Detects downloading scripts piped directly to a shell interpreter
curl -LsSf https://astral.sh/uv/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 -LsSf https://astral.sh/uv/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 -y, --yes, or --auto-approve flags in MCP/skill install commands that bypass user confirmation
install ffmpeg python3-pip -y Remove the -y/--yes auto-confirm flag from MCP server launch arguments. This flag bypasses user confirmation prompts and allows unattended execution of potentially dangerous operations.
Likely FP if the matched text is an isolated flag (-y or --yes) in documentation describing command-line options, not in an actual MCP config.
Detects system-level package installation via brew, apt, yum, or dnf
apt install 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 -LsSf https://astral.sh/uv/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.
