Documentation

README

Excerpt

Propose a new change - create the change and generate all artifacts in one step.

I'll create a change with artifacts:

proposal.md (what & why)
design.md (how)
tasks.md (implementation steps)

When ready to implement, run /opsx:apply

Input: The user's request should include a change name (kebab-case) OR a description of what they want to build.

Steps

If no clear input provided, ask what they want to build

Use the AskUserQuestion tool (open-ended, no preset options) to ask:

"What change do you want to work on? Describe what you want to build or fix."

From their description, derive a kebab-case name (e.g., "add user authentication" → add-user-auth).

IMPORTANT: Do NOT proceed without understanding what the user wants to build.

This is the opening of the README. Read the full README on GitHub.
