Code Review
This pull request refactors the knowledge and memory systems into a protocol-driven architecture using an adapter registry and factory functions. This change decouples core components from heavy dependencies like ChromaDB and MongoDB, enabling lazy loading and improved maintainability. Feedback suggests using native ChromaDB update methods for atomicity, implementing SQLite FTS5 for efficient searching, and avoiding blocking network calls during MongoDB initialization. Furthermore, it is recommended to replace the deprecated datetime.utcnow() and optimize the dual-write logic in the refactored Memory class to reduce I/O overhead.

The update method is implemented by deleting the existing record and then adding a new one. This is not an atomic operation and can lead to data loss if the add call fails (e.g., due to an embedding error or network issue). ChromaDB provides a native update or upsert method that should be used instead to ensure data integrity.

Using LIKE with wildcards (%query%) for searching in SQLite triggers a full table scan. This will result in significant performance degradation as the knowledge base grows. For a knowledge retrieval system, it is highly recommended to use SQLite's FTS5 (Full Text Search) extension, which provides much faster indexing and search capabilities.

Performing a network operation like ping() inside the constructor can block the initialization of the application and lead to failures if the MongoDB server is temporarily unreachable. It is generally better to defer connection validation to the first actual operation or use a dedicated health check mechanism.

datetime.utcnow() is deprecated since Python 3.12. It is recommended to use datetime.now(datetime.timezone.utc) to obtain a timezone-aware UTC datetime object.

This implementation performs a dual-write to both the primary memory_adapter and the legacy _sqlite_adapter. This effectively doubles the I/O overhead for every store operation, which will impact performance. If backward compatibility is required, consider making this behavior configurable or offloading the legacy write to a background thread.

1. Core defines chromaknowledgeadapter 📎 Requirement gap ⚙ Maintainability
A concrete ChromaDB-based knowledge adapter and direct heavy dependency imports (chromadb, markitdown) are added under the core package. This violates the requirement that heavy backend implementations must be moved to a wrapper/integration layer, not shipped within core.
Agent Prompt
## Issue description
Heavy knowledge backend code (ChromaDB + MarkItDown) was added inside the core package. Compliance requires moving heavy backend implementations to a wrapper/integration layer and keeping core lightweight.
## Issue Context
Core should not contain heavy backend implementations/imports; wrappers should implement and register adapters.

AddResult from knowledge.models does not have an error field (it defines id, success, message, metadata). Returning AddResult(success=False, error=...) will raise TypeError at runtime; use the existing message field (or update the model if an error field is required).

AddResult doesn't accept an error kwarg (see knowledge.models.AddResult). This except path will currently raise TypeError and mask the real failure; populate message instead (or extend the model).

Returning str(id(text)) is not a stable/persistent identifier (it’s process-specific and can be reused), so it doesn’t reliably satisfy the MemoryProtocol contract of returning an identifier for stored content. Prefer generating a real ID (e.g., UUID/time-based) and/or adjust the wrapped legacy Memory implementation to return the actual storage ID.

This docstring states the approach “eliminates” hardcoded imports in knowledge.py, but this PR does not actually refactor knowledge/knowledge.py (it still imports markitdown/chromadb at runtime). Consider rewording this as a future-state demo, or update the PR to include the core refactor so the claim matches reality.

This module claims it “eliminates” the hardcoded _check_* functions/imports in memory.py, but this PR doesn’t refactor memory/memory.py (the _check_* functions and self.use_* flags are still present). Consider rewording as a demonstration/future state, or include the core refactor in this PR so the statement is accurate.

In `@src/praisonai-agents/praisonaiagents/knowledge/adapters/__init__.py`:
- Around line 27-40: Remove the heavy backend wiring from the package init: keep
the import and registration of create_sqlite_knowledge_adapter and
register_knowledge_factory("sqlite", create_sqlite_knowledge_adapter) only, and
delete the imports and register_knowledge_factory calls for
create_mem0_knowledge_adapter, create_mongodb_knowledge_adapter, and
create_chroma_knowledge_adapter so those backends are not compiled into the
core; ensure register_knowledge_factory remains exported (so wrapper packages
can import it) and update any __all__ or module exports to reflect the removed
symbols so wrapper packages can import register_knowledge_factory and perform
their own registrations.
In `@src/praisonai-agents/praisonaiagents/knowledge/adapters/factories.py`:
- Around line 64-67: The factory in factories.py returns a
MongoDBKnowledgeAdapter that doesn't implement the KnowledgeStoreProtocol
surface: MongoDBKnowledgeAdapter (and its add/search) lacks get, get_all,
update, delete_all and returns wrong types (str / List[dict]) instead of
AddResult / SearchResult; update the MongoDBKnowledgeAdapter implementation to
implement all required methods (get, get_all, update, delete_all) with correct
signatures and return types conforming to KnowledgeStoreProtocol, and adjust add
and search to return AddResult and SearchResult respectively (or
wrap/adapter-return values to those types) before returning the instance from
the factory.
- Around line 137-178: The search() implementation ignores
user_id/agent_id/run_id and the filters parameter, so update search() (the
method that calls self.collection.query) to build and pass a Chroma-compatible
"where" filter: construct a dict that includes user_id, agent_id and run_id only
when they are not None (matching the keys used by add()), merge/override with
the provided filters dict (filters param) and pass that as the where/filters
argument to self.collection.query; ensure you handle empty values by omitting
those keys and keep the existing behavior of returning an empty SearchResult
when embedding fails. Use the unique symbols search, self.collection.query,
query_embedding, and filters to locate and modify the code.
- Around line 311-327: delete_all has three problems: it accesses
all_items.items but get_all returns a SearchResult with .results, it only
deletes the first page (limit=100) so scoped deletes miss remaining items, and
the unscoped branch calls self.client.delete_collection(self.collection.name)
but does not recreate self.collection leaving the adapter unusable. Fix by
reading ids from SearchResult.results (e.g., iterate each result list) and
implement pagination (loop calling get_all with increasing offset or until no
results) to collect and delete all ids in batches via
self.collection.delete(ids=...), and in the unscoped branch after calling
self.client.delete_collection(...), recreate or reassign self.collection (e.g.,
via the same factory/initialization code used elsewhere) so the adapter remains
usable after deleting the entire collection.
- Around line 38-41: The factory is forwarding registry-only kwargs (like
verbose and db_path) into Mem0Adapter causing a TypeError; in the adapter
creation code that imports and returns Mem0Adapter(**kwargs) replace that with
building a sanitized kwargs dict containing only the parameters
Mem0Adapter.__init__ accepts (e.g., 'config' and 'disable_telemetry') — do not
pass through 'verbose', 'db_path' or other extras coming from
ProtocolDrivenKnowledge._get_adapter_config(); filter or pop the unwanted keys
before calling Mem0Adapter or explicitly construct the argument mapping to pass
only supported keys.
- Around line 90-99: The current factory eagerly imports MarkItDown alongside
chromadb which forces an unrelated dependency even though ChromaKnowledgeAdapter
never uses self.markitdown; update the factory that constructs
ChromaKnowledgeAdapter to only require/import chromadb and defer
importing/instantiating MarkItDown (or pass markitdown=None) so plain-text
Chroma usage works without markitdown installed, and if file parsing is later
needed, lazily import MarkItDown inside the code path that performs parsing (or
inside ChromaKnowledgeAdapter where markitdown is actually used) rather than at
adapter creation.
In `@src/praisonai-agents/praisonaiagents/memory/adapters/__init__.py`:
- Around line 29-42: Remove the hardcoded heavy-backend imports and factory
registrations from this module: do not import create_mem0_memory_adapter,
create_chroma_memory_adapter, or create_mongodb_memory_adapter and remove the
corresponding register_memory_factory("mem0"...),
register_memory_factory("chroma"...), register_memory_factory("mongodb"... )
calls; keep only core adapter registrations such as
register_memory_adapter("sqlite", SqliteMemoryAdapter) and
register_memory_adapter("in_memory", InMemoryAdapter) and ensure the module
exposes the registration API (register_memory_factory/register_memory_adapter)
so wrapper packages can call register_memory_factory(create_...) from their own
initialization code to lazily register mem0/chroma/mongodb implementations.
In `@src/praisonai-agents/praisonaiagents/memory/adapters/factories.py`:
- Around line 111-122: The initializer is only reading mem0_config["config"] so
top-level keys passed by Memory._get_adapter_config/get_memory_adapter are
ignored; update the __init__ (the constructor using parameter mem0_config) to
normalize the incoming config: if mem0_config has a "config" dict use that,
otherwise treat mem0_config itself as the config dict, then read api_key,
org_id, project_id, graph_store/connection_string/database from that normalized
config; apply the same normalization to the other adapter initializer referenced
around lines 318-321 so both adapters correctly honor flat and nested config
shapes.
In `@src/praisonai-agents/praisonaiagents/memory/adapters/legacy_adapter.py`:
- Around line 39-51: The store_short_term and store_long_term methods currently
return Python object ids (id(text)) which are not stable; modify both methods to
capture and return a durable identifier from the legacy backend (call
self._memory.store_short_term(...) and self._memory.store_long_term(...) and use
the backend's returned ID if present), and if the legacy backend does not return
an ID, generate and return a stable UUID (uuid.uuid4()) instead of id(text);
ensure the chosen ID is the one returned to callers so it can be used later to
reference the persisted record.
In `@src/praisonai-agents/praisonaiagents/memory/memory_refactored.py`:
- Line 203: The current logger.info call in memory_refactored.py that prints
f"Storing in short-term memory via {self.provider}: {text[:100]}..." must be
changed to avoid logging memory contents at INFO level; update the logging in
the method where logger.info is used (and the similar call around line 266) to
instead log only non-sensitive metadata such as the provider (self.provider),
the stored text length (len(text)), and any memory identifier (e.g., memory_id
or return value from the storage function), or downgrade to DEBUG if you must
include a redacted preview; remove or redact any actual text/prompt content to
prevent PII/secrets leakage.
- Around line 473-479: The search method currently drops agent_id and run_id and
only routes by user_id; update search(self, ...) to route and forward scoping
parameters: if user_id -> call search_user_memory(user_id, query, ...), elif
agent_id -> call search_agent_memory(agent_id, query, ...), elif run_id -> call
search_run_memory(run_id, query, ...), otherwise call search_long_term(query,
...) and ensure whichever call you make forwards limit, rerank and **kwargs (or
include agent_id/run_id in kwargs) so the adapter receives the scoping
parameters; reference the existing search, search_user_memory, and
search_long_term symbols when making the change.
- Around line 159-180: The legacy compatibility layer currently always
constructs a new SqliteMemoryAdapter and wires self._sqlite_adapter so every
store_* call duplicates writes; modify _init_legacy_compatibility to only create
a separate SqliteMemoryAdapter when the configured provider is not "sqlite" (or
when there is no existing SQLite-backed adapter), and when provider == "sqlite"
point self._sqlite_adapter to the current SQLite-backed adapter (or skip setting
up mirroring) so store_* methods do not double-write; update references to
self._sqlite_adapter, _local, _write_lock, _all_connections, and
_connection_lock accordingly and adjust the store_* call paths (the store_*
methods and the _init_legacy_compatibility function) to avoid writing twice.
- Around line 111-125: get_memory_adapter can raise RuntimeError when a
registered factory fails, preventing fallbacks; modify the adapter selection in
the initializer to catch RuntimeError around the call to

🛠️ Refactor suggestion | 🟠 Major
Move heavy knowledge backend registration to wrapper packages.
The registry abstraction is good, but wiring mem0/mongodb/chroma here keeps those backends compiled into praisonaiagents itself. To meet the wrapper-based extension goal, let the wrapper packages import and call register_knowledge_factory() instead of importing their factories from core.
As per coding guidelines "Core SDK (praisonaiagents) must use protocol-driven design with typing.Protocol for all extension points, not heavy implementations."

Don't forward registry-only kwargs into Mem0Adapter.
ProtocolDrivenKnowledge._get_adapter_config() passes config, verbose, and db_path, but Mem0Adapter.__init__() only accepts config and disable_telemetry. Mem0Adapter(**kwargs) will raise TypeError as soon as those common extras are present, so the mem0 backend cannot be created through the registry.

Don't gate plain-text Chroma usage on an unused markitdown dependency.
ChromaKnowledgeAdapter never calls self.markitdown, so this import makes the chroma backend fail unless an unrelated package is installed. If file parsing is optional, lazy-load MarkItDown only in the branch that actually needs it.

Apply scope and filters during Chroma searches.
add() writes user_id, agent_id, and run_id into metadata, but search() ignores those arguments and the filters parameter completely. In a shared collection this can return another user's or agent's documents.

Return a stable persisted ID, not id(text).
id(text) is only the in-process Python object identity, not the identifier of the stored memory record. Callers will get an ID they cannot reliably use later, and that value can be reused after garbage collection; generate a durable UUID or return the legacy backend’s real ID instead.

Catch factory errors before falling back.
get_memory_adapter() raises RuntimeError when a registered factory fails, so this code never reaches the sqlite/in_memory fallback for missing extras or bad backend config. A request for mem0, chroma, or mongodb can abort initialization outright instead of degrading gracefully.

The compatibility layer currently double-writes every store.
A second SqliteMemoryAdapter is always created, and both store_* methods always write through to it. With provider sqlite this inserts each record twice into the same DB; with any other backend it silently mirrors data to local SQLite and changes storage semantics.

agent_id and run_id are dropped here.
Only user_id affects the query path; when callers pass agent_id or run_id, this falls through to an unscoped search_long_term() call and never forwards either value to the adapter.

get_all() uses peek() which returns a sample, not all items.
ChromaDB's peek() method returns a random sample of documents for debugging purposes, not a complete listing. This means get_all() may return inconsistent and incomplete results, which also affects the scoped delete_all() branch that relies on it.
🐛 Proposed fix using collection.get()

🛠️ Refactor suggestion | 🟠 Major
Move these concrete backends out of praisonaiagents.
This file still embeds Mem0MemoryAdapter, ChromaMemoryAdapter, and MongoDBMemoryAdapter inside the core SDK. Lazy imports help import time, but they don't complete the core/wrapper split from #1306—core should keep the registry/protocols, while the wrapper package owns heavy backend implementations and auto-registers them.
Based on learnings "Use Protocol-driven core for praisonaiagents (no heavy implementations, only protocols/hooks/adapters/base classes) and move heavy implementations to the praisonai wrapper package".

Don't swallow Mongo text-index failures during initialization.
search_short_term() and the text-search fallback in search_long_term() both depend on $text. If create_index() fails here because of permissions or an incompatible existing index, the adapter still boots and the first search fails later with a much less actionable Mongo error. Log and raise, or explicitly disable $text search when index creation fails.
As per coding guidelines "Error handling: Fail fast with clear error messages; include remediation hints in exceptions; propagate context (agent name, tool name, session ID); provide hook points for error interception (on_error events)".

Import timezone separately; both write paths crash with AttributeError.
from datetime import datetime imports only the datetime class, which lacks a timezone attribute. Accessing datetime.timezone.utc raises AttributeError on the first insert in both store_short_term() and store_long_term().

Don't treat every ImportError as "adapter unavailable".
factory(**kwargs) / adapter_cls(**kwargs) can raise ImportError from the adapter's own code too, so this turns broken implementations into silent fallbacks and drops the install guidance the factory already produced.

Behavioral inconsistency: delete_all() without scope silently deletes everything.
Per relevant snippet from Mem0Adapter.delete_all(), the mem0 adapter raises ScopeRequiredError when no scope identifiers are provided. However, both ChromaKnowledgeAdapter and SQLiteKnowledgeAdapter silently delete the entire collection/table when called without scope.
This creates a breaking behavioral difference when users switch between adapters via the registry. A call like adapter.delete_all() could be safe with mem0 (raises) but destructive with chroma/sqlite.
Consider aligning behavior:
- Option A: All adapters require at least one scope parameter (defensive)
- Option B: Document the different behaviors clearly and leave as-is (if intentional)
# Example defensive approach for Chrome/SQLite:
if not any([user_id, agent_id, run_id]):
raise ValueError(
"delete_all() requires at least one scope parameter (user_id, agent_id, or run_id). "
"Use delete_collection() for full deletion."

Forward provider-specific store kwargs instead of rejecting them.
Memory.store_short_term() and Memory.store_long_term() now have closed signatures, but the delegated adapters are still open-ended (SqliteMemoryAdapter.store_* accepts **kwargs). Any backend-specific field now dies at the Memory boundary with TypeError instead of reaching the adapter. Add **kwargs to both wrappers and pass them through to the primary and compatibility adapters. As per coding guidelines, "Core SDK (praisonaiagents) must use protocol-driven design with typing.Protocol for all extension points, not heavy implementations."

305-360: Async variant doesn't follow the same adapter-first pattern as sync version.The
store_short_term_asyncmethod (lines 305-360) stores directly via_store_sqlite_stm(line 342) rather than delegating to the adapter first like the syncstore_short_termdoes. This inconsistency means async callers won't benefit from the protocol-driven architecture.Consider updating the async version to mirror the sync flow:

There was a problem hiding this comment.
Add defensive check before accessing _sqlite_adapter attributes.
If SqliteMemoryAdapter initialization fails (e.g., disk full, permissions), lines 273-276 will raise AttributeError when accessing _sqlite_adapter._local. Consider wrapping the adapter creation in a try-except or checking existence before accessing attributes.
