# Skill Consolidation Session Log

**Date:** December 10, 2025
**Project:** Claude Code Skills
**Goal:** Consolidate 36+ skills to under 30 (Claude Code hard limit)

---

## Session Summary

Discovered that Claude Code has a hard-coded limit of 30 skills. With 36+ skills currently symlinked, some were being silently ignored. Designed a consolidation plan using "meta-skill dispatchers" to reduce count from 36 to 19 skills.

---

## Phase 1: Discovery & Analysis

### Problem Identification

User reported that Claude Code was ignoring some skills. Investigation revealed:
- Claude Code enforces a **maximum of 30 skills**
- Extra skills are silently ignored (no error message)
- Which skills get ignored is non-deterministic

### Current Skill Inventory

Explored `~/.claude/skills/` directory and found:

**Storage Architecture:**
- 29 symlinks → `/Users/dan/Documents/ws/claude-skills/skills/`
- 6 local skills (stored directly, not symlinked)
- 1 archive file (causal-loop-microsim-generator.zip)

**Skill Categories Identified:**

| Category | Count | Examples |
|----------|-------|----------|
| Content Generation | 14 | chapter-content-generator, quiz-generator, glossary-generator |
| MicroSim Visualization | 13 | microsim-p5, chartjs-generator, timeline-generator |
| Installation/Setup | 3 | install-mkdocs-template, install-skill-tracker |
| Utilities | 4 | microsim-standardization, microsim-screen-capture |
| Specialized | 2 | moving-rainbow, skill-creator |

### Skill Size Analysis

Largest skills by file size:
- learning-graph-generator: 112K
- chartjs-generator: 96K
- microsim-p5: 72K
- install-skill-tracker: 76K
- readme-generator: 68K
- venn-diagram-generator: 68K

---

## Phase 2: Requirements Gathering

### User Preferences (via AskUserQuestion)

1. **Goal:** Both reduce count AND optimize token usage
2. **Routing approach:** Meta-skill dispatcher (super-skills that route internally)
3. **Priority:** Keep content generators as separate skills

### Design Constraints

- Must stay under 30 skills
- Preserve 100% of original functionality
- Allow rollback if issues arise
- Optimize token usage for common operations

---

## Phase 3: Consolidation Design

### Meta-Skill Architecture

A **meta-skill dispatcher** is a single skill that:
1. Has a concise SKILL.md entry point with routing logic
2. Stores sub-skill details in `references/` subdirectory
3. Loads only relevant guide file on-demand
4. Uses keyword matching for routing

### Consolidation Groups

**Group 1: microsim-generator** (13 → 1)
- microsim-p5, chartjs-generator, bubble-chart-generator
- timeline-generator, map-generator, venn-diagram-generator
- mermaid-generator, math-function-plotter-plotly, vis-network
- causal-loop-microsim-generator, comparison-table-generator
- celebration-animation-generator, microsim-matcher

**Group 2: installer** (3 → 1)
- install-mkdocs-template
- install-learning-graph-viewer
- install-skill-tracker

**Group 3: microsim-utils** (4 → 1)
- microsim-standardization
- microsim-screen-capture
- microsim-add-icons
- microsims-index-generator

### Final Count

| Category | Before | After |
|----------|--------|-------|
| MicroSim generators | 13 | 1 |
| Installation skills | 3 | 1 |
| Utility skills | 4 | 1 |
| Content generators | 14 | 14 |
| Specialized | 2 | 2 |
| **TOTAL** | **36** | **19** |

## Phase 4: Routing Table Design

### microsim-generator Routing

| Trigger Keywords | Guide File | Library |
|------------------|------------|---------|
| timeline, dates, chronological, events, history | timeline-guide.md | vis-timeline |
| map, geographic, coordinates, latitude | map-guide.md | Leaflet.js |
| function, f(x), equation, calculus | plotly-guide.md | Plotly.js |
| network, nodes, edges, dependencies | vis-network-guide.md | vis-network |
| flowchart, workflow, process, UML | mermaid-guide.md | Mermaid.js |
| venn, sets, overlap, intersection | venn-guide.md | Custom |
| chart, bar, line, pie, statistics | chartjs-guide.md | Chart.js |
| bubble, priority, matrix, quadrant | bubble-guide.md | Chart.js |
| causal, feedback, loop, systems | causal-loop-guide.md | vis-network |
| comparison, table, ratings, stars | comparison-table-guide.md | Custom |
| animation, celebration, particles | celebration-guide.md | p5.js |
| custom, simulation, physics, p5.js | p5-guide.md | p5.js |

---

## Phase 5: Token Optimization Analysis

### Before Consolidation
- Skill listing exposure: ~1,500K tokens potential
- MicroSim request: Full SKILL.md loaded (~50-100K)

### After Consolidation
- Skill listing exposure: ~800K tokens
- MicroSim request: Routing (~15K) + Guide (~20-30K) = ~35-45K

**Estimated savings: 40-60% per MicroSim generation request**

### Final Results

| Metric | Before | After |
|--------|--------|-------|
| Total skills in ~/.claude/skills/ | 36+ | **16** |
| Skills over limit | 6+ | **0** |
| Headroom for new skills | 0 | **14** |

### Files Created

**Meta-skills:**
- `/Users/dan/Documents/ws/claude-skills/skills/microsim-generator/SKILL.md`
- `/Users/dan/Documents/ws/claude-skills/skills/installer/SKILL.md`
- `/Users/dan/Documents/ws/claude-skills/skills/microsim-utils/SKILL.md`

**Guide files:** 20 total (13 + 3 + 4)

**Archived skills:** 20 (preserved in `/skills/archived/`)

---

## Rollback Plan

If issues arise:
1. Original skills preserved in `archived/` directory
2. Remove meta-skill symlinks
3. Restore original symlinks
4. Restart Claude Code

---

## Key Insights

1. **Silent failure is problematic** - Claude Code should warn when skills exceed limit
2. **Meta-skill pattern** - Effective for consolidating related functionality
3. **On-demand loading** - Significant token savings by loading guides only when needed
4. **Preserve originals** - Archive don't delete for easy rollback
