# nextcore-skills

> Claude Code plugin marketplace with three plugins distilled from a production product built and run by AI coding
> agents: nextcore-design (UI), nextcore-dev (frontend ↔ backend contract), nextcore-workflow (running agents).

Agents: read AGENTS.md first — it routes "is this useful?" (measure, then recommend), "install it" (one command per
agent harness) and "use it on this task" (size the task, open one file).

## Start here
- [AGENTS.md](AGENTS.md): evaluate → install → use, for any AI coding agent
- Measure + recommend: `npx -y -p github:kennetvn/nextcore-skills nextcore measure` · measure + install what fits: `… nextcore all --agent <claude|cursor|codex|gemini|copilot|windsurf|generic>`
- Found an improvement while using them? AGENTS.md §6 — ask the person, post from their account, anonymised
- [README](README.md): overview for people

## Cases
- [cases/](cases/README.md): production incidents and measurement traps, one file each (Symptom · Cause · Fix · How to catch it · Rule), indexed by layer and stack; [taxonomy](cases/taxonomy.json)

## Contributing
- [CONTRIBUTING.md](CONTRIBUTING.md): what goes where, how to make each kind, what gets closed

## Plugins
- [nextcore-design](plugins/nextcore-design/README.md): size → product discovery → draw → critique → build → validate; slop-check, token-audit, design-card, design-review, spec-check (references: product-discovery, validation)
- [nextcore-dev SKILL](plugins/nextcore-dev/skills/nextcore-dev/SKILL.md): field map → API contract → UI state signals; auth, data, jobs, ops
- [nextcore-workflow SKILL](plugins/nextcore-workflow/skills/nextcore-workflow/SKILL.md): diagnose before patch, evidence, parallel agents, living docs
