keyvaluesoftwaresystems Skill

Write or narrowly repair one buildable repository LLD from an approved HLD, confirmed repo decisions, and bounded code evidence, including an implementation-complete data model and a frontend-ready API/client contract in concise, skimmable technical English.

keyvaluesoftwaresystems Skill

Generate the cross-repo API/event CONTRACT (OpenAPI) by reconciling the per-stack LLDs — the backend LLD (what it exposes) and the frontend LLD (what it consumes) — into the single boundary both build against. Also derives acceptance criteria and the affected stacks. Reads the LLDs; writes the contract; never edits app code. Front door for /api-contract.

keyvaluesoftwaresystems Skill

Author the backend low-level design (LLD) for a feature — read the relevant backend code to ground the design, then design how the feature slots in — component/sequence design, data model + migration plan, the API/events the backend will expose, error handling, security, observability, and test plan. Writes the LLD doc; never edits app code. Front door for /backend-design.

keyvaluesoftwaresystems Skill

Split an approved frontend scope + contract into a small, ordered, test-first task list with a verification step per task and risk flags. Read-only planning — never edits code.

keyvaluesoftwaresystems Skill

Author the frontend low-level design (LLD) for a feature — read the relevant frontend code to ground the design, then design component/state architecture, routing, the full UI-state matrix, the API it needs to consume, accessibility, performance, i18n, and tests. Writes the LLD doc; never edits app code. Front door for /frontend-design.

keyvaluesoftwaresystems Skill

Review the frontend implementation — UI-state completeness, accessibility, security, resilience, forms, performance, type safety, component quality, state management, responsive/i18n, test gaps. Read-only; writes a review artifact. Front door for /frontend-review.

React 18/19 patterns including hooks discipline, server/client component boundaries, Suspense + error boundaries, form actions, data fetching, state management decision trees, and accessibility-first composition. Use when writing or reviewing React components.

keyvaluesoftwaresystems Skill

Implement an approved frontend scope by consuming the cross-repo contract exactly, with all required UI states, meeting the frontend engineering standards (accessibility, performance, security, i18n, resilience). Edits code within scope only. Front door for /frontend-implement.

Dispatched by review-orchestrator for --testing-practices, --project-conventions, --all, or changed test/e2e/story files.

mrciphersmith Bundle

Use when reviewing frontend code against repository-local conventions commonly captured in CLAUDE.md or similar project guides: React/MobX boundaries, TypeScript strictness, i18n placement, storage wrappers, error handling, styling tokens, Storybook expectations, and local tooling rules. Dispatched by review-orchestrator for --frontend-conventions, --project-conventions, --all, or frontend src/**/*.ts(x) changes when local convention docs exist.
