Share state between components that don't have a direct parent-child parameter relationship, using cascading values, scoped services with change events, or CascadingValueSource via DI. USE WHEN the user needs a CascadingParameter or CascadingValue that works across render mode boundaries, a shopping cart or notification count accessible from multiple pages, a theme or user preference cascaded app-wide, or when components in different parts of the tree must react when shared data changes.

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
# Coordinate Components ## Step 1 — Read AGENTS.md Read `AGENTS.md` at the workspace root to learn the project's conventions before making changes. ## Step 2 — Decide the scope | Need | Mechanism | When to use | |------|-----------|-------------| | Subtree (same render mode) | `CascadingValue` component | Theme, layout config within a layout | | App-wide (all render modes) | `CascadingValueSource<T>` via DI | Current user, feature flags, theme shared globally | | Mutable shared state within a circuit | Scoped service + `Action` event | Shopping cart, notification count, selected filters | For parent→child one level: use `[Parameter]` / `EventCallback` (see `author-component` skill). For persisting state across prerender→interactive: see `support-prerendering` skill. ## Workflow (quick reference) 1. Choose the mechanism from the table in Step 2 2. If crossing render mode boundaries → use `CascadingValueSource<T>` (Step 4) 3. Register in `Program.cs` with `AddCascadingValue(...)` and `isFixed: false` 4. Consume via `[CascadingParameter]` in child components 5. Update via `NotifyChangedAsync(newValue)` — never page reload …

How to install
mdr add dotnet/skills/coordinate-components@sha256:38d12bcb9340c722The line at the top of this page pins the label git:20260525.198e58c, 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.
