Verify the Canvas Workspace onboarding case with the local harness. Use when asked to open or test onboard/onboarding/first-run Canvas behavior, capture CDP screenshots, inspect onboarding text or layers, compare the current branch against expected onboarding content, and close the disposable session afterward.
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
# Canvas Onboard Harness ## Overview Use this skill for the specific onboarding case. The goal is to open Canvas in a clean first-run state, verify what onboarding content the current build actually renders, capture screenshot evidence through CDP, and distinguish product regressions from harness or build issues. Use a disposable `temp` profile by default. Onboarding seed logic usually runs only when the store is empty, so reuse of an old `HOME` can hide first-run behavior. ## Standard Check Run from the repository root. 1. Build current code before testing unless the user explicitly wants the existing build: ```bash pnpm --filter canvas-workspace build ``` 2. Open the app directly at the onboarding target with a fresh harness session: ```bash pnpm --filter canvas-workspace harness start --target onboard --profile temp --force --json ``` 3. Confirm CDP and target state: ```bash pnpm --filter canvas-workspace harness status --json ``` Expect `alive: true`, `cdpReady: true`, and a `Pulse Canvas` page target. `start` writes the session only after the visible default canvas has an empty card with three enabled actions and the stored document has no nodes or edges. …

How to install
mdr add hua-bang/pulse-agent/canvas-onboard-harness@sha256:ae7d38551329bc15The line at the top of this page pins the label git:20261016.e9bf52d, 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.
