+</p>
+
+
+## Getting Started
+
+This package is available in the Node Package Repository.
+
+Add the plugin to your [OpenCode config](https://opencode.ai/docs/config/):
+
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "plugin": ["opencode-nodesecure"]
+}
+```
+
+That's it. OpenCode will automatically install the plugin on next run.
+
+## Updating
+
+> [!WARNING]
+> OpenCode does NOT auto-update plugins.
+
+To get the latest version, clear the cached plugin and let OpenCode reinstall it:
+
+```bash
+rm -rf ~/.cache/opencode/node_modules/opencode-nodesecure
+opencode
+```
+
+## Tools Provided
+
+| Tool        | Description                                                                 |
+| ----------- | --------------------------------------------------------------------------- |
+| `cwd_scanner` | Perform a security scan on the current working directory |
+| `remote_packages_scanner` | Perform a security scan on the given npm packages.         |
+
+## Usage
+
+Use natural language (e.g. i want to make a security scan on the current working directory, i want to perform a security scan on this dependency: react@19.0.0).

+  - Security warnings already flagged by the scanner
+  - Suspicious or obfuscated code patterns
+  - Unexpected outbound network calls

+
+RULES:
+  ${kReportFormat}
+
+  - Do not limit your analysis to the payload result, while the scanner is running, you should grep every js,ts,jsx,tsx files
+    in the current working directory and analyze them on your own, but wait the scanner payload to provide your conclusion.
+  - Keep the raw payload in your global context so that the user can ask you some questions after the analysis.
+  - If uncertain, set confidence to Low or Medium and explain why.
+  - Prefer payload fields when relevant.
+   - Otherwise, use code line ranges or short non - executable code excerpts.
+
+
+Constraints:
+  - All the files you grep, must be in the current working directory.
