49-84:⚠️ Potential issue | 🔴 CriticalThese legacy UI modules still require removed dependencies with incomplete guards.
ui/chat.py,ui/code.py,ui/agents.py,ui/realtime.py, andui/db.pyhave top-level imports ofchainlit,sqlalchemy, andsql_alchemy—all removed from thechat,code, andrealtimeextras in this PR. Thecli/main.pymethods that invoke these files (lines 5186–5300) only guard onCHAINLIT_AVAILABLE, which does not verify the presence ofsqlalchemyorsql_alchemy. If a user installs chainlit separately (or from another project) before runningpraisonai realtime,praisonai chat, etc., the module-level imports will fail with confusingModuleNotFoundError.Either: (a) restore these dependencies to the relevant extras for the deprecation window, or (b) wrap the entire modules in optional imports with clear error messages, or (c) confirm these UI modules are no longer reachable and can be safely deleted.

In `@src/praisonai/praisonai/cli/commands/realtime.py`:
- Line 18: The verbose flag defined in the CLI handler is accepted but never
used; update the command to forward the verbose boolean into the launch path by
setting the PRAISONAI_LOG_LEVEL (or equivalent) before calling _launch_aiui_app
so the child app respects -v/--verbose: if verbose is True set
PRAISONAI_LOG_LEVEL to a verbose value (e.g., "DEBUG" or "INFO") and export it
to the environment, then call _launch_aiui_app with the same behavior, or
alternatively remove the verbose option entirely; ensure you modify the CLI
function that declares verbose and the call site of _launch_aiui_app to either
read the env var or accept an explicit log-level argument so the flag is not a
silent no-op.
In `@src/praisonai/praisonai/cli/commands/ui.py`:
- Line 56: Remove the unnecessary f-string prefix on the print statement that
logs the UI install error: change the print(f"\n\033[91mERROR: PraisonAI UI
(aiui) is not installed.\033[0m") to a plain string print("\n\033[91mERROR:
PraisonAI UI (aiui) is not installed.\033[0m"); this targets the print call
containing "ERROR: PraisonAI UI (aiui) is not installed." (and then re-run the
linter to ensure F541 is resolved).
In `@src/praisonai/praisonai/cli/main.py`:
- Around line 5311-5316: The CLI currently calls _launch_aiui_app with
host="0.0.0.0", which exposes the UI on all interfaces; change the default host
value passed to _launch_aiui_app to "127.0.0.1" so the dashboard binds to
loopback by default (while keeping the existing host parameter so callers can
still explicitly override it), i.e., update the invocation that sets host to
"0.0.0.0" to use "127.0.0.1" instead (refer to the _launch_aiui_app call site in
main.py).
In `@src/praisonai/praisonai/ui_agents/default_app.py`:
- Around line 34-52: yaml.safe_load can return None or non-dict types, so guard
the use of 'agents' by verifying config is a dict before checking 'agents' in
it; in the try block after config = yaml.safe_load(f) add an isinstance(config,
dict) check (and if not, log a clear warning including the actual type/value and
return []), then proceed to iterate config['agents']; reference the
variables/config block around yaml.safe_load and the agents list construction in
default_app.py to locate where to add this guard.
In `@src/praisonai/praisonai/ui_realtime/default_app.py`:
- Around line 49-70: The _realtime_cache currently grows without bounds and uses
the shared fallback key 'default' when aiui.current_session.id is missing,
causing memory leaks and state collisions; update on_message to use a bounded
cache (e.g., an LRU or TTL cache) instead of the plain dict _realtime_cache,
ensure new Agent(...) instances are inserted into that bounded cache, wire an
aiui session-delete/cleanup hook to explicitly evict entries for the session id,
and change the fallback behavior so it either fails closed or generates a unique
per-request id rather than pooling everything under 'default' (refer to symbols:
_realtime_cache, on_message, aiui.current_session, Agent).
In `@src/praisonai/praisonai/ui/_aiui_datastore.py`:
- Around line 44-50: The current list_sessions method returns [] which breaks
dashboard persistence; update it to (1) prefer calling a new protocol method
SessionStoreProtocol.list_sessions (add this method to the praisonaiagents
protocol so stores can implement it) and delegate to it when available,
otherwise (2) fall back to runtime capability-checking: if hasattr(self._store,
"list_sessions") call and return that result for stores like SQLite/Redis/Mongo,
and if neither is available log a one-time warning (use module/class-level flag
or logger.once) indicating sessions cannot be enumerated and return an empty
list; reference the existing methods add_message, get_session and the store
instance self._store when applying this change.
- Around line 11-16: Remove the silent BaseDataStore fallback and ensure an
explicit ImportError is raised when aiui is unavailable: delete the fallback
class in the BaseDataStore import block so the ImportError propagates, or if you
prefer lazy detection mirror praisonaiagents' pattern by keeping an
_AIUI_AVAILABLE flag and adding an explicit check in
PraisonAISessionDataStore.__init__ (or the module-level adapter initializer)
that raises ImportError("praisonaiui is required to use
PraisonAISessionDataStore") when _AIUI_AVAILABLE is False; this will prevent
aiui.set_datastore(PraisonAISessionDataStore()) from later failing with
confusing AttributeError/TypeError.
- Around line 83-90: add_message is async but invokes the synchronous store
method self._store.add_message which can block the event loop; wrap the sync
call with await asyncio.to_thread(self._store.add_message, session_id, role=...,
content=..., metadata=...) or alternatively extend SessionStoreProtocol with an
async add_message_async and call await self._store.add_message_async(...). Also
address create_session which currently only returns a dict without persisting:
either add a create_session(session_id, metadata) hook to SessionStoreProtocol
and call it from create_session, or document the lazy-creation behavior so
callers know they must persist the session before calling get_messages.
In `@src/praisonai/tests/unit/test_aiui_datastore.py`:
- Around line 216-224: The test_import_fallback is a no-op because both the try
and except simply pass; change it to actually verify the fallback by simulating
the missing aiui dependency and asserting BaseDataStore is the module's sentinel
class: use monkeypatch to remove or set sys.modules["praisonaiui.datastore"] to
None (or delete it), reload praisonai.ui._aiui_datastore
(importlib.reload/import_module) and then assert that
mod.BaseDataStore.__module__ == "praisonai.ui._aiui_datastore" (or otherwise
inspect mod.BaseDataStore to confirm it's the fallback sentinel), replacing the
current try/except pass structure in test_import_fallback.

--verbose/-v is now a silent no-op.
After routing to _launch_aiui_app, the verbose parameter is accepted but never read or forwarded. Users passing -v will get no additional output and no error, which is surprising. Either wire it through to _launch_aiui_app (e.g., set a PRAISONAI_LOG_LEVEL env var before launching) or drop the option to avoid misleading users.

Guard against yaml.safe_load returning non-dict.
yaml.safe_load returns None for an empty agents.yaml and can return a list if the file starts with a top‑level sequence. In both cases 'agents' in config raises TypeError, which the blanket except Exception then reports as a generic "Failed to load agents.yaml" warning — masking the real shape‑mismatch bug.

Unbounded per-session agent cache + shared 'default' fallback.
_realtime_cache grows for every distinct session id and is never evicted — in a long‑running UI process this is a memory leak (Agent instances retain conversation state, tools, and LLM client handles). Additionally, when aiui.current_session is missing or lacks id, every such caller collides on the same 'default' key, so unrelated users share the same Agent instance and its in‑memory state.
Consider bounding the cache (e.g., functools.lru_cache-style LRU or cachetools.TTLCache), wiring an aiui session‑delete hook to evict the entry, and either failing closed or minting a per‑request id instead of pooling under 'default'. The same issue applies in ui_bot/default_app.py (_bots_cache) and ui_agents/default_app.py (_agents_cache).

Silent BaseDataStore fallback will mask missing aiui dependency.
When praisonaiui is not installed, BaseDataStore degrades to an empty object-like class. PraisonAISessionDataStore then appears to construct fine, but the subsequent aiui.set_datastore(PraisonAISessionDataStore()) call in claw/default_app.py, ui_chat/default_app.py, etc., will fail later with a more confusing AttributeError or TypeError (it won't be recognized as a BaseDataStore subclass by aiui). Since every caller in this PR also imports praisonaiui as aiui at module top, the fallback never actually helps — it only hides the real error.
Either drop the fallback and let the ImportError propagate, or raise an explicit ImportError in __init__ as you already do for praisonaiagents:

list_sessions() hard-coded to [] defeats the "native persistence for dashboard sessions" goal.
The aiui dashboard's Sessions page calls list_sessions() to render history. Returning [] unconditionally means users will never see persisted sessions in the UI, even though add_message / get_session do persist them via the underlying store — which directly contradicts a headline feature in the PR description ("native persistence for dashboard sessions").
If SessionStoreProtocol really has no list capability, please at minimum:
- Add a
list_sessions()method (or equivalent) to the protocol in praisonaiagents so this can be implemented properly — this is the correct home per the protocol-driven core learning. - Or, for stores that support enumeration (e.g. SQLite/Redis/Mongo), type-check and delegate (
if hasattr(self._store, "list_sessions"): …). - Log a one-time warning so the empty Sessions page is not silently misleading.

add_message is async but calls sync store methods.
self._store.add_message(...) is invoked synchronously inside an async def. If the underlying store performs I/O (file/Redis/Mongo), this blocks the event loop. Use await asyncio.to_thread(self._store.add_message, …) when the store is sync, or extend SessionStoreProtocol with async variants (add_message_async, etc.) if available.
Additionally, create_session() only constructs a dict and returns — nothing is written to the store. Since SessionStoreProtocol lacks a create_session hook, stores requiring explicit session creation will not persist the session on the wrapper's create_session() call. Calling get_messages() immediately after would return empty results. Document this lazy-creation invariant or add an explicit creation hook to SessionStoreProtocol.

test_import_fallback is a no‑op — both branches pass unconditionally.
As written, this test asserts nothing: if the import succeeds it passes silently, and if it raises ImportError the except also passes. It cannot fail regardless of the fallback behavior it claims to validate.
Either assert on the actual fallback contract (e.g., patch the praisonaiui.datastore import at the module level and verify BaseDataStore resolves to the sentinel class BaseDataStore: pass defined in _aiui_datastore.py) or remove the test.
