### 2. Analyzed Competitive Landscape 🔍

**Competitor:** rahulsethi/SAPDatasphereMCP
- 11 tools (proof of concept, v0.1.0)
- Basic FastMCP + httpx architecture

**Our Position:**
- 42 tools → 44 tools (after v1.0.3)
- Enterprise-grade, production-ready
- 98% real data integration
- **300% competitive advantage** (44 vs 11)

**Decision Made:** Implement 2 high-value tools (Option B)
- ✅ `find_assets_by_column` - Data lineage discovery
- ✅ `analyze_column_distribution` - Statistical analysis
- ❌ `profile_asset_schema` - SKIPPED (redundant)

---

### 3. Prepared v1.0.3 Implementation 📋

**Version Bump:** 1.0.2 → 1.0.3
- ✅ pyproject.toml updated
- ✅ setup.py updated
- ✅ Tool count: 44 tools
- ✅ Description updated

**Planning Documents Created:**
1. **V1.0.3_IMPLEMENTATION_PLAN.md** - Detailed 6-8 hour plan
2. **COMPETITIVE_ANALYSIS_IMPLEMENTATION_GUIDE.md** - Kiro's specs
3. **V1.0.3_READY_TO_IMPLEMENT.md** - Status document
4. **NEXT_SESSION_START_HERE.md** - Comprehensive next session guide
5. **This file** - Session summary

## What's Pending for Next Session ⏳

### v1.0.3 Implementation (~6-8 hours)

**2 New Tools to Implement:**

#### 1. find_assets_by_column
- Find assets containing specific column names
- Use cases: Data lineage, impact analysis, dataset discovery
- Uses existing catalog APIs + schema checking
- Both mock and real API modes

#### 2. analyze_column_distribution
- Statistical analysis of column data
- Use cases: Data quality assessment, profiling, outlier detection
- Uses existing execute_query tool
- Calculates stats: null rates, distinct counts, percentiles, outliers

**Implementation Tasks:**
1. Add tool descriptions (~150 lines)
2. Implement handlers (~200 lines)
3. Add authorization/validation (~35 lines)
4. Test both tools (1-2 hours)
5. Update documentation (1 hour)
6. Build and publish to PyPI (30 min)

## Key Decisions Made Today 🎯

1. **Smart Enhancements Over Bulk Implementation**
   - v1.0.2: Enhanced 2 existing tools (3 hours) ✅

2. **Competitive Response Strategy**
   - Add 2 high-value unique tools (Option B) ✅
   - Skip redundant tool (profile_asset_schema) ✅
   - Maintain quality-first approach ✅

3. **Release Strategy**
   - Combine v1.0.2 + v1.0.3 in single release ✅
   - Publish as v1.0.3 with 44 tools ✅
   - Better competitive story (300% vs 280%) ✅

4. **Implementation Timing**
   - Continue in next fresh session ✅
   - Ensure quality and completeness ✅
   - Avoid rushing with low context ✅
