+# RTK Plugin for OpenClaw
+
+Transparently rewrites shell commands executed via OpenClaw's `exec` tool to their RTK equivalents, achieving 60-90% LLM token savings.
+
+This is the OpenClaw equivalent of the Claude Code hooks in `hooks/rtk-rewrite.sh`.
+
+## How it works
+
+The plugin registers a `before_tool_call` hook that intercepts `exec` tool calls. When the agent runs a command like `git status`, the plugin delegates to `rtk rewrite` which returns the optimized command (e.g. `rtk git status`). The compressed output enters the agent's context window, saving tokens.
+
+All rewrite logic lives in RTK itself (`rtk rewrite`). This plugin is a thin delegate -- when new filters are added to RTK, the plugin picks them up automatically with zero changes.
+
+## Installation
+
+### Prerequisites
+
+RTK must be installed and available in `$PATH`:
+
+```bash
+brew install rtk
+# or
+curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh
+```
+
+### Install the plugin
+
+```bash
+# Copy the plugin to OpenClaw's extensions directory
+mkdir -p ~/.openclaw/extensions/rtk-rewrite
+cp openclaw/index.ts openclaw/openclaw.plugin.json ~/.openclaw/extensions/rtk-rewrite/
+
+# Restart the gateway
+openclaw gateway restart
+```
+
+### Or install via OpenClaw CLI
+
+```bash
+openclaw plugins install ./openclaw
+```
+
+## Configuration
+
+In `openclaw.json`:
+
+```json5
+{
+  plugins: {
+    entries: {
+      "rtk-rewrite": {
+        enabled: true,
+        config: {
+          enabled: true,    // Toggle rewriting on/off
+          verbose: false     // Log rewrites to console
+        }
+      }
+    }
+  }
+}
+```
+
+## What gets rewritten
+
+Everything that `rtk rewrite` supports (30+ commands). See the [full command list](https://github.com/rtk-ai/rtk#commands).
+
+## What's NOT rewritten
+
+Handled by `rtk rewrite` guards:
+- Commands already using `rtk`
+- Piped commands (`|`, `&&`, `;`)
+- Heredocs (`<<`)
+- Commands without an RTK filter
+
+## Measured savings
+
+| Command | Token savings |
+|---------|--------------|
+| `git log --stat` | 87% |
+| `ls -la` | 78% |
+| `git status` | 66% |
+| `grep` (single file) | 52% |
+| `find -name` | 48% |
+
+## License
+
+MIT -- same as RTK.
