Estimated code review effort🎯 4 (Complex) | ⏱️ ~45 minutes The changes introduce a multi-component architectural pattern across five files (one modified, three new modules, one new test file) with dense dispatch logic, adapter abstractions, and integration points. While individual files follow clear patterns, the diff spans heterogeneous concerns (adapters, mixin integration, module exports, testing) requiring separate reasoning for each cohort and understanding of the adapter-dispatcher abstraction's correctness.

Code Review
This pull request introduces a unified LLM protocol dispatch to consolidate dual execution paths (custom LLM vs OpenAI) into a single async-first architecture. Key changes include the addition of UnifiedChatMixin, UnifiedLLMDispatcher, and provider adapters. Feedback highlights several critical issues: flawed logic in message extraction for LiteLLMAdapter that could lead to duplicated prompts, and the use of dynamic class modification which hinders maintainability. Additionally, there is accidental file duplication between adapters.py and unified_adapters.py, redundant tool formatting calls, and unused variables. The test suite requires improvements, specifically replacing hardcoded absolute paths with relative ones and adopting a standard testing framework like pytest for better robustness and error handling.

The logic for extracting prompt, system_prompt, and chat_history from the messages list is flawed. It can lead to duplicated messages being sent to the LLM because the chat_history can include the message that is also being used as the current prompt. The chat_history should only contain messages prior to the current user prompt. This can lead to incorrect model behavior and wasted tokens.

Dynamically modifying self.__class__ is generally discouraged as it can lead to code that is hard to understand, debug, and maintain. It makes static analysis difficult and can cause unexpected side effects, especially if multiple instances of the same class exist.
A more maintainable approach would be to include UnifiedChatMixin in the Agent's class definition from the start and gate the unified dispatch logic with the _use_unified_llm_dispatch flag. This would make the code more explicit and predictable.
This pattern is repeated in _achat_impl on lines 1726-1728.

Using a hardcoded absolute path for sys.path modification makes the tests brittle and not runnable outside of the specific CI environment where this path is valid. This should be changed to a relative path calculation to ensure portability.

The tools argument passed to this method is already formatted by the caller in chat_mixin.py. Calling _format_tools_for_completion again here is redundant.

This test file is written as a standalone script with try/except blocks and print statements instead of using a standard testing framework like pytest. Using a proper test framework would provide better test discovery, execution, and reporting, and allow for using assertions (assert) for checks, which is more idiomatic for tests.

Catching a broad Exception and interpreting it as a skipped test because litellm might be missing is not robust. The test could fail for many other reasons, and this would mask the real error. It would be better to check for the presence of litellm explicitly and skip the test if it's not installed. If using pytest, you could use @pytest.mark.skipif.

3. Provider selection bypasses protocol dispatch 📎 Requirement gap ⚙ Maintainability
Unified dispatch selection is implemented via direct branching on _using_custom_llm and _openai_client inside agent code rather than being driven by the protocol layer. This keeps provider-selection logic in core/agent paths instead of protocol-driven adapter dispatch.
Agent Prompt
## Issue description
Provider selection logic lives in `UnifiedChatMixin` (agent layer) instead of being driven by the LLM protocol/adapter dispatch mechanism.
## Issue Context
Compliance requires protocol-driven provider dispatch so core/agent code does not branch on provider after initial selection.

This file appears to be a duplicate of praisonaiagents/llm/unified_adapters.py (same classes and factory) but the package exports in praisonaiagents/llm/__init__.py reference unified_adapters, not this module.

LiteLLMAdapter.chat_completion uses asyncio.run(...) and a thread pool fallback when already inside an event loop. This conflicts with the guidance in llm/protocols.py that sync implementations must not call asyncio.run() from library internals, and can also cause deadlocks/extra threads in async host apps. Consider implementing sync completion via the existing synchronous LLM.get_response(...) path (no event-loop juggling) and keeping the unified protocol async-first for async callers.

When stream=True, LiteLLMAdapter.achat_completion returns _convert_stream_response(response), but LLM.get_response_async(..., stream=True) appears to return a final str (per llm.py signature/usage) rather than an async stream. This makes the adapter’s streaming contract misleading and the sync wrapper may end up returning an AsyncIterator (or a single “chunk”) instead of a real Iterator, violating UnifiedLLMProtocol.chat_completion requirements for streaming. Consider treating LiteLLM streaming as “side-effect streaming” (console/events) while still returning a final ChatCompletion-shaped object, or implement a real iterator based on an actual streaming API.

LiteLLMAdapter._convert_response_to_standard_format returns a plain dict for string responses, but the rest of the agent/chat stack expects a ChatCompletion-like object with attribute access (e.g., response.choices[0].message.content, response.usage). With unified dispatch enabled and a custom LLM, this will raise at call sites. Consider wrapping LiteLLM results into the existing ChatCompletion dataclasses from llm/openai_client.py to maintain a consistent response type across adapters.

OpenAIAdapter.achat_completion/chat_completion accept a max_tokens argument but never pass it through to the underlying OpenAIClient call. This means unified dispatch will silently ignore max_tokens even when provided by the agent. Pass max_tokens through (either explicitly or by including it in the forwarded kwargs) so behavior matches the legacy path.

The unified dispatcher call here does not pass through critical parameters used by the legacy paths (e.g., execute_tool_fn, console, display_fn, verbose, stream_callback, emit_events, and agent metadata). As a result, tool execution and streaming/event emission behavior can differ or stop working entirely under unified dispatch. Consider forwarding the same arguments the legacy branches pass to LLM.get_response* / OpenAIClient.chat_completion_with_tools so unified mode is functionally equivalent.

This opt-in path mutates the instance’s class at runtime (self.__class__ = type(...)) to inject UnifiedChatMixin. Changing __class__ dynamically can break type checks, pickling, introspection, and can be risky in concurrent usage (multiple threads/tasks calling chat on the same Agent). Prefer a stable composition approach (e.g., always include the mixin in the Agent MRO, or delegate to a helper object) without altering the runtime type.

In the unified async path, the code assumes response has attribute-style access (response.choices[0].message.content). However, UnifiedLLMDispatcher can return a plain dict (e.g., LiteLLMAdapter wraps string responses into a dict), which will raise AttributeError here. To keep unified dispatch usable across providers, ensure the dispatcher/adapters always return the same ChatCompletion-shaped type (or normalize the response before accessing .choices).

This test script hard-codes a GitHub Actions runner path into sys.path (/home/runner/work/...). This will fail when run locally or in other CI environments.

- Around line 1730-1755: The unified async branch returns early and skips the
normal response lifecycle (appending/persisting assistant messages, running
guardrails/self-reflection) and forces response_format=None; instead, have
_unified_achat_completion return a response that preserves the original
response_format and then run the same post-processing flow used elsewhere: call
_achat_completion when tools are present (as currently done), ensure assistant
messages are appended/persisted the same way as the non-unified path, run
guardrails/self-reflection hooks, and only then call
_execute_callback_and_display and _atrigger_after_agent_hook with the finalized
result; update the call site to not hardcode response_format=None and ensure
unified path reuses the same helper(s) that perform lifecycle steps so behavior
remains identical to the non-unified branch.
- Around line 539-541: The unified dispatch flag check
(_use_unified_llm_dispatch) is only applied in the OpenAI-oriented path, leaving
chat() and achat() to use the legacy self._using_custom_llm branches and
llm_instance path; update the custom-LLM branches to honor the flag by adding
the same getattr(self, '_use_unified_llm_dispatch', False) conditional where
chat() and achat() choose execution flow so they route through the unified
dispatch path when enabled (modify the branches that currently check
self._using_custom_llm and llm_instance to first check _use_unified_llm_dispatch
and follow the unified dispatch code path); ensure the same change is applied to
the other occurrence noted in the file that mirrors these branches.
In `@src/praisonai-agents/praisonaiagents/agent/unified_chat_mixin.py`:
- Around line 82-95: The dispatcher.chat_completion call in unified_chat_mixin
(method using final_response) is missing legacy execution/display kwargs (e.g.,
execute_tool_fn, console/display callbacks, verbosity flags) that the old
completion path forwarded; update the call sites (the block invoking
dispatcher.chat_completion around final_response and the similar block at the
later call site) to include and pass-through those kwargs from the agent
instance or method parameters (preserve execute_tool_fn, any console/display
callback args, and verbosity controls) so the dispatcher receives the same
execution/display behavior the adapters expect; reference the
dispatcher.chat_completion invocation and ensure the extra kwargs are included
in the **{...} expansion or kwargs dict you pass.
In `@src/praisonai-agents/praisonaiagents/llm/unified_adapters.py`:
- Around line 74-76: OpenAIAdapter and LiteLLMAdapter must return the same
"completion" shape (object with attribute access) so callers in chat_mixin can
use dot access; update LiteLLMAdapter's stream and non-stream conversion code
(notably _convert_stream_response and the non-stream response conversion around
lines 137-161) to wrap raw dicts/chunks into a lightweight object exposing the
same attributes OpenAIAdapter returns (e.g., .choices, .content/.message,
.usage, etc.), or construct a unified Completion-like class/namespace and return
instances of that for both streaming and non-streaming paths so both adapters
conform to the same protocol used by chat_mixin.
- Around line 62-70: UnifiedChatMixin is passing max_tokens but the async
adapter methods are not forwarding it, so update LiteLLMAdapter.achat_completion
and OpenAIAdapter.achat_completion to accept and forward the max_tokens
parameter to their internal/delegate async calls (the methods that actually call
the underlying client or delegate async completion routine). Ensure the
parameter name max_tokens is added to the async method signatures and passed
through in the call to the delegate (and any kwargs unpack) so per-agent token
limits are honored for async get_response_async flows.
In `@src/praisonai-agents/test_unified_llm.py`:
- Around line 11-12: The test hardcodes sys.path.insert(0,
'/home/runner/work/PraisonAI/PraisonAI/src/praisonai-agents') which pins imports
to one GitHub Actions workspace; remove that hardcoded path and instead make the
test import the package normally (rely on pytest/package-relative imports) or
document using an editable install or setting PYTHONPATH for local/CI runs;
locate and update the sys.path.insert call in
src/praisonai-agents/test_unified_llm.py (or replace with proper package
import/setup) so tests are portable across environments.
- Around line 14-108: Replace the broad try/excepts and print/return False
patterns in test_unified_protocol_imports(), test_basic_agent_functionality(),
test_unified_dispatcher_creation(), test_agent_with_unified_dispatch(), and
test_backward_compatibility() with real pytest assertions (no silent catches) so
import failures and construction errors fail CI; specifically assert imported
symbols (UnifiedLLMProtocol, LiteLLMAdapter, OpenAIAdapter,
UnifiedLLMDispatcher, create_llm_dispatcher), assert Agent fields directly, and
assert dispatcher creation (create_llm_dispatcher with LLM and OpenAIClient)
without swallowing exceptions. Add one end-to-end unified-dispatch test that
sets Agent._use_unified_llm_dispatch = True, calls agent.start(...) (or
Agent.start_async if applicable) with a real prompt, ensures a dispatcher is
created via create_llm_dispatcher/OpenAIClient or LLM, and asserts the
returned/completed response text is non-empty (and optionally contains expected
substrings); fail the test if no OPENAI_API_KEY is provided or mark it to skip
via pytest.skip to avoid false CI passes. Ensure references to symbols: Agent,
Agent.start, _use_unified_llm_dispatch, create_llm_dispatcher, OpenAIClient, and

The async unified branch skips the normal response lifecycle.
This returns before assistant messages are appended/persisted and before guardrails or self-reflection run, and it forces response_format=None. Turning the flag on changes user-visible behavior instead of only swapping the backend call.

Preserve the legacy execution/display kwargs when routing through the dispatcher.
The old completion paths passed execute_tool_fn, console/display callbacks, and verbosity controls into the LLM client. Dropping them here breaks tool-call parity for the sync unified path and strips behavior the adapters already support.

Return one completion shape from every adapter.
OpenAIAdapter hands back the client’s ChatCompletion-like object, but LiteLLMAdapter converts responses/chunks into raw dicts. The unified callers in src/praisonai-agents/praisonaiagents/agent/chat_mixin.py use attribute access, so the LiteLLM-backed path cannot be consumed through the same protocol today.

Make these real pytest assertions and add one end-to-end unified-dispatch run.
Catching Exception and returning False still counts as a passing test in pytest, so broken imports or dispatcher construction won’t fail CI. Also, none of these cases enable _use_unified_llm_dispatch and drive the agent through an actual completion call, so the new execution path is still untested.
Based on learnings: "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".

"First message" and the assistant "Response"; update the assertions in the block
referencing mock_get_response, call_kwargs, chat_history, prompt, and
system_prompt to assert len(chat_history) == 2 and that the assistant entry is
the last item (e.g., chat_history[-1]['content'] == "Response") while keeping
the existing checks that call_kwargs['prompt'] == "Second message" and
call_kwargs['system_prompt'] == "You are helpful".

custom-provider agents still take the legacy path; move or duplicate the
unified-dispatch check so it short-circuits before any legacy _using_custom_llm

an explicit top-level guard that calls _execute_unified_chat_completion(...)
when _use_unified_llm_dispatch is True (and returns), ensuring the unified path

- Around line 160-195: The adapter currently returns plain dicts from
_convert_response_to_standard_format and _convert_chunk_to_standard_format which
breaks callers that use attribute access (e.g.
response.choices[0].message.content and response.usage); modify both converters
to return objects that preserve the OpenAI-like attribute access shape (choices
as list of objects with .message or .delta objects with .content) and include a
.usage attribute when available (or a default usage object) so token accounting
still works; update _convert_chunk_to_standard_format to wrap string chunks into
the same object structure used by _convert_response_to_standard_format and
ensure types returned by _convert_stream_response are consistent (async yields
of these wrapped objects) so unified callers continue using dot-notation without
changes.
In `@src/praisonai-agents/test_unified_llm.py`:
- Around line 135-148: Add an end-to-end test instead of only asserting the
flag: enable _use_unified_llm_dispatch on an Agent instance (Agent), call
agent.start(...) with a real prompt (agent.start()) so the LLM is invoked, await
the result, and assert the returned text is non-empty; additionally verify the
unified-path methods (_execute_unified_chat_completion and
_execute_unified_achat_completion) were used (via a lightweight spy/patch) or at
least exist, and include an assertion that response_format behavior for the
unified branch matches expected output to catch the async response_format bug.

Line 1854 references undefined response_format in async unified dispatch branch.
The _achat_impl() method (line 1603) does not receive response_format as a parameter and never assigns it locally. When _use_unified_llm_dispatch=True, line 1854 will raise a NameError, causing the unified dispatch path to fail silently and return None.
Add logic to build response_format from the available output_pydantic or output_json parameters, similar to the sync path. The fix should check if native structured output is supported and build the format accordingly before the unified dispatch call.

This assertion expects the wrong history shape.
The adapter removes the leading system message and uses the last user turn as prompt, so chat_history here is only First message + Response. len(chat_history) == 3 will fail.
Suggested fix
- assert len(chat_history) == 3 # system excluded, contains first user + assistant + user
- assert chat_history[-2]['content'] == "Response"
+ assert chat_history == [
+ {"role": "user", "content": "First message"},

This commit addresses Issue #1304 by consolidating the dual execution paths in the LLM layer (LiteLLM vs OpenAI) into a single async-first protocol-driven architecture, eliminating DRY violations and maintenance burden.
Key changes:
Benefits:
✅ Single async chat completion implementation
✅ Sync methods as thin wrappers around async
✅ Protocol-driven provider selection
✅ Elimination of dual execution paths
✅ All existing functionality preserved
Files added:
Files modified:
The unified dispatch is opt-in via _use_unified_llm_dispatch flag, ensuring zero impact on existing deployments while enabling clean migration path.
