Skills

Skills are directories containing a SKILL.md file with YAML frontmatter and a Markdown body. They are loaded from ~/.phi/skills/ (or skill_path / PHI_SKILL_PATH) and injected into the agent’s context, letting you give the model reusable procedures:

---
name: My Skill
description: What this skill does
license: MIT
compatibility: claude, openai
---

Instructions the agent should follow when this skill is relevant.

In the TUI, add skills from the palette (skills → list), then submit the message with the selected skills applied.

The system prompt lists skill names only — like MCP server names — so skills do not silently bloat every request.
