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:
- Analyzing Tool Documentation - Firecrawl documentation, README, API specs
- Applying SKILL.md Pattern - Deterministic output, ternary polarity, SPI guarantee, parallelism
- Generating Custom SKILL.md - Fully functional, production-ready skill
- 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

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?
