+### 5️⃣ SquillaRouter — Token-Saving Cascade Router
+
+> *Per-turn model selection via adaptive cascade routing — saving ~40% tokens without quality loss.*
+
+GenericAgent now integrates **SquillaRouter**, an open-source cascade routing engine that selects the optimal LLM model tier at every turn. Instead of burning expensive models on trivial tasks, SquillaRouter classifies task difficulty and routes simple queries to lightweight models, reserving powerful models for complex reasoning.
+
+| Tier | Typical Model | Best For |
+| :---: | :--- | :--- |
+| **c0** | DeepSeek-Chat | Simple tool-call turns, status checks, trivial operations |
+| **c1** | DeepSeek-Chat / MiniMax | Most agent turns — balanced cost/quality |
+| **c2** | Gemini / Claude-Haiku | Code generation, multi-step planning, web interaction |
+| **c3** | Claude-Sonnet / GPT-5 | Deep reasoning, complex debugging, high-risk operations |
+
+**Key features:**
+- **Trajectory Classification**: Detects escalating, oscillating, or stable difficulty trends across turns
+- **Sticky Tier**: Resists unnecessary switching to avoid jitter
+- **Cascade Fallback**: If the preferred tier is unavailable, automatically falls back to the next best
+- **Zero-Config**: Drop-in activation via `SQUILLA_ROUTER=1` environment variable — no code changes needed
+
+```bash
+# Enable SquillaRouter
+export SQUILLA_ROUTER=1
+python launch.pyw
+```

+### 5️⃣ SquillaRouter — 省 Token 级联路由引擎
+
+> *每轮自适应选择最优模型 — 节省约 40% Token 而不损失质量。*
+
+GenericAgent 现已集成 **SquillaRouter**，一个开源级联路由引擎，在每一轮对话前根据任务难度自动选择最优模型层级。简单任务用轻量模型，复杂推理才切到强力模型，避免大材小用。
+
+| 层级 | 典型模型 | 适用场景 |
+| :---: | :--- | :--- |
+| **c0** | DeepSeek-Chat | 简单工具调用、状态检查、琐碎操作 |
+| **c1** | DeepSeek-Chat / MiniMax | 大多数 Agent 轮次 — 成本与质量平衡 |
+| **c2** | Gemini / Claude-Haiku | 代码生成、多步规划、网页交互 |
+| **c3** | Claude-Sonnet / GPT-5 | 深度推理、复杂调试、高风险操作 |
+
+**核心特性：**
+- **轨迹分类**：检测跨轮次的难度趋势（升级/降级/振荡/稳定）
+- **粘性层级**：避免不必要切换导致的抖动
+- **级联降级**：首选层级不可用时自动降级到次优
+- **零配置接入**：通过 `SQUILLA_ROUTER=1` 环境变量即可启用，无需修改任何代码
+
+```bash
+# 启用 SquillaRouter
+export SQUILLA_ROUTER=1
+python launch.pyw
+```

+# Security Audit
+
+## Overview
+
+Security review of GenericAgent core (`ga.py`, `agentmain.py`, `agent_loop.py`, `llmcore.py`, `launch.pyw`, `squilla_router/`).
+
+## Findings
+
+### 1. API Key Management ✅ Pass
+- `mykey.py` is in `.gitignore` (line 30) — not committed
+- `mykey_template.py` provides a safe template
+- API keys are loaded from `mykey.py` at runtime via `import mykey`
+
+### 2. Code Execution (`eval`/`exec`) ⚠️ By Design
+- `ga.py:304-305`: Uses `eval()` and `exec()` to run LLM-generated code
+- This is the core tool `code_run` — necessary for the agent to function
+- **Mitigation**: Code runs in the agent's process; users should run in isolated environments (VM/container) for untrusted tasks
+- **Recommendation**: Consider adding a `--sandbox` mode with Docker isolation
+
+### 3. Subprocess Usage ⚠️ By Design
+- `ga.py:58`: `subprocess.Popen` for user-specified commands
+- `agentmain.py:219`: `subprocess.Popen` for background tasks
+- **Recommendation**: Validate command arguments in high-security deployments
+
+### 4. HTTP Headers with API Keys ✅ Pass
+- `llmcore.py:406`: Bearer token via HTTPS only
+- Keys never logged or written to disk by GA core
+
+### 5. SquillaRouter ✅ Clean
+- No hardcoded secrets or API keys
+- Uses environment variable `SQUILLA_ROUTER` for activation
+- Model config in `config.py` is safe defaults, overridden by user
+
+### 6. File System Access ⚠️ By Design
+- `file_read`/`file_write`/`file_patch` tools can access any path
+- Agent has same file permissions as the running user
+- **Recommendation**: Run with least-privilege user account
+
+### 7. Shell Install Scripts ⚠️ Caution
+- `docs/installation.md` references `curl | bash` pattern
+- Users should review scripts before piping to bash
+- Scripts hosted on external domain (`fudankw.cn`)
+
+## Recommendations
+
+| Priority | Action |
+|----------|--------|
+| P0 | Run GA in isolated environment (VM/container) for production use |
+| P1 | Add optional `--sandbox` mode for Docker-based code execution |
+| P2 | Document that agent inherits user's file system permissions |
+| P3 | Consider code signing for install scripts |
+
+## Scope
+
+This audit covers the GenericAgent core and SquillaRouter. Third-party dependencies and frontends are not in scope.
