How to use
- Copy the installation command and review the source package before installing it in your own agent environment.
- Check the source document for required tools, credentials and supported hosts.
- Describe your input and desired deliverable; review the output against the source material.

- Installation does not include a model subscription, API allowance or permission to access your files.
- Repository stars and installation counts describe activity, not an independent quality or security test.

Project Architecture Guardrails
Activation Contract
Load this skill before changing UI, layout, component structure, state flow, theming, data display, or the server/client boundary of a Next.js or Astro app.
Hard Rules
- Detect the framework from the project before acting; never assume it.
- Keep rendering server-first. Add client-side code only when the interaction cannot work without it, and keep that surface as small as possible.
- Read the installed framework's own docs before changing framework APIs or project structure.
- Follow
DESIGN.mdfor visual and UX decisions when it exists. - Build from existing shadcn primitives and semantic tokens before writing custom markup or styles; load
shadcn-component-boundarieswhen it is installed. - Make loading, empty, and error states explicit for every data display.
- Add tests proportional to risk, using the test tooling the project already has.
Decision Gates
| Project signal | Framework | Guidance |
|---|---|---|
next in package.json dependencies, or a next.config.* file | Next.js | references/next.md |
astro in package.json dependencies, or an astro.config.* file | Astro | references/astro.md |
| Both or neither | Unknown | Stop and ask which app the change targets |
Execution Steps
- Read
package.jsonand list the root config files to detect the framework. - Load the matching reference and apply its boundary rules.
- Search existing components, routes, and styles before creating new ones.
- Implement the change with the smallest client-side surface that works.
- Answer the pre-close checklist, then load
project-min-evaluationwhen it is installed, or run the project's quality scripts.
Pre-close checklist:
- Did the change add unnecessary client-side surface?
- Does it follow
DESIGN.md? - Are loading, empty, and error states explicit?
Output Contract
Report the detected framework, every server/client boundary added or moved (with its reason), and the checklist answers.
