… shared helper (fixes #2118) - Extract common schema generation logic into build_parameters_schema() in tools/schema.py - Update BaseTool._generate_parameters_schema() to use shared helper - Update decorator._generate_schema_from_func() to use shared helper with injected param filtering - Update decorator._schema_from_function() to use shared helper - Fix is_injected_type() to handle bare Injected annotations (not just Injected[T]) - Fix resolve_injected_value() to handle bare Injected annotations This consolidates the duplicate logic with no behavior changes, making the codebase more maintainable.

Add injected parameter filtering to _schema_from_function to prevent leaking internal state parameters.
The _schema_from_function helper (line 300) only skips "self" when generating schemas for plain callables. If a plain function with Injected parameters is passed to get_tool_schema(), those internal state parameters will be exposed in the public schema. While @tool-decorated functions are protected via FunctionTool._generate_schema_from_func() (which uses a skip_predicate), the standalone helper lacks this safeguard.
Add the same injected parameter detection to _schema_from_function:
Suggested fix
def _schema_from_function(func: Callable) -> Dict[str, Any]:
"""Generate OpenAI function schema from a plain function."""
name = getattr(func, '__name__', 'unknown')
description = func.__doc__ or f"Function: {name}"
sig = inspect.signature(func)
hints = get_type_hints(func) if hasattr(func, '__annotations__') else {}
# Detect and skip injected parameters (same as FunctionTool)
injected_params = get_injected_params(func)
parameters = build_parameters_schema(
sig,
hints,
skip={"self"},
skip_predicate=lambda name, ptype: name in injected_params or is_injected_type(ptype),
func_name=name
)

Tighten the helper loop to avoid lint failures and silent partial schemas.
Line 192 leaves param unused. Additionally, lines 212–213 catch all exceptions at debug level only, allowing one unexpected failure to return a partially-built schema. Rename the unused variable to _param and narrow the exception handler to wrap only the risky call (annotation_to_json_schema), catching specific exception types and raising with parameter context and a remediation hint.
