What it does
Visual Regression is an agent skill from WrongStack/WrongStack. Detect unintended UI changes with reproducible rendered screenshots and reviewed baselines. Use when adding screenshot checks or investigating layout/theme regressions; do not approve a changed image merely to make the test green.
Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Visual regression testing. The repository describes itself as: An AI coding agent that reads your code, edits files, runs commands, and reasons through bugs — across a terminal REPL, a full-screen TUI, and a browser UI, while you keep your… The licence is MIT.
When your agent uses it
- Adding screenshot checks
- Investigating layout/theme regressions
- Do not approve a changed image merely to make the test green
Example prompts
- “/visual-regression”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Pin viewport, browser, device scale, locale, theme, fonts, test data and rendered state.
- Wait for actual readiness: fonts/assets/data and known animation completion. Arbitrary sleeps make noisy baselines.
- Mask only intentionally variable content, with a documented reason; masking the changed feature defeats the test.
- Separate antialiasing/environment noise from a meaningful geometry, content or state change.
- Review each changed baseline against the requested outcome and prior image before accepting it.
- Keep screenshot assertions alongside behavioral checks; pixels alone do not prove accessible or functioning controls.
What it can do on your machine
Read from SKILL.md and the folder at commit a744bdc. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
playwright.devstorybook.js.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Visual Regression loads about 750 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 269 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Visual Regression
Selection card
- Task: Compare rendered UI states against screenshot baselines. / TR: Render edilmiş arayüzü ekran görüntüsü baseline ile karşılaştır.
- Start: Identify the target surface, reference, user task and existing tokens.
- Finish: apply the acceptance checks below; report observed results and unresolved constraints.
Overview
Detect unintended UI changes with reproducible rendered screenshots and reviewed baselines.
Current checked targets: Playwright 1.64.0 and Storybook React 10.6.1 (2026-10-09). Refresh registry and browser/tool compatibility before installation.
Rules
- Pin viewport, browser, device scale, locale, theme, fonts, test data and rendered state.
- Wait for actual readiness: fonts/assets/data and known animation completion. Arbitrary sleeps make noisy baselines.
- Mask only intentionally variable content, with a documented reason; masking the changed feature defeats the test.
- Separate antialiasing/environment noise from a meaningful geometry, content or state change.
- Review each changed baseline against the requested outcome and prior image before accepting it.
- Keep screenshot assertions alongside behavioral checks; pixels alone do not prove accessible or functioning controls.
Workflow
- Choose representative routes/components and the states most likely to regress.
- Capture a deterministic baseline through the configured browser/story workflow.
- Inspect the diff image and trace the owning component/theme change.
- Fix the source or accept an intended baseline change with evidence.
- Rerun the same conditions, then the affected interaction tests.
Before returning
Inputs and baseline identity recorded; differences inspected; masking justified; intended changes distinguished from regressions.
Sources
Versioned facts checked 2026-10-09; refresh authoritative sources before new installs/upgrades. Playwright snapshots, Storybook visual testing.
Skills in scope
- testing — behavioral and failure-path verification.
- design-critique — rendered evidence and ranked findings.
- accessibility — keyboard and assistive interaction.
