feat: Add Sequential Thinking to Code Review + Frontend Validation

Enhanced code review and frontend validation with intelligent triggers:

Code Review Agent Enhancement:
- Added Sequential Thinking MCP integration for complex issues
- Triggers on 2+ rejections or 3+ critical issues
- New escalation format with root cause analysis
- Comprehensive solution strategies with trade-off evaluation
- Educational feedback to break rejection cycles
- Files: .claude/agents/code-review.md (+308 lines)
- Docs: CODE_REVIEW_ST_ENHANCEMENT.md, CODE_REVIEW_ST_TESTING.md

Frontend Design Skill Enhancement:
- Automatic invocation for ANY UI change
- Comprehensive validation checklist (200+ checkpoints)
- 8 validation categories (visual, interactive, responsive, a11y, etc.)
- 3 validation levels (quick, standard, comprehensive)
- Integration with code review workflow
- Files: .claude/skills/frontend-design/SKILL.md (+120 lines)
- Docs: UI_VALIDATION_CHECKLIST.md (462 lines), AUTOMATIC_VALIDATION_ENHANCEMENT.md (587 lines)

Settings Optimization:
- Repaired .claude/settings.local.json (fixed m365 pattern)
- Reduced permissions from 49 to 33 (33% reduction)
- Removed duplicates, sorted alphabetically
- Created SETTINGS_PERMISSIONS.md documentation

Checkpoint Command Enhancement:
- Dual checkpoint system (git + database)
- Saves session context to API for cross-machine recall
- Includes git metadata in database context
- Files: .claude/commands/checkpoint.md (+139 lines)

Decision Rationale:
- Sequential Thinking MCP breaks rejection cycles by identifying root causes
- Automatic frontend validation catches UI issues before code review
- Dual checkpoints enable complete project memory across machines
- Settings optimization improves maintainability

Total: 1,200+ lines of documentation and enhancements

## Next Steps
### 1. Add GitHub Token (Optional)
**If you want to use GitHub MCP:**
```bash
# Option A: Run setup script
bash scripts/setup-mcp-servers.sh
# Option B: Manual configuration
# Edit .mcp.json and add your token
```
**Generate Token:**
- Visit: https://github.com/settings/tokens
- Click "Generate new token (classic)"
- Select scopes: `repo`, `workflow`, `read:org`, `read:user`
- Copy token and add to `.mcp.json`
**Security:** Token is protected by .gitignore
---
### 2. Restart Claude Code
**IMPORTANT:** Configuration only loads on startup
**Steps:**
1. Completely quit Claude Code (close all windows)
2. Relaunch Claude Code
3. Open ClaudeTools project
4. MCP servers will now be available
---
### 3. Test MCP Servers
**Test 1: Sequential Thinking**
```
Use sequential thinking to break down the problem of
optimizing database queries in the ClaudeTools API.
```
**Expected:** Step-by-step analysis with structured thinking
---
**Test 2: Filesystem Access**
```
List all Python files in the api directory
```
**Expected:** Claude accesses filesystem and lists .py files
---
**Test 3: GitHub (if token configured)**
```
List my recent GitHub repositories
```
**Expected:** Claude queries GitHub API and shows repositories
---
### 4. Read Documentation
**For detailed information:**
- Complete guide: `MCP_SERVERS.md`
- Test results: `TEST_MCP_INSTALLATION.md`
- Configuration reference: `.mcp.json.example`
---
## Verification Checklist
**Before using MCP servers:**
- [ ] Node.js v24+ installed (verified: v24.11.0)
- [ ] .mcp.json exists in project root
- [ ] .mcp.json is gitignored (verified)
- [ ] GitHub token added (optional, for GitHub MCP)
- [ ] Claude Code restarted completely
- [ ] ClaudeTools project opened in Claude Code
**Test each server:**
- [ ] Sequential Thinking tested
- [ ] Filesystem tested
- [ ] GitHub tested (if token configured)
---
## Important Notes
### Security
**GitHub Token:**
- Never commit tokens to version control
- .mcp.json is automatically gitignored
- Use fine-grained tokens with minimal scopes
- Rotate tokens every 90 days
**Filesystem Access:**
- Currently limited to D:\ClaudeTools only
- Prevents accidental system file modifications
- Add more directories only if needed
---
### Gitea Integration
**GitHub MCP Limitation:**
- Designed for GitHub.com only
- Does NOT work with self-hosted Gitea
**For Gitea Support:**
- See "Future Gitea Integration" in MCP_SERVERS.md
- Options: Custom MCP server, adapter, or generic git MCP
- Requires additional development
---
### NPX Advantages
**No Manual Installation:**
- Packages downloaded on-demand
- Automatic version updates
- No global installations required
- Minimal disk space usage
---
## Troubleshooting
### MCP Servers Not Showing Up
**Solution:** Restart Claude Code completely
- Quit all windows
- Relaunch application
- Configuration loads on startup only
---
### GitHub MCP Authentication Failed
**Solutions:**
1. Verify token is in `.mcp.json` (not .mcp.json.example)
2. Check token scopes are correct
3. Test token with curl:
```bash
curl -H "Authorization: token YOUR_TOKEN" https://api.github.com/user
```
---
### Filesystem Access Denied
**Solutions:**
1. Verify path in `.mcp.json`: `D:\\ClaudeTools` (double backslashes)
2. Ensure directory exists
3. Add additional directories to args array if needed
---
## Quick Reference
### File Locations
**Configuration:**
- Active config: `D:\ClaudeTools\.mcp.json` (gitignored)
- Template: `D:\ClaudeTools\.mcp.json.example` (tracked)
