# Wrong
claude mcp add fs -- npx -y @modelcontextprotocol/server-filesystem C:\Users\username\Documents

# Correct
claude mcp add fs -- npx -y @modelcontextprotocol/server-filesystem C:/Users/username/Documents
# or
claude mcp add fs -- npx -y @modelcontextprotocol/server-filesystem "C:\\Users\\username\\Documents"
```

#### MCP Debugging Techniques

**Enable Debug Mode:**

## Priority 4: Content Additions 📚

### 4.1 Security Best Practices - Do/Don't Format (30 min)

**What:** Clear visual Do/Don't examples.

**Where:** Section 8 Security

**Format:**
```markdown
### Security Pitfalls

**❌ Don't:**
- Use `--dangerously-skip-permissions` on production systems
- Hard-code secrets in commands/config files
- Grant overly broad permissions (`Bash(*)`)
- Run with elevated privileges unnecessarily

**✅ Do:**
- Store secrets in environment variables
- Start from minimal permissions and expand gradually
- Audit regularly with `claude config list`
- Isolate risky operations in containers/VMs
```

---

### 4.2 Performance Pitfalls Section (20 min)

**What:** Common performance mistakes.

**Format:**
```markdown
### Performance Pitfalls

**❌ Don't:**
- Load entire monorepo when you only need one package
- Max out thinking/turn budgets for simple tasks
- Ignore session cleanup (old sessions accumulate)
- Use `--ultrathink` for trivial edits

**✅ Do:**
- Use `--add-dir` for focused context
- Right-size with `--max-turns` and `MAX_THINKING_TOKENS`
- Set `cleanupPeriodDays` to prune old sessions
- Match thinking level to task complexity
```

---

### 4.3 Workflow Pitfalls Section (20 min)

**What:** Common workflow mistakes.

**Format:**
```markdown
### Workflow Pitfalls

**❌ Don't:**
- Skip project context (`CLAUDE.md`)
- Use vague prompts ("fix this", "check my code")
- Ignore errors in logs
- Automate workflows without testing first

**✅ Do:**
- Maintain and update `CLAUDE.md` regularly
- Be specific and goal-oriented in prompts
- Monitor via logs/OpenTelemetry as appropriate
- Test automation in safe environments first
- Review agent outputs before committing
```

---

### 4.4 DeepSeek Integration (15 min)

**What:** Alternative LLM provider integration.

**Where:** Section 11 "Third-Party Integrations"

**Content:**
```markdown
## 11.1 DeepSeek Integration

Use DeepSeek's Claude-compatible API as a cost-effective alternative.

### Setup

1. **Prerequisites:**
   - Claude Code installed: `npm install -g @anthropic-ai/claude-code`
   - DeepSeek API key from [platform.deepseek.com](https://platform.deepseek.com)

2. **Configure Environment:**
   ```bash
   export ANTHROPIC_BASE_URL=https://api.deepseek.com/anthropic
   export ANTHROPIC_AUTH_TOKEN=${YOUR_DEEPSEEK_API_KEY}
   export ANTHROPIC_MODEL=deepseek-chat
   export ANTHROPIC_SMALL_FAST_MODEL=deepseek-chat
   ```

3. **Launch Claude:**
   ```bash
   claude
   ```

### Cost Comparison

| Provider | Model | Cost per 1M tokens |
|----------|-------|-------------------|
| Anthropic | Sonnet 4 | ~$3.00 |
| DeepSeek | deepseek-chat | ~$0.14 |

**Savings: ~95% reduction**

### Limitations

- DeepSeek models have different capabilities than Claude
- Some advanced features may not work identically
- Performance/quality trade-offs exist

### Resources

- [DeepSeek API Documentation](https://api-docs.deepseek.com/guides/anthropic_api)
- [DeepSeek Platform](https://platform.deepseek.com)
```

## What NOT to Change

**Keep these strengths from our guide:**

1. **Learning Path Structure** - Junior → Senior → Power User progression
2. **Trinity Pattern** - Unique advanced workflow
3. **OpusPlan Mode** - Cost optimization strategy
4. **Context Management Zones** - Clear guidance on usage levels
5. **Maturity Model** - 5-level progression framework
6. **Agent-Based Task Delegation** - Advanced orchestration
7. **Skill Inheritance Model** - Reusable expertise
8. **Git Archaeology Pattern** - Unique debugging approach
9. **Narrative Style** - Pedagogical, not just reference
10. **Real-world Examples** - Production scenarios, not toy examples

---

## Conclusion

These recommendations balance:
- **Immediate impact** (quick wins) with **long-term value** (structural improvements)
- **Reference utility** (cheat sheets, tables) with **learning journey** (narrative)
- **Completeness** (troubleshooting) with **scannability** (collapsible sections)

**Core Philosophy:**
> zebbern's guide = comprehensive reference
> our guide = mastery journey
> **enhanced guide = both**

By selectively adopting zebbern's strengths while preserving our unique pedagogical approach, we create the definitive Claude Code resource.
