Build UI pages and extensions for Falcon Foundry apps using React or Vue with the Shoelace design system and Foundry-JS. TRIGGER when user asks to "create a UI page", "build a UI extension", "add a Shoelace component", "call an API from the UI", runs `foundry ui pages create` or `foundry ui run`, or needs help with Vite config, Foundry-JS, or Falcon console theming. DO NOT TRIGGER for backend functions, workflow YAML, or collection schemas.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Foundry UI Development > Build UI with Shoelace components using the `falcon-shoelace` theme (not vanilla Shoelace or raw HTML), and load both the dark and light theme stylesheets so it matches the Falcon console. Use `foundry ui run` for live development, and apply the iframe security patterns to every extension. > **Part of a suite.** If `development-workflow` has not already run, and this is a new app or its first capability, load the `development-workflow` skill first — it owns the CLI prerequisite check, scaffolding order, and manifest coordination. Falcon Foundry UI pages and extensions use React or Vue with the Shoelace design system (Falcon-themed) and Foundry-JS for platform integration. ## Pages vs Extensions If the user doesn't specify page or extension, **ask which they prefer** before scaffolding. Present this table to help them decide: | | UI Pages | UI Extensions | |---|---|---| | **What** | Standalone applications | Console-embedded components | | **Where** | Full-page view in Falcon console | Sidebar widget in detection/host/incident pages | | **Sockets** | N/A | One per extension (see socket table below) | …

How to install
mdr add crowdstrike/foundry-skills/ui-development@sha256:7ad0d7834e6c6fdfThe line at the top of this page pins the label v1.7.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
