- split monolithic _10_system_prompt.py into focused extensions: main (10), tools (11), mcp (12), skills (13), secrets (13), project (14)
- each extension exposes a build_prompt() function with call_extensions_async hook for plugin extensibility
- move tool prompt collection from VariablesPlugin to _11_tools_prompt using subagents.get_paths for proper directory coverage
- add {{include original}} directive to process_includes allowing prompt inheritance without copy-paste
- add agent.system.main.specifics.md for subagent-specific additions without overriding entire role
- remove redundant plugin prompt extensions (_15_text_editor, _20_code_execution) that duplicated tool collection
- add _09_text_editor_config to register per-file kwargs via agent.data instead of VariablesPlugin in prompts dir
- Add `watchdog` dependency to requirements.txt
- Implement cache entry timestamps with `CacheEntry` dataclass for LRU-style tracking
- Add `trim_cache` function to remove stale entries based on age
- Update cache operations to track and update entry timestamps on access
- Add `_get_matching_areas` helper for wildcard pattern matching in cache clearing
- Register watchdogs for API handlers, extensions, and plugins to
- Extract presets into global presets.yaml; move editor to plugin main screen
- Add project-wide override sync and three-layer permission checks
- Fix embedding change detection, new-chat inheritance, and preset name leak bugs
- Clean up dead imports/params and fix description text
Redesign extension handling to support explicit async/sync execution. helpers/extension.py rewrites the extensible decorator, adds call_extensions_async / call_extensions_sync, and a helper to gather extension classes; caching flag adjusted. Updated call sites across the codebase (agent, APIs, plugins, tools, settings, extensions) to use extension.extensible and the new call_extensions_async/sync API, and converted several extension handlers from async to sync. Also small frontend tweaks (use globalThis.runtimeInfo) and minor import updates (csrf_protect in run_ui). This centralizes extension discovery/execution and avoids previously scattered asyncio.run usage.
