Summary of Changes
Hello @haochengxia, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request addresses a signature error in the plugin example by updating the Python hook function definitions and their corresponding documentation. It also adjusts cache sizes in the example for potentially better demonstration or testing.
Highlights
- Documentation Update: I've added explicit signature requirements for Python cache hook functions in the
plugin.mddocumentation. - Hook Signature Correction: I've corrected the signatures of
cache_hit_hookandcache_eviction_hookinplugin_cache.pyto correctly accept aRequestobject. - Example Cache Size Adjustment: I've reduced the default cache size in the
plugin_cache.pyexample to1024for both the plugin and reference LRU caches.

Code Review
This pull request fixes signature errors in the plugin example and updates the documentation accordingly. The changes in the example code correctly align the hook function signatures with the plugin system's expectations. I've found a couple of minor issues in the documentation and a small style improvement for the example code. Specifically, there are syntax errors in the type hints in plugin.md, and an unused parameter in plugin_cache.py could be marked as such for clarity. Overall, this is a good fix.

There are syntax errors in the return type annotations for cache_remove_hook and cache_free_hook. The trailing colon ->: is invalid. Based on the example implementation, these functions do not return a value, so the return type should be None.
| def cache_remove_hook(data: CustomizedCacheData, obj_id: int | str) ->: ... | |
| def cache_free_hook(data: CustomizedCacheData) ->: ... | |
| def cache_remove_hook(data: CustomizedCacheData, obj_id: int | str) -> None: ... | |
| def cache_free_hook(data: CustomizedCacheData) -> None: ... |

The request parameter is unused in this function. To improve code clarity and signal that this is intentional, it's a good practice in Python to prefix unused parameters with an underscore.
