) can silently disable intended sync/async routing.

init()
threading.Lock is not reentrant, but every write method (create_session, update_session, delete_session, add_message, delete_messages) holds self._lock and then calls _get_connection. _get_connection contains the defensive check if not self._initialized: self.init(), and init tries to acquire self._lock a second time on the same thread — causing a permanent deadlock. Any caller who omits the explicit store.init() and then performs a write will hang indefinitely.
