Compare screenshots against the intended design, distinguishing approved references from historical baselines. Use for iterative implementation matching, before/after visual review, objective image telemetry, or checking a lone capture for flat, empty, or badly framed content.

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

# Compare Screenshots

Judge images against the intended result. A user-approved design is the target;
a historical baseline is only an earlier attempt and may be wrong. Metrics locate
differences, never decide correctness. The optional upstream
[design-with-images](https://github.com/dzhng/skills/blob/d51322866ffa298838346960414d18a221b52588/skills/visual/design-with-images/SKILL.md)
describes the full exploration-to-implementation loop; it is not required for
this comparison workflow.

## Workflow

1. **Establish the target.** Use the user-approved reference and stated design
   requirements when available; do not replace them with your own taste. Otherwise
   derive the target from the visual requirement, what the thing depicts in reality
   and the domain skill that owns the look. Write it down in one or two
   concrete sentences ("low sun should cast long shadows east; trees fill the
   canopy; labels stay legible at this zoom").
   - If the right answer isn't clear — competing valid readings, a taste or
     product-intent call, a tradeoff only the owner can settle — **stop and ask
     the user** what the correct answer should be. Show them the comparison.

How to install

The exact contents, by fingerprint

mdr add transitive-bullshit/skills/compare-screenshots@sha256:937e5477e6e69fbc

The line at the top of this page pins the label git:20261018.0333997, 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.
