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.

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.

Scope the Bash tool to specific commands using allowedTools patterns (e.g., Bash(git *) instead of bare Bash). Remove blanket Bash access from allowed_tools lists.

Likely FP if the Bash entry in allowed_tools is part of a constrained configuration that limits commands elsewhere (e.g., via system prompt restrictions).

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.
