What This Command Does

In plain English: You've built a workflow in Dex that works well. This command scans your vault, identifies what you've customised, and writes a methodology document describing how it works. That document can be published to heydex.ai/diff so others can adopt a similar setup using /diff-adopt.

When to use it:

You want to share a workflow with someone else
You want to document how a part of your system works
You want to package your setup for your team

How to run it:

/diff-generate "my meeting prep workflow"
/diff-generate

Arguments

$ARGUMENTS: Optional description of the workflow to package.

If provided: used to identify which components belong to this workflow
If omitted: scans everything custom and asks what to package

Process

Step 1: Discover Customisations

Scan these locations for custom components:

.claude/skills/          - custom or modified skills
.claude/hooks/           - custom hooks
CLAUDE.md                - custom sections
.claude/CLAUDE.md        - local extensions

To identify what's custom vs. baseline dex-core:
