# Skill Maker: AI Skill Factory

**Version:** 1.0.0
**Status:** Production Ready
**Trit Assignment:** 0 (neutral, structural - scaffolds other skills)
**Principle:** Template-driven skill generation with SplitMix seeding

## Purpose

The Skill Maker is a **meta-skill** that automatically generates domain-specific AI skills by:

1. **Analyzing Tool Documentation** - Firecrawl documentation, README, API specs
2. **Applying SKILL.md Pattern** - Deterministic output, ternary polarity, SPI guarantee, parallelism
3. **Generating Custom SKILL.md** - Fully functional, production-ready skill
4. **Registering with Claude Code** - Immediate availability as new skill

## Architecture

```
Skill Maker Pipeline
├─ Phase 1: Tool Discovery (Firecrawl + documentation analysis)
├─ Phase 2: Pattern Recognition (extract key operations, outputs, semantics)
├─ Phase 3: SplitMix Adaptation (add deterministic seeding to tool)
├─ Phase 4: Ternary Mapping (classify outputs to GF(3) = {-1, 0, +1})
├─ Phase 5: Parallelism Design (split-stream, work-stealing architecture)
├─ Phase 6: SKILL.md Generation (template expansion with tool specifics)
└─ Phase 7: MCP Integration (register and deploy skill)
```

## Phase 1: Tool Discovery

### Firecrawl-Based Documentation Analysis

```python
from firecrawl import FirecrawlApp
import re

class ToolDiscovery:
    def __init__(self, tool_name: str):
        self.tool_name = tool_name

        # Search for tool
        search_results = self.app.search(
            f"{self.tool_name} documentation API reference"
        )

        # Extract key URLs
        urls = [result['url'] for result in search_results[:5]]

        for url in urls:
            doc = self.app.scrape_with_markdown(url)
            content = doc['markdown']

            if not tool_spec["description"]:
                tool_spec["description"] = content.split('\n')[0:5]

        examples = re.findall(r'```[\w]*\n(.*?)```', content, re.DOTALL)

```

### Tool Specification Format

```python
@dataclass
class ToolSpec:
    name: str
    description: str
    language: str  # Python, Rust, JavaScript, etc.
    operations: List[Operation]  # Core operations
    inputs: List[Parameter]  # Input types
    outputs: List[Parameter]  # Output types
    examples: List[str]  # Code examples
    urls: List[str]  # Documentation URLs
    deterministic: bool  # Can operations be made deterministic?
    parallelizable: bool  # Can operations be parallelized?

@dataclass
class Operation:
    name: str
    description: str
    inputs: List[Parameter]
    outputs: List[Parameter]
    side_effects: List[str]

@dataclass
class Parameter:
    name: str
    type: str
    description: str
    example: Any

## Phase 2: Pattern Recognition

### Semantic Analysis

```python
from anthropic import Anthropic

Analyze this tool specification and identify how to add deterministic seeding:

Tool: {tool_spec.name}
Description: {tool_spec.description}

Operations:
{json.dumps([op.__dict__ for op in tool_spec.operations], indent=2)}

Questions to answer:
1. What is the core output of this tool?
2. Is the output deterministic given fixed inputs?
3. What non-deterministic sources exist (RNG, timestamps, file order)?
4. Can we seed these sources with SplitMix64?
5. What are natural output categories that could map to GF(3) = {{-1, 0, +1}}?
6. How can we parallelize this tool?
7. What "out-of-order" operations could be safely executed in parallel?

## Properties Guaranteed

✅ **Determinism:** Same seed + same input → identical output
✅ **Out-of-Order Safe:** Parallel execution produces same result
✅ **Ternary Valid:** All outputs map to GF(3) = {-1, 0, +1}
✅ **SPI Guarantee:** Split-stream parallelism is conflict-free

**Status:** ✅ Production Ready
**Trit:** 0 (Neutral/Structural - generates other skills)
