Detects downloading scripts piped directly to a shell interpreter
curl
curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | sudo bash Download the script first, inspect it, verify its checksum, then run it. Do not pipe curl/wget output directly to sh/bash. Prefer package manager installs.
Likely FP if the download is from a well-known installer domain (e.g., brew.sh, rustup.rs), though this pattern is inherently risky even with trusted sources.
Detects privilege escalation patterns like setuid, chown root, or sudo with shell commands
sudo bash Avoid depending on packages that could be subject to typosquatting or name confusion. Verify package ownership, check download counts, and audit the package source before adding dependencies.
Likely FP if the flagged package is a well-known, high-download-count package from a verified publisher.
Detects execution of shell script files via bash/sh command or direct invocation
bash
scripts/speedtest-social.sh Replace direct shell script execution with a language-native implementation or a sandboxed executor. If shell scripts must run, restrict them to a vetted allowlist with integrity checks.
Likely FP if the match references running a script that is part of the skill's own repository (e.g., ./setup.sh) with clear, auditable contents.

bash
scripts/speedtest-history.sh Replace direct shell script execution with a language-native implementation or a sandboxed executor. If shell scripts must run, restrict them to a vetted allowlist with integrity checks.

Detects system-level package installation via brew, apt, yum, or dnf
brew install s Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.
Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.
Detects system-level package installation via brew, apt, yum, or dnf
apt-get install c Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.
Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.
Detects downloading binary, archive, or installer files from remote URLs
curl
curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb Verify the integrity of downloaded binaries or archives using SHA-256 checksums or GPG signatures. Pin download URLs to specific versions and avoid fetching from unverified sources.
Likely FP if the download is from github.com or githubusercontent.com for a specific tagged release with documented checksums.
Detects chained commands using shell operators with dangerous operations
curl
curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | sudo Break chained commands into discrete, individually validated steps. Avoid piping untrusted output directly into a shell interpreter.
Likely FP if the matched text is a documentation example showing a common installer one-liner for a well-known tool with a canonical URL.
Detects system-level package installation via brew, apt, yum, or dnf
apt-get install s Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.
