Use when editing rendered UI, dashboard, chart, or any visual artifact (Grafana, Terraform-generated panels, frontend components, plot output) - blocks declaring "done" without an external verification artifact.

What this skill does


# Verify UI Changes Before Declaring Done

## Why this skill exists

In prior sessions the same pattern repeated 20+ times: agent edited a chart /
dashboard / orderbook view, declared it fixed, the user came back with
"still not displaying / now shows No Data / repeated columns / still wrong".
The agent could not see the rendered output, so it kept guessing.

## When this fires

- File path matches `*.tsx`, `*.jsx`, `*.vue`, `*.svelte`, `dashboard*.tf`,
  `panel*.tf`, plot/chart code, `index.html`, or any file that produces a
  visual artifact.
- User uses words like "render", "display", "chart", "dashboard", "panel",
  "orderbook", "table", "plot", "screenshot", "preview", "looks like".

## Required behavior

Before declaring a visual change done, produce a verification artifact and
attach or describe it. Pick the cheapest applicable option:

| Stack | Verification |
|-------|--------------|
| Web frontend | `npm run dev`, hit the page, screenshot OR DOM snapshot (`document.querySelector(...).outerHTML`) |
| Rust plots (plotters/charming) | Run the example, list the output PNG, describe what it should contain |
| Terraform/Grafana | `terraform plan` then describe the resulting panel JSON or take a screenshot from the Grafana URL |
| TUI/CLI | Run with sample input, capture the rendered output |
| Tests pre-existing | Run the visual-regression / snapshot test |

If no artifact is achievable in the current environment, say so explicitly:
"I edited X but cannot verify the render from here - please confirm the
visual is correct before merging." Do not declare the task done.

## What "done" is NOT

- Code compiles -> not done.
- Tests pass -> not done (unless those tests cover the visual).
- "The change should produce the desired output" -> not done.
- A confident summary of what the diff does -> not done.

## Red flag

If you are about to write "this should now display correctly" without having
seen the actual output: stop, run the thing, capture the artifact, then
report.

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

react-native-skia

Included

Design, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.

plaid

Included

Product Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".

nextjs-framer-motion-animations

Included

Adds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
