TOOLID=responsive-route-snapshotter. Zero-dependency Node 22+ auditor of two pre-captured local route screenshot manifests. It does not launch Playwright, drive a browser, capture images, or save new screenshots. This is the offline scope adaptation of the original capture-oriented matrix row. A separate capture process must supply both manifests and their image files. The tool reads and hashes those files, compares controlled runs, and emits a deterministic JSON report.
This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+; inspect the source before using it on your own files.
Run the checked-in example
node bin/responsive-route-snapshotter.mjs --root examples/pass --baseline baseline.json --current current.json
node bin/responsive-route-snapshotter.mjs --root examples/fail --baseline baseline.json --current current.json
npm run checkRead the result
The examples exit 0 and 1. --help prints usage; --human adds a terse stderr summary. The library exports TOOLID, LIMITS, and async compareSnapshots(baseline,current,{readScreenshot,now}). The direct library callback is trusted evidence; only the CLI verifies that image bytes came from a regular local file whose realpath stays inside --root. No screenshot read occurs without the supplied callback. The CLI never writes or fetches.
Where this check stops
This local walkthrough does not establish the state of a live production system or replace the limits documented in the repository.
Before adapting the command to your own workflow, review the accepted inputs, exit codes and safety boundaries in the README.
