Use when you need to map the application's routes, pages, and components, build reusable Playwright playbooks, or perform a UI/UX audit across the application.
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
# App Navigator
Map your application's UI and build reusable Playwright playbooks for browser-based testing and verification.
**Core principle:** Know your app before you test it. This skill creates a living knowledge base of routes, pages, components, and interactions that other skills (like trust-but-verify) build on.
## When to Use
- Setting up browser-based testing for the first time in a project
- After significant UI changes that may have shifted routes or layouts
- Before running trust-but-verify, if no app-map.md exists yet
- When you need to understand the app's page structure
**Not for:** API-only projects, backend-only changes, or projects without a web UI.
## Invocation
- `/app-navigator setup` -- map the app and write playbooks
- `/app-navigator audit` -- UI/UX audit (v2, not yet implemented)
- If no argument given and no `app-map.md` exists, runs setup mode automatically
## Setup Mode Process
```dot
digraph setup {
"Check credentials" [shape=box];
"Creds in memory?" [shape=diamond];
"Ask user + save" [shape=box];
"Check dev server" [shape=box];
"Server reachable?" [shape=diamond];
"Tell user what to start" [shape=box];

How to install
mdr add buildbetter-app/skills/app-navigator@sha256:6a3bb76be0d58ea3The line at the top of this page pins the label git:20260608.1149f4a, 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.
