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 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 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.
Detects pip install of arbitrary packages that modify the host environment
pip install nm Pin all pip packages to exact versions (e.g., pip install package==1.2.3). Use a requirements.txt or pyproject.toml with pinned versions and hash verification.
Likely FP if the match is in documentation showing how to install the skill's own PyPI package.
