# Skills Runtime & Self-Evolution

Dewee loads modular `SKILL.md` bundles (`internal/skills/`) with BM25 keyword search. Agents refine their communication style through guardrailed evolution loops.

```bash
# Upload a skill directory
dewee skills upload ./my-skill

# Grant skill to an agent
dewee skills grant agent <skill-id> <agent-id>
```
