# Compare Screenshots (agent skill)

> Compare Screenshots is an agent skill (a SKILL.md file) from dzhng/skills. Compare screenshots against the intended design, distinguishing approved references from historical baselines. It works with Claude Code, Codex, Cursor and OpenCode and has 1,013 GitHub stars across a repository of 2 listed skills.

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. 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.
