Use when capturing or re-capturing UI screenshots for a marketing site (FeatureBlock images, email previews, hero posters, OG cards). Reads a YAML spec file that defines source URLs, capture targets, DOM tweaks, and output paths. Uses Playwright for native-browser element screenshots (no html2canvas, no oklab/bg-clip-text workarounds, no animation gotchas). Supports multiple auth strategies — static headers, pre-built storage state, interactive login, or minted JWT — and runs anonymously for public sites. Works headless in CI.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
8 critical findings reported by cisco-skill-scanner. The composite score alone does not reflect this — read the per-scanner reports below.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'brandonhall/marketing-screenshots (screenshot)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'brandonhall/marketing-screenshots (screenshot)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 32 findings across every scanner that examined this package. None of the 8 findings rated critical by their scanner were dismissed.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
10 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Artifact allows shell execution and file system access.
The artifact contains critical command injection vulnerabilities via JavaScript function constructors and child processes in `capture.mjs` and `tweaks.mjs`, enabling shell execution. It also has high-severity findings for data exfiltration through file system access in `mint-jwt.mjs` and `spec-loader.mjs`, which could lead to credential access. Dynamic code execution is also present in `capture.mjs`, and parts of the code exhibit low analyzability.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
