View upstream skill ↗

Use case and setup notes
Best for
Release handoffs and high-signal completion checks.
Tool requirements
Shell, test, build, or artifact inspection commands appropriate to the project.
Using it with GPT-6

Web Design Guidelines

Interface review guidance covering accessible controls, clear labels, responsive behavior, errors, layout, and practical web UI conventions.

View upstream skill ↗

Use case and setup notes
Best for
Auditing or improving web interfaces and generated frontend code.
Tool requirements
Web source access; no special runtime for the Markdown guidance.
Using it with GPT-6
Use for reviewing frontend source. Browser checks require a separate browser tool in the host.
License
MIT (upstream web-interface-guidelines; agent-skills repo API has no declared license)
Before you start
Guidelines require product context and do not replace browser accessibility testing.

Prioritized PostgreSQL guidance across query performance, connection management, schema design, locking, RLS security, access patterns, and diagnostics.

View upstream skill ↗

Use case and setup notes
Best for
SQL, schema, index, connection-pooling, and RLS reviews.
Tool requirements
PostgreSQL/Supabase schema and query context; no special runtime for core guidance.
Using it with GPT-6
Use as SQL and schema-review guidance in Codex, with the actual PostgreSQL version and workload.
License

UI/UX Pro Max

Design-intelligence skill that searches bundled UI patterns, palettes, typography, accessibility, charts, icons, and frontend-stack guidance before implementation.

View upstream skill ↗

Use case and setup notes
Best for
Web or mobile UI design, review, and responsive frontend refinement.
Tool requirements
Python 3 and the bundled design data and scripts; keep companion files together.
Using it with GPT-6
Use the publisher’s Codex installation target. The linked source uses Claude plugin paths, which need the matching Codex package layout.
License
MIT (upstream SKILL.md metadata; verify current repo)
Before you start
Treat generated design-search output as evidence to inspect, not as a substitute for product context.

official

Frontend App Builder

Official frontend skill for polished apps, dashboards, games, creative websites, redesigns, responsive implementation, and browser verification guided by a design brief.

View upstream skill ↗

Use case and setup notes
Best for
Building or materially restyling user-facing web interfaces.
Tool requirements
Frontend project, browser verification, and image generation when the full upstream workflow calls for it.
Using it with GPT-6
Use with GPT 6 in Codex when browser and image-generation tools are available. The workflow uses those tools for design and visual checks.
Before you start
Full workflow may require imagegen and browser tools; do not promise them on every host.

Reports, PDFs, and Slide Automation

Official artifact skill for structuring and exporting data-rich reports, PDFs, PowerPoint or Google Slides, documents, figures, and technical diagrams with final QA.

View upstream skill ↗

Use case and setup notes
Best for
Producing report, PDF, slide, or document deliverables.
Tool requirements
Document/slide/PDF libraries plus rendering and visualization support as needed.
Using it with GPT-6
Use with file creation and rendering tools in Codex. Google Slides delivery also needs the appropriate connected account.
Before you start
