✨ 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 |
| 🛡️ | Prompt Hardening | Reference data markers (<<<REFERENCE_DATA_START>>>) + tool results are data-not-instructions safety rules |
| 📋 | 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) |
| 🔧 | 33 Built-in Tools | File system (14, incl. diff) · 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, access stats persisted per entry (TTL decay protection) |
| 📋 | Custom Files | SOUL.md (persona, never compressed) + AGENT.md (behavior rules, built-in fallback) + USER.md (user profile, workspace only, skipped if absent) |
| 🌐 | MCP Protocol Extension | JSON-RPC 2.0 over stdio, dynamic tool discovery, Shadowing protection |
| 🔍 | Web Search (dual-mode) | SearXNG meta-search JSON API (70+ engines) / quad-engine HTML parsing (Bing+Baidu+Sogou+360), switchable; web_fetch with auto-retry+mobile UA+SPA browser fallback |
| 🌏 | Browser Control | Open pages · Screenshot · JS execution · Content extraction · Click · Type · Scroll · Close |
| 🖥️ | Workspace Panel | Terminal (incremental streaming) + file browser, command security checks |
| 🔢 | Manual Context Length | Settings dropdown (128K / 256K / 512K / 1M), default 128K. Model bar shows configured value, dropdown shows per-model context length |
| 🗜️ | Smart Context Manager | Sliding window + Token auto-calibration + message importance scoring + LLM structured JSON compression, smart triggers (120 msg incremental + 300 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 SecurityCheck + FileWriteDedup |
| 👥 | Sub-agent Delegation | spawn_task tool, isolated context + timeout protection; permission tiers (readonly / limited_write / full_write) that can only be downgraded (capped by user setting); write tools share the main agent's confirmation pipeline; path sandbox covers all file tools |
| 📈 | Token Dashboard | Global + session stats, consumption trend bar chart, 2s refresh, input/output color-coded |
| 📋 | System Prompt Card | Collapsible card atop each AI reply — click to inspect the full context sent to the model |
| 🎨 | Warm-tone UI | Cream #FAF7F2 + coral #E8734A, fatigue-free for extended use, streaming render optimized |
| 🔔 | System Tray | Native tray integration |
| 🔐 | Backup Encoding | AES-256-GCM encoded session backups (key embedded in app — obfuscation against casual reading, not a security boundary) |
| 🧪 | Observability | Buffered trace persistence to SQLite + Agent Metrics dashboard with JSON / Prometheus text export |

🔒 Security
| Layer | Measure |
|---|---|
| 📁 File System | checkPathAllowed() — path blacklist (system + user-sensitive dirs); system dirs are a hard red line (not exempted even by workspace/allowlist) |
| 🧾 Identity File Protection | MEMORY.md blocked from all tools (memory tool only); SOUL.md / AGENT.md / USER.md read-only for tools (prevents prompt-injection persona hijacking; user-editable only) |
| ⚡ Command Execution | checkCommandAllowed() — command blacklist (POSIX + Windows) + three modes |
| 🔀 Argument Injection Guard | git user-controllable args must not start with - (blocks --upload-pack style injection); git add forces -- separator |
| 🌐 SSRF Guard | net-guard — web_fetch / download_file / browser_open block loopback/private/link-local addresses (DNS-resolved IP checked); browser_open allows http/https only |
| 🖥️ Frontend Rendering | HTML sanitizer (whitelist tags + URI protocol check); toast/HTML export use textContent/escapeHtml against XSS |
| 🔒 Electron | webSecurity: true (same-origin enforced; Ollama API precisely allowed via webRequest CORS allowlist) + contextIsolation: true + IPC whitelist + IPC fs path validation; agent browser uses memory: in-memory partition (cookies/storage wiped on exit) |
| 👥 Sub-agent Permissions | Permission tiers that can only be downgraded (capped by user setting); write tools share the main agent's confirmation pipeline; path sandbox covers all file tools |
| 🔐 Backup Encoding | AES-256-GCM (embedded key — obfuscation, not a security boundary) |
| 🧠 Memory Security | Pre-write prompt injection / sensitive info detection, multi-layer dedup filtering |
| 🌐 MCP Security | Shadowing protection + double-underscore delimiter disambiguation; paginated tools/list (nextCursor) |
| 🌐 Network Security | web_fetch streaming size limit (10MB) + OOM prevention without content-length; search reachability precheck fetches headers only (Range: bytes=0-0) |
| ⚡ Process Security | Windows taskkill forced termination + case-insensitive workspace path validation; workspace cannot be set to a system directory |
