+# Checkmk SwissKnife
+
+A [Tampermonkey](https://www.tampermonkey.net/) userscript that enhances the Checkmk 2.3.x web interface with quality-of-life improvements for WATO configuration and monitoring views.
+
+## Installation
+
+1. Install the [Tampermonkey](https://www.tampermonkey.net/) browser extension.
+2. Click **Install script** below (or open the raw `.user.js` URL):
+
+   [**Install Checkmk SwissKnife**](https://luigidacunto.com/scripts/checkmk-swissknife/user_script/checkmk_swissknife.user.js)
+
+3. Tampermonkey will detect the `@downloadURL` and prompt for updates automatically.
+
+**Compatibility:** Checkmk 2.3.x · Chrome · Firefox · Edge
+
+## Features
+
+### Folder Path Search
+Replaces the default WATO folder dropdown with a searchable overlay. Type any segment of the folder path to filter — separators `>`, `›`, and `/` are treated as equivalent.
+
+Applies to: rule condition editor (`explicit_conditions_p_folder_path`) and monitoring view folder filter (`wato_folder`).
+
+---
+
+### Accordion Badge Counts
+Displays inline counters in each accordion section header on host edit pages:
+
+| Badge | Meaning |
+|-------|---------|
+| **orange `(N)`** | N checkboxes enabled in this section |
+| **blue `↑N`** | N values inherited from a parent folder |
+| **red `≠N`** | N values that differ from the folder default *(bulk edit only)* |
+
+Applies to: `edit_host`, `bulkedit`, `editfolder`.
+
+---
+
+### Ineffective Rule Highlight
+Replaces the low-visibility hyphen icon on ineffective rules with a prominent **`⚠ ineffective`** badge and adds an amber left border to the row.
+
+Applies to: `mode=edit_ruleset`.
+
+---
+
+### Rule Match Status Highlight
+When a ruleset is opened in context (URL contains `host=` and/or `service=`), colors each rule row:
+
+- **Green + `✓ match`** — rule applies to the given host/service
+- **Dimmed + `✗ no match`** — rule does not apply
+
+Applies to: `mode=edit_ruleset` with host/service context.
+
+---
+
+### Ruleset Filter Toggle
+After match/ineffective highlighting runs, a **"Relevant only"** button appears above the rule list. Clicking it hides all non-highlighted rows and empty folders, leaving only the rules that matter for the current context.
+
+Applies to: `mode=edit_ruleset` (when at least one highlighted row exists).
+
+---
+
+### Inventory Buttons on Monitoring Views
+Adds three icon buttons before each hostname in monitoring view tables:
+
+| Button | Action |
+|--------|--------|
+| Screen icon | Opens **Service Discovery** for the host in a new tab |
+| Clipboard icon (blue) | Copies the full FQDN to clipboard |
+| Clipboard icon (purple) | Copies the short hostname (first label) to clipboard |
+
+Applies to: `view.py` host and service views.
+
+---
+
+### Monitor Button on WATO Folder Pages
+Adds a green eye icon next to each active (non-disabled) host in WATO folder listings, opening the host's monitoring view in a new tab. A summary badge on the section header shows monitored vs disabled host counts.
+
+Applies to: `wato.py?mode=folder`.
+
+---
+
+### "Configure in WATO" Menu
+Adds a paginated dropdown + **Open** button to the monitoring view menu bar. Selecting a page and clicking **Open** launches WATO in a new tab with exactly those hosts pre-filtered via regex search — ready for bulk configuration.
+
+- Up to 50 hosts per page (keeps URLs within safe length limits)
+- Deduplicates hostnames automatically (useful on service views where hosts repeat)
+- Only visible for users with WATO configuration access
+
+Applies to: `view.py` (admin/configuration role required).
+
+## How it works
+
+The script injects enhancements at page load and re-applies them on SPA navigation (Checkmk reloads content inside an `<iframe>` without a full page reload). Each feature is independent — a feature that does not apply to the current page does nothing and stops polling.
+
+## License
+
+MIT — see [LICENSE](LICENSE) if present, otherwise consider it free for any use.
