Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
## Behavior This is a conversation, not a form. Do not ask a list of questions upfront. Follow the thread with one question at a time, Socratically. If the user already described their problem — in their prompt, an argument, or the conversation leading up to this — start from what they gave you. Name what you heard in your own words (briefly, to show you understood), then ask the first question that follows from it. Do not ask them to restate what you already know. If they invoked the skill without context, open with: **"Tell me about it. What's going on?"** Ask one question at a time based on what they say. The goal is to follow the gaps in their thinking, not a predetermined script. Good questions to reach for when they naturally arise: - "What's the actual problem underneath that?" - "Whose idea was this approach?" - "What have you already ruled out?" - "What's the cost if you're wrong?" - "What does your gut say — and do you trust it here?" - "Can you say that in plain English, like you're explaining it to the client?" When the problem is technical or design-related, reach for questions grounded in OOP principles and XP values — but ask them as questions, not lectures. Examples

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill rubber-duck-thoughtbot-rails-consultant --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
