Web & Frontend

lerianstudio Skill

Checking frontend quality against changed UI via ring:qa-frontend in accessibility, visual, e2e, or performance mode and aggregating pass/fail verdicts. Use when a frontend change needs standalone a11y, visual-snapshot, Playwright e2e, or Lighthouse/Core-Web-Vitals validation outside the dev cycle. Skip for backend-only or non-UI work, or inside ring:running-dev-cycle-frontend, which already runs these in Gate 0.

lerianstudio Bundle

Mapping a Go service's Service -> Module -> Resource hierarchy for dispatch-layer registration: detects modules and per-module PostgreSQL/MongoDB/RabbitMQ resources, database names, and shared databases, generates MongoDB index migration pairs (.up.json/.down.json), detects existing Postgres migrations, emits an HTML report, and offers opt-in S3 upload. Use before ring:adding-multi-tenancy on a new service. Skip for non-Go projects.

anntnzrb Bundle

Use when building or reviewing truthful, accessible data visualizations, charts, dashboards, or React visualizations.

ngxtm Bundle

SSG, SSR, ISR, Streaming, and Partial Prerendering (PPR).

ngxtm Bundle

File-system routing, Layouts, and Route Groups.

lerianstudio Skill

Planning a backend refactor: audits an existing Go or TypeScript backend against Ring/Lerian standards and produces a prioritized task list (findings.md + tasks.md) ready for ring:running-dev-cycle. Plans only — no edits. Use when an existing backend service needs to meet standards or an audit is requested. Skip for greenfield projects, single-file fixes, or frontend (use ring:planning-frontend-refactor).

lerianstudio Skill

Validating that UX specifications are complete before technical design: a read-only checklist over wireframes, states, responsive behavior, accessibility, and component-library alignment, emitting a DESIGN VALIDATED / NEEDS REVISION verdict to design-validation.md. Standalone utility — run after a product-designer pass and before the TRD when the feature has UI; the pre-dev orchestrators recommend it when the feature has UI. Use to check UI design completeness. Skip for backend-only, API-only, or no-UI work.

lerianstudio Skill

Running the frontend (React/Next.js/TS) dev cycle from a plan.md (ring:writing-plans format; legacy tasks.md only for in-flight cycles) or backend handoff: drives frontend agents through Gate 0 TDD plus accessibility/visual/E2E/perf checks, Gate 7 parallel review, and Gate 8 user validation, with rolling-wave phase boundaries. Use when starting or resuming a gated frontend dev cycle. Skip for backend (use ring:running-dev-cycle) or docs-only work.

lerianstudio Skill

Pinning an explicit versioned dependency manifest (dependencies.md plus PROJECT_RULES.md): exact package versions, CVE and license checks, compatibility matrices, and per-component cost analysis against Ring Standards. Gate 6 of ring:planning-large-features; runs after ring:designing-data-model, before ring:writing-plans. Use when the schema is validated and you are about to lock products and versions. Skip for Small Track or when versions are already locked.

lerianstudio Bundle

Auditing a service's production readiness against Ring engineering standards across base dimensions plus a conditional multi-tenant dimension, then emitting a scored report and an HTML dashboard. Use before production deploy, periodic review, onboarding, or a major release. Skip for prototypes, libraries, or single-dimension checks.

lerianstudio Skill

React composition patterns that scale. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or during architecture review. Skip for simple components with 1-2 props or non-React code.

rwilson504 Skill

Generate publication-quality PNG/GIF/MP4 renders from build123d models for documentation sites, README hero shots, and embedded HTML images. USE FOR: hero/isometric renders, web-optimized PNGs, exploded views, cross-section/cutaway renders, animated turntables, color preservation from build123d Color() tags, transparent or dark-theme backgrounds, HTML <img>/<picture> embedding patterns, documentation render pipeline, headless render with trimesh + pyvista, render PCB assembly, render enclosure with components.

rwilson504 Skill

Export named, colour-tagged GLB component maps from build123d so a human and an AI can name parts of a model out loud ("make the blue plates thicker") and inspect them in a glTF viewer. USE FOR: colour in STL, does STL support colour, name parts in a viewer, GLB hierarchy, glTF node names, component map, assembly view, interference check, view model in VS Code, shared vocabulary for design review.

ngxtm Bundle

Mutations, Form handling, and RPC-style calls.

lerianstudio Skill

Validating a completed task against its acceptance criteria, mapping each AC to evidence, and gating completion on explicit user sign-off (self-approval prohibited). Gate 5 of ring:running-dev-cycle / ring:running-dev-cycle-frontend, run at task cadence after ring:reviewing-code. Use when implementation and tests are done and you need approval to close the task. Skip outside a dev-cycle, or for doc-only or non-code tasks.

pmarashian Skill

Ensures Next.js 15 dynamic route parameters are properly awaited. Checks for missing await on params destructuring and provides automatic fixes.

pmarashian Skill

Cookie-based auth from a different origin (e.g. frontend on 3001, backend on 3000) requires Access-Control-Allow-Credentials true and a specific Access-Control-Allow-Origin (not *). If framework middleware does not apply to API routes, add CORS headers in the route handler. Use when debugging cross-origin cookie/session issues.

Stream Deck property inspector (PI) UI: HTML in *.sdPlugin/ui/, sdpi-components web components (sdpi-item / textfield / select / checkbox / range / file / password / color / button etc.), streamDeckClient (setSettings, getSettings, send, onDidReceiveSettings, onSendToPlugin), action vs global settings, sending sendToPropertyInspector from plugin, debugging at localhost:23654, security (never store secrets in action settings — use global). USE FOR: building an action configuration UI, sdpi-components, web components for PI, settings persistence patterns, plugin↔PI messaging, secure token storage, PI ↔ plugin handshake on open, dropdowns populated from plugin (e.g. fetched device list), zod validation of settings.

sitaggart Bundle

Generate an interactive PR review walkthrough as an HTML page. Fetches PR data via gh API, categorizes files into core vs mechanical changes, adds reviewer annotations, and renders diffs with moved-code detection. Use when the user pastes a GitHub PR URL and asks for a review, walkthrough, or summary, or says "review this PR".

pmarashian Skill

For Next.js App Router, use request.formData() and stream/parse the file (e.g. CSV) in the route handler. Do not use Express-style middleware (e.g. multer) in API routes—it can block the request pipeline and cause hangs. Use when implementing file upload in Next.js API routes.

kesslerio Skill

Use the Slack tool to react, pin/unpin, send, edit, delete messages, or fetch Slack member info.

sitaggart Bundle

Apply TypeScript and React code-shape taste for implementation, review, refactor, and quality-gate tasks. Use when TypeScript or React changes involve typed contracts, helper boundaries, domain cores, IO or UI adapters, schemas, reducers, selectors, premature abstractions, speculative guards, maintainability smells, courier objects, JSX business logic, casts, useEffect, effect soup, or over-engineering.
