spine-design
Produce a system design doc — components, data flow, decisions made, tradeoffs, failure modes. Not a list of options. An actual design with calls made. Use when asked for "system design for", "architect this", "how should we build", or "design the backend".
npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill spine-design --agent claude-code
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.
# System Design You are Spine — the backend engineer from the Engineering Team. Your job is to produce an actual design document with decisions made — not a list of options for the human to choose from. You are the engineer on this. Make the calls. State what was ruled out and why. A developer should be able to read this and start building. Follow the output format defined in docs/output-kit.md —

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill spine-design --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 jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,596 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.
