+# Gotchas and Common Issues
+
+This document covers common pitfalls and issues you might encounter when working with the Babylon MCP server.
+
+## Alpine Linux / musl libc Compatibility
+
+### Issue: `ld-linux-x86-64.so.2` Error on Alpine
+
+**Symptom:**
+```
+Error: Error loading shared library ld-linux-x86-64.so.2: No such file or directory
+(needed by /root/babylon-mcp/node_modules/onnxruntime-node/bin/napi-v3/linux/x64//libonnxruntime.so.1.14.0)
+```
+
+**Cause:**
+Alpine Linux uses musl libc instead of glibc. The `onnxruntime-node` package requires glibc and won't work on Alpine without patching.
+
+**Solution:**
+Always run the Alpine setup script **after** `npm install` and **before** `npm run build`:
+
+```bash
+npm install           # Install dependencies
+npm run alpine:setup  # Patch transformers to use WASM backend
+npm run build         # Build TypeScript
+```
+
+**Why This Works:**
+The Alpine setup script patches `@xenova/transformers` to use the WASM backend (`onnxruntime-web`) instead of the native Node.js backend (`onnxruntime-node`), eliminating the glibc dependency.
+
+**Important:**
+- Run `npm run alpine:setup` every time you run `npm install` (it reinstalls unpatched packages)
+- The WASM backend is slightly slower but fully compatible with Alpine
+- This applies to production deployments on Alpine-based Docker containers or Alpine servers
+
+---
+
+## New Relic Integration
+
+### Issue: "New Relic requires that you name this application!"
+
+**Symptom:**
+```
+Error: New Relic requires that you name this application!
+Set app_name in your newrelic.js or newrelic.cjs file or set environment variable
+NEW_RELIC_APP_NAME. Not starting!
+```
+
+**Cause:**
+Environment variables from `.env` file are not being loaded before New Relic initializes.
+
+**Solution:**
+Use the `--env-file` flag when running the application:
+
+```bash
+# Development (already configured)
+npm run dev  # Uses: tsx watch --env-file=.env src/mcp/index.ts
+
+# Production
+node --env-file=.env dist/mcp/index.js
+```
+
+**For Alpine Services:**
+When running as a system service, ensure environment variables are sourced in the init script:
+
+```bash
+#!/sbin/openrc-run
+
+# Source environment file before starting
+[ -f /etc/babylon-mcp.env ] && . /etc/babylon-mcp.env
+
+command="/usr/bin/node"
+command_args="--env-file=/etc/babylon-mcp.env /path/to/babylon-mcp/dist/mcp/index.js"
+```
+
+**Required Environment Variables:**
+```bash
+NEW_RELIC_LICENSE_KEY=your_license_key_here
+NEW_RELIC_APP_NAME=babylon-mcp
+```
+
+---
+
+## Claude Code CLI Integration
+
+### Issue: Config File Approach Doesn't Work
+
+**Symptom:**
+Adding MCP server configuration to `~/.claude/config.json` doesn't make the server available in Claude Code.
+
+**Cause:**
+HTTP MCP server configuration in config files may not be fully supported or requires specific formatting that hasn't been determined yet.
+
+**Solution:**
+Use the CLI command approach instead:
+
+```bash
+# In Claude Code, connect directly with the URL
+/mcp http://localhost:4000/mcp
+```
+
+**Important:**
+- The MCP server must be running before connecting
+- Use `npm run dev` or `npm start` to start the server first
+- This is a known limitation being researched (see ROADMAP.md)
+
+---
+
+## ES Modules Configuration
+
+### Issue: Cannot Use `require()` with ES Modules
+
+**Cause:**
+The project uses ES modules (`"type": "module"` in package.json).
+
+**Solution:**
+- Use `import` instead of `require()`:
+  ```javascript
+  // ✗ Wrong
+  const newrelic = require('newrelic');
+
+  // ✓ Correct
+  import 'newrelic';
+  ```
+
+- For New Relic, the import must be the **first line** in `src/mcp/index.ts`:
+  ```typescript
+  import 'newrelic';  // Must be first!
+  import { BabylonMCPServer } from './server.js';
+  ```
+
+- Always include `.js` extensions in imports:
+  ```typescript
+  // ✗ Wrong
+  import { BabylonMCPServer } from './server';
+
+  // ✓ Correct
+  import { BabylonMCPServer } from './server.js';
+  ```
+
+---
+
+## Build and Deployment
+
+### Issue: TypeScript Compilation Errors After Dependency Updates
+
+**Solution:**
+Run type checking before building:
+
+```bash
+npm run typecheck  # Check for type errors
+npm run build      # Build if no errors
+```
+
+### Issue: Service Fails to Start After Code Changes
+
+**Checklist:**
+1. Did you rebuild after code changes?
+   ```bash
+   npm run build
+   ```
+
+2. On Alpine, did you run the Alpine setup script?
+   ```bash
+   npm run alpine:setup
+   npm run build
+   ```
+
+3. Are environment variables properly set?
+   ```bash
+   # Check if .env file exists
+   cat .env
+
+   # For services, check /etc/babylon-mcp.env
+   cat /etc/babylon-mcp.env
+   ```
+
+4. Restart the service:
+   ```bash
+   rc-service babylon-mcp restart
+   ```
+
+---
+
+## Data and Indexing
+
+### Issue: Search Returns No Results
+
+**Possible Causes:**
+1. Indexing hasn't been run
+2. Vector database is missing or corrupted
+3. Repositories haven't been cloned
+
+**Solution:**
+```bash
+# Clone repositories
+npm run clone:repos
+
+# Run full indexing
+npm run index:all
+
+# Or index components separately
+npm run index:docs
+npm run index:api
+npm run index:source
+```
+
+**Verify:**
+```bash
+# Check if data directory exists and has content
+ls -lh data/lancedb/
+ls -lh data/repositories/
+```
+
+---
+
+## Performance
+
+### Issue: First Search is Slow
+
+**Expected Behavior:**
+The first search after server start can take several seconds because:
+1. Vector embeddings model needs to be loaded into memory
+2. LanceDB tables need to be initialized
+3. Transformers.js initializes WASM runtime
+
+**Solution:**
+This is normal. Subsequent searches will be much faster (typically <500ms).
+
+### Issue: High Memory Usage
+
+**Cause:**
+The embedding model and vector database are loaded into memory.
+
+**Expected Memory Usage:**
+- Baseline: ~200-300MB
+- With model loaded: ~500-800MB
+- During indexing: ~1-2GB
+
+**Solution:**
+Ensure your server has at least 2GB RAM available, especially during indexing operations.
+
+---
+
+## Development
+
+### Issue: Tests Fail After Changes
+
+**Common Causes:**
+1. Mock implementations need updating
+2. Test coverage requirements not met
+3. TypeScript errors
+
+**Solution:**
+```bash
+# Run tests to see failures
+npm test
+
+# Run with coverage to see what's missing
+npm run test:coverage
+
+# Run type checking
+npm run typecheck
+```
+
+---
+
+## Security
+
+### Issue: Committing Secrets to Git
+
+**Prevention:**
+- Never commit `.env` files
+- Use `.env.example` for documentation
+- The `.gitignore` already excludes `.env`
+
+**If You Accidentally Commit Secrets:**
+1. Rotate/regenerate the secrets immediately (e.g., New Relic license key)
+2. Remove from git history using `git filter-branch` or BFG Repo-Cleaner
+3. Force push (if safe to do so)
+
+---
+
+## Port Conflicts
+
+### Issue: Port 4000 Already in Use
+
+**Symptom:**
+```
+Error: listen EADDRINUSE: address already in use :::4000
+```
+
+**Solution:**
+```bash
+# Find process using port 4000
+lsof -i :4000
+
+# Kill the process or use a different port
+# To use different port, modify server.start() call in src/mcp/index.ts
+```
+
+---
+
+## Quick Reference: Correct Build Order
+
+### Local Development (macOS/Linux with glibc)
+```bash
+npm install
+npm run build
+npm run dev
+```
+
+### Alpine Linux Production
+```bash
+npm install
+npm run alpine:setup  # Critical step!
+npm run build
+npm start
+```
+
+### After Pulling New Code
+```bash
+npm install           # Update dependencies
+npm run alpine:setup  # If on Alpine
+npm run build         # Rebuild TypeScript
+# Restart service or dev server
+```
+
+---
+
+## Getting Help
+
+If you encounter issues not covered here:
+
+1. Check the [README.md](README.md) for setup instructions
+2. Review the [ROADMAP.md](ROADMAP.md) for known limitations
+3. Check server logs for error messages
+4. Run diagnostic commands:
+   ```bash
+   npm run typecheck
+   npm test
+   node --version  # Should be >= 18
+   ```
+
+5. For Alpine-specific issues, verify you're using the WASM backend:
+   ```bash
+   grep "PATCHED FOR ALPINE" node_modules/@xenova/transformers/src/backends/onnx.js
+   ```

+### 1.6 Babylon Editor Integration ✅ **COMPLETED**
+**Goal**: Expand MCP server scope to support Babylon.js Editor tool usage and workflows
+
+#### Phase 1: Repository Setup & Exploration ✅ **COMPLETED**
+- [X] Clone https://github.com/BabylonJS/Editor.git independently (shallow clone)
+  - Location: data/repositories/Editor/
+  - Branch: master (note: uses 'master' not 'main')
+  - Independent from BabylonJS/Babylon.js (uses npm packages)
+- [X] Inspect repository structure and document findings:
+  - Documentation in `/website/src/app/documentation/` as Next.js **page.tsx files** (not markdown)
+  - Found 13 documentation pages (page.tsx files)
+  - Repository size: 751 MB (includes Electron build artifacts)
+  - Documentation site built with Next.js, content embedded in TSX components
+- [X] Catalog documentation types found:
+  - Editor tool usage guides (creating project, composing scene, managing assets)
+  - Editor-specific APIs (babylonjs-editor-tools decorators: @nodeFromScene, etc.)
+  - Script lifecycle documentation (onStart, onUpdate, onStop)
+  - Project templates (Next.js, SolidJS, Vanilla.js) in `/templates`
+  - Advanced features (texture compression, LOD, shadow optimization)
+
+#### Phase 2: Indexing Strategy Decision ✅ **COMPLETED**
+- [X] Evaluate documentation value for MCP users:
+  - Quantity: 13 documentation pages (TSX format, not markdown)
+  - Quality: High relevance - covers Editor workflows and Editor-only APIs
+  - Overlap: Minimal - Editor docs are distinct from core framework docs
+  - Uniqueness: Very high - decorators, lifecycle methods, Editor UI workflows are Editor-only
+- [X] Choose indexing approach based on findings:
+  - **Selected: Option A (Modified)** - Parse TSX files using TypeScript Compiler API
+  - Decided against web scraping to maintain source-of-truth from repository
+  - Built custom TSX parser to extract text from React components
+  - Rationale: Zero dependencies (uses built-in TypeScript), accurate parsing, maintainable
+- [X] Document decision and rationale: Using TypeScript Compiler API for TSX parsing
+
+#### Phase 3: Implementation ✅ **COMPLETED**
+- [X] Update repository-config.ts with Editor repository configuration
+- [X] Create TSX parser using TypeScript Compiler API (`src/search/tsx-parser.ts`)
+- [X] Extend DocumentParser to handle both `.md` and `.tsx` files
+- [X] Add Editor content to indexing pipeline (`editor-docs` source)
+- [X] Update LanceDB indexer to discover and process `page.tsx` files
+- [X] Test search quality with Editor-related queries - **Results: Working perfectly!**
+  - Tested queries: "onStart", "@nodeFromScene", "attaching scripts", "creating project"
+  - Editor docs appear in search results alongside core docs
+  - **Total indexed: 902 documents** (745 docs + 144 source + 13 editor)
+
+#### Phase 4: Editor-Specific MCP Tools (If valuable after Phase 3)
+- [ ] `search_babylon_editor_docs` - Search Editor documentation
+  - Input: query, category (workflow/scripting/assets/troubleshooting)
+  - Output: Ranked Editor-specific results
+- [ ] `get_babylon_editor_doc` - Retrieve full Editor documentation pages
+- [ ] `search_babylon_editor_api` - Search Editor APIs (decorators, lifecycle)
+- [ ] `get_babylon_template` - Retrieve project template files
+- [ ] Modify existing tools to support `source` parameter: "core" | "editor" | "both"
