April 26, 2026 · View on GitHub

The WallRun Copilot agent plugin bundles 14 curated signage skills and 2 specialized agents into a package you can install into any VS Code workspace — no need to clone the full monorepo.

What's included

Category	Contents
Agents	`signage-architect` (premium signage design), `wallrun-deploy` (deployment triage)
Skills	Layout system, animation, menu boards, distance legibility, safe layout, state machine, data refresh, content fallbacks, performance budget, placeholder images, BrightSign runtime/packaging/deployment/debugging
Hooks	Advisory preflight check (experimental)
MCP	BrightSign Player Tools server (discover, probe, list, add, remove players) + BrightDeveloper docs

Prerequisites

VS Code Insiders — Copilot agent plugins are a preview feature currently available only in VS Code Insiders. This may change as the feature matures.
GitHub Copilot Chat enabled
Copilot agent plugin support enabled in settings

Installation methods

Option A: Local path (already have the repo)

If you've cloned WallRun, point VS Code at the plugin directory:

Open VS Code Settings (JSON)
Add:

"chat.pluginLocations": {
  "/absolute/path/to/WallRun/copilot-plugins/wallrun-signage": true
}

Reload VS Code

Option B: Install from repo URL

Use the built-in command to install directly from GitHub:

Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
Run Chat: Install Plugin From Source
Enter the repo URL: https://github.com/CambridgeMonorail/WallRun
VS Code clones the repo and discovers the plugin automatically

Option C: Install portable skills only

If you only want the skills (without agents or hooks), use the open skills CLI:

npx skills add CambridgeMonorail/WallRun

Verifying the installation

After installing, open GitHub Copilot Chat and try:

@signage-architect Build a 3-zone layout for 1080p with a ticker and hero

If the agent responds with signage-specific guidance, the plugin is working.

Updating the plugin

The plugin is regenerated from source skills and agents. After pulling new changes:

pnpm plugin:copilot:build

If you installed via Install Plugin From Source, VS Code manages updates when you pull the repo.
