Code Review
This pull request refactors tool resolution across several framework adapters (AutoGen, AG2, CrewAI, and PraisonAI) to use a centralized ToolResolver and introduces protocol validation for registered adapters. However, several critical issues were identified in the review: a NameError in crewai_adapter.py due to mismatched loop variables, a syntax error and missing variables in praisonai_adapter.py caused by a duplicate agent creation loop, a logic issue in autogen_adapter.py where only the first task is executed in AutoGen v0.4, and overly strict parameter validation in registry.py that could reject valid adapters.

This loop introduces multiple critical NameErrors. By changing the loop variables from role, details to agent_name, agent_details, the rest of the loop (which still references details, role_filled, goal_filled, and backstory_filled) will crash immediately. Additionally, agent_tool_list is created but never used, as the context lines below still overwrite agent_tools using details. Reverting the loop variables to role, details and restoring the template formatting fixes these crashes while keeping the new warning logic.

This duplicate agent creation loop breaks the try block structure of the file, resulting in a syntax error (except ImportError as e: is left orphaned). It also removes the initialization of acp_enabled, lsp_enabled, and interactive_runtime, which are required later in the method and will raise NameErrors. The correct agent creation loop already exists later in the file (lines 146-176). Reverting this block to restore the try block and global variables fixes the syntax and runtime errors.
# Initialize InteractiveRuntime for ACP/LSP if enabled globally
global_config = config.get('config', {})
acp_enabled = global_config.get('acp', False)
lsp_enabled = global_config.get('lsp', False)
interactive_runtime = None
if acp_enabled or lsp_enabled:

from praisonai._async_bridge import run_sync

In the updated AutoGen v0.4 adapter, only the first task (combined_tasks[0]) is executed. Any subsequent tasks defined in the YAML configuration are completely ignored. To support multi-task workflows, all tasks should be combined into a single task description or executed sequentially, similar to the previous implementation.

There was a problem hiding this comment.
The validation strictly checks for inspect.Parameter.KEYWORD_ONLY. However, parameters defined as POSITIONAL_OR_KEYWORD (i.e., without the * separator in the function signature) can also be safely passed as keyword arguments. This strict check will cause false-positive TypeErrors for perfectly valid custom adapters. Allowing both KEYWORD_ONLY and POSITIONAL_OR_KEYWORD makes the validation more robust.

There was a problem hiding this comment.
RoundRobinGroupChat may run indefinitely
The old code wired TextMentionTermination("TERMINATE") | MaxMessageTermination(max_messages=20) so the team would stop when an agent said "TERMINATE" or after 20 messages. The new RoundRobinGroupChat(participants=agents) passes no termination_condition and no max_turns, so the stream will never stop on its own, exhausting the context window or running forever.

Enforce the exact keyword-only contract and distinguish protocol validation errors from constructor failures.
Line 74 accepts POSITIONAL_OR_KEYWORD, allowing adapters to pass validation even when their run() method defines parameters as positional-or-keyword instead of keyword-only (as required by the protocol). Additionally, line 111 catches all TypeError broadly, which masks not only protocol validation failures but also legitimate errors from the adapter's constructor—causing them to be silently reported as "unavailable" instead of surfacing the actual error.
Introduce a dedicated AdapterProtocolError exception, enforce strict keyword-only validation, and catch only that exception in is_available().
