Create Custom Skill

Create your own skill that's protected from Dex updates.

How It Works

When you create a skill with this command, Dex automatically:

1. Appends

   -custom

   to the folder name (so it's never overwritten by updates)
2. Creates the proper SKILL.md structure
3. Sets up optional folders for scripts, references, and assets

Process

Step 1: Get Skill Details

Ask the user:

What should this skill do?

Give me:
1. A short name (e.g., "meeting-notes", "weekly-report")
2. What it should help you with (1-2 sentences)

Step 2: Create the Skill

Skill folder:

.claude/skills/{name}-custom/

The

-custom

suffix is automatic - don't let the user add it themselves.

Create SKILL.md:

---
name: {name}-custom
description: {user's description}
---

# {Title Case Name}

{User's description expanded into a helpful intro}

## Process

### Step 1: [First Step]

[Instructions for what to do]

### Step 2: [Second Step]

[Instructions for what to do]

## Notes

- This is a custom skill, protected from Dex updates
- Edit `.claude/skills/{name}-custom/SKILL.md` to modify

Step 3: Confirm

✅ Created skill: /{{name}}-custom

Your skill is ready to use. Run /{name}-custom to try it.

**Protected from updates:** The -custom suffix means Dex updates
will never overwrite this skill. It's yours to customize.

**To edit:** Modify .claude/skills/{name}-custom/SKILL.md

Examples

User: "I want a skill for preparing board updates"

Result:

• Folder:

  .claude/skills/board-update-custom/

• Invoke with:

  /board-update-custom

• Protected from all Dex updates

User: "Create a skill called weekly-standup-custom"

Response: "I'll create that as

weekly-standup-custom

- you don't need to add '-custom' yourself, I do that automatically. Want me to proceed with just 'weekly-standup'?"

Tips

• Keep skill names short and descriptive
• Use hyphens, not spaces or underscores
• The skill can reference other files in its folder (scripts/, references/, assets/)
