+# Crimson Leaf — Skills Catalog
+
+Skills are context-sensitive reference documents injected into an agent's prompt
+when a template declares a `skills:` array. They provide technical knowledge
+without permanently inflating RAG storage.
+
+## Available Guides
+
+| Path | Purpose | Used by |
+|------|---------|---------|
+| `guides/PAETemplateGuide.md` | How to write PAE-Lang YAML templates | `write_template.yml` |
+| `guides/PAEAgentGuide.md` | How to create agent.yml and identity.md files | `hire_agent.yml` |
+| `guides/CorporateCharterGuide.md` | How to design a constitutional charter | `create_company.yml` |
+
+## How Skills Work
+
+1. A template declares `skills: ["guides/PAEAgentGuide.md"]` at the top level.
+2. At prompt assembly time, the pipeline fetches each file from `pae/{company_slug}/skills/{path}`.
+3. Content is injected as the `*** SKILLS & GUIDES ***` section in the agent's prompt.
+4. The agent reads the guide as authoritative reference material for the current task.
+
+Skills are company-sovereign — each company maintains its own skills library in its own repo.
