# Custom Code Management

Add, review, and manage inline custom scripts on a Webflow site — analytics, tracking pixels, chat widgets, or any custom JavaScript.

## Important Note

**ALWAYS use Webflow MCP tools for all operations:**
- Use Webflow MCP's `webflow_guide_tool` to get best practices **before any other tool call**
- Use Webflow MCP's `data_sites_tool` with action `list_sites` to identify available sites
- Use Webflow MCP's `data_scripts_tool` with action `list_registered_scripts` to list all registered scripts
- Use Webflow MCP's `data_scripts_tool` with action `list_applied_scripts` to list scripts applied to pages
- Use Webflow MCP's `data_scripts_tool` with action `add_inline_site_script` to register a new inline script
- Use Webflow MCP's `data_scripts_tool` with action `delete_all_site_scripts` to remove ALL site scripts (no selective delete)
- Use Webflow MCP's `data_scripts_tool` with action `get_page_script` to get custom code for a specific page
- Use Webflow MCP's `data_scripts_tool` with action `upsert_page_script` to add or update page-level custom code
- Use Webflow MCP's `data_scripts_tool` with action `delete_all_page_scripts` to remove all custom code from a page
- All tool calls must include the required `context` parameter (15-25 words, third-person perspective)

## Instructions

### Phase 1: Discovery
1. **Call `webflow_guide_tool` first** — always the first MCP tool call
2. **Get the site**: Use `data_sites_tool` with action `list_sites`. If only one site, use it automatically.

### Phase 2: Analysis
3. **List scripts**: Call `list_registered_scripts` and `list_applied_scripts` in parallel
4. **Check page-level scripts** (if relevant): Use `get_page_script` for specific pages
5. **Present findings**: Name, version, location (header/footer), registration vs application status

### Phase 3: Planning & Confirmation
Before any mutation, present the plan and require explicit confirmation:
- Adding scripts: user must type **"add"**
- Removing ALL site scripts: user must type **"delete all"** (warn: no selective delete)
- Page-level changes: user must type **"update"**

### Phase 4: Execution
6. **Add site script**: `add_inline_site_script` with displayName, sourceCode, version, location, canCopy
7. **Remove all site scripts**: `delete_all_site_scripts`
8. **Add/update page script**: `upsert_page_script`
9. **Remove page scripts**: `delete_all_page_scripts`

### Phase 5: Verification
10. Re-list scripts to confirm success
11. Report what changed (name, location, version, char count)
12. Remind user to publish — suggest using `safe-publish` skill

## Examples

### Example 1: View scripts
**User:** "What scripts are on my site?"
1. `webflow_guide_tool` → `data_sites_tool` → `list_registered_scripts` + `list_applied_scripts` in parallel
2. Present summary of all scripts

### Example 2: Add Google Tag Manager
**User:** "Add GTM to my site"
1. `webflow_guide_tool` → `data_sites_tool` → ask for GTM container ID
2. Preview script, require "add" → `add_inline_site_script` (header, version "1.0.0")
3. Verify and remind to publish

### Example 3: Remove all scripts
**User:** "Remove all scripts"
1. `webflow_guide_tool` → `data_sites_tool` → list current scripts
2. Warn: removes ALL scripts. Require "delete all" → `delete_all_site_scripts`
3. Verify and remind to publish

### Example 4: Page-specific tracking
**User:** "Add conversion tracking to my thank-you page"
1. `webflow_guide_tool` → `data_sites_tool` → `get_page_script` to check existing
2. Preview, require "update" → `upsert_page_script`
3. Verify and remind to publish

## Guidelines

- **`webflow_guide_tool` always first** — before any other MCP tool
- **No `<script>` tags** — Webflow adds them automatically
- **Max 10,000 characters** per script; `displayName` + `version` must be unique
- **Site-level** scripts (`add_inline_site_script`) apply to all pages; **page-level** scripts (`upsert_page_script`) apply to one page
- **No selective delete** — `delete_all_site_scripts` removes everything; always list scripts first so user knows what will be lost
- **Hosted/external scripts** not available via MCP — inline only
- Recommend **header** for analytics (GA, GTM); **footer** for chat widgets and non-critical scripts
- If `displayName + version` exists, suggest incrementing the version
- Always remind users to **publish** after changes
