Install and run
Setup complexity: low.
clawhub skill install kn70sq5y624xbj69rq2k62bm7n80k01y:web-monitor- Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
- Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

--- name: web-monitor description: Monitor web pages for content changes and get alerts. Track URLs, detect updates, view diffs. Use when asked to watch a website, track changes on a page, monitor for new posts/content, set up page change alerts, or check if a site has been updated. Supports CSS selectors for targeted monitoring. --- # Web Monitor Track web pages for changes. Stores snapshots, computes diffs, supports CSS selectors. ## Quick Start ```bash # Add a URL to watch uv run --with beautifulsoup4 python scripts/monitor.py add "https://example.com" --name "Example" # Add with CSS selector (monitor specific section) uv run --with beautifulsoup4 python scripts/monitor.py add "https://example.com/pricing" -n "Pricing" -s ".pricing-table" # Check all watched URLs for changes uv run --with beautifulsoup4 python scripts/monitor.py check # Check one specific URL uv run --with beautifulsoup4 python scripts/monitor.py check "Example" # List watched URLs uv run --with beautifulsoup4 python scripts/monitor.py list # View last diff uv run --with beautifulsoup4 python scripts/monitor.py diff "Example" # View current snapshot uv run --with beautifulsoup4 python scripts/monitor.py snapshot "Example" --lines 50 # Remove uv run --with beautifulsoup4 python scripts/monitor.py remove "Example" ``` ## Commands | Command | Args | Description | |---------|------|-------------| | `add` | `<url> [-n name] [-s selector]` | Add URL to watch, take initial snapshot | | `remove` | `<url-or-name>` | Stop watching a URL | | `list` | `[-f json]` | List all watched URLs with stats | | `check` | `[url-or-name] [-f json]` | Check for changes (all or one) | | `diff` | `<url-or-name>` | Show last recorded diff | | `snapshot` | `<url-or-name> [-l lines]` | Show current snapshot | ## Output Symbols - 🔔 CHANGED — page content changed (shows diff preview) - ✅ No changes - 📸 Initial snapshot taken - ❌ Error fetching ## Data Stored in `~/.web-monitor/` (override with `WEB_MONITOR_DIR` env var): - `watches.json` — watch list config - `snapshots/` — stored page content + diffs ## Tips - Use `--selector` to monitor specific elements (prices, article lists, etc.) - Use `--format json` for programmatic checking (heartbeat integration) - CSS selectors require beautifulsoup4 (included via `--with` flag) - Text is normalized to reduce noise from timestamps, whitespace, ads
