+## Skills
+
+**Skills are automatically discovered from a `.skills` directory in your project.**
+
+Skills allow you to define custom capabilities that the agent can reference and use. When you start a new session, Letta Code recursively scans for `SKILL.MD` files and loads any skill definitions found.
+
+### Creating Skills
+
+Create a `.skills` directory in your project root and organize skills in subdirectories:
+
+```bash
+mkdir -p .skills/data-analysis
+```
+
+Each skill is defined in a file named `SKILL.MD`. The directory structure determines the skill ID:
+
+```
+.skills/
+├── data-analysis/
+│   └── SKILL.MD          # skill id: "data-analysis"
+└── web/
+    └── scraper/
+        └── SKILL.MD      # skill id: "web/scraper"
+```
+
+Create a skill file (`.skills/data-analysis/SKILL.MD`):
+
+```markdown
+---
+name: Data Analysis Skill
+description: Analyzes CSV files and generates statistical reports
+category: Data Processing
+tags:
+  - analytics
+  - statistics
+  - csv
+---
+
+# Data Analysis Skill
+
+This skill analyzes data files and generates comprehensive reports.
+
+## Usage
+
+Use this skill to analyze CSV files and generate statistical summaries...
+```
+
+**Skill File Format:**
+
+- **File name:** Must be named `SKILL.MD` (case-insensitive)
+- **Required frontmatter:**
+  - `name` - Display name for the skill
+  - `description` - Brief description of what the skill does
+- **Optional frontmatter:**
+  - `category` - Category for organizing skills (skills are grouped by category in the agent's memory)
+  - `tags` - Array of tags for filtering/searching
+- **Body:** Additional details and documentation about the skill
+
+Skills are automatically loaded into the agent's memory on startup, making them available for reference throughout your session.
+
+### Custom Skills Directory
+
+You can specify a custom skills directory using the `--skills` flag:
+
+```bash
+letta --skills /path/to/custom/skills
+letta -p "Use the custom skills" --skills ~/my-skills
+```
+

 Memory management tools allow you to edit existing memory blocks and query for external memories.
 Memory blocks are used to modulate and augment your base behavior, follow them closely, and maintain them cleanly.
 They are the foundation which makes you *you*.
+
+# Skills
+You have access to Skills—folders of instructions, scripts, and resources that you can load dynamically to improve performance on specialized tasks. Skills teach you how to complete specific tasks in a repeatable way. Skills work through progressive disclosure—you should determine which Skills are relevant to complete a task and load them, helping to prevent context window overload. 
+Each Skill directory includes:
+- `SKILL.md` file that starts with YAML frontmatter containing required metadata: name and description
+- Additional files within the Skill directory referenced by name from `SKILL.md`. These additional linked files should be navigated and discovered only as needed.
+How to use Skills:
+- Skills are automatically discovered on bootup. The Skills directory and any available Skills are stored in the `skills` memory block.
+- Review available Skills from the `skills` block when you are asked to complete a task.
+- If a Skill is relevant, first load the Skill by reading its full `SKILL.md` into context.
+- Then, navigate and discover additional linked files in its directory as needed. Don't load additional files immediately, only load them when needed.
+- When you load / use Skills, explicitly mention which Skills are loaded / used.
+- When the task is completed or when you load new Skills, unload irrelevant Skills by removing them from the context.
+Remember to always keep only the full `SKILL.md` into context for all Skills relevant to the current task. Use additional files as needed.
