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
# Security Best Practices ## Avoid Remote Pipe Execution A common dangerous pattern is using `curl http://example.com/script.sh | bash` to download and execute scripts in one step. **Why is this dangerous?** - No opportunity to review the code before execution - The remote server could serve different content to different users - Man-in-the-middle attacks can inject malicious code **Safe alternative:** 1. Download the script first 2. Review its contents carefully 3. Only then execute it if it looks safe Always verify the integrity of downloaded scripts using checksums or signatures.

How to install
mdr add bruc3van/agent-skills-guard/doc-curl-antipattern@sha256:b9be23586a567c31The line at the top of this page pins the label git:20260609.08d2b92, 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.
