Documentation

README

Excerpt

Implement tasks from an OpenSpec change.

Input: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.

Steps

Select the change

If a name is provided, use it. Otherwise:
- Infer from conversation context if the user mentioned a change
- Auto-select if only one active change exists
- If ambiguous, run openspec list --json to get available changes and use the AskUserQuestion tool to let the user select
Always announce: "Using change: " and how to override (e.g., /opsx:apply <other>).

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