# Session Log: Create MicroSim Matcher Skill

**Date:** 2025-11-17
**Session Focus:** Create math-function-plotter-plotly skill and microsim-matcher skill, then apply matcher to all chapter details blocks

## Session Overview

This session involved three major tasks:
1. Creating the `math-function-plotter-plotly` skill for plotting mathematical functions with Plotly.js
2. Creating the `microsim-matcher` skill to intelligently match diagram specifications to appropriate MicroSim generators
3. Processing all 77 `<details>` blocks across 13 chapters to add MicroSim recommendations

---

## Part 1: Math Function Plotter Skill Creation

2. chartjs-generator - Any Chart.js chart types
3. map-generator - Interactive geographic maps with Leaflet.js
4. mermaid-generator - Flowcharts, process diagrams, decision trees
5. microsim-p5 - Interactive educational simulations with p5.js
6. timeline-generator - Chronological visualizations with vis-timeline.js
7. venn-diagram-generator - Venn diagrams with educational tooltips
8. vis-network - Interactive network graphs for learning graphs

### Recommended New Generators

**Top Priority:**
1. **Mathematical Function Plotter** - Plotly.js for function plots (STEM courses)
2. **Gantt Chart Generator** - Project/task scheduling
3. **Tree/Hierarchy Diagram Generator** - Organizational charts, taxonomies

**Medium Priority:**
4. Heatmap/Matrix Generator - Correlation matrices, confusion matrices
5. Sankey Diagram Generator - Flow visualization
6. Statistical Chart Generator - Box plots, histograms

### User Decision

User requested creation of `math-function-plotter-plotly` skill using the skill-creator skill.

**Step 2: Extract Key Characteristics**
- Temporal, geographic, mathematical, network, process, set-based, statistical, priority, custom
- Complexity level
- Educational features needed

**Step 3: Load MicroSim Generator Capabilities**
- Read matching-criteria.md

- Zoom, pan, filtering requirements
- Color-coded by phase

**Results:**
1. timeline-generator (98/100) - Perfect match
2. chartjs-generator (35/100) - Lacks timeline features
3. microsim-p5 (45/100) - Custom dev needed
4. mermaid-generator (30/100) - Too static

### Version Checking Solution

#### Problem Identified

User concern: `matching-criteria.md` will become outdated when:
- New MicroSim generators are added
- Existing generators get new features
- Scoring guidelines are refined

#### Solution Components

**1. Version Check Step (Step 0) in Workflow**
- Added as first step before analyzing specifications
- Compares local file timestamp to GitHub version

- Three modes:
  - Default: Detailed output with timestamps
  - `--quiet`: Exit code only (0=current, 1=outdated, 2=error)
  - `--update`: Auto-downloads latest version

**Usage:**
```bash
# Basic check
python skills/microsim-matcher/scripts/check-version.py

# CI/CD integration
python skills/microsim-matcher/scripts/check-version.py --quiet

# Auto-update
python skills/microsim-matcher/scripts/check-version.py --update
```

**GitHub API Endpoint:**
```
https://api.github.com/repos/dmccreary/claude-skills/commits?path=skills/microsim-matcher/references/matching-criteria.md
```

**3. Enhanced Documentation**

## Technical Details

### Scoring Methodology

All recommendations use this 100-point scale:

| Component | Points | Criteria |
|-----------|--------|----------|
| Data Type Match | 40 | Does data structure align with generator's expectations? |
| Interactivity Match | 25 | Do interaction needs match generator's capabilities? |
| Visual Style Match | 25 | Does desired visual output match generator's strengths? |
| Trigger Words | 10 | Contains keywords associated with this generator? |
| **Total** | **100** | |

### Score Interpretation

- **90-100**: Perfect match - Primary use case for this generator
- **70-89**: Strong match - Well-suited, minor limitations
- **50-69**: Moderate match - Could work but not optimal
- **30-49**: Weak match - Significant limitations or workarounds needed
- **0-29**: Poor match - Not recommended, use different generator

### Version Check Implementation

```python
# Get local file timestamp
local_date = os.path.getmtime(LOCAL_FILE_PATH)

# Query GitHub API
url = f"https://api.github.com/repos/{GITHUB_REPO}/commits?path={FILE_PATH}&page=1&per_page=1"
response = requests.get(url)
github_date = response.json()[0]["commit"]["committer"]["date"]

# Compare
if github_date > local_date:
    print("⚠️  WARNING: Reference File is Outdated")
```

## Conclusion

This session successfully created two new skills (math-function-plotter-plotly and microsim-matcher), implemented a robust version checking system, and systematically applied MicroSim recommendations to all 77 diagram specifications across the intelligent textbook chapters.

The microsim-matcher skill now provides intelligent, scored recommendations for choosing the appropriate MicroSim generator for any visualization specification, with built-in version control to ensure the matching criteria remain current as the repository evolves.

All chapter files now include clear guidance on which MicroSim generators to use for each planned visualization, creating a comprehensive roadmap for interactive content development.
