stitch-skills
Google Labs Code
Open-source collection of agent skills and plugins for Google Stitch that plug into Codex, Claude Code, Cursor, and Gemini CLI.
Key features
- Cross-Agent Plugin Bundles: Ships stitch-design, stitch-build, and stitch-utilities as marketplace plugins that install into Codex, Claude Code, Cursor, Antigravity, or Gemini CLI.
- Code to Design: Convert frontend code (React, Vue, etc.) into a Stitch design by extracting HTML, applying the design system, and uploading it to a Stitch project.
- Generate Design: Create new screens from text or images, edit existing screens, and produce dark-mode or high-density design variants.
- Design System Management: Upload a DESIGN.md and apply the theme across all screens in a Stitch project.
- Extract Design MD: Scan a codebase and generate a comprehensive DESIGN.md describing the design system directly from source.
- Static HTML Extraction: Capture self-contained static HTML from running web apps with CSS and images inlined for handoff.
- React / React Native / shadcn Codegen: Convert Stitch designs to production-ready React components, React Native code, or shadcn/ui-integrated apps.
- Remotion Walkthrough Videos: Generate video walkthroughs of a Stitch project with smooth transitions and zooming.
Best for
- Migrating a Codebase to a Design System: Upload an existing frontend into Stitch to run a design migration project with consistent tokens and theming.
- Rapid Screen Generation: Product teams generate mobile or web screens from short prompts and iterate on variants without leaving the coding agent.
- Code Handoff from Design: Convert Stitch screens into React or React Native components so engineers can consume the design in the target framework.
- Design System Extraction: Reverse-engineer a DESIGN.md from an existing repo to formalize implicit design tokens and share them across teams.
- Design Reviews and Walkthroughs: Automatically produce video walkthroughs of a project to share with stakeholders and reviewers.
- Agent-Native Workflows: Developers who live inside Claude Code, Cursor, or Codex install Stitch skills locally to drive design work from the same agent they use for coding.
TryCase
TryCase
An AI QA agent that opens your app on every pull request and posts a verdict, captioned video and screenshot back to GitHub.
Key features
- PR-Triggered Runs: Connecting a repository is enough - every pull request marked ready for review starts a test run with no pipeline config.
- Journey Selection From Diff: TryCase reads the changed code and chooses which user flows are actually affected rather than replaying a whole suite.
- Disposable Linux Environments: Each run gets a fresh environment with terminal and browser control, so state from earlier runs never leaks in.
- Video and Screenshot Evidence: Results arrive as a captioned recording plus a screenshot commented on the PR, showing exactly what the app did.
- Bring Your Own AI: Connect Codex through an existing ChatGPT subscription or supply an OpenRouter key and pay your provider directly for inference.
- Agent Skills: Packaged skills teach Claude, Codex, Cursor and other compatible agents to drive TryCase environments without manual setup.
- Parallel Workers: Up to twelve workers per bot run journeys concurrently, with testing time tracked separately for setup, the primary bot and each worker.
- Usage-Based Hour Pools: Monthly plans grant a shared pool of end-to-end testing hours across setup, PRs and retries, with no automatic overage charges.
Best for
- Pre-Merge Verification: Confirm a checkout or signup flow still works before approving a pull request, without pulling the branch locally.
- Visual Regression Review: Catch layout and rendering breakage that unit tests pass over by watching the recorded walkthrough.
- Agent-Written Code Review: Require an AI coding agent to return screenshots and recordings proving its change runs, not just a diff.
- Suite-Free E2E Coverage: Give a small team end-to-end coverage without staffing the maintenance of a Playwright or Cypress suite.
- Demo Clips From Branches: Reuse the captioned videos as short product demos of a feature still sitting on a branch.
- Release Triage: Scan verdicts across several open PRs to decide which changes are safe to batch into a release.
