Design Philosophy

FastClaw is built on the core concept of event-driven agent orchestration. Key design principles:

• Graph-based Agent: Uses a directed graph to orchestrate agent behavior, supporting conditional branching between nodes (e.g., tool execution, response generation)
• Event Streaming: Real-time streaming output of LLM responses for better user experience
• Tool System: Extensible tool framework supporting Shell commands, skills, and custom integrations
• Session Management: Persistent conversation history with multi-session support
• Cron Scheduling: Built-in cron-style task scheduling for automated workflows

Features

• 🤖 LLM-powered - Built on FastMind framework with streaming support
• 🔧 Tool Calling - Execute Shell commands, skills, and more
• ⏰ Cron Jobs - Schedule tasks with cron expressions
• 💬 Multi-channel - Feishu, iMessage integrations
• 🎨 Extensible - Easy to add custom skills and agents
• 🐍 Python Ecosystem - Seamlessly call professional libraries like numpy and pandas, enabling AI to use Python ecosystem tools as skillfully as humans

Changelog

v1.1.7 (2026-05-21)

• 🐛 Fix: Context unloading now only affects LLM input, messages.jsonl always keeps full history
• 🐛 Fix: Message timestamps are no longer overwritten on every save
• 🐛 Fix: CancelledError no longer triggers duplicate response generation
• 🧪 Test: Added context unloading, sliding window, and timestamp preservation tests
