## What is OntoSkills?
OntoSkills transforms natural language skill definitions into **validated OWL 2 ontologies** β queryable knowledge graphs that enable deterministic reasoning for AI agents.
**The problem:** LLMs read skills probabilistically. Same query, different results. Long skill files burn tokens and confuse smaller models.
**The solution:** Compile skills to ontologies. Query with SPARQL. Get exact answers, every time.

## Why OntoSkills?
| Problem | Solution |
|---------|----------|
| LLMs interpret text differently each time | SPARQL returns exact answers |
| 50+ skill files = context overflow | Query only what's needed |
| No verifiable structure for relationships | OWL 2 formal semantics |
| Small models can't read complex skills | Democratized intelligence via graph queries |
**For 100 skills:** ~500KB text scan β ~1KB query
