name: doc-splitter description: Split large documentation (10K+ pages) into focused sub-skills with intelligent routing. Use for massive doc sites like Godot, AWS, or MSDN. Use when relevant to the task.

Documentation Splitter Skill

Purpose

Single responsibility: Split large documentation sites into multiple focused sub-skills with an optional router skill for intelligent navigation. (BP-4)

Grounding Checkpoint (Archetype 1 Mitigation)

Before executing, VERIFY:

• Total page count is known (run estimation first)
• Documentation categories are identifiable
• Target skill size determined (default: 5,000 pages per skill)
• Router strategy selected (category, size, or hybrid)

DO NOT split without understanding documentation structure.

Uncertainty Escalation (Archetype 2 Mitigation)

ASK USER instead of guessing when:

• Category boundaries unclear
• Optimal skill size uncertain for target use case
• Cross-references between sections complicate splitting
• Router vs flat structure decision needed

NEVER arbitrarily split - seek user guidance on boundaries.

Context Scope (Archetype 3 Mitigation)

Context Type	Included	Excluded
RELEVANT	Doc structure, categories, page counts	Actual page content
PERIPHERAL	Similar large doc examples	Other documentation
DISTRACTOR	Content quality concerns	Individual page issues

Size Guidelines

Documentation Size	Recommendation	Strategy
< 5,000 pages	One skill	No splitting
5,000 - 10,000 pages	Consider splitting	Category-based
10,000 - 30,000 pages	Recommended	Router + Categories
30,000+ pages	Strongly recommended	Router + Categories

Workflow Steps

Step 1: Estimate Documentation Size (Grounding)

# Quick estimation with skill-seekers
skill-seekers estimate configs/large-docs.json

# Output:
# 📊 ESTIMATION RESULTS
# ✅ Pages Discovered: 28,450
# 📈 Estimated Total: 32,000
# ⏱️  Time Elapsed: 2.1 minutes
# 💡 Recommended: Split into 6-7 sub-skills

Step 2: Analyze Category Structure

# Identify natural category boundaries
skill-seekers analyze --config configs/large-docs.json --categories

# Output:
# Categories detected:
# - scripting: 8,200 pages
# - 2d: 5,400 pages
# - 3d: 9,100 pages
# - physics: 4,300 pages
# - networking: 2,800 pages
# - editor: 2,200 pages

Step 3: Choose Split Strategy

Strategy	Best For	Description
category	Clear topic divisions	Split by documentation sections
size	Uniform distribution	Split every N pages
router	User navigation	Hub skill + specialized sub-skills
hybrid	Complex docs	Categories + size limits per category

Step 4: Execute Split

Option A: With skill-seekers

# Category-based split
skill-seekers split --config configs/godot.json --strategy category

# Router-based split (recommended for large docs)
skill-seekers split --config configs/godot.json --strategy router

# Size-based split
skill-seekers split --config configs/godot.json --strategy size --pages-per-skill 5000

Option B: Manual split configuration

{
  "name": "godot",
  "max_pages": 40000,
  "split_strategy": "router",
  "split_config": {
    "target_pages_per_skill": 5000,
    "create_router": true,
    "categories": {
      "scripting": {
        "patterns": ["/scripting/", "/gdscript/", "/c_sharp/"],
        "max_pages": 8000
      },
      "2d": {
        "patterns": ["/2d/", "/sprite/", "/tilemap/"],
        "max_pages": 6000
      },
      "3d": {
        "patterns": ["/3d/", "/mesh/", "/spatial/"],
        "max_pages": 10000
      },
      "physics": {
        "patterns": ["/physics/", "/collision/", "/rigidbody/"],
        "max_pages": 5000
      }
    }
  }
}

Step 5: Scrape Sub-Skills

# Scrape all sub-skills in parallel
for config in configs/godot-*.json; do
  skill-seekers scrape --config $config &
done
wait

# Or sequentially with progress
for config in configs/godot-*.json; do
  echo "Processing: $config"
  skill-seekers scrape --config $config
done

Step 6: Generate Router Skill

# Auto-generate router from sub-skills
skill-seekers generate-router configs/godot-*.json

# Creates godot-router skill that intelligently routes queries

Step 7: Validate Split Results

# Check sub-skill sizes
for dir in output/godot-*/; do
  echo "$dir: $(find $dir -name "*.md" | wc -l) files"
done

# Verify router coverage
cat output/godot-router/SKILL.md | grep -A 50 "## Sub-Skills"

Recovery Protocol (Archetype 4 Mitigation)

On error:

1. PAUSE - Note which sub-skill failed
2. DIAGNOSE - Check error type:
   • Category overlap → Refine URL patterns
   • Uneven split → Adjust page limits
   • Orphan pages → Add catch-all category
   • Router incomplete → Regenerate after all sub-skills done
3. ADAPT - Modify split configuration
4. RETRY - Re-split affected category (max 3 attempts)
5. ESCALATE - Present split preview, ask user for boundary adjustments

Router Skill Structure

The generated router skill:

# Godot Documentation Router

## Purpose
Route queries to the appropriate specialized Godot sub-skill.

## Sub-Skills

| Topic | Skill | Coverage |
|-------|-------|----------|
| GDScript, C#, scripting patterns | godot-scripting | 8,200 pages |
| 2D graphics, sprites, tilemaps | godot-2d | 5,400 pages |
| 3D graphics, meshes, materials | godot-3d | 9,100 pages |
| Physics, collisions, rigid bodies | godot-physics | 4,300 pages |

## Routing Rules

1. **Scripting questions** → godot-scripting
   - Keywords: script, gdscript, c#, function, variable, class

2. **2D graphics questions** → godot-2d
   - Keywords: sprite, 2d, tilemap, animation2d, canvas

3. **3D graphics questions** → godot-3d
   - Keywords: mesh, 3d, spatial, material, shader, camera3d

4. **Physics questions** → godot-physics
   - Keywords: physics, collision, rigidbody, area, raycast

## Usage

Ask your question naturally. This router will direct you to the appropriate specialized skill.

Example:
- "How do I create a player movement script?" → godot-scripting
- "How do I set up tilemap collisions?" → godot-2d
- "How do I apply materials to a mesh?" → godot-3d

Troubleshooting

Issue	Diagnosis	Solution
Uneven splits	Category size varies	Use hybrid strategy with max_pages
Orphan pages	URL patterns incomplete	Add catch-all or refine patterns
Router confusion	Overlapping keywords	Make routing rules more specific
Too many skills	Over-segmented	Merge related categories
