# Session Summary: Standards & R-Development MCP Refactoring

**Date:** 2025-12-19 (Revised)
**Duration:** ~4 hours
**Focus:** Standards adoption + R-Development MCP consolidation

---

## ✅ What Was Accomplished

### 1. Standards Infrastructure (Complete) ✅

**Same as original session summary** - See SESSION-SUMMARY-2025-12-19.md

- 18,000+ lines of documentation
- Automated sync from zsh-configuration
- 12 standard documents (8 synced + 3 aiterm-specific + 1 README)
- Comprehensive ADHD-friendly templates

### 2. Command & MCP Refactoring Analysis (REVISED) ✅

**Original Analysis:**
- `COMMAND-MCP-REFACTORING-ANALYSIS.md` (1,283 lines)
- `REFACTORING-ACTION-PLAN.md` (554 lines)
- Identified 40% duplication, proposed 6-phase plan

**REVISED Analysis (Based on User Insight):**
- `COMMAND-MCP-REFACTORING-ANALYSIS-REVISED.md` (NEW)
- `REFACTORING-ACTION-PLAN-REVISED.md` (NEW)
- **Key Discovery:** 59% of commands (35/59) are R-ecosystem related!

---

## 🎯 Major Breakthrough: R-Development MCP Consolidation

### User Insight

> "Do we have R MCP server? Let's move all R-related to an MCP server."

### Discovery

The `statistical-research` MCP server already has comprehensive R development tools:
- `r_check`, `r_test`, `r_coverage`, `r_lint`, `r_document`
- Plus research tools (literature, citations, statistics)

**Realization:** It's not just "statistical-research" - it's a **comprehensive R development toolkit**!

### Revised Strategy

**Rename:** `statistical-research` → `r-development`

**Consolidate R Commands:**
- 2 code commands (ecosystem-health, rpkg-check) → MCP tools
- 8 research commands → MCP tools (already mostly there)
- 2 site commands (pkgdown build/deploy) → MCP tools

**Result:**
- r-development MCP: 14 → 20 tools (+43%)
- All R operations in one comprehensive toolkit
- Publishable to community

## 📊 Statistics - REVISED

### Files Created/Modified

| Type | Files | Lines |
|------|-------|-------|
| Standards docs (original) | 4 | ~10,000 |
| Standards templates (synced) | 12 | ~8,000 |
| Sync script | 1 | ~150 |
| **Original analysis** | 2 | 1,837 |
| **Revised analysis** | 2 | ~1,500 |
| Session summaries | 2 | ~800 |
| **Total** | **23** | **~22,287** |

### Key Metrics

| Metric | Before | After Refactoring | Change |
|--------|--------|-------------------|--------|
| Command files | 59 | 32 | -27 (-46%) |
| MCP servers | 3 | 4-5 | +1-2 |
| r-development tools | 14 | 20 | +6 (+43%) |
| R-related commands | 35 | 0 | All in MCP ✨ |
| Duplication | ~40% | <10% | -75% |

## 🎓 Key Insights

### Insight 1: R is the Core

**59% of commands are R-ecosystem related:**
- code/ - 2/8 R-specific (ecosystem-health, rpkg-check)
- research/ - 8/8 R-focused (statistical research)
- site/ - R package docs (pkgdown)
- teach/ - Statistical courses (R-heavy)
- write/ - Statistical papers

**Implication:** R-development MCP should be the foundation, not an afterthought.

### Insight 2: statistical-research Was Misnamed

The MCP already had:
- R package development tools (check, test, coverage, lint, document)
- Research tools (literature, citations, analysis planning)
- Statistical tools (simulation, hypothesis, power)

**Better name:** `r-development` - comprehensive R toolkit

### Insight 3: Commands = UX, MCP = Logic (Refined)

For R ecosystem:
- **Commands** = Quick discovery, help, navigation
- **r-development MCP** = All R operations (dev, research, docs)
- **Plugins** = Generic operations (git, github, code-review)

This creates clear mental model: "R stuff → r-development MCP"

## 📋 Recommended Next Steps

### Immediate (This Week)

**Option A: Phase 1 + Phase 2 Combo** ⭐ RECOMMENDED

**Phase 1 (1-2 hours):**
```bash
# Quick wins - archive duplicates
cp -r ~/.claude/commands ~/.claude/commands-backup-2025-12-19
mkdir -p ~/.claude/archive
# Archive 6 meta docs, 4 github commands, 3 git commands
# 59 → 46 files
```

**Phase 2 (8-10 hours, can split):**
```bash
# Rename MCP server
cd ~/projects/dev-tools/mcp-servers
mv statistical-research r-development

# Implement 6 new tools:
# - r_ecosystem_health (MediationVerse health check)
# - r_package_check_quick (quick R package check)
# - manuscript_section_writer (write paper sections)
# - reviewer_response_generator (respond to reviewers)
# - pkgdown_build (build R package docs)
# - pkgdown_deploy (deploy to GitHub Pages)

# Migrate 10 commands to MCP
# 46 → 36 files
```

**Result:**
- 59 → 36 files (-39%)
- r-development MCP: 20 comprehensive R tools
- All R operations consolidated

---

**Option B: Phase 1 Only First**
- Time: 1-2 hours
- Risk: Very Low
- Impact: Immediate cleanup
- Then evaluate before Phase 2

---

**Option C: Jump to Phase 2**
- Time: 8-10 hours
- Risk: Medium
- Impact: Maximum value (R consolidation)
- Can skip Phase 1 if confident

---

### Short-term (Next 2 Weeks)

**After Phase 1+2:**

**Phase 3: Teaching MCP Server** (Weeks 3-4)
- Create teaching-toolkit MCP (10 tools)
- SQLite question bank with:
  - Bloom taxonomy
  - Usage tracking
  - Difficulty ratings
- Canvas API integration
- Migrate 9 teaching commands
- 36 → 27 files

---

### Medium-term (Month 2)

**Phase 4-6: Optional Refinements**
- Code quality delegation to plugins
- Site automation for non-R projects
- Optional workflow-manager MCP

**Final result:** 20-23 files, 4-5 MCP servers
