+
+## Overview
+
+DBOS Python SDK for building reliable, fault-tolerant applications with durable workflows. Use this skill when writing Python code with DBOS, creating workflows and steps, using queues, using DBOSClient from external applications, or building applications that need to be resilient to failures.
+
+## Structure
+
+```
+dbos-python/
+  SKILL.md       # Main skill file - read this first
+  AGENTS.md      # This navigation guide
+  CLAUDE.md      # Symlink to AGENTS.md
+  references/    # Detailed reference files
+```
+
+## Usage
+
+1. Read `SKILL.md` for the main skill instructions
+2. Browse `references/` for detailed documentation on specific topics
+3. Reference files are loaded on-demand - read only what you need
+
