# Resource-scan receipt: anthropics/skills — webapp-testing SKILL.md

A resource-scan receipt is the record of one static check run over one public AI resource — a repository, a gist, a skill file, a script, an MCP server package or a config — at the public URL named on the receipt. The receipt binds to the exact bytes scanned, named by their SHA-256 hash, and is sealed into the public ledger like every other record here. Each receipt carries the published check list with the outcome of every check and the findings in plain language. The analysis is static only: the bytes are read as text and are never executed, installed or run, and nothing is fetched from behind a login. A receipt publishes evidence, never a judgment: the summary line counts how many of the checks flagged, and the reader draws their own conclusion from the findings. Re-scanning the same URL creates a new receipt; the artifact page shows the latest receipt and the history, and when the bytes at a URL change the new receipt is a new version — no receipt is ever edited or overwritten.

### Shell-outs and download-and-execute — pass

No shell-out or download-and-execute patterns were found in the scanned bytes.

### Permission declarations vs behavior — pass

No network, credential or filesystem behavior was observed in the bytes, so there is no permission gap to record.

### Known-bad indicators — pass

None of the scanner's published known-bad indicator patterns matched the scanned bytes.

### Provenance facts (weak signals) — pass

Provenance facts, labeled weak signals — they say where the bytes sit, not what the bytes do: source host: raw.githubusercontent.com; repository: anthropics/skills; bytes scanned: 3913.

Evidence: source host: raw.githubusercontent.com; repository: anthropics/skills; bytes scanned: 3913

## History (1 receipt, 1 version)
