feat: initial companion repo for OpenClaw vs Claude Code article

40 files demonstrating every major OpenClaw capability using Claude Code:
- 3 agents (researcher, writer, reviewer)
- 3 skills (daily-briefing, slack-message, web-research)
- 2 security hooks (pre-tool-use blocker, post-tool-use logger)
- 10 self-contained examples with copy-paste prompts
- Complete feature map (20 capabilities, 11 full match, 7 different, 2 gap)
- Security docs including NemoClaw comparison
- Automation, messaging, browser, memory documentation

Zero dependencies. Clone and run.

+# Example 04: Browser Automation
+
+**Capability:** Claude Code can control a real browser via Playwright MCP, take
+screenshots, and extract structured data from live pages.
+
+**OpenClaw equivalent:** CDP/Playwright browser automation with screenshot and act commands.
+
+---
+
+## Prerequisites
+
+Playwright MCP must be enabled. Add this to `.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "playwright": {
+      "command": "npx",
+      "args": ["@playwright/mcp@latest"]
+    }
+  }
+}
+```
+
+This repo's `.mcp.json` already includes it. If Claude Code does not show
+Playwright tools at startup, run `npm install` to ensure the package is
+available, then restart.
+
+---
+
+## The Prompt
+
+```
+Navigate to https://news.ycombinator.com, take a screenshot of the current
+front page, and list the top 5 stories with their point counts and submitter
+names.
+
+Save the list to hacker-news-top5.md with the format:
+1. [title] - [points] points by [submitter]
+
+Include a note at the bottom with the timestamp of when you fetched this.
+```
+
+---
+
+## What Happens
+
+Claude Code will:
+
+1. Use the Playwright MCP `browser_navigate` tool to load the page
+2. Use `browser_screenshot` to capture the current state
+3. Use `browser_snapshot` or `browser_get_text` to extract story data
+4. Use Write to save the structured list to `hacker-news-top5.md`
+
+---
+
+## Why This Matters
+
+Browser automation handles pages that cannot be reached with WebFetch alone:
+JavaScript-rendered content, login-protected pages, and interactive workflows.
+
+OpenClaw bundles Playwright natively. Claude Code uses the same underlying
+engine via MCP. The setup takes two minutes; the capability is identical.
