Detects downloading scripts piped directly to a shell interpreter
curl -fsSL https://tailscale.com/install.sh | sh 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 patterns of downloading and piping to shell execution
curl -fsSL https://tailscale.com/install.sh | sh Download the file first, verify its integrity (checksum, signature), inspect it, then run it. Prefer package managers over raw downloads. Never fetch-and-run in one step.
Likely FP if the target is a well-known installer (e.g., rustup, Homebrew) from its canonical HTTPS domain, though the pattern is inherently risky.
Detects patterns of downloading and piping to shell execution
curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash Download the file first, verify its integrity (checksum, signature), inspect it, then run it. Prefer package managers over raw downloads. Never fetch-and-run in one step.

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 skills fetching external URLs to use as runtime instructions
curl -fsSL https://raw.githubusercontent.com + rules Pin the downloaded resource to a specific version or commit hash, and verify its integrity with a checksum (SHA-256). Avoid fetching scripts or binaries from arbitrary URLs at runtime.
Likely FP if the download URL points to a well-known CDN or package registry (e.g., npmjs.com, pypi.org) and is pinned to a specific version.
Detects privilege escalation patterns like setuid, chown root, or sudo with shell commands
sudo chmod 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 system-level package installation via brew, apt, yum, or dnf
apt install -y f 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 chained commands using shell operators with dangerous operations
curl -fsSL https://tailscale.com/install.sh | sh 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.

curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash 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 global installation of packages which affects the host system
npm install -g o Replace npm install -g with a local install (npm install --save-dev) or use npx with a pinned version. Global installs modify the system and risk supply chain attacks.
Likely FP if the global install is for a well-known CLI tool (e.g., typescript, eslint) in setup documentation, though the supply chain risk remains real.
Detects execution of shell script files via bash/sh command or direct invocation
sh /usr/local/bin/openclaw-health-monitor.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.
