+# Crimson Leaf Research — Skills Catalog
+
+Skills are context-sensitive reference documents injected into an agent's prompt
+when a template declares a `skills:` array. They provide domain expertise and
+methodology reference without permanently inflating RAG storage.
+
+## Available Guides
+
+| Path | Purpose | Used by |
+|------|---------|---------|
+| `guides/ResearchMethodGuide.md` | Evidentiary research discipline, source assessment, confidence rating | `research_brief.yml`, `intelligence_report.yml` |
+| `guides/IntelligenceFormatGuide.md` | Report structure, analytical tone standards, section requirements | `intelligence_report.yml` |
+
+## How Skills Work
+
+1. A template declares `skills: ["guides/ResearchMethodGuide.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.
