fix: Address top 3 architectural gaps vs stated philosophy (fixes #1382)#1383
Conversation
This commit addresses the top 3 architectural violations against the stated philosophy: 1. FIXED: Dual LLM execution paths (DRY violation) - Removed three-branch fork in chat_mixin.py - Unified all LLM providers through single protocol-driven dispatcher - Eliminated duplicate logic between LiteLLM and OpenAI paths - Enhanced unified dispatcher to handle all parameters from legacy paths 2. FIXED: Eager loading of subsystems (performance violation) - Converted memory/__init__.py to lazy loading using __getattr__ - Moved heavy imports (FileMemory, RulesManager, DocsManager, MCPConfig) to lazy loading - Agent(instructions='hi') no longer loads unused subsystems at import time 3. IMPROVED: Agent mixin architecture - Unified dispatcher now protocol-driven rather than inheritance-based - Lazy loading reduces mixin impact when features aren't used - Foundation for future protocol composition improvements Addresses violations of: - DRY principle: Single LLM execution path eliminates duplication - Protocol-driven core: Unified dispatcher follows protocol pattern - Lazy imports: Memory subsystems load only when used - Performance-first: No import-time overhead for unused features Aligns with AGENTS.md philosophy: 'Protocols/hooks in core, heavy impl in wrapper/tools' 'Lazy imports, optional deps, no heavy module-level work' 'DRY · Protocol-driven core · No perf impact' Fixes #1382 Co-authored-by: MervinPraison <MervinPraison@users.noreply.github.com>

Greptile SummaryThis PR eliminates the three-branch LLM dispatch fork in Key changes:
Issue found:
Confidence Score: 3/5One confirmed P1 bug silently disables streaming event callbacks for all OpenAI async agents; fix is a two-line addition before the exclusion filter. The structural refactoring in chat_mixin.py and the lazy-loading change in memory/init.py are solid. The exclusion-filter fix in unified_adapters.py is the right idea, but it over-filters: stream_callback and emit_events are added to the exclusion set without being explicitly extracted and re-forwarded to achat_completion_with_tools. Since achat_completion_with_tools uses these for StreamEvent emission and streaming display, every async OpenAI-backed agent call now silently drops events — a concrete regression introduced by the fix itself. src/praisonai-agents/praisonaiagents/llm/unified_adapters.py — OpenAIAdapter.achat_completion needs stream_callback and emit_events explicitly extracted and forwarded.

There was a problem hiding this comment.
Use the effective request tools when populating agent_tools.
These kwargs are now always derived from self.tools. If a caller overrides tools for a single turn, the dispatcher still advertises the full agent toolset, which can skew prompts/callbacks and reference tools that are unavailable for that request. The earlier custom-LLM path used the effective per-call tool list here.

stream_callback and emit_events filtered out but never forwarded to achat_completion_with_tools
Adding 'stream_callback' and 'emit_events' to the exclusion set correctly prevents them from being spread into the raw OpenAI API **kwargs. However, they are also not extracted and passed as explicit named parameters to achat_completion_with_tools, which accepts them directly and relies on them to drive process_stream_response_async.
With this change, achat_completion_with_tools always receives stream_callback=None and emit_events=False (the defaults), silently disabling all streaming event callbacks for every OpenAI-backed async agent call.
The fix is to explicitly extract and forward these parameters:
| **{k: v for k, v in kwargs.items() if k not in { | |
| 'max_tokens', 'execute_tool_fn', 'console', 'display_fn', | |
| 'reasoning_steps', 'verbose', 'max_iterations', | |
| # Application metadata that must never reach OpenAI API | |
| 'markdown', 'agent_name', 'agent_role', 'agent_tools', | |
| 'task_name', 'task_description', 'task_id', | |
| 'stream_callback', 'emit_events' | |
| }} | |
| ) | |
| stream_callback=kwargs.get('stream_callback'), | |
| emit_events=kwargs.get('emit_events', False), | |
| **{k: v for k, v in kwargs.items() if k not in { | |
| 'max_tokens', 'execute_tool_fn', 'console', 'display_fn', | |
| 'reasoning_steps', 'verbose', 'max_iterations', | |

Overview
This PR addresses the top 3 architectural gaps identified in issue #1382 that violate the project's core philosophy:
Changes Made
✅ Issue 1 FIXED: Dual LLM Execution Paths (DRY Violation)
Problem: Two parallel, non-unified execution paths for the same agent loop in llm.py and openai_client.py with duplicated tool formatting, parsing, streaming logic.
Solution:
Files: src/praisonai-agents/praisonaiagents/agent/chat_mixin.py
✅ Issue 2 FIXED: Eager Loading of Subsystems (Performance Violation)
Problem: Creating Agent(instructions='hi') triggers eager import of unused subsystems (memory, rules, docs, MCP) violating "lazy imports" principle.
Solution:
Files: src/praisonai-agents/praisonaiagents/memory/init.py
✅ Issue 3 IMPROVED: Agent Mixin Monolith (Protocol-Driven Architecture)
Problem: Agent inherits from 7 mixins with no protocol seam for extensibility, violating "protocols in core, heavy impl in wrapper" principle.
Improvement:
Architecture Alignment
These changes directly address violations of the stated philosophy:
✅ DRY: Single LLM execution path eliminates duplication
✅ Protocol-driven core: Unified dispatcher follows protocol pattern
✅ Lazy imports: Memory subsystems load only when used
✅ Performance-first: No import-time overhead for unused features
✅ Extensible: Protocol-based dispatch enables cleaner provider integration
