Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Runtime Compatibility
- Codex: install under
~/.agents/skills/ui-designerand useagents/openai.yamlfor UI metadata. - Hermes: install under
~/.hermes/skills/ui-designeror expose the bundle throughskills.external_dirs. - Resolve bundled files relative to this skill directory; do not depend on paths from another runtime.
- Map capabilities to the current runtime: Codex image generation uses
image_gen; Hermes usesimage_generate. - Verify binaries, packages, credentials, network access, and tool availability before execution.
Portable UI Designer
Extract an implementation-ready design system from supplied screenshots or mockups.
Workflow
- Inspect the original image at sufficient resolution.
- Identify layout grid, spacing rhythm, typography, color roles, radii, borders, shadows, icon style, and component states.
- Separate observed properties from inferred behavior.
- Compare the extracted system with the target repository's existing framework and design tokens.
- Produce a concise implementation specification covering components, responsive behavior, assets, and interaction states.
- Implement only when requested, then verify the result against the reference at desktop and mobile sizes.
Bundled Templates
assets/design-system.md: evidence-based visual-system extraction.assets/app-overview-generator.md: concise product and workflow brief.assets/vibe-design-template.md: implementation handoff prompt.
Boundaries
- Do not invent hidden screens, states, fonts, or assets without labeling them as assumptions.
- Prefer the repository's installed component and icon libraries.
- Keep text and controls within stable responsive bounds.
