 ### Skills
 
-Mom can write custom CLI tools to help with recurring tasks, access specific systems (email, calendars, web search, CRM/CMS platforms, issue trackers, Notion, project management tools), or process data (generate charts, Excel sheets, reports, etc.). You can attach files and ask her to process them with a skill, or let her pick the right tool for the task. Skills are stored in:
-- `data/skills/`: Global tools available everywhere
-- `data/<channel>/skills/`: Channel-specific tools
+Mom can install and use standard CLI tools (like GitHub CLI, npm packages, etc.). Mom can also write custom tools for your specific needs, which are called skills.

+Skills are stored in:
+- `/workspace/skills/`: Global tools available everywhere

 Each skill has a `SKILL.md` file with frontmatter and detailed usage instructions, plus any scripts or programs mom needs to use the skill. The frontmatter defines the skill's name and a brief description:

+#### Creating a Skill
+
+You can ask mom to create skills for you. For example:
+
+> "Create a skill that lets me manage a simple notes file. I should be able to add notes, read all notes, and clear them."
+
+Mom would create something like `/workspace/skills/note/SKILL.md`:
+
+```markdown
+---
+name: note
+description: Add and read notes from a persistent notes file
+---
+
+# Note Skill
+
+Manage a simple notes file.
+
+## Usage
+
+Add a note:
+\`\`\`bash
+bash {baseDir}/note.sh add "Buy groceries"
+\`\`\`
+
+Read all notes:
+\`\`\`bash
+bash {baseDir}/note.sh read
+\`\`\`
+
+Clear all notes:
+\`\`\`bash
+bash {baseDir}/note.sh clear
+\`\`\`
+```
+
+And `/workspace/skills/note/note.sh`:
+
+```bash
+#!/bin/bash
+NOTES_FILE="$HOME/.notes.txt"
+
+case "$1" in
+  add)
+    echo "- $2" >> "$NOTES_FILE"
+    echo "Note added"
+    ;;
+  read)
+    cat "$NOTES_FILE" 2>/dev/null || echo "No notes yet"
+    ;;
+  clear)
+    rm -f "$NOTES_FILE"
+    echo "Notes cleared"
+    ;;
+  *)
+    echo "Usage: note.sh {add|read|clear}"
+    exit 1
+    ;;
+esac
+```
+
+Now, if you ask mom to "take a note: buy groceries", she'll use the note skill to add it. Ask her to "show me my notes" and she'll read them back to you.

 ### Events (Scheduled Wake-ups)
 
 Mom can schedule events that wake her up at specific times or when external things happen. Events are JSON files in `data/events/`. The harness watches this directory and triggers mom when events are due.
