研究方向

Start by understanding the current implementation of the no unused prop types rule, likely in the file `lib/rules/no unused prop types.js`. The issue reveals that when `skipShapeProps` is true, the rule fails to detect unused properties that are inside a nested object pattern (like `props.nested.text`). Investigate how the rule traverses propTypes and JSX usage, and consider how it handles destructured or nested access. The fix might involve extending the detection to cover cases where the property is accessed via a chain like `props.nested.something`. Review existing tests for the rule to understand the expected behavior.
