Grounds an assistant in your app with assistant-ui copilots. Use when steering behavior with useAssistantInstructions, feeding send-time app state through useAssistantContext({ getContext }), exposing components with makeAssistantVisible(Component, { clickable, editable }), giving the model two-way component state through interactables (unstable_useInteractable for app-scoped panels, unstable_interactableTool inside defineToolkit for thread-scoped artifacts, mounted via AuiConfig({ unstable_interactables: unstable_Interactables() })), registering instructions and tools with aui.modelContext.register, or bridging model context across an iframe with AssistantFrameProvider and useAssistantFrameHost. Legacy Interactables(), useAssistantInteractable, and useInteractableState are deprecated in favor of the unstable_ API. Reach for this when the assistant should read the page, click or edit UI, or update component state. For LLM tools use tools; for runtime and thread state use runtime

Fix or implement a tracker issue end to end from a single command — takes an issue id or a plain problem description (filed first via om-prepare-issue), classifies, then drives the bug autofix chain (om-verify-in-repo, om-root-cause, om-fix, om-open-pr, om-auto-review-pr, om-auto-qa-pr for UI fixes) or the feature route (spec via om-auto-write-spec, built via om-auto-implement-spec). Isolated worktree, claim protocol, clean stops. Use for "fix issue 123" or a pasted problem description.
Review the current Kelos branch, or an explicitly specified PR, issue, or diff, for Kubernetes API and CRD design quality. Use when asked for a Kelos API review, CRD/API compatibility review, Kubernetes API convention review, or review of changes under api/, generated CRDs, examples/, or self-development/ manifests. Default to the current branch when no target is specified. This skill is review-only.
Translates Figma designs into production-ready application code with 1:1 visual fidelity. Use when implementing UI code from Figma files, when user mentions "implement design", "generate code", "implement component", provides Figma URLs, or asks to build components matching Figma specs. For Figma canvas writes via `use_figma`, use `figma-use`.
USE ONLY for (1) two or more projects with repeated MSBuild policy, targets, or package versions, or (2) an existing Directory.Build.props/targets/rsp hierarchy with an import, placement, or layering defect. A one-project repo without an existing Directory.Build file is outside scope; do not load this skill. Covers centralizing shared policy and targets, Directory.Packages.props across projects, parent hierarchy/import structure, props-versus-targets placement, and folder/project exceptions. An existing hierarchy defect remains in scope when only one project is affected. For property value or condition semantics use property-patterns.
