## 10.4 Troubleshooting
### Quick Diagnostic Guide
Use this symptom-based guide for rapid issue identification and resolution:
| Symptom | Likely Cause | Quick Fix | Prevention |
|---------|--------------|-----------|------------|
| "Context too long" error | Session accumulated too much context | `/compact` first, then `/clear` if needed | Compact regularly at 70% |
| Slow/delayed responses | High context usage (>75%) | Check `/status`, run `/compact` | Monitor context with `/status` |
| "Rate limit exceeded" | API throttling from frequent requests | Wait 2 minutes, use `--model haiku` for simple tasks | Batch operations, use `/compact` |
| Claude forgets instructions | Context overflow, CLAUDE.md lost | Create checkpoint, `/clear`, reload CLAUDE.md | Keep CLAUDE.md concise (<500 lines) |
| MCP server not connecting | Server crashed or config error | `claude mcp list`, check paths, restart server | Test servers after config changes |
| Permission prompts every time | Tool not in `allowedTools` | Add pattern to `settings.json` allowedTools | Use wildcards: `Bash(git:*)` |
| Changes not taking effect | Cached configuration | Restart Claude Code session | Use `/exit` before config changes |
| Session won't resume | Corrupted session file | Start fresh with `/clear` | Exit cleanly with `/exit` or `Ctrl+D` |
**Quick Diagnosis Flow:**
1. Check context: `/status` → If >70%, run `/compact`
2. Check connectivity: Try simple command → If fails, check network
3. Check configuration: `claude mcp list` → Verify MCP servers
4. Check permissions: Review error message → Add to allowedTools if needed
5. Still failing: `claude doctor` → Verify system health
### Common Issues Reference
| Symptom | Cause | Solution |
|---------|-------|----------|
| "Context too long" | Used 100% context | `/clear` or `/compact` |
