## Project Renamed to CowAgent

The repository has been officially renamed from `chatgpt-on-wechat` to **CowAgent**, evolving into a full-featured AI Agent assistant.

- New URL: [github.com/zhayujie/CowAgent](https://github.com/zhayujie/CowAgent) — GitHub auto-redirects the old URL
- CLI commands, config files, and documentation links remain compatible — no extra steps needed

## 📚 Knowledge Base

New personal knowledge base system — Agent can autonomously build and maintain structured knowledge, retrieving it on demand during conversations:

- **Index-driven self-organizing structure**: Knowledge is stored in `knowledge/` directory, auto-organized by category, with each knowledge page as an independent Markdown file
- **Auto-write**: Send files, links, or other knowledge to the Agent, or it will automatically create/update knowledge pages when valuable information is identified in conversation
- **Hybrid retrieval**: Supports keyword full-text search and vector semantic retrieval, loading relevant knowledge on demand during conversations
- **Visualization**: File tree browsing and knowledge graph visualization, with in-document links for direct navigation
- **Command management**: `/knowledge` for stats, `/knowledge list` for directory structure, `/knowledge on|off` to toggle

## 🌙 Deep Dream Memory Distillation

A new memory consolidation mechanism that automatically distills scattered conversation memories into refined long-term memory daily:

- **Three-tier memory flow**: Conversation context (short-term) → Daily memory (mid-term) → MEMORY.md (long-term), forming a complete memory lifecycle
- **Auto-distillation**: Runs daily at 23:55, reads the day's daily memory and MEMORY.md, performs deduplication, merging, and pruning via LLM, outputting a refined MEMORY.md
- **Dream diary**: Each distillation generates a narrative-style dream diary recording discoveries and insights, stored in `memory/dreams/`
- **Manual trigger**: `/memory dream [N]` to manually trigger with configurable lookback days (default 3, max 30), with chat notification on completion
- **Web console**: Memory management page now includes a "Dream Diary" tab for browsing all dream diaries

## 🧠 Smart Context Compression

When context exceeds limits, trimmed portions are summarized by LLM and asynchronously injected to maintain conversation continuity:

- **Async LLM summary**: Trimmed messages are summarized into key information by LLM, written to daily memory files and injected into retained context
- **Multi-model compatible**: Uses the primary model for summarization, compatible with Claude, OpenAI, MiniMax and other model message format requirements

## 💬 Web Console Upgrades

Multiple enhancements to the Web console:

- **Multi-session management**: Create and switch between independent sessions, sidebar session list with auto-generated and manually editable titles
- **Password protection**: Set a login password via `web_console_password` config option
- **Deep thinking**: Display model thinking process in Web console, controlled by `enable_thinking` config option
- **Scheduled push**: Scheduled task results can be pushed to Web console
- **Message copy**: One-click copy of raw Markdown content from AI reply bubbles
- **Language toggle**: Top language switch button now shows current language for more intuitive interaction

## 🤖 Model Updates

- **Vision optimization**: Image recognition tool prefers the primary model with automatic multi-provider fallback. Docs: [Vision Tool](https://docs.cowagent.ai/en/tools/vision)
- **MiniMax new model**: Added MiniMax-M2.7-highspeed model and MiniMax TTS voice synthesis support. Thanks @octo-patch
- **Qwen**: Added qwen3.6-plus model support

## 🐛 Other Improvements & Fixes

- **Memory prompts**: `MEMORY.md` injected into system prompt by default, with refined memory retrieval and write trigger conditions for enhanced proactive writing
- **System prompt**: Optimized system prompt style and tone guidance
- **Browser tool**: Enhanced implicit interactive element detection
- **File send**: Fixed common file types (tar.gz, zip, etc.) not being sent correctly. Thanks @6vision
- **macOS compatibility**: Fixed network pre-check timeout compatibility issue. Thanks @Moliang Zhou
- **Windows compatibility**: Fixed PowerShell compatibility, process updates, terminal encoding and other issues on Windows
- **Python 3.13+**: Fixed missing `legacy-cgi` dependency for Python 3.13+
- **WeChat channel**: Updated personal WeChat channel version
