v0.12.0

Highlights

Unified sync/async Tool execution — all tools now work transparently with both run() and arun(), regardless of whether the underlying function is sync or async.

Changed

• Unified Tool callable layer with _FunctionToolWrapper: all Tool.callable values are now BaseToolWrapper subclasses, providing uniform call_sync()/call_async() interfaces regardless of tool origin (native function, MCP, OpenAPI, LangChain).
• Tool.run() / Tool.arun() are now the primary API: exceptions propagate directly instead of being swallowed and returned as error strings.
• Tool.run_raw() / Tool.arun_raw() are now deprecated aliases for run() / arun(). They emit DeprecationWarning and will be removed in a future version.

Added

• Tool.fn property: access the underlying unwrapped function.
• Sync/async transparency: sync tools can be called via arun() (asyncio.to_thread), async tools via run() (asyncio.run).
• Parallel execution: mixed sync/async tools work with asyncio.gather().

Fixed

• arun()/arun_raw() crashing on sync callables ("object can't be used in 'await' expression").
• run()/run_raw() returning bare coroutine objects for async callables.
• Executor context injection (_ctx) not detecting parameters through tool wrappers.

Removed

• make_sync_wrapper() from executor helpers (dead code after wrapper unification).
