Freeze all leading system prompt blocks per conversation, including the main prompt, skills, workspace context, recent conversations, personalization, AGENTS.md, custom system prompts, and disabled-tool notices. Tool schemas remain dynamically generated outside the frozen prompt path.
Remove obsolete prompt injection files and code paths for thinking mode, deep thinking mode, sub-agent guidelines, and todo guidelines so prompt assembly stays simpler and cache-friendly.
Add personalization-controlled conversation_continuity with high/medium/low levels, rename the UI copy to 对话连续性, and wire it through backend sanitization, prompt generation, manage_personalization, frontend settings, and tool result rendering.
Add auto communication style support via prompts/auto_style.txt, matching the existing separate-file pattern used by human_like_style.txt.
