Features

Feature Description
🤖 ReAct Agent Loop Always-on, only chat mode. 8-state machine, up to 85 iterations (configurable), smart retry (permanent errors return immediately, transient errors use exponential backoff), tool dedup, path-aware dependency serialization, watchdog + tiered timeout protection
🛡️ 5-Layer Anti-Hallucination Prompt hardening → task awareness → mid-task detection (bilingual CN/EN rules covering all tool categories) → progress anchors → completion gate (6 checks: hallucination/injection → block, quality/efficiency → advisory)
📋 Plan Mode Toggle switch. AI first generates an execution plan (Markdown-rendered confirmation dialog), then tracks step-by-step execution, supports resume (interrupted plans restore on next session)
🔧 40 Built-in Tools File system · Command · Web search · Browser · Git · Memory · Sessions · Sub-agent · System · Plan Mode tracking
🧠 Smart Memory System Three types (fact / preference / rule), stored in workspace MEMORY.md file, path-protected — only the memory tool can access it, pre-write security scan, 500 capacity, auto-extract on conversation end, strict format validation

🗜️ Smart Context Manager Sliding window + Token auto-calibration + message importance scoring + LLM structured JSON compression, smart triggers (120 msg incremental + 200 msg hard limit)
⏱️ Smart Timeout Protection Agent Loop watchdog (configurable, default 30min) + stream total timeout (configurable, default 300s) + configurable HTTP/MCP timeouts
🪝 Hook System 4-phase lifecycle hooks (pre_tool / post_tool / post_iteration / pre_completion), built-in security check, file dedup, auto plan tracking, change audit, result validation
👥 Sub-agent Delegation spawn_task tool, isolated context + timeout protection
📈 Token Dashboard Global + session stats, consumption trend bar chart, 2s refresh, input/output color-coded
