# Windsurf Common Errors

## Overview
Quick reference for the most common Windsurf IDE errors and their solutions. Covers Cascade failures, Supercomplete issues, indexing problems, and extension conflicts.

## Prerequisites
- Windsurf installed and previously working
- Access to Windsurf settings and logs

## Instructions

### Error 1: Cascade Not Responding

**Symptoms:** Cascade panel shows spinner indefinitely, no response to prompts.

**Solutions:**
1. Check internet connection -- Cascade requires cloud access
2. Check Windsurf status: https://status.windsurf.com
3. Check credit balance: Windsurf widget (status bar) > Account
4. Restart Cascade: Command Palette > "Cascade: Restart"
5. Restart Windsurf: Cmd/Ctrl+Shift+P > "Reload Window"

### Error 2: Supercomplete Not Showing Suggestions

**Symptoms:** No ghost text appears while typing.

**Solutions:**
1. Check if disabled: Click Windsurf widget (status bar) > verify autocomplete is ON
2. Check file type: Supercomplete may be disabled for certain languages
3. Check `.codeiumignore`: Current file might be excluded from indexing
4. Ensure not conflicting: Disable GitHub Copilot or TabNine if installed

```json
// Verify in settings.json
{
  "editor.inlineSuggest.enabled": true,
  "codeium.autocomplete.enable": true
}
```

### Error 3: Indexing Stuck or Slow

**Symptoms:** Status bar shows "Indexing..." for extended periods, Cascade lacks context.

**Solutions:**
1. Check workspace size: Windsurf struggles with 100K+ files without ignore rules
2. Create or update `.codeiumignore`:
```gitignore
node_modules/
.git/
dist/
build/
.next/
coverage/
vendor/
__pycache__/
*.min.js
*.bundle.js
*.map
```
3. Open a subdirectory instead of monorepo root
4. Command Palette > "Codeium: Reset Indexing"

### Error 4: Extension Conflicts

**Symptoms:** Duplicate suggestions, slow editor, features not working.

**Known conflicts:**
```
GitHub Copilot — conflicts with Supercomplete (disable one)
TabNine — conflicts with Supercomplete
Cody (Sourcegraph) — conflicts with Cascade
IntelliCode — may interfere with completions
```

**Fix:** Disable conflicting extensions:
```
Extensions sidebar > Search "copilot" > Disable
```

### Error 5: Cascade Writes to Wrong Files

**Symptoms:** Cascade modifies files you didn't intend.

**Solutions:**
1. Be specific in prompts: name exact file paths
2. Add constraints: "Don't modify any files except src/services/auth.ts"
3. Use `.windsurfignore` to protect sensitive directories
4. Review diffs before accepting -- use the Revert button per step
5. Always commit before Cascade sessions for safe rollback

### Error 6: "Model not available" or Credit Exhausted

**Symptoms:** "You've used all your credits" or specific model unavailable.

**Solutions:**
- Free plan: 25 credits/month. Switch to SWE-1 Lite (unlimited)
- Pro plan: 500 credits/month. Buy additional credits at windsurf.com/account
- Switch model: Use the model dropdown in Cascade to select a different model
- Check credit usage: Windsurf widget > Account > Usage

### Error 7: MCP Server Not Connecting

**Symptoms:** MCP tools not appearing in Cascade, "server disconnected" errors.

**Solutions:**
1. Verify MCP is enabled: Settings > Cascade > MCP > Enable
2. Check config file: `~/.codeium/windsurf/mcp_config.json`
3. Verify command exists: Run the MCP command manually in terminal
4. Check environment variables: MCP config supports `${VAR}` interpolation
5. Restart: Command Palette > "Cascade: Restart MCP Servers"

### Error 8: Cascade Loses Context Mid-Conversation

**Symptoms:** Cascade forgets what it was doing, makes contradictory changes.

**Solutions:**
1. Keep conversations focused: one task per Cascade session
2. Start a new conversation for new tasks (Cmd/Ctrl+L, then + icon)
3. Use @ mentions to re-inject context: `@src/services/auth.ts`
4. Convert key decisions to Memories: "Remember that we're using JWT, not sessions"
5. For long tasks, use Workflows instead of multi-turn conversations

## Error Handling
| Issue | Quick Fix | Root Cause |
|-------|-----------|------------|
| No AI features | Check auth in status bar | Token expired, re-sign-in |
| Cascade slow | Add `.codeiumignore` | Indexing too many files |
| Wrong suggestions | Update `.windsurfrules` | Missing project context |
| Preview broken | Close and re-open Preview | Dev server disconnected |
| Terminal errors | Cmd/Ctrl+Shift+. | Auto-debug via Cascade |

## Examples

### Quick Health Check
```bash
# Check if Windsurf is installed
windsurf --version

# Check Codeium auth state
ls ~/.codeium/
```

### Reset Everything
```
Command Palette (Cmd/Ctrl+Shift+P):
1. "Codeium: Reset Indexing"
2. "Cascade: Restart"
3. "Developer: Reload Window"
```
