description	Search, compare, customize, and integrate Nucleo icons for SaaS applications, web apps, and React codebases. Use when Codex needs to choose the best Nucleo icon for a UI task, match an existing icon family or style, generate local SVG or TSX assets, recommend the correct Nucleo React package import, or remember prior icon decisions for a project.

Nucleo Icons

Overview

This skill turns Nucleo into a reliable agent workflow instead of a manual browse-and-guess exercise. Use the CLI as the source of truth for discovery, ranking, React package guidance, and remembered project decisions.

Workflow

1. Run nucleo-icons doctor --json first. Confirm the local Nucleo library, cache, package detection, and NUCLEO_LICENSE_KEY.
2. Search broadly. Run nucleo-icons search "<intent>" --json to get the initial candidate list.
3. Add product context. Run nucleo-icons suggest "<intent>" --usage <kind> --project <path> --json for SaaS-aware ranking.
4. Compare variants when the metaphor is right but the treatment is unclear. Run nucleo-icons variants "<icon>" --json.
5. Decide between package import and local asset. Run nucleo-icons react "<icon>" --project <path> --json for React usage guidance.
6. Install the chosen result. Use install --format svg|tsx|react-import and --remember when the decision should bias future picks.

Selection Rules

• Prefer ui outline 18px for compact SaaS controls, navigation, filters, and settings.
• Prefer core 24px or 32px for empty states, product illustrations, and roomier surfaces.
• Match the project’s existing family and style whenever the codebase already has a direction.
• Use familiar metaphors first. A gear or sliders icon is usually stronger than a novel abstract symbol.
• Avoid mixing families inside the same UI zone unless the existing product already does that intentionally.

React Guidance

• Read references/react-packages.md before recommending package installs or imports.
• Prefer exact package imports only when the mapping is reliable or the project already uses that package.
• Fall back to local TSX or SVG output when package guidance is weak, when the repo avoids icon packages, or when license setup is missing.
• Preserve accessibility by choosing one of:
  • meaningful icon: title or aria-label
  • decorative icon: aria-hidden={true}
