use when you need to verify code changes preserve UI appearance.

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

run `agent-browser diff --help`
`agent-browser diff` compares screenshots, page snapshots or URLs and highlights differences
use a separate baseline worktree if it's easier

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add nicholas-greenwood/agentic-engineering-skills/agent-browser-diff@sha256:5f6ffc2e785d4f90

The line at the top of this page pins the label git:20261029.4ede94a, 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.
