Add @extension.extensible decorators to all plugin API handler methods and core plugin functions to enable extension points. Implement plugin hooks system allowing plugins to define custom behavior via hooks.py file. Add call_plugin_hook function to execute plugin-specific hooks for events like uninstall, save_plugin_config, and get_plugin_config. Introduce uninstall_plugin function that calls uninstall hook before deletion. Move circular
The provider manager now uses the plugin cache system and automatically reloads when plugins change, making the explicit reload_providers() call unnecessary.
Add plugin_names parameter to after_plugin_change() and send_frontend_reload_notification() to enable targeted extension checking. Only send reload notification if changed plugins have webui extensions (checks extensions/webui directory existence). Defer notification send by 1 second to allow multiple rapid changes to coalesce. Update delete_plugin() to send notification before deletion for proper extension checking. Pass plugin names
Introduce validate_tool_request() extensible method in agent.py to validate tool request structure (dict with tool_name string and tool_args dict fields) before processing. Add after_plugin_change() helper in helpers/plugins.py that clears cache and sends a frontend reload notification (throttled to display_time interval) with a reload button. Update plugin installer install/delete flows to call after_plugin_change(). Extend notification
Add extension hooks and improve plugin cache handling. Changes include:
- Add new JSON API extension points and a cache reset handler (extensions/webui/json_api_call_before, json_api_call_after/cache_reset.js) to clear frontend cache when backend cache_reset runs.
- Rename webui extension hook directories to use fetch_api_call_* naming.
- Refactor webui/js/api.js to normalize API URLs, lazily import ./extensions.js, and call extension hooks for json_api_call_before/error/after and fetch_api_call_before/after using a ctx object.
- Rename invalidate_plugin_cache to clear_plugin_cache and call it after plugin install/delete/toggle/config save to keep plugin cache consistent.
- Harden plugin name sanitization to replace non-alphanumeric chars with underscores.
- Include extensions/**/*.js in jsconfig.json for editor tooling.
These changes improve extensibility for API lifecycle events and ensure plugin-related cache is cleared when plugin state changes.
