WalkthroughThis changeset integrates Google AI support across the backend director module. New enum members are added to expand language model options, and logic in the default LLM selector now accounts for Google AI based on environment variables. A dedicated module is introduced for handling Google AI functionalities, including chat completions and configurations. Additionally, agent parameter handling has been refined: parameters are filtered in the BaseAgent, the dubbing agent’s extra engine parameters are removed, and the UploadAgent now requires a Changes

22-22: Addition ofGOOGLEAIenum value
This new enumeration for Google AI is consistent with the existing pattern for LLM types.
31-31: Addition ofGOOGLEAI_environment prefix
This new environment prefix aligns well with the naming of other prefixes.backend/director/llm/__init__.py (2)
7-7: New import for GoogleAI
No concerns with importingGoogleAI.
24-25: Conditional fallback for Google AI
The new branch for returningGoogleAIis consistent with the handling for other LLM providers.backend/director/llm/googleai.py (10)
1-2: Initial imports
No issues found with the added imports for JSON and Enum.
4-5: Pydantic import statements
The imports for validators and settings appear correct.
7-12: Imports from director modules
The references toRoleTypes,BaseLLM, and related classes look correct and consistent.
15-21: Definition ofGoogleChatModelEnum
Enumerating multiple Gemini chat models is clear and consistent with naming conventions.
23-49:GoogleAIConfigclass implementation
The config class usesSettingsConfigDictand an appropriate validator forapi_key. This is a solid approach.
50-58: Initialization ofGoogleAI
The constructor properly creates aGoogleAIConfigwhen none is provided and initializes the base LLM.
63-65: Verify use ofopenai.OpenAI(...)for Google Gemini
The code currently constructsself.clientusingopenai.OpenAI(...), which is typically associated with OpenAI endpoints. Make sure this approach is truly compatible with Google Gemini, or confirm that you intend to leverage the OpenAI client library for interfacing with Google’s API.
67-115:_format_messagesmethod
This method’s logic for handling system, assistant, tool, and user roles is well-structured and follows typical patterns for multi-turn conversation handling.
117-131:_format_toolsmethod
The approach of enumerating functions for Gemini is clean and straightforward.
134-197:chat_completionsmethod body
The method is logically clear: it formats parameters, handles the API request, parses the response, and captures metadata. Overall, it’s neatly organized.

🛠️ Refactor suggestion
Use proper error handling and logging instead of print statements.
Using print for error logging isn't recommended in a library. Also, the error response should have an ERROR status.
try:
response = self.client.chat.completions.create(**params)
except Exception as e:
- print(f"Error: {e}")
- return LLMResponse(content=f"Error: {e}")
+ import logging
+ logging.error(f"Google AI chat completion error: {e}")
+ return LLMResponse(
+ content=f"Error: {e}",
+ status=LLMResponseStatus.ERROR

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

51-56: Be cautious about discarding optional parameters.
This filtering retains only the properties listed under"required". If your function has optional parameters you'd like to document or validate, they won't appear in this final schema.
58-62: Return structure aligns with JSON schema, but consider adding more information.
The returned object properly sets"type":"object"and includes minimal keys. If you want richer schema metadata (e.g.,"description", nested properties, or examples), it might help downstream integrations.backend/director/handler.py (1)

43-44: Check if excludingargsandkwargsis intentional.
By popping these entries fromparameters["properties"], the schema omits them from validation. This is fine if your design never needs those parameters, but if there's any dynamic argument usage, consider preserving them.
46-49: Ensureargsandkwargsremoval fromrequiredmatches desired usage.
Removing"args"and"kwargs"from the"required"list is consistent with the approach above. Just confirm these parameters are never mandatory for your agent.backend/director/handler.py (2)

Review Note: Confirm Intentional Removal of Dubbing Functionality
It appears that the
ChatHandlernow has theDubbingAgentinstantiation commented out (line 65 inbackend/director/handler.py). Our search confirms that while theDubbingAgentclass is still defined inbackend/director/agents/dubbing.pyand imported inChatHandler, there are no other references or API routes relying on it. This indicates that the dubbing functionality is effectively disabled.Please confirm whether this change is intentional as part of the Google AI integration. If the removal is deliberate, ensure that the decision is documented so that users relying on the dubbing feature are aware of the change.

Impact of Removing UploadAgent from ChatHandler
Our investigation confirms that while the
UploadAgentremains defined inbackend/director/agents/upload.pyand its import is still present inbackend/director/handler.py, the actual usage in the ChatHandler has been commented out. Additionally, the fallback logic inbackend/director/core/reasoning.pyexplicitly references the upload agent (to generate a video_id when needed).
- Location Check:
backend/director/agents/upload.py: Contains theUploadAgentclass.backend/director/handler.py: The line invokingUploadAgentis commented out, although the import still exists.backend/director/core/reasoning.py: The fallback behavior relies on the upload agent.If disabling the upload functionality via the ChatHandler is part of the intended Google AI integration, please document the rationale. Otherwise, if this was inadvertent, you may need to restore its functionality to support the fallback process.

18-45: Consider removing commented-out code after successful transition to dynamic parameters.The code has been changed to use a dynamic parameter retrieval method (

57-57:✅ Verification successful
Verify parameter structure consistency with get_parameters() method.
Ensure that the
get_parameters()method returns a structure consistent with the previous static definition, including all required fields and proper type definitions.
🏁 Script executed:
#!/bin/bash # Check the implementation of get_parameters() in BaseAgent rg -A 10 "def get_parameters" --type pyLength of output: 958
Parameter Structure Verified – No Action Required
The implementation ofget_parameters()inBaseAgentnow dynamically infers the JSON schema from the associated run function. The method retrieves the parameters viafunction_inferrer.to_json_schema(), raises an exception if parameters are missing, and explicitly removes the unwanted"args"property from the schema. This strategy appears to maintain consistency with the previously static parameter definition by ensuring that the required fields and type definitions are derived at runtime.
- Action: Confirm via integration tests that the dynamically generated JSON schema (including keys like
"properties","required", and any type definitions) matches the expected structure for all agents (e.g., inupload.pyat line 57).

44-44: Good parameter requirement update.Updating the required parameters to only include
media_typeandcollection_idmakes sense. This change aligns with the more flexible approach wheresourcecan be provided as either a URL or local file path, and is validated separately.
63-68: Good input validation implementation.Adding validation for the
sourceparameter is a good defensive programming practice. This ensures that the upload operation receives valid input data and fails gracefully with a clear error message when requirements aren't met.
