Check the visual impact of an edit mid-task with `uiverify check` — render just the components you're touching on the UI Verify fleet and diff them against the real CI baseline, without opening a PR, posting a check, or moving a baseline. Works for every capture method (Storybook, Playwright, Vitest archives, and raw screenshots). Use when a coding agent has changed UI and wants a fast, authoritative "would this pass" answer before pushing — "check my visual changes", "did I break anything visually", "preview this diff", "run uiverify check". Hands off to triage-visual-changes for the pixel review.

Author economical visual tests — full visual coverage in the fewest billable snapshots. Applies to any per-snapshot visual tool (UI Verify, Chromatic, Percy, Playwright screenshots), which all bill and diff per rendered story/test. Use when a component's variants/states are exploding into one snapshot per combination, when the visual-testing bill or noise is driven by snapshot count, or when writing new stories/captures and you want the cheapest layout that still covers every variant. Covers gallery/matrix stories, data-driven states, and the coarse-granularity tradeoff.

Use the ChatJS React Query v5 lazy-prefetch pattern without blocking server rendering. Use when prefetching tRPC queries in Next.js Server Components or changing query dehydration and hydration behavior in apps/chat.

Read before changing any component, page, or styles. Five moves to change UI without silently breaking another screen - reuse before you create, cover every state, check the blast radius, prove it with a visual test, kill flake at the source.

Turn on Cache Components in a Next.js app and resolve the blocking routes it surfaces. Use when the user wants to enable, adopt, or migrate to Cache Components, flip the `cacheComponents` flag, work through a flood of blocking-prerender / instant validation errors, run the `cache-components-instant-false` codemod, or decide between opting routes out with `export const instant = false` and fixing them in place.

Verify Next.js runtime behavior after editing app code. Use this skill to confirm a change actually works in a running app — not just that it compiles or type-checks. Combines /_next/mcp (Next.js's view) with agent-browser (the browser's view). Requires a running `next dev`.

Turn on Partial Prefetching in a Next.js app and work through the insights it surfaces. Use when the user wants to enable or adopt Partial Prefetching, flip the `partialPrefetching` flag, opt routes in with `export const prefetch = 'partial'`, audit `<Link prefetch={true}>` calls, or resolve the link-prefetch-partial and instant-shell-url-data insights.

Review and fix ChatJS Blume documentation and MDX files. Use when checking docs for correctness, broken links, stale examples, unclear prose, or consistency with the implementation.

Decide whether a change warrants new tests and choose proportionate verification. Use before adding tests, when planning validation, or when reviewing whether a proposed test protects meaningful behavior.

Triage a UI Verify build from your coding agent via the UI Verify MCP — bucket a build's changed stories into real regressions vs cosmetic reflow vs rendering noise, summarize the real regressions for a PR comment, and accept baselines in bulk. Use after a UI Verify build reports changes and you want the agent to review, summarize, or accept from the terminal instead of clicking through the dashboard. Triggers - "triage this build", "summarize the visual regressions", "accept all the new baselines".

Make @uiverify/vitest (Vitest browser-mode) captures deterministic so component visual tests stop coming back "changed" without a real change (flaky diffs). Use when setting up or debugging visual tests over Vitest browser-mode component tests, or rendering whole pages (including Next.js App Router pages) in browser mode. Focuses only on the run-to-run variation the capturer can't neutralize from outside your app — above all live/dynamic data, the highest-value step (freeze it with static fixtures and the whole content-noise class disappears), plus the clock, infinite JS animations, and non-Math.random randomness, and the one Vitest-specific trap - capturing before the component has settled.

Discover and use stable per-app ports assigned to a local monorepo worktree. Use when starting, opening, testing, or debugging local apps, or when worktree slots, localhost ports, PORT, app URLs, or .worktree-env.json are involved.

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
