Browser automation. MUST invoke before calling Playwright. Use when browsing websites, checking UI, filling forms, or automating web workflows.

What this skill does


# Browsing

**ALWAYS use a subagent for browser tasks.** Never call browser tools directly in main context — the snapshots consume thousands of tokens per page.

```
Task tool config:
  subagent_type: general-purpose
  model: haiku
```

The subagent does all navigation and interaction, then returns a concise summary.

Sessions persist per project. All tool calls in a conversation share one browser instance.

## Headed Browser

When the user needs to see or interact with the browser (OAuth, CAPTCHAs, login), open a headed browser sharing the same profile. Close the headless browser first with `browser_close`, then launch via Bash with `run_in_background: true`:

```js
const pw = require('<playwright-path>');
(async () => {
  const ctx = await pw.chromium.launchPersistentContext('<profile-path>', {
    headless: false, channel: 'chrome',
    args: ['--disable-session-crashed-bubble', '--hide-crash-restore-bubble']
  });
  const page = ctx.pages()[0] || await ctx.newPage();
  await page.goto('<url>');
  await page.waitForEvent('close').catch(() => {});
  await ctx.close();
})();
```

To find the values:
- **playwright-path**: `find ~/.npm/_npx -path '*/@playwright/mcp' -type d` → sibling `playwright` package
- **profile-path**: `~/Library/Caches/ms-playwright/mcp-chrome-<hash>` where hash = first 7 chars of SHA-256 of project root path

The script waits in the background until the user closes the window, then cleans up so headless can resume.

## Tips

- `browser_fill_form` for multiple fields, not `browser_type` per field
- Screenshots to check visuals (saves tokens), snapshots when you need refs
- Cache refs from first snapshot, reuse for subsequent interactions
- On token limit errors, output is auto-saved to a file — use Bash to extract what you need

## Workflows

**Check UI:** Navigate → screenshot → analyze

**Submit form:** Snapshot (get refs) → `browser_fill_form` → click submit → screenshot (verify)

**Debug visuals:** Full-page screenshot → element screenshot → console messages

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.
