-- [Global Memory]: Branch-local lessons are lost after archival. Use Global Lessons Registry for persistence.
-- [Format Safety]: Do not copy line numbers from view tools; they break file edits.
-- [Path Rewrite Guard]: Namespace migrations should validate for accidental double-prefix replacements like `agentcortex/agentcortex/...` immediately after bulk path rewrites.
-- [Wrapper Validation]: Validation checks for wrapper files should assert behaviorally equivalent path construction patterns, not only one literal path string representation.
-- [Bash Portability]: Shell validation entrypoints should prefer portable `grep`-based checks over environment-specific `rg` assumptions when they are part of cross-platform integrity gates.
-- [Work Log Key]: Resolve filesystem-safe worklog keys from raw branch names before gate checks; missing active logs are recoverable, while missing handoff references or evidence remain hard failures.
-
-- [GLOBAL-CANDIDATE][Patch Path Fallback]: When `apply_patch` is unstable on this Windows workspace, prefer repo-local safe whole-file rewrites only for newly added files or tightly scoped text-only files, then immediately re-verify with `git diff --check`.
-- [Detector Validation]: New integrity checks must be validated against real repo bytes before baselining, otherwise pure-LF files can be falsely classified as mixed EOL and pollute the baseline.
-- [Shell Dependency Guard]: Cross-platform validation entrypoints must not add new hard runtime dependencies unless the template explicitly requires them and the migration path is documented.
+- [Status Safety]: Ensure modular scan methods in `Scanner` prune ignored directories from `os.walk` to avoid scanning prohibited/large paths inappropriately.
+- [Test Assertion]: `DemoRunner.run()` returns 0 on success; smoke tests should assert 0 and verify finding details separately instead of asserting non-zero for findings.

 # GhostCheck
 
-**GhostCheck** is a CLI security scanner designed for AI-assisted development workflows. It addresses risks that traditional tools miss: hallucinated packages, leaked secrets in AI chat logs, and dangerous agent instruction configurations.
+## AI-Era Security Scanner for Developers
 
-## Features
+GhostCheck is a zero-dependency CLI security scanner designed to detect risks specific to AI-assisted development workflows.
 
-- 🦄 **Hallucination Detection**: Identify nonexistent packages on PyPI/npm.
-- 🔑 **Smart Secret Scanning**: Detect keys in AI logs with file-type-aware severity.
-- 🛡️ **Agent Rules Linter**: Scan `.agent/`, `.cursor/`, and `.github/` for risky rules.
-- 🚫 **Ignore Support**: Exclude paths via `.ghostcheckignore`.
-- 🚀 **Demo Mode**: Instant "wow" experience with `ghostcheck demo`.
+## Key Features
+
+- **Hallucination Detection**: Flags packages that don't exist on PyPI/npm or are suspiciously new.
+- **Secret Scanning**: Finds leaked API keys/tokens in AI chat logs and code with file-type-aware severity.
+- **Agent Rules Linter**: Audits `.agent`, `.cursor`, and other agent rules for dangerous permissions or commands.
+- **Zero Dependencies**: Pure Python implementation with no runtime dependencies.
 
 ## Installation
 
 ```bash
-git clone https://github.com/KbWen/security-tools.git
-cd security-tools
 pip install -e .
 ```
 
-## Quick Start
+## Usage
 
-```bash
-# Run a demo scan with sample vulnerabilities
-ghostcheck demo
+### Perform a Full Scan
 
-# Scan the current directory
+```bash
 ghostcheck scan .
+```
 
-# Check dependencies for hallucinations
+### Check Dependencies
+
+```bash
 ghostcheck check-deps requirements.txt
+ghostcheck check-deps package.json
 ```
 
-## Configuration
+### Scan for Secrets
 
-### .ghostcheckignore
+```bash
+ghostcheck check-secrets ./docs
+```
 
-Create a `.ghostcheckignore` file in your project root to exclude files:
+### Audit Agent Rules
 
-```text
-# Ignore log files
-*.log
-# Ignore dependency folder
-node_modules/
+```bash
+ghostcheck check-rules .agent/
+```
+
+### Interactive Demo
+
+```bash
+ghostcheck demo
 ```
 
+## Options
+
+- `--format [console|json]`: Specify output format.
+- `--severity [CRITICAL|HIGH|MEDIUM|LOW|INFO]`: Filter by minimum severity.
+- `--no-ignore`: Ignore `.ghostcheckignore` rules.
+- `--no-color`: Disable terminal colors.

 # GhostCheck
 
-**GhostCheck** 是一款專為 AI 協作開發工作流設計的 CLI 資安掃描工具。它能偵測傳統工具容易遺漏的風險：幻覺套件、AI 對話記錄中的金鑰洩漏，以及危險的 Agent 指令配置。
+## 專為 AI 輔助開發流程設計的安全性掃描工具
 
-## 功能特性
+GhostCheck 是一款零依賴 (Zero-dependency) 的命令列安全性掃描工具，旨在偵測 AI 模型產出中特有的風險。
 
-- 🦄 **幻覺偵測 (Hallucination)**：識別 PyPI/npm 上不存在的虛擬套件。
-- 🔑 **智慧金鑰掃描**：偵測 AI 日誌中的金鑰，並根據檔案類型自動調整嚴重度。
-- 🛡️ **Agent 規則檢查**：掃描 `.agent/`, `.cursor/`, `.github/` 中的危險指令。
-- 🚫 **忽略機制**：支援透過 `.ghostcheckignore` 排除檔案。
-- 🚀 **展示模式**：透過 `ghostcheck demo` 立即體驗掃描效果。
+## 核心功能
+
+- **幻覺套件偵測 (Hallucination Detection)**: 標記 PyPI/npm 上不存在或過於新穎、疑似為 AI 幻覺產出的套件。
+- **金鑰外洩掃描 (Secret Scanning)**: 在 AI 對話記錄（Chat Logs）或代碼中搜尋外洩的 API Key/Token，並根據檔案情境自動調整嚴重程度。
+- **Agent 規則檢查 (Agent Rules Linter)**: 審核 `.agent`、`.cursor` 等 Agent 規則檔，找出具風險的權限設定或危險指令。
+- **零運行時依賴**: 純 Python 實作，無需額外安裝執行環境套件。
 
 ## 安裝方式
 
 ```bash
-git clone https://github.com/KbWen/security-tools.git
-cd security-tools
 pip install -e .
