Use when you need information about this project's architecture, tech stack, coding patterns, data model, deployment setup, git workflow, or UX guidelines. Contains comprehensive project documentation including design decisions, technical specifications, and development standards.
Index of every documented @radix-ng/primitives example. Use when implementing a UI feature to find a working, copy-paste-ready Angular pattern built on the primitives. Each component links to a bundled .md file containing the full source of all its examples.
Build correct, accessible UI with @radix-ng/primitives — the signals-first, headless Angular primitive library. Use when implementing Angular components, forms, dialogs, menus, or any UI on top of radix-ng primitives, or when styling them with a custom design system. Use when: "build a … with radix-ng", "use @radix-ng/primitives", "headless Angular component", "style radix-ng with my design system", "Angular accordion/dialog/select/…".
Write or update Storybook stories and docs MDX for a Radix NG primitive following project conventions. Use when: writing stories, updating docs, adding a new story, updating MDX, "обнови сторис", "напиши доки для", "update stories", "add story". Enforces: one-file-per-component rule, ?raw source imports, tailwindDemoDecorator, semantic tokens, docs MDX template.
Test Radix NG primitives across every layer and pick the RIGHT one for a change: Vitest unit (zoneless), jest-axe a11y, Playwright browser regression (apps/visual-regression), SSR (apps/radix-ssr-testing), and perf benches (apps/radix-perf-testing). Enforces the rule that layout / positioning / part-visibility / opens-without-error fixes need a browser test — jsdom can't see them. Use when: writing/fixing/adding a test, "напиши тест", "добавь тест", "почему баг не поймали", "покрой тестом", "write a test", "add a regression test", "verify the fix", choosing a test type, debugging a zoneless / NG0100 / NG0951 / NG0201 test failure, or running any suite.
Angular framework reference for building this signals-first, headless directive library. Consult for API/best-practice details on reactivity (signal, computed, linkedSignal, effect, afterRenderEffect), Signal Forms, signal-based inputs/outputs, host bindings, dependency injection (inject, InjectionToken, providers, injection context, hierarchical injectors), headless accessible component patterns (ARIA), and Vitest testing. Defer to CLAUDE.md for repo-specific tooling — this is an Nx + pnpm monorepo, not an Angular CLI app.
Maintain project documentation in .claude/skills/project-knowledge/: audit, edit, check consistency, track status. Use when: "проверь документацию", "обнови документацию", "аудит документации", "check docs", "audit documentation", "update docs", "проверь базу знаний проекта" For creating documentation from scratch use project-planning skill. For reading docs or explaining concepts, read project-knowledge skill directly.
Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
