Conversation
- Remove redundant framework availability wrappers in auto.py that only delegated to is_available() - Make agents_generator module-level constants lazy via __getattr__() to avoid import-time probes - Fix async bridge singleton creation (now lazy) and encapsulation breaks in run_sync() - Deprecate AutoGen-specific methods in ToolRegistry to guide toward proper separation Addresses three key architectural violations: 1. DRY violation: 8 wrapper functions that added no value over is_available() 2. Import-time work: 6 package probes ran on every agents_generator import 3. Encapsulation break: run_sync() accessed private _BG._lock directly Performance impact: Eliminates import-time package probing and eager singleton creation.

Greptile SummaryThis PR eliminates three architectural violations in the wrapper layer: it removes 8 redundant availability-check wrappers from
Confidence Score: 5/5Safe to merge; the changes are mechanical refactors that preserve all existing behaviour through deprecation warnings and backward-compatible fallbacks. All four files make narrow, targeted changes: wrapper functions are deleted and call sites updated to their direct equivalents, the async singleton is lazily created with correct double-checked locking, and the AutoGen deprecation path still routes through the same storage. No core execution paths are altered. The two findings are limited to the star-import surface and the repeated-dispatch behaviour of the getattr hook, neither of which affects normal imports or runtime logic. No files require special attention beyond the all narrowing in agents_generator.py. Important Files Changed

🧩 Analysis chain
🌐 Web query:
In Python, if a module defines __getattr__ for missing attributes, will from module import *anddir(module)include those dynamically provided names, or do you needall/dir as well?
💡 Result:
In Python, defining a module-level getattr does not automatically cause those dynamically provided names to be included in from module import * or dir(module). To ensure your dynamically generated attributes are visible in these contexts, you must also define a module-level dir function [1]. 1. from module import *: This operation relies on the all list if it exists in the module. If all is not defined, from module import * imports all names in the module except those beginning with an underscore [2]. Because getattr is only triggered during explicit attribute access, it is not consulted when Python constructs the list of names for a wildcard import. Consequently, you must explicitly include these dynamic names in your module's all list (if you have one) for them to be picked up by wildcard imports. 2. dir(module): The dir() function returns a sorted list of valid attributes for an object [1]. For modules, if you do not define a custom dir function, dir() will only return the names currently defined in the module's dict (plus standard module attributes like name and file). It does not trigger getattr to discover potential dynamic names. To make dir() aware of your dynamic attributes, you must define a dir function at the module level that returns a list (or iterable) containing both the static and dynamic attribute names [1]. In summary, getattr provides a mechanism for accessing attributes that do not yet exist, but it is effectively invisible to introspection tools and bulk-import mechanisms unless you explicitly expose those names via all and dir [3][1]. Top results: [3][1]

Restore legacy flag discoverability for from ... import * / dir()
__getattr__ makes module.FLAG work at access time, but it does not make those legacy names visible to from ... import * or dir(module). To preserve the stated compatibility surface, add module-level __all__ and a matching __dir__() that includes the _AVAIL keys.

Avoid surfacing deprecation warnings from an internal compatibility path.
AgentsGenerator.__init__() still calls register_builtin_autogen_adapters(), so regular generator construction now goes through a deprecated path and can warn once here plus once per adapter via register_autogen_adapter(). That turns a non-deprecated code path into warning noise, and it will break warning-strict test runs. Keep the fallback silent while it is still used internally, or remove the internal call in the same PR.
Also applies to: 125-145

2. Async Bridge Singleton & Encapsulation
3. Tool Registry Separation

Backward Compatibility
All changes maintain backward compatibility through deprecation warnings and fallback behavior.
